A worker is constructing playground equipment for the park and dropped a box of nails and bolts. How will a magnet be helpful to the builder?

Gravity will cause the magnet to pick up the nails and bolts. 

⊝

• Gravity will cause 

  the magnet to pick 

  up the nails and

   bolts. 

• Friction will cause 

  the magnet to push away the nails and 

  bolts. 

• The magnet will 

  push the nails and 

  bolts away from it. 

• The magnet will pull the nails and bolts 

  toward it.

Students put a small wooden ball on the end of a spring. They dropped the ball and watched it bounce up and down. One student explained that gravity was the only force making the ball move. Which of the following is a weakness of this explanation?

• The ball is too small.
  

• The ball weighs very little.
  

• The ball fails to touch the floor.
  

• The ball sometimes moves upward.

Which describes the texture of a soil that BEST keeps water from flowing through?

• soft and spongy

• coarse and loose

• fine and tightly packed

• well mixed, not too coarse or fine

• Coal and plants are both nonrenewable 

  resources because they come from within the Earth's layers.

• Oil and coal are both renewable 

  resources because 

  they are naturally occurring and come from the same place.

• Chickens and coal 

  are both 

  nonrenewable resources because they are natural resources that can be replaced over time.

• Plants and chickens are renewable

   resources because 

  they have a life cycle and can be replaced in a short time span.

Resources can be classified as renewable or nonrenewable. Which of these resources is classified in the same category as coal?

• Wood

• Wind

• Corn Oil

• Petroleum

• 1. The soil in Picture 1 has a texture of large gravel that retains water and supports roots for healthy plant growth.

• 1. The soil in Picture 2 is grainy and dry which supports plants growing in a rainforest because roots can easily grow.

• 1. The soil in Picture 3 is moist and loosely packed which supports deep roots and strong, healthy plant growth.

• The soil in Picture 4 has a silky-smooth texture that supports deep root growth for strong and healthy plants.

A student places 250 g samples of clay, sand, gravel, and silt in separate flower pots. The pots are set on a wire rack, and dishes are placed beneath the pots so that water can drip through holes and collect. The student then pours 100 mL of water over the sample in each pot. The student measures the time it takes for water to begin dripping from the bottom of each pot.

• The differences in texture between wet and dry soils.
  

• How well different soils retain water.
  

• How much water is needed to dissolve different soils.

• The amount of time it takes different soils to dry.
