Let's learn about expansion!
Do the following experiments at home with the help of an adult!
Materials: saucepan filled with hot water, oven mitts or gloves, empty glass bottle (such as a ketchup bottle), rock or a weight to hold the bottle down, balloon
Put a balloon over the top of an empty ketchup bottle (you may need to put a rock in the bottom of the bottle for weight). Place the bottle in a saucepan of hot water.
After doing this experiment, posts your pictures here to share them with your classmates and also share your observations and why do you think this happened!
