name two tools lee used to complete his experiment.
does the data shown in the table above support lees prediction? explain why or why not.
lees teacher says that lee should communicate his results to other scientists. give one reason that it is important for scientists to communicate their results to one another.
look at the amount of time that it took the warm water in trial g to boil. what is one possible explanation for this trial having such a different outcome from the other three warm water trials?

Explanation:

1. For the first question, a timer is used to measure the time it takes for water to boil and a thermometer is used to measure the starting temperature of water.
2. For the second - the data shows that on average, water starting at 100°F boils faster than water starting at 70°F, so it supports the prediction.
3. For the third - communication of results allows other scientists to replicate the experiment, verify the findings, and build on the research.
4. For the fourth - possible reasons for the different outcome in Trial G could be variations in heat source (e.g., inconsistent heating), measurement errors (e.g., inaccurate timer or thermometer readings), or presence of impurities in the water.

Answer:

1. Timer, thermometer
2. Yes, because on average water starting at 100°F boils faster than water starting at 70°F.
3. Allows for replication, verification, and further research.
4. Inconsistent heat source, measurement error, or presence of impurities.
