States of Matter
This state of matter holds its shape unless a force is applied, and its atoms are packed tightly together.
A solid
Is the following a form of matter? If so, is it a solid, liquid or gas?
- A mushroom
A solid.
Maya leaves a giant ice pop on her warm backyard patio table on a sunny afternoon. An hour later, she returns to find a sticky pool of flavoured liquid where her treat used to be. Which change in state occurred?
Melting
An educated guess or predication made before conducting an experiment.
Hypothesis
Dry ice is a solid form of this common gas that humans breathe out.
Carbon Dioxide.
This state of matter expands to fit the volume of its container, with particles moving freely at high speeds.
Gas
Is the following a form of matter? If so, is it a solid, liquid or gas?
- Blood
After a heavy autumn rainstorm, Leo watches large puddles form on the playground. Over the next three warm days under the sun, the water level slowly drops until the pavement is completely dry.
Evaporation
This process involves carefully recording what you see, notice, or measure during an experiment.
The temperature that my pot of water will begin to boil at.
100 degrees celsius - boiling point.
This state of matter has no fixed shape, can flow, and takes the shape of its container.
Liquid
Is the following a form of matter? If so, is it a solid, liquid or gas?
- A shadow
Not a form of matter.
Daniel steps inside the school during a cold December morning and within a couple of seconds a thick layer of tiny water droplets fogs up and coats his pair of glasses.
Condensation
During the ice cream lab, this substance was added to the ice to lower the freezing point of water.
Salt
Draw the particles of a gas.
- Wild and free, lots of space, movement (arrows).
Every solid, liquid and gas is made up of these tiny particles that can only be seen with a very strong microscope.
Atoms
Is the following a form of matter? If so, is it a solid, liquid or gas?
- Toothpaste
- Acceptable answers: Solid, liquid, or non-newtonian fluid.
Mr. MacGregor loves all things spooky! To celebrate Halloween he decides to go to all the haunted houses he can find. One in particular was especially scary; the whole house was covered in a thick white fog that made everything hard to see.
Sublimation.
During the ice cream lab, this type of energy moves out of the liquid cream mixture and into the cold ice-and-salt mixture.
Dry ice is extremely cold and undergoes sublimation at this exact temperature on Earth.
-78.5 degrees celsius.
Mass (or weight) and volume (or takes up space).
Heat, sound waves and electricity are NOT examples of matter. What are these actually examples of?
Energy.
Mrs. Gohl looks out the window one crisp November morning. She notices a shimmering white blanker of delicate ice crystals covering the grass.
Deposition
Why did we shake the bag during the ice cream experiment?
In Canada, frost is more likely to form on the ground in the fall rather than the winter. Why do you think this is?
Frost is more likely to form in the fall because there is still warm, moist air from the daytime during the fall compared to the daytime temperature in the winter.
