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

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?

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

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

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

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

• Gather data through observations/
  measurement
