Osmosis Science Project

Magriet — Fri, 26 Feb 2010 13:48:17 +0000

There are many variations on the well know “flower changing color” science project. It is always a fun and very visual science fair project for kids to do. If you do not have a lot of time, this is a good one to try as it can be done in a relatively short time.

If you do not have any time left over at all, do go and have a look at 24 Hour Science Projects as you will get science fair projects there that you can do in 24 hours or less! Complete projects with all the details you need.

For a fun project that also uses osmosis as a part of the project have a look at Elementary Science Fair Projects: Sweet or Salty Flowers?

Now for our fun osmosis science fair project; the Green Highways project:

The purpose of the project is to show how plants carry nutrients and water to all the parts of the plant. Here is a fun way to show how it happens.

Here’s what you will need:

1 Fresh stalks of celery
2 Glasses of water
Red food coloring
A knife (let an adult help you with this)

This is what you have to do:

Put the two glasses of water next to each other
The one glass is going to be your control (do you know what a control is?)
Color the water in the one glass dark red by dropping four to five drops of red food coloring into it
Now you have to cut off the dried bottom part of the stalk of celery
Cut the stalk in half from the bottom to the leaves.
place one half in the clear water and the other in the colored water and make sure they are standing securely and will not fall over.
Check on your project every hour to see what is happening
Make meticulous notes and take photos if it is possible, for your display

What happens?

What do you see happening?
Why is it happening?
What is the process called?
What does this prove?

Remember all science fair projects, as this osmosis science fair project, must start with a hypothesis, then you do the project using proper scientific method and then you reach a conclusion that either proves your hypothesis correct or wrong. Whether your osmosis science project hypothesis was wrong or correct is not important. What is important is that you followed proper scientific method and reached a proper conclusion.

Examples Of Science Fair Projects – Alternative Bread Mold Project

Magriet — Fri, 12 Feb 2010 15:21:39 +0000

For really good help with science fair projects you can have at 24 Hour Science Projects e-Book.

In this example science fair project you are going to find out what are the ideal conditions for the growth of molds on bread and what can be done to prevent the growth of mold. Molds are fungi and with bacteria they grow on organic materials and causes (or helps with) decay. So, this is one of our alternative Simple Science Fair Projects a Bread Mold Science Fair Projects

This is one of our examples of science fair projects where adult supervision is needed as heat is going to be used and because of the potential danger of the mold growing.

What you need for your science project:

4 Slices of bread

3 Sealable plastic bags, big enough for your slices of bread to fit in it

A Pair of rubber gloves

Tags to mark your bags with

A knife

Antiseptic cream

A piece of kitchen towel

A small plate

A note book

Camera

How to do your project:

1. We are going to use three different conditions: completely dry bread, normal bread as it is and bread spread with antiseptic cream. Our problem is to find out the conditions that speeds up decay, in this case the mold growing on the bread.

2. Formulate your hypothesis on what you think will happen

3. For your control place a piece of kitchen towel on a plate, place a slice of bread on the plate and place it in a cool dry place. (Why on a piece of paper towel?)

4. Take one of your slices of bread and completely dry it out in the oven at a very low heat.

5. Let it cool down completely. (Later on you should be able to give reason why it has to cool down completely)

6. Place the cold piece of “toast” in one of the plastic bags and mark it with a tag.

7. Place another slice of bread in one of the bags just as it is and mark the bag.

8. Spread your last slice of bread with antiseptic cream on both sides and place it in the last plastic bag and mark it.

9. Now you have to leave them in a warm (not hot) place.

10. Each day you have to make your observations, write it down and take a photo of your experiment. Do not forget your control.

11. Keep this up for a week.

12. You are now ready to write your conclusion, remember to give the reasons for what has happened to your slices of bread. Include your control in your conclusion. Your control shows what happens when you do not do anything, this id how you can draw the correct conclusion about what has happened to your other slices of bread.

* Do you know why the toast had to cool down completely before you placed it in the plastic bag?

* Is there only one reason for what happened to the toast or are there more than one?

* Why did you have to place your control on a piece of kitchen towel?

To get all the answer for doing a top science fair projects I recommend that you Download 24 Hour Science Projects e-Book.

Examples Of Science Fair Projects

Magriet — Fri, 12 Feb 2010 15:16:17 +0000

Getting good examples of science fair projects are not always that easy. It feels as if it has all been done before. Or maybe you have left it too late and now you are desperately searching for a good idea. This is what this post is about.

I’m taking well know examples of science fair projects and giving them a new twist, this should freshen them up a bit! Use them as the start of building your own unique project. If you want to do a really exceptional science fair project, I can strongly recommend 24 Hour Science Projects e-Book! In this e-book you will get all the info you need to do a winning science fair project.

