This piece of lab equipment is used to measure mass and has 3 beams.
What is a triple-beam balance?
This organelle is known as the control center of the cell and is where the DNA is found.
What is the nucleus?
This subatomic particle has a positive charge.
What is a proton?
This force pulls objects toward the Earth or toward any object with mass.
What is gravity?
This planet is the third from the sun in our solar system.
What is Earth?
This type of graph is usually used to show how something changed over time and has one or more lines created by plotting points.
What is a line graph?
Humans typically have 23 pairs of these, half inherited from each biological parent.
What are chromosomes?
This element, with atomic symbol C, is one of the main ingredients of life on Earth.
What is carbon?
This type of energy acts like both a particle and a wave and without it, you wouldn't be able to see.
What is light?
You experience this when the moon passes directly between the earth and the sun and blocks the sun's light from your point on Earth.
What is a solar eclipse?
This unit of measurement is the base unit for length in the metric system.

What is a milliliter?
This class of animals is known for having fur and giving birth to live young (not laying eggs).
What are mammals?
This element bonds with two hydrogens to create water.
What is oxygen?
This type of energy moves much slower than light and is why we often see lighting first.
What is sound?
This season occurs in the northern hemisphere when the angle of the sun's rays is most direct.
What is summer?
Scientists form one of these when they have a possible answer to a question.
What is a hypothesis?
This single celled organism makes up roughly 50% of the cells in and "on" the human body.
What are bacteria?
This compound is created when sodium and chlorine form an ionic bond.
What is sodium chloride or table salt?
Forces such as gravity are measured in this unit.
What is a Newton?
This phase of the moon occurs when the moon is between the Earth and the sun.
What is a new moon?
