Electronics

We have been learning about simple circuits, resistance and insulation using 9 volt batteries an LED and Play Doh. 

We have been exploring how electricity works and what is a simple circuit. We are starting to use technical language and most students now understand that there is a positive and negative side of a battery and a LED. However, bulbs and most electric motors do not have a positive or negative side. We introduced resistors and resistance explaining that this is the amount of energy required to ‘push’ electricity through a certain material, and some materials have a lower resistance than others. The challenge was a simple one but it created a lot of discussion and experimentation until they could get the LED to light up. The students worked in two’s with some great collaboration and learner agency taking place. At the end of the lesson, the students reflected using Seesaw.

Student Voice

“We thought this was not going to be very interesting but it was really cool and harder than we thought” Abbey.

“Today we learned to make a circuit out of Play-Doh and batteries we learnt about different wires, red is positive and black is negative. To make a circuit the Play-Doh can't touch each other otherwise it will turn off.  We used the Play-Doh as a resistor if we didn't have a resistor the light would blow out. We also made a turtle with LED eyes. Abbey and I thought it was very interesting”. Emma
