100

This metric unit is commonly used to measure the mass of an object in a chemistry lab.

gram

100

Convert 5 meters to centimeters.


What is 500 centimeters (500 cm

100

This is the thin, solid outermost layer of Earth where we live.

crust

100

This organelle is known as the "control center" of the cell because it contains DNA and directs all cell activities.

nucleus

100

This geological process breaks rocks into smaller pieces without moving them.

weathering

200

This metric unit is used to measure the volume of a liquid.

liter

200

Convert 2.5 liters to milliliters.

2,500 milliliters (2,500 mL)

200

This is the thickest layer of Earth and is made of hot, slowly moving rock

mantle

200

This organelle is often called the "powerhouse of the cell" because it produces ATP (energy) through cellular respiration.

mitochondrion (mitochondria)

200

This process moves rock and sediment from one place to another by water, wind, ice, or gravity

erosion

300

This metric unit measures the length of an object.

meter

300

Convert 4,500 milligrams to grams.

4.5 grams (4.5 g)

300

This layer is made mostly of liquid iron and nickel and is responsible for generating Earth's magnetic field.

outer core

300

This organelle is found in plant cells and uses sunlight, water, and carbon dioxide to make glucose through photosynthesis.

chloroplast 


300

his theory explains that Earth's crust is divided into large moving plates that cause earthquakes, volcanoes, and mountain formation.

plate tectonics

400

This metric unit is used to measure temperature in most science laboratories around the world.

degrees Celsius (°C)

400

A student measures 750 centimeters. How many meters is this?

7.5 meters (7.5 m)?

400

This is the hottest and most dense layer of Earth, made primarily of solid iron and nickel.

inner core

400

A scientist discovers a cell that contains a cell wall, chloroplasts, a large central vacuole, mitochondria, and a nucleus. Is this a plant cell or an animal cell?

Plant cell

400

Name Earth's four main layers from the outside to the center

crust, mantle, outer core, and inner core?

500

Name the four most commonly used metric units in chemistry and what each measures.

What are grams (mass), liters (volume), meters (length), and degrees Celsius (temperature)?

500

A chemistry lab needs 3 kilograms of a substance. How many grams is this?

3,000 grams (3,000 g)

500

Starting from Earth's surface, name the four main layers of Earth in the correct order.


What are the crust, mantle, outer core, and inner core

500

Which organelle produces ATP?

Mitochondrion (mitochondria)

500

This is Earth's thin, rocky outer layer where humans and most living organisms live.
