Table 2 STEM Knowledge and Skills Pre/Post Survey

Electrical

I can explain Ohm’s law

I can indicate the value of an electrical resistance just by looking at it

I know the difference between alternating and direct current

I can measure voltage and electrical current

I can measure how much energy an electrical capacitor store

I can build an electrical or electronic circuit capable of exerting control

A photovoltaic cell converts solar energy into electrical energy

As the angle of incidence of light in a solar cell change, the amount of electrical energy converted changes

Electronic

I identify the symbols of a transistor, diode, capacitor, resistor, LED, photovoltaic cell, and motor

Transistors and diodes are semiconductors

I can calculate how much current a LED can receive without being damaged

I feel able to weld with tin and iron

I can unsolder an electronic piece of equipment

I can identify the polarity of a LED just by looking at it

I can solder using an electronic circuit as a guide

Mechanics

The direction of rotation of a direct current electric motor depending on the polarity of the power source

An electric motor transforms electrical energy into mechanical energy

Computational thinking

I can explain what an algorithm is

I can describe a process involving mechanical, electrical, and electronic elements using an algorithm

I can program the behavior of a BEAM Robot in a programming language

Recycling of WEEEs

I can recover from electronic equipment, elements such as a resistor, a capacitor, a motor, etc

Disposal equipment can be totally or partially reused
