In Junior Infants we had great fun during Science week. Here are a few of the experiments we tried out:
Experiment 1: Floating and Sinking
- First we predicted which objects would float or sink when placed in water.
- Then we tested them out in water to see if our prediction was correct.
Results: Some objects had air inside them and we learned that the air inside was lighter than the water and that’s why they floated.
Experiment 2: Skittle colour mixing
- We placed the skittles around the edge of a plate in a circle shape.
- We poured warm water into the middle of the plate until it reached the sweets.
- We watched the colours mix.
Result: The outside of the skittles are made of sugar. When sugar is put into warm water it dissolves. As the colours meet, they mix creating different colours.
Experiment 3: Paper Towel colour mixing
- First we put yellow, blue and red food colouring into four separate cups.
- Then we added water to each cup.
- We used sheets of kitchen towel, folded them and placed one end in one cup and the other end into the other cup.
- We then watched what happened.
Result: The water moved up the paper towel because the paper is absorbent. The colour travels with the water, making the kitchen towel change colour from white to red, blue, or yellow. The colours mix when they meet together. Red and blue make purple and blue and yellow make green.
Beebots:
We had great fun learning how to use the Beebots. We had to key in instructions to make the Beebot move forward, backwards, right, left or turn around.
- We made a maze and directed the Beebots from one side to the other.
- We used the shape board to direct the Beebots to different shape colours and sizes.
- We used the number ladder to move the Beebots to the different numbers.
We hope you enjoy our experiments.
