Traveling through the States of Matter RAFT and MODEL

DUE: A DAY Weds Jan 30
B DAY Thurs Jan 31

Remember this is NOT an essay. It is a creative writing assignment in the format of a postcard! Have fun and use you're creativity in the postcard and Model...just remember that your information should have accurate science content!

R.ole-A particle of Matter
A.udience- matter that has never experienced a change in state
F.ormat- A postcard about your travels
T.opic- Discuss your travels through the 4 states of matter. Be sure to include the following:
-How particles move and behave in each state
- How they change through the 4 states
-At least two characteristics of each state


To further illustrate your travels you will Create a 2-D model of the particles in the 4 states of matter out of torn pieces of construction paper. In your model I must be able to tell that you understand how the particles in each state move and behave

-Make sure you choose one sheet of Black Paper,1 Piece of colored paper,4 small squares of white paper from the supplies in the classroom.

Use your notes and the test book to help you!
***To re-read the info on Plasma you can visit: http://www.chem4kids.com/files/matter_plasma.html***

RAFT: 15 points
Must include all 4 states of matter
Explain how particles move and relate to one another

Lab Stations--Questions

Below I have posted each procedure with all guiding questions from our Lab today. Please check to make sure you have answered all questions completely and provided evidence when necessary. Make sure that you following proper graphing procedures for lab station number 2!! (use a ruler, pencil and graph paper, label all axis and give your graph a title)

Station 1--How Much Mass??

In this lab, you will compare the mass, volume, and type of matter in a variety of objects.

Materials List:
• balance
• balloon, small
• golf ball
• handball
• marshmallow
• pumice stone
• rock
• various other
objects

PROCEDURE
1. Do not touch the objects your teacher provides. Write down your observations about each object.
2. Based on your observations, list the objects in order from least mass to greatest mass.
3. Pick up each object, one at a time. Write your observations about the mass of each object .
4. Based on your observations from Step 3, create a new list of the objects in order from least mass to greatest mass.
5. Use the balance to measure and record the mass of each object to the nearest 0.1gram. Record the mass of each object.
6. Based on your measurements from Step 5, create a new list of the objects in order from least mass to greatest mass.
7. What information did you use to decide what the order of the objects should be in Step 2?
8. Why was it difficult to determine the object’s mass based on visual observations alone?
9. In what way did your original list change after you were allowed to hold the objects?

10. How did your list change after you actually measured the mass of each object? Were you surprised by any of the results?


Station 2—Comparing Mass and Weight


In this lab, you will compare the mass and weight of five different objects using a balance and a spring scale.

MATERIALS
For each group
• balance
• graph paper
• small objects (5)
• spring scale

PROCEDURE
1. Create a data table like the one below in your notes.

2. Using a triple-beam or electronic balance, measure the masses of five small objects. Record the masses in grams in your data table.
3. Using a spring scale, find the weights of the same five objects. Record the weights in consistent units.
4. On a piece of graph paper, make a graph of weight versus mass using your five objects. (x axis—mass; y axis—weight) In the space below, write a sentence that describes the relationship between weight and mass.
5. Gravity is a force of attraction between Earth and all other objects. What was stopping the objects from being pulled to the ground as you measured them?


Station 3—Investigating Irregular Solids!

In this lab, you will determine the volume of an irregularly shaped object and then calculate it’s density using the formula D=m/v.

MATERIALS
• graduated cylinder
• various objects, solid
• water
• Balance

PROCEDURE
1. Make a data table on your paper, like the one below, to record your data in your notes
2. Find the mass of one of the small object using an electronic balance and record it in your data table. Be sure to include your unit of measurement.
3. Fill a 100 mL graduated cylinder to about the 50 mL mark with water. Read the volume at the meniscus, and record your reading.
4. Tip the graduated cylinder, and slide a solid metal object into the cylinder.
5. Carefully read the new level of water in the graduated cylinder, and record your results.
6. Subtract your first measurement from the second measurement to determine the objects volume. Use cubic centimeters as your unit of measurement. how your work.
7. Now calculate the density of your object using the formula D=m/v.
Show your work and be sure to use the appropriate unit of measurement.

Complete steps 1-7 for all of the objects at station 3


Station 4—Sink or Float??


In this lab, you will calculate the densities of several objects. You will then use a tub of water to determine how each objects density relates to its ability or inability to float in water.

Materials
• Balance
• Ruler
• Plastic tub
• Water
• Various regular solids

PROCEDURE:
1. On your paper construct a data table like the one below.
2. Select one regular solid and record its identity in the table.
3. Make a prediction as to whether or not you think this object will sink or float in the tub of water. Record your prediction in the data table. Do this for each object at your station
4. Use your ruler and balance to determine the objects mass and volume (remember v=lwh. Do this for each object at your station
5. Calculate the density of the object using the data that you have collected. Remember d=m/v. Do this for each object at your station.
6. Place the object in the tub of water gently. Record your observations. Do this for each object at your station.
7. The density of water is 1 g/cm3. Examine your data. Which if any, of your objects are denser than water. Which objects are less dense than water.
8. Based on your results, how can you use densities to predict whether an object will sink or float in a given liquid?
9. CONNECTION TO SPACE UNIT!!! What do you remember about the density differences between terrestrial planets and gas giants. Now that you have explored the densities of different objects can you make a connection between the composition of terrestrial planets/gas giants and their densities? Explain.

VOCAB NOTE CARDS!!!

Note Card Amnesty!!!
If you received a zero on the last Vocab check in for LT's 7, 8, and 9 you may complete them all according to my classroom expectations, show them to me next class period and receive full credit.


Potential Extra credit~~~
Please remember that you should have all of your Vocab note cards, from the beginning of the year until now, with you in class every time I see you! Our note cards are an incredibly important tool as we begin our push toward FCAT in April. All cards should be completed accurately, with care for content and neatness, according to the class expectations. (Please review the template in my classroom if you are unsure what those are.) In the next two weeks I will be randomly asking classes to take out their note cards to play some review games. Any students who have all cards completed as stated above and in some sort of protector/zip lock baggie/box or on a binder ring in class will receive 10 points extra credit in my 3rd quarter grade book!!!!

Homework for LT#8 Our Solar System

Periods 1A and 4A due Thurs
Periods 6B and 7B due Weds


Please read Unit 3 lesson 4 "The Terrestrial Planets" and Lesson 5 "The Gas Giants." create a characteristics flip chart like the one Mrs. Wilhelm has on the board. If you need to take a look at it, it is still hanging on my board. Please note down the important characteristics for each of the 8 planets as you read the lessons. Be prepared to use these notes to help you and your table edit your Terrestrial vs. Gas giants T-Chart in class.
