Motion Graphing Made Easy with PASCO

When teaching physical science, motion is by far my favorite unit. You can do so many fun experiments ranging from motion graphing and building rockets to Newton’s laws demos. Any time you can incorporate graphing into the curriculum it is great since creating and reading graphs is a skill that will help students throughout both math and science.

One product you can use for motion graphing is PASCO’s wireless motion sensor. This sensor works on bluetooth and is completely wireless, so students can move around the room without worrying about tripping over cords. If you have laptops you can even do your lab outside where you have more room to space out! Simply charge the motion sensor with a USB cord and it’s ready to go.

To use the motion sensor, you need to download PASCO’s free Match Graph software. (This was the only hiccup I had when using the motion sensor- if you are using school computers that require I.T. approval to download any software, you will have to put in a help desk ticket. Once it was installed by my tech department it worked like a breeze).
When you load Match Graph, you will see a main screen where you can switch between position-time graphs and velocity-time graphs. I always start with position-time graphs because they seem easier for the students to grasp. Next, have the students in each group type their name in the top so they can all take turns (more on this in a minute). When students are ready to begin, I have them hold a large whiteboard (any large flat surface works) in front of them- this seems to help the motion sensor detect them easily. The students will need about 4 meters of clearance behind them, so space your groups out around the room. 

Once students hit record, a red line will appear on the screen and show their motion. The goal is for them to match the template shown on the screen. Students can change out between 9 different templates for each graph type. I like to let students play around with this lab before I’ve actually taught what position-time and velocity-time graphs look like. This allows students to use inquiry and figure out the difference between the two types of graphs.

Each time they take a turn Match Graph shows a score in the bottom right corner of the screen. This is GREAT for easy grading. All you have to do is walk around the room, have them pull up the scores under their name, and you can record their highest score. It gets competitive!

The front of the sensor turns 180 degrees, so you can turn the sensor so it faces up, place it on the ground, and measure the motion of objects in free fall. Have students explore gravity, air resistance, and gain a deeper understanding of slope. (I always try and time this unit at the same time students are learning slope in algebra). Match Graph is truly user friendly and you won’t have issues with students trying to learn how to use it. Your students that are kinesthetic learners are never going to forget this lab!
