Mr Olsen is running an experiment. He is seeing if the color of light affects the growth (cm) of plants. He will have one plant and per color of light and will measure twice a day randomly.
Which suggestion below would help improve his experiment?
He could test brighter colors.
He could test lights that are further away.
He could increase the number of plants he tests.
He could measure in inches instead of centimeters.

a summation of the data collected during an experiment.
when a question is tested using a procedure.
a suggested explanation based on available information.
Mr. Einstein is running an experiment on the effects of metals on electricity. He will be using different materials and measuring their resistance to electricity. He will test wood, steel, plastic, and copper. He will test each material 3 times.
What is Mr. Einstein's dependent variable?
Type of Metal
Resistance to electricity
The number of trials
The time of day he does his experiment
