Janelle wants to investigate to determine three different soils’ textures based on their particle size.  She says “I only need to use a hand lens to look at them.  Then I will write down what I see.  This will tell me all I need to know about their texture based on their particle size.” Is Janelle correct in her thinking?

• Yes, because a hand lens helps you see particle size and then you will know about the soil's texture.

• No, because in order to determine texture you need to know what the soil feels like.

• Yes, because to see texture you just need to look at the soil closely.

• No, because you do not need to use a hand lens to determine texture.

Leah 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.
