liquid

200

Which state of matter has particles that are the most spread out and that move quickly in all directions?

A) Solid 

B) Liquid 

C) Gas

gas

300

Which state of matter DOES NOT change shape and DOES NOT change volume

Solid

400

Come up to the board and draw particle diagrams of the three states of matter. Label the state below the picture.

Teacher will evaluate 

500

What is the name of the space where there are no particles? This place contains nothing.

A vacuum

Changes of State

100

When ice turns to water, it...

A) Evaporates 

B) Freezes 

C) Melts

C) Melts 

200

Which change of state happens when matter loses heat?

A) melting 

B) freezing 

C) evaporation

B) freezing 

300

I boiled water last night to cook noodles. I left the pot on the stove too long and all of the water disappeared. What happened to the water? 

A) It evaporated 

B) It condensed 

C) It was stolen by Kevin

A) It evaporated 

400

Which change of state causes water bottles to become wet on the outside when it's humid outside? 

A) Freezing 

B) Evaporation 

C) Condensation 

D) Melting

C) Condensation

500

Come up to the board and draw a diagram showing the 4 changes of state we learned. Use red to show heat is added. Use blue to show heat is lost. Include the following vocabulary: 

-solid -liquid -gas 

-melting - freezing -evaporation -condensation 

This is worth a total of 800 points if done perfectly. Teacher will give a score based on accuracy and completion.

Water Cycle

100

This is the process where water changes from a liquid to a gas (water vapor) due to heat from the sun. 

A) Precipitation 

B) Evaporation 

C) Condensation 

B) Evaporation 

200

Complete the blank: When a lot of water has _____, the water droplets in the clouds become too heavy for the air to hold them. 

A) condensed 

B) evaporated 

C) frozen

A) condensed. 

Condensation is the step in the water cycle that causes clouds to form and release water.

300

Which one is NOT a form of precipitation? 

A) Ice 

B) Hail 

C) Rain 

D) Ash

D) Ash

400

What is the correct order of the water cycle? 

A) Collection-Evaporation-Precipitation-Condensation 

B) Evaporation-Precipitation-Condensation-Collection 

C) Collection-Precipitation-Condensation-Evaporation 

D) Evaporation-Condensation-Precipitation- Collection

D) Evaporation-Condensation-Precipitation- Collection

500

Name and define the last state of the water cycle.

Collection

This is the final step where water collects in rivers, lakes, oceans, or seeps into the ground

Atoms, Elements, Compounds

100

The smallest pieces of matter are...

A) atoms

B) compounds 

C) mixtures

A) atoms

200

A substance made of just one kind of atom is called an...

A) compound 

B) element 

C) mixture 

B) element 

300

Air is an example of a...

A) element 

B) compound 

C) atom 

D) mixture

D) Mixture 

Air is a mixture of several different elements and compounds. Air contains nitrogen, oxygen, carbon dioxide, water vapour, and small quantities of other gases. 

Bonus question worth 400 points- Air is a mixture because the amount of elements and compounds inside of it can change over time and change depending on location. How do you think the composition of air has changed since 1950?

400

Say if its an element or compound. 100-400 points 

1) K 

2) CaO 

3) Iron 

4) Iron Sulfide

Elements- K and Iron 

Compounds- CaO and Iron Sulfide

500
