At the start of every Fortnite match, players fly in on the battle bus. What energy transformation occurs as players jump from the bus to the battle arena?
Gravitational potential energy to kinetic/ mechanical energy
200
Heat energy or thermal energy is a subtype of this energy?
Kinetic energy
200
What is the energy transformation that happens in photosynthesis?
Light energy to chemical energy

This feature of a wave determines how loud a sound is or how bright/ dim a light is?
Amplitude

A radio wave traveling through the air changes direction when it hits colder, more dense air. The radio wave still makes it to the car driving through the cold weather. What wave transformation occurred to the radio wave?
Refraction

In Fortnite, you need to break down trees physically into wood in order to build different structures. This is comparable to an organ in the human body, which is mostly responsible for breaking food down physically.

Fireworks are exciting any time of the year when they do this energy transformation. I love how they look and sound.
Chemical energy to light energy and sound energy.

Photosynthesis happens here inside plant cells.

Draw an example of a transverse wave.
Label amplitude and wavelength.
Model should go up and down where wavelength is from crest to crest and amplitude is the height of a crest from the rest position.

Digital signals are limited in this way. It's why all cell phones have a build in digital to analog converter (DAC).
Digital signals are 1s and 0s. They need to be changed into an analog signal in order for us to understand and process them.

Dancing is a common activity in Fortnite to celebrate a win, communicate with other players, and other things. What is the energy transformation that a living person would do in order to do a Fortnite dance?
Chemical energy to Mechanical energy

A pendulum is constantly alternating between these 2 types of energy.
Gravitational potential energy and mechanical energy/ kinetic energy
400
What is the balanced chemical equation for photosynthesis?
6 CO2 + 6 H2O yields C6H12O6 + 6O2
400
Which color of the rainbow has the highest energy? Why does that color have the most energy?
Blue/ violet.
Because it has the highest frequency/ shortest wavelength.
400
Draw a model of a digital wave. Explain how it makes digital waves harder to interfere with.
Square wave.

If we use a Fortnite battle royale as a model for a food web, what would be the role of the player at the top who was not killed be? There are 2 acceptable answers.
Tertiary consumer
Apex predator

A rock climber has 10,000 joules of energy. He slips and falls towards the ground. The rope stretches as it catches him absorbing 3,000 joules of energy and friction from the belay device changes the remaining energy to heat catching the climber just before he hits the ground. How much heat energy does the belay device gain in this fall?
7,000 joules

Where do plants gain most of their dry mass from?
Air
Carbon Dioxide

A guitar player plays a beautiful low note that is quiet, then he plays a note that has more energy. Describe the a possible changes to the note that would increase its energy and how it would sound?
There are 2 possible answers
Increased amplitude means it would be louder.
Increased frequency/ lower wavelength means it would sound higher. (higher pitch noise)

A DvD uses a series of flat sections and pits to store information. A laser shines on the disk and bounces back on the flat sections and does not bounce back on the pits. What type of signal does the DvD use? Explain your response.
Digital signal.
The signal is a yes or a no. It is not continuous.