Examples Of Science Fair Projects – Preservation And Decay Examples

These preservation and decay examples of science fair projects are variations of some of the most well know examples of science fair projects with a twist in them. Look at what causes certain things decay faster than others and do the bread mold one a little different.

Caution: Because a knife is used in this experiment adult supervision is needed. It is also necessary that an adult make sure the kids do not handle the rotting fruit and vegetables without their gloves on. Although these examples of science fair projects are easy and all kids can do it, it is best done under adult supervision.

What you need for your “what will decay” project

* 3 Each of a variety of fruit and vegetables such as apples, pears, carrots, potatoes, oranges etc. The more fruit you have the better the picture you’ll get.

* A pair of rubber gloves

* A knife or peeler

* A small piece of plastic

* A stone

* A piece of wood

* A large plastic garden tray with holes in the bottom (big enough to hold all the fruit and vegetables you have)

* An old newspaper

* A bag of compost

* A garden spade

* Pen

* Note book

* Camera

How to do your project:

1. Formulate your problem and formulate your hypothesis before you start with your science experiment.

2. Make very detailed notes of every step of your science project and give the reason for everything you do.

3. For your control, keep one of each kind of your fruit in a dry cool place for the length of your project. Every time you dig up your project make sure to also make notes of what is happening with your control. Take photos to make it easier.

4. Line your garden tray with newspaper and cover it with a layer of compost.

5. Place the piece of plastic, stone and piece of wood in the tray.

6. Peal one each of all your fruit and vegetables, leaving one of each kind unpeeled.

7. Place one peeled and one unpeeled fruit and vegetable in the tray with the other objects.

8. Completely cover them with the compost.

9. Now get an adult to help you dog a shallow hole in the garden in a shady area.

10. Place your tray in the hole and cover it with soil until only the top edge of the tray is visible (so you can dig it up easily later)

11. Buried like this the fruit and vegetables will remain moist.

12. Leave your project for a week.

13. Dig the tray up.

14. Inspect all the fruit and vegetables as well as the plastic, stone and wood.

15. Make detailed notes of what you see.

16. Take photos of your tray with everything on it.

17. Bury your tray again in the same manner.

18. Leave your project for another week and repeat your observations.

19. Keep this up until some of your fruit and vegetables as decayed completely.

20. In dry climates it may be necessary to dampen the soil a little if it gets completely dry. Do not soak it though, simply dampen it a little.

21. Make sure that you make very clear notes about the stages of everything in your tray every time you take it out.

22. You must also make sure that you take enough high quality photos for your display.

23. Now you will be able to write your conclusion and to discuss your findings. Where your hypothesis correct? Remember, whether you were right or wrong is not important, what is important is that you followed the correct scientific method and how you arrived at your conclusion.

* Why did the fruit and vegetables with their skins on decay at a different rate than the peeled ones?

* Why did the plastic and the stone stay the same?

* What happened to your control fruit and vegetables and why?

To do a really good science fair project there are many things to take in to account. You must also make very sure that you follow the correct scientific method.

Getting a good e-book to help you may be a good idea. A good e-book will guide you through all the steps and make very sure that you do not leave something out. Download 24 Hour Science Projects eBook! With this amazing e-book you will get all the help you need.

Science Fair Food Projects – How To Stop Food From Rotting

Magriet — Wed, 22 Apr 2009 15:52:50 +0000

Science Fair Food Projects – How To Stop Food From Rotting

24 Hour Science Projects

This is one example of our easy science fair food projects the kids will enjoy. You will need about two weeks to complete it so, if you have waited until the last minute it may be a good idea to have a look at 24 Hour Science Projects where you will find many you can do in 24 hours or less.

For a good science fair project you have to make notes of all your steps, saying what you are doing and why you are doing it. You must formulate a hypothesis, and do the experiment according to the correct scientific method and think of your display. It is always a good idea to take photos as you go. Once again, if you are unsure, go to 24 Hour Science Projects.

This experiment is going to show us why some substances can be used as preservatives. What is a preservative? In this experiment we are going to look at natural preservatives and not chemicals developed by scientists.

Science fair food projects always have a very practical lesson for the kids to learn and this one is no exception. They will see why some ordinary household food ingredients have been used for centuries to preserve food, especially before refrigerators and freezers where available!

After the project has been completed, let an adult dispose of all the food as it may be rotting. It is also best to let an adult do all the cutting involved.

What you will need for your experiment:

An apple sliced into six equal pieces
6 Small jars
Enough salt to fill a jar
Enough sugar to fill a jar
Enough antibacterial soap to fill a jar
Enough vinegar to fill a jar
Enough water to fill a jar
A felt tipped pen
Some paper plates
Labels to label your jars with
A knife
Disposable utensils to work with the rotting apple pieces (so your hands do not come into contact with them.)

