STEM stands for a cluster of careers in the fields of:

– Science– Technology– Engineering– Math

STEM QuotesSTEM Quotes• “STEM fields are collectively considered core technological

underpinnings of an advanced society.” National Research Council and the National Science Foundation.

• “The strength of the STEM workforce is viewed as an indicator of a nation's ability to sustain itself.”

President George W. Bush

What Does a STEM career really Mean?

Any field or career that:• Creates, Discovers or Applies New

Knowledge to Make Life Better for All!

In Other Words...In Other Words...STEM careers :• Search for new methods, and ways to

understand things better • Work effectively and efficiently to solve

problems• Require you to innovate, create, & discover• Ask why and how things need to be built,

invented, repaired and designed

A Brief History of STEM

STEM Activity

Typical heater and air conditioning fan circuit

This is a schematic (drawing) of the circuit

MOTOR

The battery is the source of power for the circuit. The power from the battery comes from an electric chemical reaction caused when two types of metal (Lead phosphate and sponge lead) are submerged into a solution made of sulfuric acid and water.

MOTOR

Wires are needed in a circuit to conduct current to the component. Wires are typically made of copper covered in plastic. Wires are shown in a diagram in two ways. 1.Crossed over one another but not touching. 2. Crossed over each other and connected

MOTOR

Resistors are needed in a circuit to control the current flow. They can be used to slow down motors like in the heater fan cirtcuit or lower the intensity of a light like in the dash light circuit.

MOTOR

The lamp is considered a load or form of resistance in the circuit. It will consume power. The consumption of power is measured in watts (like what you see written on light bulbs and other electrical component.

MOTOR

The motor is also considered a load in the circuit. It’s purpose is to change electrical energy into rotational energy.Motor speed can be controlled by placing resistance in line with it.

MOTOR

A switch is a control device that is used to turn the circuit on and off or used to control where current flows in the circuit.

When you turn on a switch in a circuit current will flow through the circuit.

Current makes the circuit work. Like the fan motor in this circuit will spin when current is applied to it.

The amount of current that flows through the circuit can be adjusted by adding or taking away resistance.

Trace the power flow on your handout.

In this circuit the blower speed switch has been changed to medium speed 2.

The current then bypasses 2 of the in line resistors.

And the motor speed increases.

Trace the power flow.

In this circuit the blower speed switch has been changed to high speed.

The current then bypasses all of the in line resistors.

And the motor speed increases to as fast as it can go

Trace the power flow.

NOTICE THE SPEED OF THE MOTOR WHEN YOU TURN IT ON? THIS IS AS FAST AS IT CAN GO!

Now Let’s Try a Light

Bulb Instead of a Motor

NOTICE THE INTENSITY OF THE LIGHT WHEN YOU TURN IT ON? THIS IS AS BRIGHT AS IT CAN GET!

So far we have built a motor circuit and a light circuit.

Alone in the circuit the light will glow as bright as it will get and the motor will go as fast as it will go.

What will happen if we put the two in a row?

NOTICE THE INTENSITY OF THE LIGHT AND THE SPEED OF THE MOTOR?

THIS IS CALLED A SERIES CIRCUIT

Bring STEM to LifeBring STEM to Life

This simple exercise brings STEM to life for the circuit builders. It is fun and easy and teaches by creating.

This is the same type of creative STEM workshop that UTI offers to high school students. They leave understanding the importance of Science, Technology, Engineering and Math and the career opportunities that STEM represents

Bring STEM to Life in Your High Bring STEM to Life in Your High SchoolSchool

1. Connect students with STEM role models2. Promote STEM in tangible and real-life

oriented ways3. Provide guidance curriculum which

encourages students to explore STEM careers.

4.Introduce STEM to High School Students/Parents

5.Encourage/support teachers to demonstrate STEM career pathways in class

6.Add problem-solving classroom activities
