Why do scientists conduct experiments?

• To make a lot of money.
• To ask a question. 
• To make a hypothesis.
• To prove a prediction is correct.

What are the steps in the Scientific Method?

• Ask a Question, Make a Hypothesis, Do Background research, Conduct an Experiment, Analyze your data, Report your results. 
• Ask a Question, Make a Hypothesis, Analyze your data, Do Background research,  Conduct an Experiment,  Report your results.

An experiment is a when scientists test their hypothesis, or prediction. They carefully plan their test, and decided what the variables will be. A manipulated variable is the one thing that 

• will change in the experiment.
• will stay the same in the experiment.

What does a line graph do?

• Show change over time.
• Collect categorical data.
• Compare quantities.
• Measure quantities. 

What does this graph show?

• Average Daily Temperatures
• Average Monthly Temperatures
• Weekly Daily Temperatures
• Daily Temperatures

Why do scientists write down everything they do when they conduct experiments including the materials they use, the procedure they follow, and the results they concluded. 

• In case other scientists want to check their work.
• To make sure they did everything correctly.
• Their boss wants to see all of their work.
• To make sure they do everything correctly.
