Introduction
1) What was the purpose of the experiment?
2) What were the independent, dependent, and control variables in your investigation? Describe the variables for each part of the experiment.

3) Write a hypothesis based on observations and scientific principles. Your hypothesis should be in an If....then....because form.
***Here is a non-related example: If the amount of sugar added to the lemonade is increased then more people will buy it because people crave the extra sweetness.





Experimental Methods
4) What tools did you use to collect your data?

5) Write your procedure. List each step so that another student could follow the procedure and repeat your experiment.

Data and Observations
6) Record your data in a data table. You can use the table below. Do not hesitate to modify the table to fit your needs (you can right click to insert or delete columns/rows). You can also make a data table on paper and upload a picture.

Data Table:
A B C
.3
.2
.1







Conclusions
7) What conclusions can you draw about how the sum of forces acting on an object affect its motion? Write an evidence-based claim.

8) Which mass, A, B, or C, was the greatest? Use the observations from your experiment and your knowledge of Newton’s laws of motion to write an evidence-based claim.

9) Make a model that shows the forces acting on two blocks on a flat, frictionless surface:

• A 1 N block at rest
• A 1 N block with 2 N of force applied in one horizontal direction
Include arrows to represent the forces and labels to indicate the magnitude of each force. Use your model to compare and explain the motion of each block.
