Watts Up with the Freezer	We decided to do some home testing of a standard basement freezer with the Watts Up Pro power meter. How much energy is used, and how cold does the freezer get when the compressor is running? To find out, we used a LabQuest and a Watts Up Pro to log the data over a 48-hour period. The graph tells an interesting story and raises several questions: Why is the pattern so regular? Why does every other spike in the temperature data go so much higher? What happens to the power use when the te... [more] Science Subjects: Physics	Vernier LabQuest Logger Pro 3 Watts Up Pro

How Do You Dim an LED?	Have you ever seen an LED-based headlamp that has selectable brightness? Sometimes the brightness change is from turning on more or fewer LEDs, but sometimes the individual LEDs seem to change brightness. How does this work? Usually when you reduce the voltage across an LED, it just goes out. We looked into this question using a Vernier Light Sensor and a LabQuest. You could do this with any visible light sensor and a computer or calculator interface. The first clue was an observation: ... [more] Science Subjects: Physics	Light Sensor Vernier LabQuest
What a Drag!	A customer called recently looking for ideas on aerodynamic drag experiments. This inspired us to do a little research with toy cars on the roof of a car. We mounted two toy carts: one streamlined, and one not as aerodynamic. They were connected so that our Dual-Range Force Sensor would measure the drag force on them as we drove them along through the air. Our team of investigators included a driver, a computer operator, and someone to yell out the speedometer readings. We collect...
