Energy
This type of energy is stored in an object because of its position, like a rollercoaster sitting at the top of a hill.
potential energy
The process where liquid water heats up from the sun and turns into water vapor (a gas).
evaporation
This thin, protective outer layer surrounds all cells and controls what goes in and out.
cell membrane
highest point of a wave
Crest
Unscramble this star that provides heat and light energy to Earth: N U S
Sun
The energy of motion, possessed by anything that is moving.
kinetic energy
The process where water vapor cools down and turns back into liquid water droplets, forming clouds.
condensation
Often called the "brain" or control center of the cell, it houses the cell's DNA.
nucleus
The distance from the crest of one wave to the crest of the next wave.
wavelength
Unscramble this visible form of energy that travels in straight lines: T H I L G
light
This law states that energy cannot be created or destroyed; it can only change forms.
law of conservation of energy
Rain, snow, sleet, or hail that falls from clouds to the Earth's surface.
precipitation
This green organelle is found only in plant cells and captures sunlight to make food.
chloroplast
This type of wave, like a sound wave, requires a medium (like air or water) to travel through.
mechanical wave
Unscramble this fluffy white collection of water droplets in the sky: D U O L C
cloud
Heat transfer that happens when two objects are directly touching each other, like a metal spoon heating up in hot soup.
conduction
The process by which plants release water vapor into the air through tiny holes in their leaves.
transpiration
The jelly-like fluid that fills the inside of a cell and holds all the organelles in place.
cytoplasm
The bouncing back of a wave when it hits a surface it cannot pass through, like a mirror reflecting light or an echo reflecting sound.
reflection
Unscramble this basic unit of all living things: L L E C
cell
Energy resources like solar, wind, and water that can be replaced naturally in a short amount of time.
renewable resource
Water that does not soak into the ground but instead flows over the surface into streams, rivers, and lakes.
runoff
Organisms made up of only one single cell, such as bacteria or amoebas.
unicellular organism
The bending of a wave as it passes from one medium to another at an angle, which makes a pencil look bent when placed in a glass of water.
refraction
Unscramble this word for a disturbance that transfers energy from place to place: E V A W
