Hands on STEM May 2022
Are you ready to get your hands on STEM? This virtual STEM event empowers the next generation of solution seekers with skills they need to take on some of the planet’s greatest environmental challenges.
Join hosts Brandon Okpalobi and Mehaa Raja as they introduced students to a local or global issue, explored why it is happened, connected with inspiring people working to find solutions, and helped students uncover their own potential with exciting hands-on STEM activities.
We also learned how leading companies such as Boeing and Procter & Gamble (P&G) are shaping the future. Appropriate for students of all ages, this event includes activities geared towards grades 4-8.
Share this online experience with your students, parents, and communities so they can all join the fun from wherever they are available on-demand now.
Participate in the Activities
In this experiment, students discover the power of chemical reactions. Through this reaction, carbon dioxide was created, which weighs more than oxygen. Fire needs oxygen and fuel to burn. If any one of these components were removed, the fire would go out. By placing the carbon dioxide over the flame, the carbon dioxide replaced the oxygen. Carbon dioxide suffocated the flame and extinguished the candles. And that’s how you make a fire extinguisher!
This experiment illuminates the changes taking place as light is refracted through water. Simply put, refraction is an optical illusion. Light bends when it passes from a substance of one density into a substance of a different density—in this case from air to water. Take the experiment further to see how the concave (turned inwards) surface of a spoon reflects images upside- down. Being a concave surface, the light waves hit the various parts of the spoon at different angles, so they’re all bent somewhat differently. By the time they’ve been reflected back at you, they’re all bending differently in a way that makes things look inverted (upside down).
In the battery powered car project given here, the transmission of the force from the motor to a wheel axle is carried through two gears and a rubber band that acts as a belt. To power up the car, we are using a battery in this experiment and a switch that connects and disconnects the circuit. The chassis of the car is made of plastic board, instead of the plastic wooden piece can be used as a chassis. Make sure the chassis is lighter so that the car moves forward effortlessly. After completing this project, you will explore many things, including Newton's Laws of Motion, design concepts, a concept of converting stored chemical energy into mechanical energy and a simple electric circuit.
Force and Motion Vocabulary
Gravity is by far the most familiar physical force, as we experience it every moment of every day. By dropping an object, the pulling force of gravity causes the object to inevitably fall to the ground the same way every single time.
