What happens when water demand is more than the water resource? (HINT: i'm looking for the specific vocab work for it)
Water Scarcity
I'm running an experiment to determine which type of water is the best for growing underwater plants. I purchase 3 of the same size tanks and get 3 of the same type of underwater plant. In one tank I use 60% salt water, in the second tank I use 75% salt water and in the last tank I use 90% salt water. After One month I check how much each plant has grown. What is the independent, dependent and control variable in this experiment?
Independent: Percent salt water
Dependent: plant growth
Control: Tank size, underwater plant
When two molecules have the same amount of thermal energy they have reached this
Equilibrium
How does wind change a shoreline?
Wind pushes waves into the beach which causes weathering. The same waves also then cause erosion to carry the broken down pieces away to a new place
What causes energy to transfer?
What is the difference between an Atom and Molecule?
An atom is the smallest unit of measurement for an element, a molecule is two or more atoms together
What is the reasoning portion of claim, evidence and reasoning?
The reasoning applies the evidence and claim to a new issue. It also explains how the evidence supports the claim.
