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?
No because in order to determine texture you also need to know what it feels like.
