Osmosis Science Project
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
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 Projects Kids Will Enjoy Part Seven – Static Electricity
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.
