Is pencil conductive?
Simon was trying to make a circuit using graphite pencil as conductor but it wasn’t strong enough to make an LED burn. We actually measured the voltage with the multimeter … Continue reading Is pencil conductive?
Kirchoff’s Current Law
On Monday Simon’s math tutor and I agreed that Simon should try some problem solving involving both math and electricity, considering his current interest. We chose Electricity and Magnetism > Current … Continue reading Kirchoff’s Current Law
Ohm’s Law Applied to Lemons
Simon wrote a poster with electricity formulas (from memory) this morning and applied one of them (Ohm’s law) to his advanced lemon experiment. We had already tried this experiment … Continue reading Ohm’s Law Applied to Lemons
Joules per second
The new Adventures in Science video episode by SparkFun is out! This time on electric power.
Simon calculates colour probabilities. #RRGGBB
In the video below Simon applies his knowledge of combinatorics to calculate the total number of possible colours one can create in CSS. I didn’t ask him to do this. … Continue reading Simon calculates colour probabilities. #RRGGBB
Science Journal app
Simon loves his new Science Journal app he recently found online and downloaded on my Android. The app allows him to investigate movement (by using accelerometers), measure ambient light and sound … Continue reading Science Journal app
I Feel the Heat!
Mom, I’m going to build a heat generator!
Always happy to teach
It’s late in the evening. While drinking his bedtime tea Simon is teaching his little sister to measure the voltage of various batteries. And he also knows his Ohm’s Law … Continue reading Always happy to teach
Our desktop’s guts
I saw Simon looking at all the ports on the back of the desktop processor this afternoon and asked him if he wanted to take a peep inside. He was … Continue reading Our desktop’s guts
