Leave a reply
The resources needed for this activity are: 1 egg, a glass and vinegar.

Step 1: Place the egg inside the glass gently.
Step 2: Pour the vinegar inside the glass until the egg is covered and sinked.
Step 3: Wait 24 hours. Throughout such hours, you can see that the egg shell is starting to disappear.
Step 4: After 24 hours, rinse the egg. You could see that the egg no longer has a shell. The shell also becomes bouncy which one can also play with.

Pepper Experiment

Leave a reply

This experiment includes water, food colouring (optional), (soap) and pepper. First, we filled the plate with water and added food colouring. The children then had to put the pepper by themselves into the water. We then added the soap and watched the pepper scatter outwards. The children understood the concept of floating as well as that some objects repell from one another. More importantly the children learnt to be independent by putting their own pepper!
