Q3P1: CH.4 True and False
1. Use this CH.4 Notes Page (Click the link) to complete this True and False Google Form (Click the link).
IMPORTANT: LOOK UP THE ANSWERS! Don't just guess! You may work together on this.
Once you finish, make sure you look at the feedback provided in the google form to understand why you got the ones wrong you got wrong. Check in with Mrs. Roehm and let her know what your score was and ask her any questions you have.
Q3P2: Crack That Marble Labs
Read ALL of the directions before beginning.
1. In Google Classroom, open the assignment Q3P2: Crack That Marble Lab document.
2. You will be follow these lab directions to complete the stations. (Don't start yet! Read the tips below! (If you are absent, the lab document in Google Classroom has videos of all the labs you can watch.)
IMPORTANT:
- You will be completing the entire lab document before you check in. You don't have to check in after every lab station.
- You should do a lab station and then answer the questions for that station. You should NOT do all the labs and then all the questions.
- If a question asks about molecular motion, it is asking if the molecules sped up or slowed down.
- If a question asks about molecular arrangement, it is asking if the molecules spread apart or came closer together.
- If the question asks you about molecular motion AND arrangement, you have to talk about the speed of the molecules AND the spacing. Students often make the mistake of only talking about one or the other.
- Be careful in your answers when talking about how molecules respond to heat. Molecules don't "expand," the molecules SPREAD APART. The object expands, the molecules don't.
- These CH.4 Notes are a good resource if you get stuck on a question.
- Here is a link to the CCC page and the Sentence Starters if you need them for your discourse.
- Remember the tips that Mrs. Roehm went over in class. The slide she shared is shown below.

Q3P4: Separating Mixtures Labs
Read ALL of the directions before beginning.
​
​Goal: Separate a cup filled with sand, salt, iron filings, and marshmallows into 4 separate containers. The tools you may use are a magnet, trays, strainer, crucible, Bunsen burner, matches, goggles, water, beakers, ring stand, and a cup with holes in the bottom.
You must figure out how to do this on your own. If you have questions about the directions, ASK Mrs. Roehm for help clarifying. You MUST come tell me your plan before you can start separating the mixture.
(HINT: You MUST use all of the materials listed above in your procedure/plan). Once you have approval, separate your mixture into 4 separate containers.
Show Mrs. Roehm your four separated materials to earn your signature.

Q3P5: Crazy Colloid
Read all of the directions first and then ask Mrs. Roehm to make you some of the Crazy Colloid.
Once you have your colloid, try to do the following to determine if you feel that the colloid is a solid or a liquid.
1. While it is still in the cup, poke the colloid with one finger using a fast and hard motion.
2. While it is still in the cup, poke the colloid with one finger using a slow motion.
3. Pour it onto the table. (Yes, you can pour it right on the table.)
4. Try to make the substance into a ball.
5. Try to make it into a ball and bounce the ball.
6. Squeeze the colloid in your hand, then release the pressure.
7. Clean up your station!!!!
Assignment:
Now, you will have to answer the question "Is the Crazy Colloid a solid or a liquid?" (You may not say soquid or sliquid!)
On a piece of paper, make a T Chart to collect evidence about whether it is a liquid or solid. (You can use these notes if they help) You must connect all of your evidence to a CCC Bullet Point.
After you add all the evidence to your T Chart, next to each piece of evidence add a CCC bullet point that that piece of evidence connects to. By the end, you must at least 5 out of the 7 CCC's.
