17. If it is the sun that is damaging the leaves on my fern, then moving it to a spot with less sun should stop more fronds from dying. The Scientific Method
18. If it is the sun that is damaging the leaves on my fern, then moving it to a spot with less sun should stop more fronds from dying. HYPOTHESIS! The Scientific Method
19. If it is the sun that is damaging the leaves on my fern, then moving it to a spot with less sun should stop more fronds from dying. HYPOTHESIS! EXPERIMENT! The Scientific Method
21. Hypothesis- Bubble size depends on gum flavor Experiment- measure bubble size using different gum flavors The Scientific Method
22. Hypothesis- Bubble size depends on gum flavor Experiment- measure bubble size using different gum flavors Manipulated variable- gum flavor The Scientific Method
23. Hypothesis- Bubble size depends on gum flavor Experiment- measure bubble size using different gum flavors Manipulated variable- gum flavor Responding variable- bubble size The Scientific Method
24. A controlled variable is something that could affect the outcome of your experiment, so because it is not of interest it must be removed or kept constant for every trial. Controlled variables- Brand, quantity, … The Scientific Method
25. Failure to identify and control competing factors can make an experiment invalid . The Scientific Method
26. The best experiments have just one manipulated variable and all other variables are controlled. The Scientific Method
27. The best experiments have just one manipulated variable and all other variables are controlled. This makes it certain that changes in responding variables are a result of that one experimental manipulation because it was the only thing different. The Scientific Method

35. Hypothesis - an explanation Experiment - tests hypothesis Theory - an explanation that is supported by so many different experiments that we agree it is TRUTH. Scientific Law - what happens The Scientific Method
36. Hypothesis - an explanation Experiment - tests hypothesis Theory - an explanation that is supported by so many different experiments that we agree it is TRUTH. Scientific Law - what happens LAW- Ships disappear on the horizon Old hypothesis- the ship falls off the world because it is flat Current theory- the ship moves out of view because the world is a sphere.

Observation is an essential step in the scientific method.
Observation is an essential step in the scientific method.
The steps in the scientific method do not have to occur in the order shown. Comparing and Contrasting How are a hypothesis and a theory similar? How are they different?
