$200 Question from H2 What is work?

$200 Answer from H2 when a force moves an object through a distance that is in the direction of that force

$300 Question from H2 According to the definition of work - If you and your dad spend all day trying to move a bolder, but you can never get it to move, have you worked? Explain.

$300 Answer from H2 NO! because the rock didn’t move and according to the definition of work the object must move in the direction on the force.

$400 Question from H2 What is friction?

$400 Answer from H2 a force that resists the motion of one surface past another; friction creates heat

$500 Question from H2 Name three things used to reduce friction.

$500 Answer from H2 wheels, ball bearings, oil, grease, water, wax

$100 Question from H3 What is a simple machine?

$100 Answer from H3 a tool with only one or two parts that makes work easier; some examples of simple machines are inclined plane, wedge, lever, pulley, wheel and axle

$200 Question from H3 What is an inclined plane? Give two examples.

$200 Answer from H3 Give two examples. a flat surface with one end higher than another. 1.bicycle ramp 2.wheelchair ramp 3.a screw also has an inclined plane wrapped around it

$300 Question from H3 What is a wedge? Give two examples.

$300 Answer from H3 Give two examples. two inclined planes put together. 1.nail 2.knife 3.needle 4.axe

$400 Question from H3 What is a lever? Give two examples.

$400 Answer from H3 a bar with a fulcrum (balance point) 1.see-saw 2.pop top 3.crow bar 4.your arms swinging a bat

$500 Question from H3 What is a pulley? Give two examples.

$500 Answer from H3 a simple machine that looks like a wheel with a rope around it. 1.top of a flag pole 2. a pulley is at the top of a water well to pull up a bucket of water

$100 Question from H4 Tell what a producer is and give some examples.

$100 Answer from H4 an organism that makes its own food (a plant) 1.rose bush 2.tree 3.poison ivy

$200 Question from H4 Tell what a consumer is and give examples.

$200 Answer from H4 an organism that gets its energy from eating a producer or another consumer. 1.bug 2.snake 3.mouse 4.mountain lion 5.buzzard (also a scavenger, meaning it eats animals that are already dead)

$300 Question from H4 What is a food chain?

$300 Answer from H4 one path energy takes in a community

$400 Question from H4 Explain the difference between a food chain and a food web.

$400 Answer from H4 food chain is one path of energy and a food web is several paths that energy may take in a community.

$500 Question from H4 Explain photosynthesis.

$500 Answer from H4 it is the process by which plants make their own food. The plant needs water, CO2 and sunlight in order to make its own sugars. Leaves take in carbon dioxide, and give off oxygen during the process.

$100 Question from H5 What is an electric current?

$400 Answer from H5 A current that flows through a closed or complete path

$500 Question from H5 Describe what happens in a series circuit when you unscrew one of the bulbs.

$500 Answer from H5 All of the bulbs go out because you have opened the circuit and do not have a complete path
