9/8 Classwork

Objective: Compare and contrast phases of matter and phase changes using an online simulation and real life demonstrations.

A.  Click this link.

B. Click states.

C. Click solid on the right side of the page and look at the particles.

1

Describe how the solid particles look. Explain at least two observations.

D.  Click liquid on the right side of the page and look at the particles

1

Describe how the liquid particles look. Explain at least two observations.

E. Click gas on the right side of the page and look at the particles.

1

Describe how the gas particles look. Explain at least two observations.

1

How are gases different than liquids? Use full sentences.

1

How are solids different than liquids? Use full sentences.

G. Click on phase changes at the very bottom of the page on the white bar.

1

What phase of matter is on the screen currently?

1

Play with the different features on the screen such as the finger, the heat/cool, and the air pump. Name at least two ways you can change the phase of matter on the screen to a different phase of matter, explain in full sentences.

RAISE YOUR HAND WHEN YOU HAVE COMPLETED 1-7

*DRY ICE IS EXTREMELY COLD, IF YOU TOUCH IT, IT WILL BURN YOUR HAND.

1

What phase of matter does the dry ice start in?

1

When the dry ice is placed into a beaker of water, what happens to the dry ice?

1

When the dry is placed into a beaker of water with soap in it, what do you observe happening? Use specific phases of matter in your answer.

1

Why do you think its called dry ice?
