What is MATTER?

100
Is a melted popsicle an example of a physical change?
What is YES? You can melt and refreeze a popsicle and it will still be a popsicle.
100
Is rust an example of a chemical change?
What is YES? You cannot change rust back into the metal is was before; therefore, it is a chemical change.

You use these to help you identify the physical properties.
What are YOUR SENSES?
200

These properties are reversable.

What are PHYSICAL PROPERTIES?

200
Is Alka-Seltzer and water an example of a physical change?
What is NO? When you mix Alka-Seltzer and water, bubbles form, which indicates a chemical change as taken place.
200
Name the two indicators of a chemical change.
What are color change, bubbles, temperature change?
200

What is the temperature at which a solid turns into a liquid called?

What is melting point?

200
Name 2 physical properties of ice.
What are cold, hard, solid, wet, etc.?
300
Type of change where a new substance is created.
What is a CHEMICAL CHANGE?
300

Name a way that you can speed up dissolving a solute in a solvent.

Mixing it or heating the solvent

300
Name a food that is an example of a chemical change and explain why.
What is a cake, because you cannot turn a cake back into the eggs, flour, sugar, etc. that you mixed together?
300

These molecules can move freely and will take the shape of any container you put them in.

What is a LIQUID?

300
Name 2 physical properties of water.
What is liquid, wet, odorless, etc.
400

A type of change where the size and shape may change but the substance does not.

What is a PHYSICAL CHANGE?

400
Explain how water could be an example of a physical change.
What is freezing and melting water to and from ice is an example of a physical change?
400
True or False. Turning peanuts to peanut butter is an chemical change.
What is FALSE? To make peanut butter, you grind up roasted peanuts, so nothing new is being created.
400
These molecules move rapidly and freely whereever there is open space.
What is a GAS?
400
Explain how iron fillings and sand can be separated using physical properties.
What is iron is magnetic and sand is not, so you can use a magnetic wand to separate the two substances?
500
This type of matter keeps a definite shape.
What is a SOLID?
500

Double Jeopardy: Explain how the water cycle an example of a physical change.

Water changes from a liquid/solid when it precipitates, to a gas when it evaporates, then forms back into a liquid when it condensates. Then the process repeats again with the same substance, WATER!

Double Jeopardy: Explain how a rocket launch is an example of a chemical change.

What is the fuel combines with another chemcial to produce large volumes of a hot gas that propel the rocket into space?

500

How can you prove that gas has mass?

the balloon experiment, collecting the gasses from an experiment and then removing the collected gasses will cause it to decrease in weight, baking soda and vinegar experiment, etc.
