SPEED! CRANK STEAM ACTIVITY GUIDE AERODYNAMICS ! QUE TOR 4+
HEY HOT WHEELS ® FANS! HOT WHEELS® SPEED WINDERS™ ARE RUBBER BAND-POWERED VEHICLES THAT LET KIDS RACE, EXPERIMENT, AND DISCOVER DIFFERENT WAYS TO PLAY WITH ENERGY! ! S L A I R E T MA HERE’S WHAT YOU’LL NEED FOR THE EXPERIMENTS: Speed Winders™ Twisted Cycle™ L et’s get into the science behind your Hot Wheels® Speed Winders™! All motorcycles and cars have engines that create energy to make them move. Your Speed Winders™ vehicle has an engine, too: A RUBBER BAND.
#1: ELASTIC FORCE SPEED LAB! T he more times you turned the crank, the farther your Speed Winders™ vehicle should have traveled. That's because of TORQUE- a force that tends to rotate or turn things. T HOW MUCH POWER CAN YOU CREATE FOR YOUR SPEED WINDERS™ VEHICLE? HERE ARE THE STEPS FOR THIS EXPERIMENT: 1 3 5 Turn the crank on your Speed Winders™ vehicle 3 full times, place it behind the starting line, and launch it. R Measure the distance it traveled using your ruler or measuring tape.
#2: IS BIGGER ALWAYS BETTER? D ! B A L D E SPE G id the length of the rubber band affect how far your Speed Winders™ vehicle traveled? How about the thickness of each rubber band? That's because rubber bands of different lengths and thicknesses have more or less STRETCH. R DID YOU KNOW YOU CAN USE ALMOST ANY RUBBER BAND TO POWER YOUR SPEED WINDERS™ VEHICLE? emember what we already learned about potential energy. The more energy you store, the more is released as kinetic energy.
#3: DUAL ENGINE DYNAMICS SPEED LAB! EVER WONDER WHY SO MANY REAL RACE CARS LOOK SO SLIM AND SLEEK? IT’S BECAUSE THEY’RE BUILT FOR SPEED! L et’s see how the shape of a Speed Winders™ vehicle affects how far it can travel. 1 s you can see, the distance each of these 3 vehicles traveled is different from each other. One reason is because they have different shapes. The shape of a vehicle affects its AERODYNAMICS, which is the study of how air affects moving objects.
#4: FRICTION IS A STICKY SUBJECT ! B A L D E SPE FRICTION IS WHAT KEEPS US FROM SLIPPING AND FALLING ALL OVER THE PLACE. IT IS A FORCE THAT HOLDS BACK THE MOVEMENT OF A SLIDING OBJECT. W TEST LOG TYPE OF SURFACE SMOOTH AND FLAT DISTANCE TRAVELED (INCHES ) ROUGH AND BUMPY ant to see friction in action? Try this! 1 Turn the crank on your Torque Twister™ 5 times. Launch it on your kitchen floor or other smooth, flat surface. Then measure the distance it has traveled using a ruler or measuring tape.
#5: SUPER ENGINES OF THE FUTURE SPEED LAB! TEST LOG CONSTANT IMPROVEMENTS IN TECHNOLOGY CHANGE THE WAY WE LIVE AND INTERACT WITH THE WORLD. I n the auto industry, engineers design vehicles that can be powered by lots of different kinds of energy, such as gasoline and electricity. In order to keep up with changes around us and test our limits, we have to keep innovating. INNOVATION is the process of introducing new ideas, devices, or methods.
