Demo: BTB and Carbon Dioxide
I have used this demonstration every year to introduce the scientific method. The worksheet below is optional and includes instructions for writing a lab report and doing a more involved investigation, but for the beginning of the year, I prefer to just have students observe and give their suggestions for how to test various hypotheses.…

Scientific Method in Action
This simple worksheet has two reading passages, similar to what students may see on state standardized science tests. Students read a short description of a science experiment and must answer questions related to science methodology, such as identifying controls and variables and summarizing conclusions that can be drawn from the text. The two stories are…

Investigation: How Much Water Is In a Plant?
Students compare the amount of water in three types of plants: a root (carrot), a fruit (grape) and a leaf by weighing samples and dehydrating them overnight.

Investigation: Plop Plop Fizz Fizz
This investigation asks beginning students to develop a hypothesis about how quickly an effervescent tablet will dissolve and then design an experiment.

Scientific Method – Answering Causal Questions
Examine a flow chart which considers a question about water evaporation; hypotheses are proposed to test the effects of air flow, light, and temperature.

How Can the Scientific Method Solve Real-World Problems?
Read short stories about how scientists used the scientific method to solve real problems, such as the discovery of penicillin and the cause of beriberi.

Investigation: What Are the Processes of Science
Inquiry investigation where students develop hypotheses to answer a question about lung capacity, design an experiment, collect data, and draw conclusions.

Scientific Method Scenarios
students work in groups to develop an experiment that answers a question. Students design the experiment, and must also identify the a control group and the independent and dependent variables in their experiment.
