Are you strong enough to pull two sheets of paper apart? What about two books with the pages intertwined? Watch this experiment performed by Ruben Meerman, the Surfing Scientist, and find out how he tests the presence of friction between pieces of paper.
GAMES
Push and pull online experiment
Label the forces in action
Push or Pull? Sort the forces
Push, Pull or Twist?
Shoot a disc at a target to score goals. Control the direction of the disc by applying linear forces. Use a single linear force, then combine multiple forces. Play a match where you score points by aiming accurately
Run experiments in a plant research laboratory. Investigate the effects of different variables on the growth of lettuces, peas and tomatoes. Research the answers to questions about how to achieve optimum hydroponic growth conditions. Examine the effect of key variables on growth: nitrogen, temperature, light intensity and light duration.
Hard push, soft push
Adjust the materials and design for the rollercoaster keeping in mind the effects of friction (rolling resistance and air resistance) to find out if the rollercoaster is successfully safe
Experiment and learn how forces and friction are connected
Find and click on "MAGNETS AND SPRINGS" down the list. Magnets have north poles and south poles. These attract each other. But two north poles will repel each other, as will two south poles.
When a spring is stretched or squashed, it creates a force.
Explore the parts of an electromagnet circuit. Test objects made of different materials to find out whether they are affected by magnetic fields. For example, discover whether a rubber band is deflected by the field of an electromagnet
