Spectral Lines

Comparing the absorption of Heat

Comparing the absorption of Heat by heating two plates, one black and one silver with a light bulb and then comparing the heat loss when the bulb is off using @Pascoscientific temperature sensors and Capstone

Iodine in Cyclohexane

Ticker Tape Timing

 

With all the wonders of electronic sensors sometimes using some basic equipment like ticker tape timers to look at acceleration and how the lengths of tape get longer in the same time period aids the understanding.
