Mary's data showed that warm water dissolved an Alka-seltzer tablet faster than cold or room temperature water. This is the step of the scientific method she is currently at.
What is drawing conclusions?
300
Hypothesis: The higher the temperature of water, the faster an egg will cook. What is the Independent Variable?
What is the temperature of water?

Sara said, "If geranium plants receive 24 hours of direct light, then they will grow taller than plants that receive 0 h or 12 h of light because they use the light to perform photosynthesis." This is the step of the Sci Meth she is doing.
What is developing a hypothesis?

Hypothesis: Lemon trees receiving the most water, produce the largest lemons. Identify the IV and DV.
IV- amount of water ; DV - size of lemons.

This type of graph is used to graph data over time.
What is a line graph?

An experiment was done with 6 groups of children to see if the amount of spelling practice affected their spelling test scores. Name at least 3 controlled variables that should be held constant so the only difference is the amount of practice.
TBD- what are the spelling words, the place where students took the test, general spelling ability, time given for the test, time of day the test was given, etc.

This type of graph is used to show how parts or percentages make up a whole.
