Rosa wants to investigate three different types of soil for their ability to retain water. She comes up with two different plans.

Which is the BEST plan to investigate the three types of soil for their ability to retain water?

• Plan 1 because you can measure the specific amount of water the soil retained.

• Plan 2 because you can look at the soil and see how much water is in it.

• Plan 1 because you do not need to use colored water.

• Plan 2 because it used colored water.

Sonia wants to find the best soil for planting pumpkin seeds. She has a choice of three different types of soil. She knows that the pumpkin seeds need water, but too much or too little water will not be best for the seeds. Using the information in the table above, which soil should Shania’s use to plant her pumpkin seeds?

• Loam would be the best soil because it retained more water and allowed the most water to be filtered through.

• Sand would be the best soil for the pumpkin seeds because it retained less water than clay.

• Loam would be the best soil because it retained less water than clay but more water than sand.

• Sand would be the best soil for the pumpkin seeds because it allowed the most water to be filtered through.

Ximena shook a bottle filled with water, clay, pebbles, and sand. He put the bottle down. After 3 hours, the bottle looked like the image below. What can Ximena conclude based on what it saw in the bottle?

• The sand grains are larger than the clay grains.

• Sand grains are larger than pebbles.

• Clay grains are larger than sand grains.

• Clay grains and sand grains are the same size.

If a student wanted to tell if a soil is mostly sand, what could they do to identify the soil and why?

• They could feel the texture because sand is slippery when wet.

• They could add water because it will pass through sand easily.

• They could add water because sand holds the most water.

• They could look at the particle size because sand has the smallest particles.

A student wanted to find out what type of soil could grow lima beans the best. What would be the best investigation to carry out?

Alexandria has three different samples of soil. She knows one is clay, one is sand, and one is gravel, but she can’t remember which is which. What is one way she can determine which soil is which and why?

• She can add water to the three soils. Sand and clay will absorb the same amount of water. Then you will know which is which by its color. Gravel will absorb the least amount of water.

• She can observe the texture of the three soils. Gravel feels smooth when wet, sand feels rough and rocky, and clay feels gritty when rubbed.

• She can use a color system to observe the three soils. Clay is usually black, gravel is a combination of white and blues, and sand is usually a red/yellow color.

• She can use a hand lens to observe the particles of the three soils. Clay has the smallest particles, gravel has the largest particles, and sand’s particles are in between.
