Physical Science
A form of energy that travels in straight lines and allows us to see our surroundings.
Light
The rigid outer part of the earth, consisting of the crust and upper mantle, is called this.
Lithosphere (or geosphere)
What are the three subatomic particles that make up an atom?
Protons, electrons, neutrons
This gelatin-like substance holds all the organelles in place.
Cytoplasm
What type of energy is stored in an object because of its position, height, or state before it begins to move?
Potential energy
This scientific tool is made of a triangular piece of glass that can separate white light into the full rainbow spectrum.
Prism
This is the name of the supercontinent that existed millions of years ago before drifting apart.
Pangea
Group 18 contains unreactive, stable gases like Helium and Neon. What are they called?
Noble gases
This jelly-filled organelle stores water, food, and waste.
What is the ultimate source of energy that drives the entire water cycle by evaporating water from oceans and lakes?
The sun
The nerve that acts as a cable carrying visual messages directly from the retina to the brain.
Optic nerve
This type of plate boundary is formed when two tectonic plates move apart from one another, creating features like mid-ocean ridges.
Divergent boundary
If an atom has 6 protons, 6 neutrons, and 6 electrons, what is its mass number?
12
This organelle converts glucose into usable energy for the cell.
Mitochondria
What is the green pigment found inside plant chloroplasts that absorbs sunlight for photosynthesis?
Chlorophyll
The type of lens that is thicker in the middle than at the edges, causing light rays to meet at a single focal point.
Convex lens
The Himalayan Mountains were formed by the collision of two continental plates at this type of boundary.
Convergent boundary
Is a rusting nail an example of a physical or chemical change?
Chemical change
The primary organ in the immune system that produces white blood cells.
Bone marrow
What type of mixture is uniform throughout, meaning you cannot visually see the different parts, like saltwater or clean air?
Solution
The type of mirror used in security and convenience on city buses, which curves outward to provide a wider field of view.
Convex mirror
This type of rock is formed from the cooling and solidification of magma or lava. (Hint: It's found in the Earth's crust)
Igneous rock
Thermal energy (heat) does this to the speed and movement of particles.
Which organelle is known as the "powerhouse of the cell" because it generates most of the cell's energy?
Mitochondria
In an ecosystem, what do you call an organism that cannot make its own food and has to eat other plants or animals for energy?
A consumer
