How could you incorporate wheel and axle into a Pumpkin Puller?

skewer and straw, lego wheel and metal rod,...

200

True or False. A Wheel and axle is a shaft that is
attached to the center of a larger wheel so that they rotate separately.  

•False: Wheel and axle – a shaft (axle) that is attached to the center of a larger wheel so that they rotate together

How does a pulley reduce work?

By reducing the effort needed to lift an object by increasing the distance over which the effort is applied.

200

How does an inclined plane make work easier?

It is easier to slide a heavy object up the flat, slanted surface rather than carry it from one level to another.

You distance that you need to carry the load will increase, but it will require less force to move it.

200

How does a lever reduce work?

The lever makes doing work easier by reducing the force needed to move an object. In order to reduce the force needed, the distance over which the force is applied must be increased.

200

True or False: a screw is an inclined plane wrapped around a cylindrical post. 

True! 

200

How does a wedge make work easier?

A wedge reduces the amount of force needed to split objects. 

200

The lever length and fulcrum position are the same in each of the diagrams below. Which box will be easiest to lift? Explain.

300

Why do gears have teeth?

The teeth allow gear to interlock with each other causes them to rotate one another.

300

What vocabulary word should be under the red arrow in this picture?

Effort or applied force

300

True or False: All inclined planes make work much easier. Explain.

False! A steep inclined plane may not help make work easier as the amount of force will not be greatly reduced.  

300

This is the word for the point on which a lever rests or is supported and on which it pivots?

The fulcrum

300

Where is pitch on a screw?

Pitch is the distance between the threads. 

300

True or False: a wedge is two inclined planes put together to make a point. Explain.

True! 

300

A machine that is made of two or more simple machines is called a

Compound Machine

400

True or False: a pulley system also utilizes a wheel and axle. 

True! A pulley system uses a grooved wheel attached to an axle and a rope to rotate it. 

400

True or False: Part C in this diagram is a movable pulley. Explain

False. Part C is a fixed pulley because it is fixed to one spot (it does not move). 



400

You are moving boxes into a moving van. Point to where the effort or force is coming from in this diagram: 

The force is coming from pushing the box up the ramp from the bottom. 

400

True or False: the further the load is from the fulcrum, the easier it is to move. Explain

False! The closer the load is to the fulcrum, the easier it is to move. 

400

What is another term for the ridges on a screw?

Threads

400

How is a wedge different from an inclined plane?

A wedge is used to split things apart, an inclined plane is used to move objects from one level to another.

The big difference between a wedge and an inclined plane is that, while the inclined plane stays still, a wedge moves to do its work.

List and point to the simple machines you see in this picture: 

Pulley

wheel and axle

500

How do wheels reduce work?

They reduce work by reducing the amount of friction used to move an object. 

500

True or False: Part B in this diagram is a movable pulley. Explain

True! It is not fixed to one spot, so it is able to move. 

500

What are three actions you can use with an inclined plane when moving an object?

push, pull, or roll. 

500

True or False: The wheelbarrow is an example of a lever. If so, where does the effort come from, where is the load, and where is the fulcrum?

True!  Your hands on the handles give the effort. The load is inside the wheelbarrow. The wheel is the fulcrum.

500

What is the main part of the screw called in which the threads wrap around?

The shaft. 

500

True or False: all wedges are meant to be moved in order to do their job. Explain


False. Some wedges are used to prevent movement, such as a door wedge. 

500

What is the name of a machine that uses lots of combinations of simple machines that are used together in a sequence to accomplish a simple task?

Rube Goldberg Machines
