Frazil Ice
100

The three states of matter

Solid, liquid and gas

100

What is the difference between a chemical change and a  physical change?

A physical change the substance changes shape, but remains the same

A chemical change the substance becomes something new

100

Element

100

What is the difference between homogenous and hetereogenous?

Homogenous means it stays the same

Heterogenous means it changes or is different

100

What states of matter are in Frazil Ice?

Solid and Liquid

200

Name all four phase changes

Melting, Freezing, Evaporation and Condensation

200

Chemical or Physical Change?


200


Mixture of Elements

200

What does the fixed point on the graph represent?

Stays the same, does not change

200

What changes are happening in Frazil Ice?

Solid ice is moving on active water

300

How are solids DIFFERENT from liquids?

Solids vibrate in place and are slow

Liquids slide past each other and are medium

300

Chemical or physical change?


300

True or False:

A single element can be a compound

EXPLAIN WHY

False:A compound contains 2 or more elements that are bonded together

300

True or False: Solids move slowly and change their position

False: They do not change their position

300

Name an example of an element, compound or mixture in Frazil Ice

Hydrogen

Oxygen

H20

400

Why are solids characterized as moving the least?

Solids are low in energy and temperature which causes them to be slow moving
400

Provide an example of a physical and chemical change

Up to teacher if correct

400

How is Frazil Ice an example of a compound?

Contains both hydrogen and oxygen in the ice which are two different elements


400

What is melting point?

the point at which the solid turns into a liquid is melting 

400

Pick one question on our chart and answer it with your team

Up to teacher if correct

500

How does temperature affect the speed of a particle?

Adding heat speeds the particles up

Removing heat slows the particles down

500

Name an example of a physical or chemical change in Frazil Ice

Up to teacher disgression

500

How can Frazil Ice have both melting and freezing occurring?

Melting- water is moving downstream, heat is added

Freezing- ice blocks are on top of river, water was frozen into a solid

500

Why must we include at least 2 pieces of evidence in our written responses?

To provide clear data that supports our claim
