Easter Egg Rockets
Thrust: a force or push. When a system pushes mass in one direction, there is a thrust just as large in the opposite direction.
Rocket: devices that produce the force, or push, needed to move an object forward.
Chemical reaction: the combination of two reactants to form an entirely new product (ie Alka Seltzer contains baking soda and citric acid, when they get wet they mix, release carbon dioxide and make sodium acetate.)

By participating in this program, children will create a rocket that uses a chemical reaction to create thrust, demonstrating Newton's second and third laws.

Prep Time in Minutes
If your plastic eggs have holes in them, fill the holes with hot glue. Separate the two halves of the eggs.
Children will fill out the data table to track their variables and measurements.
Position yourself or your tube so your egg rocket is launching from the same place each time.
Put 1-2 tablespoons of water in one half of the egg and place it in the cardboard tube.
Drop half of one Alka Seltzer tab in the water and QUICKLY seal the other half of the egg on top.
Pressure will build until the top of the egg flys off.
Measure how far the top of your egg goes. Record your data in the chart and repeat the experiment with different amounts of Alka Seltzer.
