Process

__Process:__
You will be working in groups of three chemists. Your teacher will assign you to a group. Your goal is to create an Investigative Report regarding chemical and physical properties and changes. *Many of the forms in the report will need to be filled out by each chemist. However, there may be some forms which are filled out by the group. The steps will let you know what you will need to gather. **Read the directions carefully and make sure you are completing all the steps.**

As a group, take some time to brainstorm and record 3 or 4 changes that can instantly, daily, weekly, monthly, or yearly occur. Can you think of any changes that may occur over a long period of time? Use the brainstorm worksheet provided for the group and have one of the chemists be the recorder. *This brainstorm worksheet will be page 1 of your investigative report. Only one worksheet per group needs to be handed in with the Investigative Report.

Step 2:
Each group will divide the following links up so each chemist will look at two of the links below. The chemist will circle the websites on notes page to indicate which websites they are in charge of. Then, the chemist will take notes on the two websites they chose.

*When everyone in the group is done with their notes, the group will come up with a working definition for physical changes and a working definition for chemical changes. Each chemist will write the definitions the group came up with on their own sheet. Each sheet will be turned in with the final Investigative Report.

Chemists will use the above links plus the links provided in this step to create a list of clues that show chemical and physical changes have occurred on the T-chart organizer. *Each chemist will need to fill out one of these T-charts. All T-charts will be submitted with the Investigative Report.

Your team is now ready to try some experiments and test their knowledge of physical and chemical changes. Each person will get the lab sheet with two sides on it, Chemical Changes in a Bag, Part 1 and Part 2. Each person will need to fill out their own lab sheet but you can collaborate as a team to finish the lab. Move back to the lab stations and follow the directions on the sheet to complete the labs.

Please make sure you wear goggles, do not mix the spoons up and wash your hands after the lab!

*Once you have completed this, each person's lab sheet will be part of the Investigative Report.

Step 5:
Once your team has finished steps 1-4, you will need to __**see your teacher**__ to proceed to step 5. Click Here for Step 5 after teacher approval.

**If there is a substitute present please make sure your group gets the paperwork with your groups names on it. Your group only needs to complete the highlight examples, 3 out of 5 examples.
