Easy Science Experiments for Primary School Students

Science experiments are the most fun when they are easy, require minimal adult assistance, and can be done without many supplies. Check out the following easy science experiments that may leave you stunned with their outcomes.

What makes a great penny cleaner?

We’ve most often heard taco sauce makes a great cleaning agent for old pennies. Is that true? Let’s find out what makes the bets penny cleaner.

Process

  • Place three coins on three plates.
  • Cover each penny with each of these mixtures: tomato paste + vinegar, salt + vinegar, and tomato paste + salt. Let the mix sit on the coins for five minutes.
  • Rinse the pennies under running water and you can find out who’s the clear winner! Is it the mix of vinegar and salt?

How hard and sturdy are egg shells?

We’ve often observed egg shells cracking even when touched lightly. Conduct this easy science experiment to find out how fragile or hard egg shells really are.

Process

  • Spread a sheet of plastic before doing the experiment because it may turn messy; a couple of eggs are bound to crack!
  • Place two cartons of eggs next to each other. Make sure all the eggs are kept round side up (not the pointy side up) and there are no breaks or fractures in any of the eggshells. Replace the defective ones before you begin the experiment.
  • Remove your socks and shoes. Hold on to a friend and try to step up onto the first carton of eggs with a foot. The trick is to make your foot as flat as possible so that your weight is evenly distributed across the tops of the eggs.
  • When you’ve positioned your foot well, try to shift all your weight on the egg-leg and slowly bring on your other foot on the other carton of eggs. Don’t fret if you hear cracking sounds from the egg cartons. Instead concentrate on balancing on the cartons.
  • So aren’t egg shells stronger than we imagine?

What happens when vinegar and baking soda mix?

Vinegar and baking soda are two commonly used ingredients in the kitchen. What happens when the two are mixed? Let’s find out.

Process

  • Fill up a bottle till half with vinegar.
  • Fold two tablespoons of baking soda in a tissue paper and dump it into the bottle. They key is to put all the baking soda together into the vinegar at a time. You can explore the idea of using a funnel to pour the baking soda too into the vinegar.
  • Stand back and watch what happens! Do you notice an erupting volcano? Baking soda and vinegar, two very easily available ingredients, reacted to form the volcano.
