School is out and it is time for summer vacation! During these summer months, you may find yourself at home more often with your children. If your child struggles with science, summer vacation can be a great time for him to develop renewed curiosity and interest in the subject. Use this time to make science fun with your children. Everyone is familiar with the baking soda and vinegar volcano, why not try out a new experiment at home?
Make a simple Cartesian Diver that will float or sink on command. All you will need for this experiment is 1 ketchup packet from a restaurant, water, and a clean, clear 1 or 2 liter bottle. Check your ketchup packets buoyancy by placing it in a bowl of water to see if it will float. You need a packed that just barely floats in the water.
Take the ketchup packet and put it in the plastic bottle. Fill the bottle to the very top with water and put the cap on tight. Squeeze the sides of the bottle and watch the ketchup packed sink. The packet has a small bubble of air trapped inside of it. As you squeeze the bottle, the pressure inside the plastic bottle increases. The increase in pressure compresses the air inside the packet which changes the density of the packet causing it to sink. When you let the bottle go, the packet goes back to the top. You can even try squeezing the bottle just enough to keep the diver suspending in the middle of the bottle.
