Easy Elementary Science Projects - Physical Changes Science Projects

Doing easy elementary science projects with the kids can be fun and it does not only have to be done for science fairs. Kids love learning in a fun “Play” way and we can use easy elementary science projects to teach them about the wonders of science without them actually realizing that they are learning. Doing easy elementary science projects with the kids is also a great way for homeschoolers to teach the kids science. I think we must start doing a lot more “little” projects with the kids. Here are a few short fun ones to do with the kids.

Physical changes easy elementary science projects

Physical changes can happen when two substances interact or when energy is applied to one or

more of the substances. In this easy elementary science projects we are going to see how substances change and then we are going to reverse the physical changes.

The salt solution physical change experiment

What you need for this science project:

• Salt
• A measuring cup
• A teaspoon
• A heatproof glass or container
• Water

How to do this easy elementary science experiment:

1. Pour ½ cup of warm water into your glass or container
2. Dissolve 2 teaspoons of the salt into the warm water
3. What happens now? The salt becomes invisible, this is a physical change.
4. Now place the glass in a warm place and leave it for a few days until all the water has evaporated.
5. Observe what has happened. The water evaporated and the salt was left behind in the glass.
6. Once again a physical change took place. The salt is now visible once again.

The rock candy physical change experiment

In this easy elementary science project we are going to do more or less the same with a sugar solution.

What you need for this science experiment:

• A small heatproof container such as a beaker
• A piece of string long enough to hang to the bottom of the beaker
• ½ Cup of hot water
• 1 Cup of sugar
• A pencil

How to do this experiment:

1. Dissolve the sugar in the water in your beaker
2. Once again observe the physical change
3. Tie the string around your pencil and place the pencil over the top of the beaker so the string dangles in the water.
4. Leave your beaker in a hot dry place for a few days and observe what happens.
5. Sugar crystals start forming on the string, a physical change again.
6. There you have your rock candy!

A salty work of art easy elementary science project

In this experiment we are going to have fun. This experiment can double up as an easy kids craft as you will be making a lovely painting.

In this experiment we are going to show how salt and food coloring dissolves in water and reverts back when the water evaporates. You will be amazed at the beautiful painting you will end up with. This experiment needs a little more preparation, but is well worth the trouble.

What you need for this experiment cum craft:

• As many containers as colors you intend to use
• Warm water
• As many colors food coloring as you want to use
• Lots of salt
• Thick paper
• Paint brushes

How to do this experiment:

1. First you have to mix salt into your warm water until it will hold no more salt (it is called a saturated solution)
2. Now divide this salt solution into your containers.
3. Add the food coloring to the water. Make it strong so the colors will come out really well.
4. Using your paint brushes make a painting on your paper. Put it on thick so that there is really lots of salt and coloring.
5. Leave your painting in a warm dry place until all the water has evaporated.
   Now you can observe the salt crystals and the food coloring that remains behind after the water has evaporated.
6. A Physical change again, reversing the first one.
7. Observe the beautiful patterns the food coloring makes around the salt crystals.
8. Now you have a beautiful work of art as well as a science experiment.

I hope the kids will enjoy these easy elementary science projects and really have a fun learning experience.

In our previous good science fair project we had a look at chlorophyll and how plants use this chlorophyll, sunlight, water and carbon dioxide to produce glucose (a form of sugar.) What else, that is very important, is produced through photosynthesis? (In the process carbon dioxide is taken from the air, what is released back into the air?) Now we are going to do a good science fair project to demonstrate how plants actually reach for sunlight. We know by now that they cannot survive without light, which we proved in our previous science fair project. Now we are going to do a really fun science fair project. If you want to do a really good science fair project, it might be a good idea to combine these two science fair projects as it gives you a very clear and visual picture of plants growing and needing sunlight.

Today’s science fair project is a good science fair project for someone that is a little handy. We are going to make a maze in a shoe box to demonstrate how the plant searches and reaches for light.

What you will need for your good science fair project:

* First you need a shoe box
* You will need a pair of scissors
* Stiff card
* Some sticky tape
* Black paint
* A paint brush
* A pair of gardening gloves to protect your hands
* A runner bean
* A plant pot
* Some good compost
* Water

Now for the fun part: making your maze in your shoe box!

1. To start cut a hole in the one end of the shoe box.
2. Making a maze in your shoe box is very easy, start by cutting eight flaps out of the stiff cards. The flaps must fit securely into your shoe box in the width.
3. Now paint your shoe box and the eight flaps all over with black paint. Do you know why we are doing that? Think about the light reflecting…yes, the black paint is to stop the light entering through the hole from reflecting inside the shoe box!
4. Now you can make a maze by sticking the eight flaps of card inside the shoe box with sticky tape. Cut slots into your flaps at a different place in each flap to form a maze (if you are not sure how to do this, ask for the help of an adult who knows what a maze looks like.)
5. Plant a runner bean in a small plant pot with compost.
6. Water the soil each day to keep it moist but, do not make it too wet. Keep it in a warm place until the bean has a shoot. Remember to keep the soil moist, depending on the temperature; it may not be necessary to water the bean everyday.
7. When your plant has a shoot place it at the bottom of your maze.
8. Close the lid and place the maze in a sunny spot.
9. Remove the lid once a day to see if your plant needs water.
10. Now you can observe what is happening.
11. If you did it right, the plant will grow and find its way through your maze to steadily move towards the light.
12. Eventually your plant will poke through the hole at the top of your shoe box.
13. For display purposes it is a good idea to take a photo of your plant growing zig-zag through your maze and out the hole at the top.

This is one of our good science fair projects for those that like to make things and our prospective gardeners!
