Fun Projects For Science Fair, Easy And Simple

Updated on March 26, 2012

Science Fair, Easy Experiments For Kids - Pollution, Pollution And Once More Pollution

Do an experiment with your kid for Science Fair, Easy and simple, yet lots of fun. I think it is very important for parents to enjoy the experience of the science fair, easy experiments to do with the kids make it possible. Help your kids get exited about science and you will give them a big advantage in life. Even if kids do not want to make science their profession, learning them to think and have enquiring minds will help them with all their studies!

These two following easy science fair projects will make the kids aware of all the pollution issues world wide. This will show them how important it is to prevent any further pollution.

Science Fair, Easy Experiments On Pollution

With this easy science fair project we are going to show the effect of pollutants in the water on the growth of plants and the serious consequences it can have for animals as well. We are going to do an easy science fair project by adding pollutants to water with growing algae and having a look at the results of our experiment. To the water we are going to add detergent, oil and vinegar.

Supplies for this project:

  • Pond soil
  • Pond water with algae
  • Plant fertilizer (liquid)
  • 4 Small jars without lids
  • Water
  • Jug
  • Liquid detergent
  • Old motor oil
  • Vinegar
  • Felt-tipped marker
  • Camera
  • Notebook

What you have to do:

  1. First of all before you start you must write down your hypothesis, that is what you think will happen, and why you think it will happen.
  2. Fill the jug with water
  3. Let it stand for a few days so that the chlorine can dissipate
  4. Label your jars 1, 2, 3 and 4
  5. Jar 4 will be your control, which is the part of your experiment that shows what happens if nothing has been done to the water.
  6. Fill each jar halfway full with your dissipated water
  7. Add ½ inch layer of the pond soil
  8. Add 1 teaspoon liquid fertilizer
  9. Let the jars stand in a sunny place such as a windowsill for two weeks
  10. Make a note of the appearance of the water in the jars
  11. Take a photo of the jars for your display
  12. To jar 1 you now add 2 tablespoons of liquid detergent
  13. To jar 2 you add enough oil to make a layer covering the surface
  14. Now you allow the jars to sit for 4 weeks
  15. To jar 3 you add ½ cup vinegar
  16. Jar 4 you leave as it is
  17. All through the 4 weeks make notes of what is happening and take photos for your display
  18. After the 4 weeks once again make notes and take photos
  19. What has happened?
  20. Why do you think it happened?
  21. What is the appearance of jar no. 4 that is your control jar?
  22. In which jar did the most change take place?
  23. In which jar did the least change take place?
  24. Why do you think this is bad for animals as well as plants?
  25. Explain how each of the above can happen in daily life (what are the kinds of things that cause these kinds of pollution?)

This experiment for Science Fair, easy and very simply shows us the damage we do to our ecosystem by our thoughtless actions. We can all change our habits and do our bit for nature; it is not only the big factories and businesses that are the culprits!

Experiment For Science Fair, Easy Air Pollution Indicators

In our next experiment for science fair, easy ways to have a look at air pollution will demonstrated. Easy Science Fair Projects must not only be for the science fair, but it must also serve to raise our awareness of what is going on around us and how we can do our bit.

This is a longer term project and you will need a few months to complete it successfully.

What you need for your project:

  • 6 Index cards
  • Masking tape
  • Petroleum jelly
  • Camera
  • A notebook
  • Felt-tipped pen

How to do this project:

  1. Start with 3 of your index cards and smear a thin layer of petroleum jelly on it.
  2. Mark the cards a, b and c.
  3. Tape card "a" inside your house, on a wall or something in your room for instance, as your control. (What is that again?)
  4. Tape the other two (card b and card c) onto surfaces outside. If you life close to a busy road, on your postbox would be a good place. Choose a different location for the other one.
  5. Now you have to check your cards everyday for at least a month.
  6. Make a note of the amount of particulate matter (dust, odd bits and pieces of material, pollen and other small particles that float in the air) that gathered on each card.
  7. Take a photo for your display
  8. Repeat this experiment with cards marked d, e and f during the next month.
  9. What happened?
  10. Of what is it an indication?
  11. On which card were the most particulate matter collected?
  12. Can you explain it?
  13. What happened to the cards taped inside your house?
  14. Was it completely clean?
  15. Was it cleaner than the ones outside?
  16. Why do you think the inside one was not completely clean?

This experiment for a science fair, easy and in a simple way shows us what we are breathing every day. Frightening is it not? What do you think can be done about it? This easy science fair project shows us the practical value of science fairs. It raises the students' awareness of what is going on around them and can help them develop into responsible citizens.

      To be honest I think the kid's interest is a better indication. The level can be altered by the detail of the Science Fair project. That being said, I do not think a kid younger than grade seven will really do it justice.

      The water pollution project seems like a great idea, but can you tell me around what grade level it is for? Thank you.

      Hello Koko, if you go to the 24 hour science projects I recommend in this Hub, they have projects that can be done in a very short time.
