In the Scientific Method, once you have a question you would like an answer to, you must formulate a hypothesis. A hypothesis is an educated guess or potential answer to your question. A hypothesis allows you to create an experiment that is most suited to answering your question and achieving accurate results.
On the ACT Science Test, Consistent with Hypothesis questions will ask you whether or not the given data supports a singular hypothesis. If data supports a hypothesis, it means that the educated guess you made at the beginning of the experiment was correct.
Below is a sample passage from the ACT Science section that features Consistent with Hypothesis questions. We will reference this passage when attempting to answer the questions.
The following question tests your understanding of the passage above as it relates to hypotheses.
This question is asking which of the following hypotheses are best supported by the information provided in Table 1 and Figure 1.
Table 1 shows how the volume of Material A changes over time. From the passage, we know that Material A is absorbing heat at a rate of 10 calories per second.
We can see from Table 1 that the volume of Material A is increasing over time, as it continues to absorb heat.
Figure 1 shows the temperature of Material A over time. From 0-2 seconds, the temperature increases from -10℃ to 10℃, and then stays constant at 10℃ until 22 seconds as a liquid and gas mixture. At 22 seconds, Material A becomes a gas and the temperature rapidly increases.
Based on Table 1 and Figure 1, we can see that the volume of Material A was increasing even when the temperature did not increase.
We can see from Table 1 that the volume of Material A is still increasing after 22 seconds, when it becomes a gas.
Therefore, the answer choice that contains a hypothesis that is supported by the table and figure is answer choice G: when the temperature of gaseous Material A increases, the volume increases.
