Soil

Texture depends on-

• color

• particle size

• plant growth

• the amount of sunlight soil gets

Clay is...

• never sticky.

• does not hold water well.

• does not contain many nutrients.

• sticky, holds water well, and has nutrients.

True or False. Iron rich soils appear to be red.

• True

• False

Students tested the capacity of a soil to retain water. They poured 200 mL of water through a funnel holding the soil. How many milliliters of water was retained by the soil sample? (Write the number only)

If students are investigating the texture of different soil samples, what would be the best procedure to follow?

• Compare each of the samples with a color chart

• Pour water into each of the soil samples

• Attempt to grow plants in each soil sample

• Moisten the samples and rub them with their fingers

Students test the amount of water retained by different types of soil. Equal amounts of soil were added to four funnels with filters, then the same volume of water was poured through each soil sample. To determine the amount of water retained by each soil sample, the student would –

• Add the amount of each soil sample to the volume of water poured in.

• Divide the total volume of water poured in by the number of samples.

• Subtract the volume of water collected from the volume poured in.

• Multiply the volume of water poured in by the number of soil samples.

Which property of soil could students determine by rubbing a sample between their fingers?

• The texture of the soil

• The soil’s ability to support life

• The color of the soil

• The processes that formed the soil

A sieve is a container with very small holes in the bottom that are all the same size. What would this tool be useful for?

• Sorting soil by particle size

• Finding the mass of soil

• Growing plants in soil

• Determining soil color

Students are comparing samples of different soils to the bars on a chart their teacher gave them. What property of soil are they trying to determine using this chart?

• Size

• Texture

• Color

• Shape
