Kids love experiments so what better over the school holidays than these STEM experiment kits by Thames and Kosmos?
We were sent two kits, Bouncing Planets and Molecule Beads but there is a wider range.
Our kits were both really easy (but not too easy) and require minimal adult supervision for kids of 8 years and over.
Here are our creations:
The first experiment kit from Thames and Kosmos, Bouncing Planets:
“Using granulated material and water you can make your own bouncy balls in various colours”
Put the two sides of the mold together and pour in your choice of coloured granules, layering different colours gives different results
Fill the beaker with warm water and immerse the now filled sphere into it so water covers the top. Give it a little wiggle so water penetrates.
Leave the mold in the water for two minutes
After two minutes remove the mold and leave to dry for a further 3 minutes
After 3 minutes prise apart the two side of the sphere to reveal your bouncing Planet.
Experiment two is to make Saturn’s ring – we didn’t leave it long enough and made a hash of the first one! Hopefully this one will work better. You sprinkle a ring of granules on the dish and then drop water using the pipette. You leave it for a few hours then carefully peel away.
Onto our second experiment kit, Molecule Beads from Thames and Kosmos:
“Whether is be balls, snakes or jellyfish – using this experimentation kit, you can form and study all kinds of slimy giant molecules. Become a slime master and carry out fun experiments”
This is a very easy experiment and there is no waiting time.
First of all you dissolve the sachet of Calcium Lactate into the beaker of water
Using the spatula provided you stir until the granules dissolve
The first experiment is to drop individual drops of coloured alginate liquid into the solution to make little balls. You can scoop them out of the water using the spoon and examine them.
The second experiment is to pour lines of the coloured alginate liquid into the solution.
Remove the coloured strings to examine the strings. Is there an air bubble. Can you cut the string with scissors? Is there water inside?
What did we think of the Thames and Kosmos experiment kits?
We thought they were great fun. Not too messy (I’m not a fan of cleaning up) and easy enough for older kids to do almost by themselves.
There is minimal waiting time too which is good for impatient people (like me!). They don’t take too long to complete either, so good for short attention spans…
Our favourite were the bouncing planets:
