A Sample of Animals
Betty Robinson and her scientist parents are studying animals in the Amazon Rain Forest. The population of animals in the rain forest is very large, so Betty and her parents study a sample of the animals. They have chosen a small area of the forest to investigate. They identify the types of animals they see in this area and count the number of each type of animal. The two main variables in their experiment are the type of animal and the number of each type.
They use the TIMS Laboratory Method to help them solve problems. First, they draw a picture of the steps they will follow in the experiment.
Then, they collect and organize the data in a data table.
Next, they graph their data.
Finally, they analyze and discuss their results.
When you have a problem, you, too, can use the tools of science to solve it. We call these tools of science the TIMS Laboratory Method.
