True or False
True or False: Convection occurs when you directly touch something.
False! Conduction is when heat transfer by two objects directly touching.
Name The Lie:
1. A lava lamp is an example of convection
2. A sunburnt face is an example of radiation
3. Cooking in a hot pan is an example of convection
The lie is #3! Cooking in a pan is an example of conduction. This is because the pan is directly touching the flame and the food it's cooking.
_________ is when heat is transferred from objects directly touching.
Conduction!
What type of energy is a battery?
Chemical Energy!
Who is correct?
Bobby says that heat from a stove burner is convection.
Sarah says that heat from a stove burner is radiation.
Sarah is correct! You can feel the heat waves from the stove burner.
True or False: A hot air balloon is an example of convection
True! The hot air is less dense so it rises and fills the ballon making it rise.
Name the lie:
1. Radiation is when you're directly touching an object.
2. A hot air balloon is an example of convention.
3. Radiation is waves of energy.
#1 Radiation is when heat is transferred by waves of energy when you're directly touching an object that is conduction.
_______ & _______ are the two most important type soft energy found in a roller coaster.
Kinetic & Potential!
What type of energy is inside a toaster?
Heat energy!
Who is correct?
Abby says that potential energy is always at the highest point of a roller coaster.
Nick says that kinetic energy is at the lowest point of a roller coaster.
Abby is correct! She is correct because potential energy is always at an objects highest point.
True or False: These are the three ways energy can be transferred: Radiation, Conduction, Convection
True!
Name the lie:
1. Sound energy is vibration through waves.
2. Sound can travel through long distance
3. Sound travels faster through a gas than a solid.
The lie is 3! sound travels faster through solids because the molecules are closer together.
The three most common types of graphs in science are _____, ________ & _______.
Pie charts, Bar graphs, & Line graphs!
What type of energy causes a TV to work?
Electrical energy!
Who is correct?
Mae says that chemical energy is stored in lightbulbs, lamps and LEDs.
Izabella says that chemical energy is in fireworks, rust, and your digestive system.
Izabella is correct! Chemical changes occur in fireworks, rust, and your digestive system.
True or False: Conduction is the movement of heat or electricity through fluids or gasses.
Name the lie:
1. Electrical energy is the total amount of kinetic and potential energy.
2. Gravitational energy is a form of potential energy.
3. Hydropower creates electrical energy.
1! mechanical energy is the correct answer.
X rays, microwaves, and radio waves, are all radiation and are examples of _________ ______.
Electromagnetic Waves! These are waves of energy that moves between objects.
What energy comes from deep underground?
Geothermal energy!
Who is correct?
John says that nuclear energy is produced by the fusion of electrical atoms.
Kiley says that nuclear energy is produced when reactions in an atom cause a structural change in the nucleus.
Kiley is correct! Nuclear energy is produced when reactions in an atom cause a structural change in the nucleus.
True or False: Convection is thermal energy transferred through a solid.
False!
Name the lie:
1. Chemical energy is potential energy that is stored in the bonds of chemical compounds
2. Hot water and steam from deep underground. This is called geothermal energy.
3. Light energy is also called electromagnetic conduction.
The lie is 3!
Light energy is also called electromagnetic energy!
_______ ________ is defined as the amount of work/energy needed per unit of electric charge to move the charge from a reference point to a specific point in an electric field.
Electric Potential!
What type of energy occurs when two nuclei of an atom combine and release heat and electromagnetic radiation?
Nuclear fusion!
Who is correct?
Ben says a boiling pot of water has more thermal energy than an iceberg.
Sarah says that the iceberg has more thermal energy.
Sarah is correct! This is because the iceberg has more mass.
