Completing Conclusions
A proper conclusion should restate the hypothesis and compare that hypothesis to the data observed during the experiment. If the data agree with the prediction, we say the hypothesis was supported. If the data don't agree with the prediction, we say the hypothesis was refuted. When deciding whether the hypothesis is supported or refuted, it is important to consider the data and the background information.

For experiment A, the hypothesis predicted the reaction would be
. The temperature changed from
to

For experiment B, the hypothesis predicted the reaction would be
. The temperature changed from
to
. Because the temperature
, the reaction must be
. The hypothesis was
by the data.
For experiment A, the hypothesis predicted the reaction would be supported. The temperature changed from [initial temperature] to [final temperature]. Because the temperature [increased/decreased], the reaction must be [prompted/stalled]. The hypothesis was supported by the data.
For experiment B, the hypothesis predicted the reaction would be refuted. The temperature changed from [initial temperature] to [final temperature]. Because the temperature [increased/decreased], the reaction must be [prompted/stalled]. The hypothesis was refuted by the data.
For experiment A, the hypothesis predicted the reaction would be [select option: 'supported' or 'refuted']. The temperature changed from [select option: 'initial temperature'] to [select option: 'final temperature']. Because the temperature [select option: 'matches the prediction' or 'does not match the prediction'], the reaction must be [select option: 'supported' or 'refuted']. The hypothesis was [select option: 'supported' or 'refuted'] by the data.
For experiment B, the hypothesis predicted the reaction would be [select option: 'supported' or 'refuted']. The temperature changed from [select option: 'initial temperature'] to [select option: 'final temperature']. Because the temperature [select option: 'matches the prediction' or 'does not match the prediction'], the reaction must be [select option: 'supported' or 'refuted']. The hypothesis was [select option: 'supported' or 'refuted'] by the data.
