Matter

$100 Question – Properties of Matter

Matter is anything that has ____________and takes up ______________.

$100 Answer - Properties of Matter

Matter is anything that has mass and volume.

$200 Question - Properties of Matter

The particles of matter are microscopic. What does this mean?

$200 Answer - Properties of Matter

Microscopic means that the particles are too small to be seen with the eye. A microscopemust be used to analyze them.

$300 Question - Properties of Matter

$300 Answer - Properties of Matter

B – a physical property

$400 Question - Properties of Matter

$400 Answer - Properties of Matter

A – graduated cylinder

$500 Question – Properties of Matter

$500 Answer - Properties of Matter

G – heat.

$100 Question – States of Matter / Physical and Chemical Changes

A B C

The models above show how the particles look in the three main states of matter. Identify the state of matter represented by each model.

$100 Answer – States of Matter / Physical and Chemical Changes

A = solid

B = liquid

C = gas

$200 Question - States of Matter / Physical and Chemical Changes

A

B

C

Name the three main states of matter that match the descriptions.

$200 Answer - States of Matter / Physical and Chemical Changes

A = liquid

B = gas

C = solid

$300 Question - States of Matter / Physical and Chemical Changes

What type of change has this matter gone through?

$300 Answer - States of Matter / Physical and Chemical Changes

A physical change.

When matter changes from one state to another(such as from a liquid to a gas, a solid to a gas,a solid to a liquid, a gas to a liquid, etc.) it has only changed physically. If a new substance is formed, or if light/heat are generated, this usually indicates a chemical change (ex: whenrust is formed, when an object is burned, etc.)

$400 Question - States of Matter / Physical and Chemical Changes

$400 Answer - States of Matter / Physical and Chemical Changes

A – melting butter.

This is a physical change because the butter hasonly changed states, from a solid to a liquid. Nonew substances were formed.

$500 Question - States of Matter / Physical and Chemical Changes

$500 Answer - 3 Main Types of Matter

B – heat it.

By baking the cake batter, it will cause the substances to change in such a way that a new substance is formed. Once as chemical change like this happens, it cannot be reversed.

$100 Question – Mixtures and Solutions

$100 Answer - Mixtures and Solutions

D – two or more different substances.

$200 Question - Mixtures and Solutions

What does the caption mean when it states, “In a mixture, each substance keeps its own properties?”

$200 Answer - Mixtures and Solutions

It means that the physical properties of the substances have not changed. For example, in the trail mix mixture, the substances have not changed their shape, size, color, taste, etc. Since the substances have kept their originalproperties, the mixture can be separated back into its original, separate substances.

$300 Question - Mixtures and Solutions

Additional Questions:

A solution has two parts: a solute and a solvent. In a sugar water

solution, which is the solute and which is the solvent.

$300 Answer - Mixtures and Solutions

C – the sugar dissolves in the water, and you

cannot see it.

The sugar is the solute. The water is the solvent.

$400 Question - Mixtures and Solutions

$400 Answer - Mixtures and Solutions

A – add more salt.

The more solute a solution has, the more

concentrated it is. Adding more solvent would lower the concentration of the

solution.

$500 Question - Mixtures and Solutions

$500 Answer - Mixtures and Solutions

B – cold tea has a lower rate of dissolving than hot tea.

In general, the hotter the liquid (solvent), the faster it can dissolve a solid (solute).

$100 Question – Separating Mixtures

$100 Answer - Separating Mixtures

D – sand and rocks.

A strainer would work well because the sand androcks are different sizes. The sand would pass through the holes in the strainer while the rocksstayed on top.

$200 Question - Separating Mixtures

$200 Answer - Separating Mixtures

A – floatation.

Once the oil floats to the surface of the water, itcan then be skimmed off the top using a filterwhich captures the oil while allowing the waterto pass through.

$300 Question - Separating Mixtures

When is it a goodtime to use magnetism to separate a mixture?Give an example.

$300 Answer - Separating Mixtures

When the mixture contains some substances that are magnetic and some that are not. An example would be a bucket of nails and screws that are mixed with wood, plastic pieces, dirt, etc. A magnet could quickly get the nails and screws separated from the other materials.

$400 Question - Separating Mixtures

When would be a good timeto use filtrationto separate a mixture? Give an example.

$400 Answer - Separating Mixtures

A good time to use the process of filtration to separate a mixture would be when the mixture contains solids that have different particle sizes. For example, a mixture of flour, salt, and watercould be passed through filter paper to removethe flour. The salt and water would pass throughthe filter and captured in a cup, where it could be separated through evaporation.

$500 Question - Separating Mixtures

$500 Answer - Separating Mixtures

D – separate solutes in a solution.

$100 Question – Wild Card

$100 Answer – Wild card

A – harmful gases are released into the air.

$200 Question – Wild card

What type of change have the objects in the pictures above gone through? How can you tell?

$200 Answer – Wild card

Chemical change. You can tell because in

each instance, a new substance was formed

(ashes, rust, etc.)

$300 Question – Wild card

$300 Answer – Wild Card

A – decreasing the temperature.

This would have the opposite affect of slowing down (decreasing) the rate of dissolving.

$400 Question – Wild card

$400 Answer – Wild Card

C – biodegradable materials.

Biodegradable means that the materials are ableto break down safely into the earth.

$500 Question – Wild card

$500 Answer – Wild card

H – sometimes.

Some mixtures are solutions, but not all. A mixture is only a solution if one substance dissolves in the other (a solute and a solvent).

Final Jeopardy

A teacher mixed a solid with a liquid. A cloudof white gas formed. What most likely happened? What evidence do you have to help you draw this conclusion?

Final Jeopardy AnswerA chemical change has occurred. You can tell because a new substance (a white cloudof gas) was formed. The original mixture didnot contain a gas, only a solid and a liquid.
