Poked a pencil through a bag full of water

Science

• The child learned about the concept of pressure as the pencil punctured the bag, causing water to leak out.
• They observed the properties of water, such as its ability to flow and take the shape of its container.
• They gained an understanding of the concept of density as the water inside the bag remained intact despite the hole.
• The activity also provided an opportunity to discuss the states of matter and the differences between solids, liquids, and gases.

For continued development, encourage the child to explore other experiments related to pressure and water. They could investigate different ways to create pressure, such as using syringes or air pumps. Additionally, they could explore the effects of different types of liquids on pressure and observe how they behave when punctured.
