Document Summary

In this forum, you will share an outdoor science activity that can be used as a resource in teaching. Please do not attach your submission - post it as a discussion post! Your submission must include: the title & creator of activity (your name if you thought it up!) Learning goal: the students will learn about the relationship between thrust and gravity in a rocket. Procedure: cut the valve from the inner tube and discard the inner tube. Using scissors or a craft knife, remove as much rubber from the base of the valve as possible. Using the rag or glove to protect your fingers, push the valve into the hole in the rubber stopper. It should be in the stopper very snugly. Set aside: cut a 5 cm long piece of drinking straw. Tape it to the bottle near the bottom, in line with the vertical axis of the bottle. Trial 1 250 ml of water.
