Today the class was to add alight sensor to their robots.
Then they programmed them In Investigator to collect light sensor data while moving 2 seconds forward and back.
The light areas are high on the graphs and the dark are low.
Once they got a feel for how the data looked from different runs
Mrs. Salter stated them at a secrete spot
and the students uploaded the data and tried to figure out the starting and stopping spots.
One group proved that they were right by drawing the data from her run and making a new run.
That graphs matched!!!
Then the class had a second secret trial.
They were able to upload their data, check out the graph and point out the start and stop correctly.
