- 5.Choose the statement that is a hypothesis.

Placing water in containers increases evaporation rate.

- 14.Brittany wrote a conclusion for a STEM Fair project. Read herconclusion below:The question I investigated was, “Does the drop height of a ball affect the bounce height?” My hypothesis was supported. The results showed when the ball was dropped from a height of 30 cm, the bounce height was 20 cm; when the ball was dropped from a height of 50 cm, the bounce height was 35 cm; and when the drop height was 70 cm, the bounce height was 50 cm. One thing I can infer from this investigation is that bounce height is affected by drop height. I would also like to investigate if bounce height is affected by temperature.Which of the following is missing from Brittany’s conclusion?
- A.
The hypothesis
- B.
Data from the investigation
- C.
The question she investigated
- D.
Whether the hypothesis is supported or not supported
