PHYS 1.1 Formative

How do you verify a scientific hypothesis?

• with experiments

• by making observations

• by comparing it with other hypotheses

• by making it a theory

Einstein's most famous equation is E = mc². In this equation, E stands for energy, m stands for mass, and c stands for the speed of light. Use algebra to solve this equation for mass.
That is, complete this equation: m = ?

A detailed explanation of some aspect of nature that accounts for a set of well-tested hypotheses.

• scientific theory

• independent variable

• inference

• scientific method

You develop an experiment to observe plant growth based on the type of fertilizer you use. You choose 5 different fertilizers and measure the height of the plants once a week for 4 weeks. What is the independent variable in this experiment?

• type of fertilzer

• plant height

• amount of fertilizer

• type of plant

In the scientific method, when would you develop a hypothesis?

• after you have made initial observations

• after you perform an experiment

• it would be your first step

• after you draw conclusions
