What is mass? 

the amount of matter an object has. 

100

What is a solid? 

is a substance with a defined shape and volume. The atoms in solid are packed tight together. 

100

Which change of state is the result of matter cooling? (TEKS 3.5C) 

A. A gas becomes a liquid

B. A solid becomes a liquid

C. A liquid becomes a gas

D. A solid becomes a gas

A. A gas becomes a liquid

100

What is a physical change? List some examples. 

is where in which the shape, size, or state of the matter changes, but the substance is still essentially the same. 

Examples: folding, tearing, and cutting are all physical changes. 

100

What do we use to measure volume that is a liquid? 

a graduated cylinder in ml (milliliters) 

200

What is volume? 

The amount of space that matter takes up. 

200

What is a liquid?

is a substance that has a defined volume but no defined shape. The atoms in a liquid are packed less tight, but are still close together. 

200

When you heat up liquid what does it do?

It will boil and evaporate

200

What is a chemical change? List some examples. 

those where one or more substances are combined to produce a new substance. (cannot be changed back)

Examples: rusting, burning, bananas turning black. 

200

What do we use to measure mass? 

a pan balance in grams or kilo grams

300

What does evaporate/evaporation mean? 

the process of liquid changing into a gas from the process of heating. 

300

What is a gas?

is a substance that does not have defined shape or volume. The atoms of a gas are spread out and do not stick together. 
300

What does it mean to dissolve something? 

Dissolve- mixed but can not be separated. 

300

What are physical properties of an object?

size, shape, texture, hardness

300

What do we use to measure volume that is not a liquid? 

metric ruler (length x width x height) 

400

What does condense mean? 

to make smaller and more compact (tight) 

400

States of Matter with water, draw a picture (tell me how it changes between each state). 

(Picture) 

400

What is a solution?

Solution: something that is evenly mixed. Is the end result of dissolving.

Sarah planned the descriptive investigation described below: 

- Step 1: Measure 2 tablespoons of baking soda.

- Step 2: Measure 1/2 cup of vinegar. 

- Step 3: Mix the baking soda and the vinegar 

- Step 4: Record observations. 

In which step will a new kind of matter form? (TEKS 3.2A)

Step 3

400

In the table given find the final water level after the liquid has expanded through volume. (TEKS 3.2) 


Starting water level + Volume of object = final water level 


110 mL 

500

What does it mean to estimate? 

to calculate the approximate amount, size, or value of.

500

Which one is a solid? Which one is a liquid? Which one is a gas? 

Milk- liquid

TV- solid

Helium in a balloon - gas 

500

What is a mixture?

A mixture is two or more substances that are combined without changing any of them. 

500

What kind of change has heating eggs caused? (TEKS 3.5C) 

There was a chemical change because different substances have formed from the original substance that you cannot change back. 

500

Patty measures the volume of four objects. She places each object into a graduated cylinder of water, one at a time. She measures the starting water level and final water level each time. Patty constructs the table below to show some of her results. 

For which object with Patty record the largest volume? (TEKS 3.2C) 

Final Volume - Starting Volume = Volume of the object 

Golf ball
