Chemistry

Welcome Back!

How do scientists design and conduct investigations?
August 16- Complete writing questions that you could investigate about M&Ms. List the variables on p. 28 of your handout.

August 22- Study vocabulary words using Quizlet. [|Quizlet link]

Use this link to learn about water and its properties [|Chemistry Review Water]

September 4- Study for the quiz on dissolving for Tuesday. Have you checked quizlet and your notes? Make sure you how the vocabulary words are used.

September 12- Make sure that you have completed the data table and graph on the relationship between the temperature of water and the dissolve time for a M&M. Use your handout for how to make a data table and graph and check your work before class. Use the Create a graph- Kid Zone to make the graph.

Here is [|Create a graph- Kid zone]

You'll submit your work on Wednesday in class.



The data: Tomatoes were grown at various temperatures. The number of tomatoes that grew on each plant were counted.
8 degrees C- 4 tomatoes, 12 degrees C- 10 tomatoes, 16 degrees C- 14, 18 degrees C- 18 tomatoes, 22 degrees C- 24 tomatoes, 24 degrees C- 16 tomatoes

Design Your Own Investigation
September 26- Bring in supplies for your investigation. You answer your own question in the investigation.

September 28- Here is the example of a conclusion that we wrote in class. Use it and the checklist to check the quality of your conclusion and lab report. Have your lab report and checklist ready when you come to class on Sunday.

October 17- Review the tests we did on crystals: appearance, crushability, solubility, and recrystallization. Your summative assessments are 1) on your ability to conduct those tests and make observations and, 2) to plan an investigation to measure the absorbancy of sodium chloride vs. potassium chloride.

October 19- Conduct 4 tests to compare and contrast sodium chloride and potassium chloride. Refer to this rubric for the specifics.

October 23- Complete your compare and contrast study for NaCl and KCl. Get ready to submit it on Moodle during the next class. You will have to write the final summary paragraph before submitting it. Use the rubric above to check your assignment for its quality.

October 26- Submit your tests and paragraph on Moodle if you haven't done so already.

It's time to design an investigation to determine if sodium chloride and potassium chloride are absorbed the same way. 1) What research do you need to do before you begin? Do you know what absorption is? How are substances absorbed? Write down the results of your research with the sources. (In a blog?) 2) How can we measure absorption? Write down 3 ways we can measure absorption. Try measuring absorbency with the supplies in class. Play around to determine the best way for measuring absorbency. Write what you did and evaluate each method you used. Which is the best one or two that you will use? Explain why you picked them.

Here is a design rubric for you to use.

October 30- Plan and conduct the investigation today! The completed lab must be turned in this week. (Block D special attention!)

November 15- Atoms!! Here is a viewing guide to complete during the video.

What happens when matter is warmed or cooled?
November 17- Atom exploration. Check out dihydrogen monoxide. Answer the questions in a file and then upload them to Moodle.

Here is the acrostic if you want to do it for fun!

What are the properties of matter?
November 28- We're virtual! Today is Virtual School Day. Open these files. Complete the work on the file and then submit them on Moodle. Having problems knowing what to do? Use your strategies! Read it again, read it out loud... I look forward to receiving your assignments on time. Have fun!

1) Open this file first-- the Matter webquest-- and follow the instructions. It is a review of the 5 states of matter. Submit it on Moodle.

2) Open this file-- the states of matter analogies-- and write your own analogies. Submit it on Moodle. This is a summative assessment. You're done.

November 30- There will be a quiz on Sunday about Matter. Here is a quizlet link to help you review. [|Matter Grade 7 CAC] Review the concepts we have studied by using your pink booklet.
