- Complete Physics Science Kit – Includes vacuum pump and coin-and-feather experiment apparatus to demonstrate gravity, air pressure, and Newton’s laws of motion in a vacuum chamber environment.
- Gravity Demonstration for Classrooms – Ideal for STEM classroom kits, homeschool science lessons, and lab instruction, showing how objects of different mass fall at the same rate in a vacuum.
- Educational Vacuum Pump – Hand-operated pump displaces up to 725 ml of air at 15 ml per stroke; features built-in pressure gauge (cm/in) and release valves for use in air pressure experiments.
- Interactive Coin and Feather Experiment – Demonstrates how removing air with the vacuum pump eliminates resistance, allowing the coin and feather to fall simultaneously—highlighting core physics and gravity concepts.
- Instructional and Homeschool Ready – Step-by-step guide included for setup; suitable for science lab equipment collections in schools or home-based physics and STEM instruction.
This physics science kit includes a hand-operated vacuum pump and a coin-and-feather apparatus for demonstrating gravity, air pressure, and Newton’s laws of motion. Designed for STEM classroom instruction, homeschool science activities, and science lab experiments, it offers a hands-on way to explore core physical science concepts. The coin-and-feather experiment uses a sealed plastic cylinder with rubber stoppers and a hose port for air evacuation. When connected to the vacuum pump, air is removed, allowing the coin and feather to fall at the same rate—demonstrating that in a vacuum chamber, mass does not affect free fall. The vacuum pump features a pumping rate of 15 ml per stroke and can displace up to 725 ml of air. It includes a built-in pressure gauge (in cm and inches) and release valves for safe use. It also works with other science lab equipment such as the #4400 Filtering Kit. An instruction sheet is included, making this an ideal educational science tool for physics demonstrations, air pressure experiments, and physical science activities across learning environments.
