A well uses a wheel and axle to pull buckets of water up from the bottom of a hole. The wheel is the handle you turn in a circle. The axle is the rod across the top that the rope winds around. As you turn the handle in a big circle, the axle turns in a small circle. The wheel does not need much force to travel a long distance. That means turning the wheel to lift the bucket is easier than pulling the bucket up by hand.

A paddleboat uses a wheel and axle to help it move across the water. The wheel is attached to the axle. The boat’s engine turns the axle, which makes the big wheel turn. Education The engine uses a lot of force to turn the axle. For each full turn, the axle turns in a small circle and the wheels turns in a big circle. This makes the wheel move the boat a long way. ® 6 Un bateau à roue utilise une roue et un essieu pour se déplacer sur l’eau. La roue est connectée à l’essieu.

The steering wheel in a car is a wheel and axle. The steering wheel does Education not actually turn the tires of the car. It turns the steering column (the axle) that works with the machinery inside the car to turn the wheels. It would be very hard to turn the small steering column itself while driving. The steering wheel needs less force to turn it but you have to turn in a bigger circle. ® 12 13 8 1 - 1 - 13 Le volant dans une voiture se compose d’une roue et d’un essieu.

Ramps are inclined planes – sloped, flat surfaces that may or may not be smooth. When Education you move an object along an inclined plane, you use less force than if you lifted it straight up or put it straight down. However, you have to travel a longer distance to get it to the same place. The longer the ramp, the less force you need to do the job. ® 6 7 Les pentes sont des plans inclinés - des surfaces en pente qui peuvent ou non être lisses.

8 7 11 10 1 - 11 A wedge is a special kind of inclined plane made of two flat slopes, back to back. When you Education hammer the splitting wedge into a crack in the log, the wood on the sides of the wedge spread apart. The further you push the wedge into the log, the bigger the crack gets until the log breaks. The wedge lets you use less force to separate the objects but you have to cover a greater distance.

The distance around the screw’s threads is much longer than the screw itself.
education.com K’NEX Building Basics To begin your model, find the 1 and follow the numbers. Each piece has its own shape and color. Just look at the pictures, find the pieces in your set that match and then connect them together. Try to face your model in the same direction as the instructions while you build. The arrows show you where the parts connect, but not all connection points have arrows. Faded colors show you the section has already been built.
