We tested the effectiveness of washing up liquid on fatty milk and tried and created our own optical illusions 'Bird in a cage'
We also had a workshop with Anne from Sam's Simple Science.
We created our own mixed colour patterns on cloth using pens and a special liquid to help it spread. We created our own layered liquid bottles and had excellent fun making our own elephant toothpaste!
We had a terrific day and asked lots of interesting and exciting questions.
An award for the most inquisitive scientist went to a child in every year group. Our awards went to Harrison in year 1 and Jamie in year 2.
Here are some photos of our excellent day.
Here we were testing the effectiveness of washing up liquid on milk. We had a tray of milk then used syringes to drop little droplets of food colouring in the milk. We then used pippets to drop in washing up liquid - the washing up liquid pushed the food colouring around the milk to
try and 'wash' it away.
It didn't work well with double cream.
Next, we used cloth and pens to create beautiful colour patterns. We used the pens and drew a dotted circle in the middle of our cloth. We then dropped in tiny amounts of special liquid to make the pen marks spread. Here are some of our beautiful patterns.
We then used household liquids to create a layered bottle. You have to layer them in a specific order for it to work! We tried to guess the liquids first but some of them were tricky.
Our last experiment with Anne was creating elephant toothpaste! Its created when a chemical reaction happens between liquids.
We were very excited!!
