Throwback Check for Understanding! 12/1

Each time you measure in science you need to determine the best units in the correct measurement system. We want to make sure we use the right units in our grocery cart lab. The proper units in our lab for height/distance are (a)   . The proper units for force are ​ (b)   . The proper units for mass are ​ (c)   .

• grams
• centimeters
• Newtons
• pounds
• inches
• feet
• ounces

Make a scatterplot with this data:

Mass : Force

2 g : 4 N

4 g : 6 N

6 g : 8 N

What part of the experiment gives you something to compare your results to, so that you know that the changes really affected the outcomes and not something else?

What is a claim in an experiment?

• A way to cancel data

• A summary of the problems in the experiment.

In an experiment, you usually follow some basic steps. Think back to our grocery cart lab. Based on that, what is the order of how we should conduct experiments?

• Interpret the data (What I See - WIS) to look for patterns

• Analyze the data (averages, graphs, etc.)

• Make a claim (What it Means - WIM) to answer the testable research question + hypothesis

• Design the experiment (IV, DV, constants, etc.)

• Gather data through observations/
  measurement
