Performance Task:
|
|
|
In this activity you will investigate how
temperature affects the rate of diffusion. Your task is to make an
hypothesis about this relationship and design an experiment that will test
that hypothesis. You have the following materials available to you for your
experiment:
Ice water cold faucet water cups/petri dishes/beakers hot water food
coloring graduated cylinder After completing your experiment, you are to
draw logical conclusions, using proper scientific terms. In your science
journal, write a brief report, stating what your hypothesis is, the
procedure you followed in carrying out your experiment, and any controls
you built into your experiment. Discuss any variables used in the experiment.
Record any data collected and make a visual presentation, such as a graph,
of that data. Explain how your investigation either supports or nullifies
your hypothesis.
