Introduction to the //control.Node
This activity explores all the features of the //control.Node in preparation for performing sense and control experiments with the Motorized Drawbridge,...
Raise the Drawbridge in Response to a Signal
Operate the Drawbridge in response to a signal. The signal comes from the 3-axis accelerometer in...
Using the Load Cell as a Limit Switch
Learn to use a load cell and Blockly code to make the Drawbridge automatically stop when it touches...
Explore the Effect of Gear Ratios
Why does the Drawbridge have an 18-tooth gear driving a 72-tooth gear? What happens if you replace them with different gears? In this investigation you...
Explore the Effect of the Drawbridge Counterweight
Why does the Drawbridge have a counterweight? What happens if you remove it? In this investigation...
Measure Loads in Drawbridge Supports
A rectangular base supports the drawbridge. How do the loads at the front and back corners compare? How do they change as the drawbridge moves up and down?...
Measure Loads in Top and Bottom Beams of the Drawbridge
Are the top and bottom beams under compression or tension? How do the loads change as the drawbridge...
Raise and Lower the Drawbridge
Using Blockly code in PASCO Capstone or SPARKvue software, program the Drawbridge to move up and down.
Build the Drawbridge
This activity has detailed directions for assembling the Motorized Drawbridge (ME-7028).
Enthalpy of Change
Students use a Wireless Temperature Sensor, a calorimeter, and Chemvue software to calculate enthalpy and track the flow of energy into or out of a system...
