Hard to believe we have completed 4 weeks of chemistry. Great work guys!! I hope you are amazed at the intricacy with which our Heavenly Father made the earth. To think of the exactness of each atom and how they work together and make up everything around us. We should stand amazed and in awe of His awesome creation!!
HOMEWORK:
Monday: Complete pg 27 Suds Duds experiment (sent home plaster of paris)
Tuesday: Silly Putty-with the silly putty we made in class or some you have at home perform the following and record your results. (If your putty has been destroyed then do not worry about completing this DO NOT FEEL LIKE YOU MUST GO OUT AND BUY SILLY PUTTY)
1. Place in fridge for 10 minutes. Drop from 30 cm and record how high it bounces.
2. Place 6 inches from a light bulb for 5 minutes (remember keep away from fabric and carpet) Recheck bounce height.
Wednesday/Thursday: Research the source, composition and properties of asbestos.
1. What properties made it suitable for construction in the past?
2. How did these same properties cause asbestos to become a health hazard.
3. What is being done to eliminate the hazard?
4. What substances do they use nowadays to replace asbestos?
Class Re-Cap:
We began class by making silly putty. Another colloidal substance. We let it sit while we took the quiz, went over homework, and defined the last few groups of the periodic table. We also focused on the differences between metals and non-metals. We then experimented with our silly putty (which did not turn out very good-yet it still bounced but lacked the stretchability which is characteristic of silly putty). We pack alot into 1 hour and 15 minutes. My hope is that each student is seeing the magnificence of God's intricate creation.

Why do we salt icy roads?
HOMEWORK:
Monday: finish worksheet page 44 & complete page 46
Tuesday: Research the German passenger airship the Hindenburg. Write a paragraph and include the following:
1. What kind of gas was the ship made of.
2. What happened to the ship. Why?
3. What kind of gas is used today in blimps?
Wednesday/Thursday: Make a "periodic table" of the fruits listed below. Use the characteristics of the fruits to organize them into rows and columns. After your table is complete, write a brief explanation telling how it is organized.
lemon, grape, pear, plum, grapefruit, cherry, banana, coconut, watermelon, honeydew melon, mango, raspberry, blueberry, apple, avocado, tangerine, orange, clementine, strawberry, nectarine, peach, lime, and cranberry
Class synopsis:
We discussed the purpose of the periodic table. The reason for the organization was explained we then began to dig into each group. The first group is the alkali metals. This group is very unstable. Sodium (Na) is located in this group. We talked how salt (NaCl) is used to lower the freezing point of water. During lab time we measured the temperature of water and watched the temperature lower as we added salt. Then we hypothesised what would happen if we added different substances. Great time to apply all the salt on the roads!!

Periodic Table
Tomorrow be ready to dive into the periodic table. Why is it arranged the way it is??? Looking forward to seeing each of you tomorrow. Be ready for quiz-elements:)

What does the size of a football field have to do with an electron cloud?
HOMEWORK
Monday: worksheet page 43
Tuesday: Display sample or pictures of 5 elements of your choice. You may display them on paper or poster board whichever you prefer. Include the name, symbol, atomic number, atomic mass, and use for each element.
Wednesday: worksheet page 42
Thursday: Draw a Bohr model (we did these in class with the construction paper and JUJUBES) of Aluminum and Fluorine.
Recap of class:
This week we introduced the Periodic Table of the Elements. We discussed the basic unit of each element the ATOM. We discussed the composition of the atom (proton, neutron, and electron) and the models of the atom. We then attempted to build models of atoms out of construction paper and JUJUBES using the atomic number of the atom. It was exciting as light bulbs slowly went on as we were doing this activity. Enjoy the study of ELEMENTS. It is amazing to think how intricate everything is that the Lord has made. Rejoice and be glad!!

What's the MATTER??
HOMEWORK: **Thursday you need a box of cornstarch**
Monday: Finish worksheets pages 35, 36, and 38
Tuesday: 1.write out an acronym for chemistry (I described how to do this in class but please call if there are further questions)
2. Look in your refrigerator and identify 7 items as elements, compounds, or mixtures
Wednesday: List 5 physical changes and 5 chemical changes
Thursday: Make Oobleck and write down a 5 sentence description of this amazing substance. Please include how you would label this? element, compound, solution, colloid, or suspension
(Parents if you would rather not go down this road that is fine)
recipe oobleck: 1 box cornstarch and 1 1/2 cup water (maybe a little less), mix the cornstarch into the water gradually. Mixture will become lumpy and hard to stir. Check consistency. Oobleck should flow when you tip the bowl, but feel solid when hit or rubbed across the surface. You can store in air-tight container for a few days or discard.
Synopsis of class:
Matter is what we discussed!! The basis of chemistry is the study of the composition, behavior, structures, and properties of MATTER and changes they go through. Chemistry is everywhere happening all around us and in us:) We discussed how matter is divided into substances and mixtures. We talked about the three types of mixtures (solution, colloid, and suspensions). We ended by talking about describing matter physically and chemically. After our discussion we broke up into lab groups and observed a chemical change and measured water and rubbing alcohol to show how the molecules compress.
