Plant Growth Experiment
Maria conducted an experiment to see how different amounts of sunlight affect plant growth. She used three identical plants and placed them in different locations for two weeks. She measured their height at the end of each week.
Plant Growth Data (Height in cm)
| Plant | Sunlight | Week 1 Height (cm) | Week 2 Height (cm) |
|---|---|---|---|
| A | Full Sun | 5 | 8 |
| B | Partial Shade | 4 | 6 |
| C | Low Light | 3 | 4 |
Based on the data, which plant grew the most over the two weeks?
What can you conclude about the effect of sunlight on these plants' growth?
If Maria wanted to continue this experiment, what is one new question she could investigate?
Sugar Dissolving Experiment
Experiment Scenario: Investigating Sugar Dissolving in Water
A group of 5th graders wants to find out if stirring affects how fast sugar dissolves in water. They decided to do an experiment. They took two identical cups, added 100 mL of water to each, and then added one spoon of sugar to each. In the first cup, they stirred the sugar and water constantly for one minute. In the second cup, they did not stir it at all. They observed which cup had the sugar dissolve faster.
Based on the scenario, what was the hypothesis for this experiment?
Identify the independent variable and the dependent variable in this experiment.
List two materials, besides sugar and water, that the students would need for this experiment.
