Science Olympiad Detector Building event

The Science Olympiad’s newest Div. C event, Detector Building, is now one of the 23 approved events for this year’s competition. Texas Instruments (TI) has plenty of resources to help your team be competitive.

The Detector Building event combines coding, engineering, math and science into a working sensor that is calibrated and coded to collect data. The program students write will cause various LEDs to turn on or off based on the temperature readings. During the competition, students must adjust their code and calibration equation to closely match that of a store-bought digital thermometer.

Driving Inequalities

In this Math in Motion Plus activity, students will write their own program for the TI-Innovator™ Rover. Students will explore inequalities and the number line while writing code to navigate a set of challenges. They will apply their knowledge of compound inequalities to write programs for Rover to demonstrate the inequalities on the number line.
