Summary

This is a 5 days Track focus on learning basic circuits theory and fundamentals in addition to Micro-controllers ( parts and operation ). Also we will make some applications using the micro-controller and the participant will be asked to build their own project at the fifth day.

Day 1 : Basic Circuits

Day 2 : Computer and Micro-controller

Day 3 : Basic Component

Day 4 : Advanced Component

Day 5 : Project

What You'll Need

This track is unplugged so you will find all the needed applications online for free.

The Instructions

Introduction ( Ice breaking )

In this section we will start by a wondering question to grab the attention of the kids and also get them involve to interact.

1- What do you know about electricity also can we live without it?

2- Usually kids says it power the stuff and it’s all around us.

3- We want the kids to understand that electricity is like water it flows in paths, but we call the particles “Charges”

4- We will introduce the scientific name of each the plug and the battery.

5- Also we will list some examples for devices uses DC and AC together.

What is Circuit

In this section we will introduce the circuit and why we call it a circuit.

1- Circuit : is a path for the charges to flow from point to point and it’s a closed one.

2- Circuits look like a circle as if we start from a certain point we will end at the same point again, This why we call it a circuit.

3- In circuits we have two different state opened circuits and closed circuits.

4- Closed circuits : forms a complete loop with no cuts.

5- Opened circuits : the path is not complete due to one of the wires is not connected or one of the component is corrupt.

Circuits Parts

We will talk about what make the circuit a circuit, and we will discuss each one briefly.

1- Circuits do consist of 3 main parts: “Voltage Source, Conductive paths, and Loads”.

2- Voltage source: is the component that provide power to the circuit “Battery”

3- Conductive paths: Is the component that provide routes for the charges to flow from one point to another.

4- Load : is the component in the circuit required to consume the power and make something from for example light bulb consume power to emit light and motor do consume power to move.

Circuit fundamentals

In this section we will discuss the current, voltage, and Resistance.

1- Current : is the flow of charges at a certain point, Also current carry power from the voltage source to the Load.

2- We can mention that we measure current by a unit called ampere “Amps”.

3- Voltage: is the amount of pressure the power source can provide, Also volts pushes the current to move in wires.

4- We can mention the unit of voltage which is volts”V”.

5- Resistance: is the opposite force in direction to the Voltage, However, every this in life do have resistance.

6- We can mention the unit of resistance which is Ohm” Ω

Note: We want the participant to know these stuff without mentioning more details.

Practical

In this section we will give the participant the chance to make simple circuit, also they can show more creativity and try many ways of building circuits.

1- We will use a platform from University of Colorado “PHET Colorado“.

2- Here we want the participant to try making a circuit, also to see how current flows and how increasing the voltage and decreasing it affect the current, in addition to have a look at the resistance and the effect of it increase and decrease.

 

Micro-controllers ( Day 2 ) (Introduction)

In this day we will introduce microcontroller to the participant also they will have the chance to simulate applications using Tinker CAD platform.

1- We usually start with a quick review to the last day by letting the participant to summarize. Also, we ask some questions to refresh their memory.

2- After that we should give a quick brief about what we are going to learn today.

3- Then we will start by asking questions about the computer to introduce what come next.
