Hooked on Science - Clean Notebook Spring Launcher (07/15/2019 - 07/21/2019)

INGREDIENTS

• Plastic Spiral Notebook

• Dowel Rod

• Ruler

INSTRUCTIONS

STEP 1: Remove the paper from the plastic spiral notebook spring.

STEP 2: Hold the dowel rod by placing your thumb and index finger at one end of the dowel rod. Slide the plastic spiral notebook spring onto the other end of the dowel rod.

STEP 3: Using your hand, barely compress the plastic spiral notebook spring against your thumb and index finger. Release the plastic spiral notebook spring and observe. Using the ruler, determine how far the plastic spiral notebook spring launched. Use this evidence to construct an explanation relating the speed of the plastic spiral notebook spring to the energy of the plastic spiral notebook spring.

STEP 4: Using your hand, completely compress the plastic spiral notebook spring against your thumb and index finger. Release the plastic spiral notebook spring and observe. Using the ruler, determine how far the plastic spiral notebook spring launched. Use this evidence to construct an explanation relating the speed of the plastic spiral notebook spring to the energy of the plastic spiral notebook spring. Compare the effects of the different directions of the pushes and pulls on the motion of the plastic spiral notebook spring. Provide evidence that a pattern can be used to predict future motion of the plastic spiral notebook spring.

EXPLANATION

When the plastic spiral notebook spring is compressed, energy is stored. Potential energy is stored energy. When the compressed spiral notebook spring is released, potential energy is transformed or changed to kinetic energy, and launches across the room. Kinetic energy is energy of motion.

SCIENCE SAFETY

PLEASE follow these safety precautions when doing any science experiment.

• ALWAYS have an adult present.

• ALWAYS wear the correct safety gear while doing any experiment.

• NEVER eat or drink anything when performing any experiment.

• REMEMBER experiments may require marbles, small balls, balloons, and other small parts. Those objects could become a CHOKING HAZARD. Adults are to perform those experiments using these objects. Any child can choke or suffocate on uninflated or broken balloons. Keep uninflated or broken balloons away from children.
