5 fun science experiments you can do at home

British Science Week is a ten-day celebration of science, technology, engineering and maths, featuring entertaining and engaging events and science experiment activities across the UK for people of all ages. The theme this year is all about growth. To celebrate, we put together 5 fun science experiments you can do at home:

Play Foam clouds

This is a fabulous science experiment for learning about the weather, and so easy to do at home!

You will need:

  • A glass
  • Pipettes
  • Play foam
  • Blue food coloring
  • 1 cup Water

Fill a glass halfway with water. Top the glass up with play foam to look like clouds. While the foam is setting, add about 10 drops of blue food colouring to a small container, and top up with water. Use a pipette to suck up the coloured water, and pour it over the play foam. Watch as the blue colouring travels through the foam clouds and looks like rain in the glass!

Multicoloured Flowers

This science experiment is all about learning how capillary action works, and how flowers grow.

You will need:

  • White flowers such as carnations
  • Food dye in at least 3 different colours
  • Glass jars
  • Water

Fill each glass jar about 3/4 full with water. Add 10-20 drops of one colour in to each jar. Place one white flower in each jar, put them in a sunny place, and wait!

In about 3 days you should see the flowers begin to change colour. Monitor the flowers daily to track their progress!

Cress Heads

We couldn’t get through British Science Week without thinking of one of our favourite plant growth science experiments, cress heads!

You will need:

  • Containers such as plant pots, egg shells, or empty yoghurt pots
  • Cress seeds
  • Soil
  • Paper towels
  • Cotton wool
  • Water

Fill one container half way with soil, add some cress seeds, and top up with soil. Fill another half way with damp cotton wool, and add some cress seeds on top. Finally, fill another half way with damp paper towels, and add some cress seeds on top.

Monitor the cress growth using a cress diary.

For an extra fun science experiment, draw faces on the containers and watch the cress become the hair of the characters!

Baking Soda Volcano

This one could be messy!

You will need:

  • Clay
  • Paint
  • Plastic bottle or glass jam jar
  • 5 tbsp Baking soda
  • 1 cup Vinegar
  • 1 tsp Dish soap
  • Food dye

Add a few drops of food dye to the bottle, followed by the dish soap, then the baking soda. Mix all together until you get the desired colour.

Use the clay to create a volcano structure around a plastic bottle. Once the clay is dry, paint and decorate how you like!

Put the volcano in a place where you don’t mind mess, such as outside, add the cup of vinegar and watch the volcano erupt!

Glitter germ experiment

This is an experiment which became popular in the last two years as we taught children about the importance about washing their hands. Simple, yet effective!

You will need:

  • A shallow dish
  • Water
  • Glitter
  • Liquid hand Soap

Pour water into the shallow dish, then add glitter. Try putting your finger in the glittery water, and notice that the glitter remains in place. Then, try adding some soap to your fingers, and once more put your finger in the glittery water. Watch as the glitter quickly moves away!

We hope you enjoyed learning about these simple science experiments! We love seeing your creations, don’t forget to tag us on social media!
