Energy and Heat
This is defined as "the ability to cause change."
What is Energy?
This kind of wave requires matter to travel through. If there is no matter, the wave doesn't travel.
What is a Sound/Mechanical Wave?
What is Convergent?
Understanding energy allows us to change forms of energy into each other, like how dams change the energy of moving water into electrical energy. This is called ____.
What is Energy Transformation?
White light is a combination of all of the colors of the visible spectrum. We know this because if we shine white light through a prism, the light bends at different angles for each color's wavelength. This bending is called _____.
What is Refraction?
Scientists don't just take each other at their word, we have to check each other's work. That why we do _____, which is when we copy each others' investigations to see if we get the same results. The more we do this, the more we can trust the results.
What is Replication?
Describe the energy transformation taking place when a pencil falls to the floor.
What is Frequency?
The mantle of the Earth can be as hot as 3700 degrees Celsius. At this temperature, rock is turned partially liquid and begins churning up and down in a circle. This movement is called a ______ current.
What is Convection?
At the San Andreas Fault in California, the North American plate and the Pacific plate are sliding past each other and scraping their sides. As they move, they cause huge fractures in the crust. These huge fractures are called...
What are Earthquakes?
When a car comes to a complete stop, the kinetic energy of the car is converted into _____ energy. This explains why the tires get so hot.
What is Thermal Energy?
The red apple on my desk appears that way because it reflects red light into your eyes. All other colors are ______, which means the apple stored that light energy as thermal energy.
What is Absorbed?
DAILY DOUBLE!
In any experiment, we MUST be directly manipulating something to cause a change something else. Answer the following question in order: Which variable do we change directly and which variable do we watch for changes?
If you put an ice cube on a hot pan, it quickly melts into water and then evaporates into steam. The water is changing states of matter so quickly because heat is being transferred from the pan to the water by ______.
What is Conduction?
As you move across the Electromagnetic Spectrum, the wavelength and frequency change in opposite directions: as one increases, the other decreases. This is called an ______ relationship.
What is Inverse?
