Room 12 dived into three simple yet fascinating experiments that reveal the magic of change in everyday materials.
Pepper Scatter Showdown- Unveiling Surface Tension
Pepper Scatter Showdown.
This experiment demonstrates the concept of surface tension in a visually captivating way.
you will need
-
shallow dish of water,
-
some ground pepper,
-
drop of dish soap.
Sprinkle the pepper evenly across the water's surface and watch as it floats. Touch the surface with a soapy finger and observe the pepper race to the edges.
This happens because the soap disrupts the surface tension, showing how molecules interact at the surface. This experiment helps students understand the invisible forces at play on the surface of liquids and how they can be altered.
The pepper experiment was cool because it was fun to learn how things work by doing it myself, like when the pepper moved away from my finger.
When I add the soap, it makes the pepper move away and form a half circle.
The Milk Disco Dance Party
food colouring dance.
You will need
-
A saucer with milk.
-
dishwashing liquid
-
food colouring
The children observed how the food colour moved away from the dishwashing liquid, creating patterns that reminded them of rainbows. Through this hands-on experiment, students learnt about surface tension and how the dishwashing liquid breaks down the fat molecules in milk, causing the colours to move.
They made thoughtful observations about how different colors mixed together and how the movement slowed down over time. Many students excitedly described it as magical experiments .
I learned about the reaction between food colouring, dishwashing liquid, and milk.
I learned how mixing food colouring and dishwashing liquid with milk can create a colourful reaction, making the milk look like a rainbow.
Gummy Bear Growth Spurt: The Osmosis Adventure
Osmosis with the Gummy Bear Growth Spurt experiment.
You will need
-
gummy bears
-
vinegar solution
-
salt solution
-
sugar solution
Place the solutions on the gummy bears. Observe the gummy bear in the sugar solution has significantly grown and the gummy bears in the vinegar solution have shrunk.
is due to osmosis, where water moves from an area of low solute concentration (the water) to high solute concentration (inside the gummy bear) through a semipermeable membrane (the outside of the gummy bear).
My favourite experiment is the gummy bear one because the gummies change in different solutions, and I have done it at home too.
I tried putting a gummy bear in vinegar, and it broke. I thought we were going to eat the gummy bears.
Gummy bear experiment was my favourite experiment because they looked colourful, and the ones in vinegar had cracks.
I learned about how gummy bears can change colour and size during the experiment. They observed that some of the gummy bears got really big.
