KENTUCKY (04/15/2019) Pumped up Peeps 2019.


• Peeps
• Vacuum Pumper and Chamber


STEP 1: Place a few peeps inside the chamber. Describe and classify the peeps by their observable properties.
STEP 2: Attach the vacuum pumper to the chamber, remove as much air from the chamber as possible, and observe. Describe and classify the peeps by their observable properties.
STEP 3: Allow the air back inside the chamber and observe. Describe and classify the peeps by their observable properties.


The vacuum pumper removes all of the air from around the peeps, allowing the air inside the peeps to escape. As this happens, the peeps expand. Since the vacuum pumper removed most of the air from inside the peeps, when the air is returned to the chamber, the peeps shrink.


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 while doing 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.
