Project planning. As you plan your science project, use your lab notebook to capture the questions you hope to investigate, your hypothesis, and your variables.
Research Question
What are the soil strengths for soils with different moisture levels?
Research Hypothesis
H1: We hypothesise that soils with higher moisture levels will have greater shear and tensile strength.
Independent Variable
the moisture level of the soil
Dependent Variable
Shear and Tensile strength of the soils
Control Variables
(a) Mass of soil
(b) Same hand held shear vane device
(c) Same location of the experiment
