Term 1 Week 4 Electronics

Today M1 learnt about electricity with Andrew. He made a light sensor with us which could sense the level of light in the area we were in. He gave us a LED light and a button battery. The button battery had a side that had a plus on it which meant positive, and a side which had dots on it called the negative side. The LED light had two wires one was longer than the other which meant that it was the positive side. So you put the big wire on the plus side of the battery and then you put the smaller wire on the side where its smaller than the other so the battery is in between so then the LED light will light up.
How to make a light sensor
You put you're LED light in an Data Base without the battery. Then you put your light sensor in the data base then you go somewhere you think is cold or hot. We put ours in the milk bucket filled with milk cartons the LED light will flash how many digress it is. If it is a short flash it means 1 if it is a medium flash it means 10 if it is a long flash it means 100 we got 12 digress.

 Has Andrew ever been to your school?
