Heat Transfer STEM Project

By now, you should know about how heat is transferred​. Today, we're going to use that knowledge to do a challenge!

​

​

​Heat Transfer

​

​​Before we start, let's review the main concepts.

​

​If you can't remember something, that's okay. These questions will remind you!

​

​

Multiple Choice

What causes your skin to feel warm when it is in the sun on a summer day?

• Particles in the atmosphere reflect energy from the Sun downward

• The Sun radiates energy that passes through space & the atmosphere to your skin.

• Hot particles from the Sun still carry some heat when they reach your skin.

• The solar wind carries heated air from the Sun’s atmosphere to Earth’s surface.

Multiple Choice

Which best describes the flow of heat?

• A. From a larger object to a smaller object

• From a cooler object to a warmer object

• From a warmer object to a cooler object

• From a warmer object to a warmer object

Multiple Choice

You hold a bowl of hot soup that warms your hands; this is

• A. Radiation

• B. Conduction

• C. Convection

• D. Conviction

Multiple Choice

Steam from a hot bowl of soup warms your face as you lean over it; this is

• B. Conduction

• C. Convection

• D. Conviction

Multiple Choice

Why is it better to have a cooking pot with a plastic handle instead of a metal handle?

• A. Plastic looks better than metal.

• B. . Plastic is not a good conductor of heat

• C. Plastic washes easier than metal.

• D. Plastic is a good conductor of heat

Multiple Choice

Jim wakes up early in the morning and walks from his carpeted bedroom to the tiled kitchen. Which BEST describes why, despite being the same temperature, the tile floor feels cooler to his feet than the carpet?

• A. Tile is a better conductor of heat and transfers heat away from his skin.

• B. Carpet is a bad conductor of heat and transfers heat to his skin.

• C. Tile is a poor conductor of heat and transfers heat to his skin.

• D. The tile and carpet are the same temperature

Multiple Choice

Napat wants to determine the best material to make a new type of cooking pan. What type of material should he choose?

• A. A material that conducts heat evenly.

• B. A material that can be easily bent into shape.

• C. A material that does not transmit electricity

• D. A material that will remain cool to the touch.

Multiple Choice

• Convection

• Radiation

Multiple Choice

Multiple Choice

Carole owns a two story house with a heating and cooling unit on each floor. In the winter she mostly uses the downstairs unit to heat the house because the volume of warm air __________ and __________, warming the whole house through __________.

• expands and rises, convection

• expands and sinks, conduction

• contracts and rises, conversion

• contracts and sinks, conduction

Multiple Choice

If two objects have different temperatures, heat will flow from the warmer object to the cooler one UNTIL ____________.

• one reaches a temperature of zero

• they both have an equal temperature

• one runs out of energy

Multiple Choice

Which of the following is the best example of radiation?

• The ocean breeze

• Using a laser to shape a diamond

• Eating ice cream

• A wave knocking over a sandcastle

Multiple Choice

As water in a freezer turns into ice, ___________.

• the water absorbs energy from the air in the freezer.

• the water absorbs the coldness from the air in the freezer.

• the freezer air absorbs heat from the water.

• the water neither absorbs nor releases energy

Multiple Choice

Are the particles moving faster or slower as time goes on? (Diagram F)

• Faster

• Slower

Multiple Choice

An ice cube feels cold when we hold it. Which of the following best explains why?

• Heat moves from our hands into the ice cube.

• Cold moves from our hands into the ice cube.

• Heat moves from the ice cube into our hands.

• Cold moves from the ice cube into our hands.

Multiple Choice

Which will most likely occur when a raw egg is placed on black pavement on a hot, summer day?

• The pavement will conduct heat and cook the egg.

• The egg will reflect heat and make the pavement hotter underneath.

• The egg will absorb heat  and leave the pavement hotter underneath.

• The pavement will absorb heat from the egg, and the egg will stay raw.

Multiple Choice

Energy transfer during which hot fluid rises and cold fluid sinks, creating a cycle, is called...

• Heat

• Convection

• Radiation

• Conduction

​Just like the previous challenge, you will be in teams for this activity.

​

5 groups of 4 students and 1 group of 3 students.

​

The groups must be different from your previous groups! ​

​

​

​

​Heat Transfer Challenge

​1) Design a fully functional solar oven that you can use to cook food.

2) Make a draft outline and make a list of the materials that you will need.​

​​What You Need to Do Today

​

​1) The goal is to make a solar oven that can make 4 smores (1 for each team member) in the fastest amount of time.

2) ​Give a short presentation explaining the design of your solar oven, how it worked and how it can be improved.

​​Goals for this Project

​

Remember that your teams must be different from the last project teams.​

​

One person can be the same but not more than that!​

​

​

​Now we need to make teams and start.

​

​Some of your score will come from the work in your notebook. So please put all of your plans in there.

​

​

​​Get those notebooks out!

​

​You may use a tablet/iPad but at the end, you will need to print out your notes and staple then into your paper notebook.
