Inertia and Mass lab
Annotated Digital Jigsaw (ADJ)
Table leaders will equally assign sections of the text below (1-min). Each member of your group will then read and annotate their section of the text in silent mode (3-min). Readers must make notes (text tool) and underline content to help them restate the main information during their share time. After the 3-min bell, each member will take turns sharing the content with the other group members (1-min share time each student). (7-min total
Materials: Plastic track PVC, 4 round same volume but different mass objects, ramp stand, pencil support, measured foam track slope & stand

Create a testable question that can be answered using the materials & equipment provided.
Keep in mind the lab name/topic, current vocabulary, background info & video example to help create your question.
What is your Hypothesis? (If/Then statement)
1) Do a trial run with a ball to practice measuring the ball momentum on the metric ruler.
2) Weigh each ball and record as the information will be needed when graphing and recording in the data table.
3) Place the 1st test ball (you pick) at the top of the track (be consistent with the starting point) and release. Record the height (top of ball) on the foam track that the ball reaches.
4) Roll each ball 3 times. Record in the data table (cm) then average data (Test 1 + Test 2 + Test 3 รท 3 = Average ramp height reached)
5) Graph the average ramp height of each ball (y-axis) with reference to the object's initial weight (on the x-axis)
6) the video example above
Use the data table below to list your lab measurements and data values to be graphed.
Make a line graph, label Ave Roll Distance (cm) on vertical Y-axis, and Inertia/Mass (grams) on the X-axis. Also, make a catchy title & label key.
What are your results? Restate your graphed data (calculations) in words.
What is your conclusion?
Your conclusion must include:
1) A restatement of the question.
2) The answer to the question.
3) State whether your hypothesis was correct or incorrect.
4) Use data collected during the lab to backup your answer and hypothesis.