How to do your experiment:

Label the jars as follows: sugar, salt, vinegar, antibacterial soap, water and control.
Do you know what the “control” is for? This goes towards the proper scientific method.
Now you place a piece of apple in each jar.
Remember to take photos of each step for your display
Now you have to completely cover the apple pieces with each substance.
In the jar marked “sugar,” you cover the piece of apple completely with sugar and in the jar marked “salt” you cover the piece of apple completely with salt etc.
In the jar marked “control” you do not cover the piece of apple with anything.
Do you know why you do not cover the piece in the “control” bottle with anything?
Now you have to place the jars in a cool place
After one week your take the jars and examine their contents.
Make detailed notes of all the changes and do not forget to take photos
When you want to look at the pieces in the sugar and salt where you cannot see through the substances, throw them out on a paper plate and use the disposable utensils to dig them out and look at them
Which apple pieces rotted?
Which of the pieces have the appearance that they have been preserved?
Do the preserved pieces appear dried out?
Can you observe any color changes in the pieces of apple?
Can you notice any difference in the texture of the apple pieces?
These are all the things you have think of and make meticulous notes of.
Remember your photos!
Now it is only a case of putting your display together and you will have done one of our fun science fair food projects.

For more Science Fair Food Projects you can have a look at our site Easy Science Fair Projects.

If you have no more time and your project has to be in by tomorrow, best go to 24 Hour Science Projects and get a complete project you can do in 24 hours or less.

Science Fair Projects Kids Will Enjoy Part Seven – Static Electricity

24 Hour Science Projects

Here is part seven of our Science Fair projects Kids Will Enjoy about static Electricity. In this experiment we are going to see how to objects that are negatively laden are attracted to objects that are positively laden. Once the objects are no longer negatively laden, they are not drawn by a positively laden object any more.

Remember for a full science project you will have to combine this whole series, so, I hope you have time to wait for them all! If not, there is a very good solution for you, go to 24 Hour Science Projects; there you will find complete science fair projects you can do in 24 hours or less! So, if you are in a hurry, go to 24 Hour Science Projects now!

Here are our science fair projects kids will enjoy:

Remember, for all science fair projects you have to make notes of everything you do, why you do it, what you are trying to prove or demonstrate and your conclusion. It is always a good idea to take photos for your exhibition.

The case of the dancing paper dolls:

What you need for your experiment:

Two books
A glass disk
A metal plate
Two books
Tissue paper dolls about 3cm tall (cut any way you prefer as long as they not too big)
A woolen cloth

How to do your experiment:

Cut out your paper dolls (about 3-4)
Place two books a little way apart with the metal plate between them
Place the glass disk over them to be over the metal plate
Place the paper dolls in the metal plate
What happens when you place the paper dolls on the metal plate under the glass disk?
Now rub the glass disk with the woolen cloth for a few minutes
What happens?
Why does it happen?

By rubbing the glass disk with the woolen cloth it is loaded with electron to make it negative
Now the disk draws the positively laden paper dolls and they are also loaded
Now they drop down and the metal plate draws the electrons from them, once again making them positive
Now the glass draws them again and so the dance continues

I think this can be quite a good display for your friends to admire!

This is the seventh of our short series of science fair projects kids will enjoy. Look out for the others as doing all these experiments as one will probably be the best way of doing a thorough science fair project.

Science Fair Projects Kids Will Enjoy Part Five – Static Electricity

24 Hour Science Projects

Here is part five of our Science Fair projects Kids Will Enjoy about static Electricity. In this experiment we are going to see how to objects that are negatively laden “push” each other away. Opposite to a negative and positive drawing each other.

Here are our science fair projects kids will enjoy:

The case of the hostile balloons!

What you will need:

2 Balloons
2 pieces of string
A wooly sweater

How to do this experiment:

Blow up both balloons as much as possible without bursting them
Tie them with the strings
Rub both on your sweater for a few minutes
What happens?
Why do you think it happens?
What happens to the balloon closest to your sweater?

After you have rubbed the balloons on your sweater, they are both negatively laden with electrons they withdrew from your sweater. Because the sweater has given off the electrons it is now positively laden, this is why the balloon closest to your sweater sticks to your sweater while the two balloons drift far apart. So, what does that tell you about two objects that are negative or positively laden?

This is the fifth of our short series of science fair projects kids will enjoy. Look out for our next post as doing all these experiments as one will probably be the best way of doing a thorough science fair project.

Science Fair Projects Kids Will Enjoy Part Four – Static Electricity

24 Hour Science Projects

Here is the next project in our series of science fair projects kids will enjoy. In this project kids will see why the effect of static electricity takes of in humid conditions. Here we are going to use a plastic spoon to “bend” a very thin stream of water.

