100

These are worn in a lab to protect your eyes.

What are GOGGLES?

100

This tiny building block is the smallest part of an element that still keeps its chemical properties.

What is an ATOM?

100

This state of matter keeps its shape and size.

What is a solid?

100

This is the space taken up by matter.

What is volume?

100

Acids have this type of flavor.

What is sour?

200

This is used to hold and mix liquids during experiments.

What is a BEAKER?

200

This is a negatively charged particle found in an atom.

What is an ELECTRON?

200

This state of matter takes the shape of its container but keeps the same volume.

What is a liquid?

200

This is a combination of substances that are NOT chemically bonded together.

What is a mixture?

200

Bases feel like this to the touch.

What is SLIPPERY?

300

This is used to transfer small amounts of liquid one drop at a time.

What is a PIPETTE?

300

This is a positively charged particle found in the nucleus of an atom.

What is a PROTON?

300

This state of matter spreads out to fill all the space around it.

What is a gas?

300

This force pulls molecules together on the surface of a liquid.

What is surface tension?

300

This type of product often contains a base.

What is soap?

400

This is used to hold small samples during testing or heating.

What is a TEST TUBE?

400

This is a neutral particle found in the nucleus of an atom.

What is a NEUTRON?

400

This is what we call the three forms matter can exist in: solid, liquid, and gas.

What are the states of matter?

400

This happens when surface molecules of a liquid turn into a gas.

What is evaporation?

400

This substance releases hydrogen ions (H⁺) in water.

What is an ACID?

500

This is used to measure the exact volume of a liquid.

What is a GRADUATED CYLINDER?

500

This is the dense center of an atom where protons and neutrons are found.

What is the NUCLEUS?

500

In this state of matter, particles move the most freely and are farthest apart.

What is a gas?

500

This is when particles spread out from one place to another.

What is diffusion?

500

This substance releases hydroxide ions (OH⁻) in water.

What is a base?