Remember for a full science project you will have to combine this whole series, so, I hope you have time to wait for them all! If not, there is a very good solution for you, go to 24 Hour Science Projects; there you will find complete science fair projects you can do in 24 hours or less! So, if you are in a hurry, go to 24 Hour Science Projects now!

Here are our science fair projects kids will enjoy:

The case of the water “bend!”

What you will need for this experiment:

A plastic spoon
A wooly sweater
Access to a reliable tap where you can turn it on to make a really small little stream of water

How to do this project:

Rub the spoon against the wooly sweater for a few minutes
Open the tap so it makes the smallest stream possible
Bring the spoon close to the water stream
What happens?
Why do you think it happens?
Read the explanation about static electricity in the first of this series on static electricity.

At first the electrically laden plastic spoon draws the water. Should the spoon touch the water, the experiment is over as water is a good conductor of electricity and will immediately draw the electricity from the spoon and the spoon will not be charged any more. Therefore it will stop “bending” the water. This is why experiments on static electricity works better on dry days than on days that are very humid.

This is the fourth of our short series of science fair projects kids will enjoy. Look out for our next post as doing all these experiments as one will probably be the best way of doing a thorough science fair project.

Here are our science fair projects kids will enjoy:

The case of the dancing snake

What you need for this experiment:

A piece of tissue paper about 4 inches by 4 inches
A pair of scissors
A pen
A wooly sweater
A lid of a tin, big enough for your snake to fit on

How to do this experiment:

Cut a spiral formed “snake” our of the tissue paper
Place it on your lid
Bend the head of your “snake” so it is upward
Rub your pen on the wooly sweater for a few minutes
Hold it an inch or so above the snake
What happens?
Why do you think it happens?
Try and explain it after reading the explanation in the first experiment in this series on this blog
Why do you think we placed it on the tine lid?
Does it play any role in the “snake dance?”

The clue here is that when you hold the electrically charged pen close to the snake which is uncharged it is drawn to the pen and lifts up toward the pen. The moment the electrons pass to the snake, the tin lid absorbs it and the snake is once again uncharged. That is why it keeps on lifting again and again.

This is the third of our short series of science fair projects kids will enjoy. Look out for our next post as doing all these experiments as one will probably be the best way of doing a thorough science fair project.

Science Fair Projects Kids Will Enjoy Part Two – Static Electricity

Here is the next project in our series of science fair projects kids will enjoy. In this one we are going to try and separate finely ground pepper from salt! It is so important for kids to enjoy science that it is always good to do fun science experiments with them.

For a good science fair project you have to make notes of all your steps, saying what you are doing and why you are doing it. You must formulate a hypothesis, sdo the experiment according to the correct scientific method and think of your display. It is always a good idea to take photos as you go.

The case of the pepper and the salt:

What you need:

Very fine pepper
Salt
A plastic spoon
A woolly sweater

What you have to do:

Sprinkle quite a bit of the pepper and salt on the table
Make sure you mix them well
Rub the plastic spoon on the sweater for a few minutes
Hold it above the mixture on the table, not too low but high enough for the pepper to attach to it
What happens?
What did you do when you rubbed the spoon on the sweater?
Have a look at the explanation in our previous post called “Science Fair Projects Kids Will Enjoy Part One – Static Electricity”

You must make sure the spoon is high enough, if it is not high enough the salt, that is heavier than the pepper, will also be able to jump as high as the pepper and the two will not separate.

Science Fair Projects Kids Will Enjoy Part One – Static Electricity

All kids love the fun you can have with static electricity. This is why this is one of our science fair projects kids will really enjoy doing. This is a series of short experiments showing static electricity in action. The kids will be able to do most of it alone and all the supplies are readily available.

Here are our science fair projects kids will enjoy:

The case of the clinging balloons:

What you will need:

A few balloons
A woolly sweater

This is what you have to do:

Blow up your balloons and tie them securely
Rub the balloons against your sweater for a few minutes
Now press them against the ceiling
What happens?
What did you do when you rubbed the balloons against your sweater?
How does that make the balloons cling to the ceiling?
Make note of how long they stay there
Do you think there are factors that can make them fall down sooner or hang there for a longer period?
Try boiling a kettle in the room and see what happens (let an adult help here!)

By rubbing the balloons against your sweater you are charging the balloons with electricity. How? They absorb small particles called electrons, which are negative electrical particles, from the sweater.

Because objects that are electrically charged draws objects that are not electrically charged, the balloons “stick” to the ceiling until they are no longer electrically charged.

Normally the balloons will stay there for a long time as the ceiling is a very weak conductor and the electrons flow very slowly through the ceiling because a room is normally very dry. If you room is a little more humid, it will take longer. It may be a good idea to do two experiments, one in dry air and one in humidity and see if your results differ.

This is the first of our short series of science fair projects kids will enjoy. Look our for our nest post as doing all these experiments as one will probably be the best way of doing a thorough science fair project.
