HOMEWORK:
Monday/Tuesday: Create a crossword puzzle with 25 words from this semester.
Wednesday: Make a Bohr Model of the following elements: Al, Ca, C, O (Remember Week 2 we did these with JuJu Be candy)
Thursday: Study for a 10 point quiz and bring in your favorite food (FRIDAY) for scientific testing!!
CLASS RECAP: We introduced acids and bases. We were able to complete a couple of experiments using acids and bases and litmus paper-our red cabbage indicator did not work as well as I would have liked.
For our last class we will be doing a review quiz (10 pts). We will also test some of our favorite foods. We have a shortened class Friday because of the open house-Look forward to seeing parents during this time.
Have a superb week!!

Homework #2!!
Thanks for the prayers! It was a good time to be with family.
Now to the homework:
Monday: Enjoy the warmer weather!!
Tuesday: Define acid, base and pH scale. Give 5 examples of an acid and 5 examples of a base found in your house.
Wednesday: On Friday we reacted sugar with sulfuric acid in order to extract the carbon from the sugar.
1. Was this an exothermic reaction or an endothermic reaction?
2. What is the difference between the two?
3. If you wanted to develop a product for warming people's hands at outdoor winter events would you choose and exothermic reaction or an endothermic reaction to use? Why?
Thursday: Study for the quiz. Complete the following two labs. Record your results on paper and we will discuss in class.
Baking soda and baking powder: What's the difference?
1. Place a teaspoon of baking soda and baking powder in separate cups.
2. Add a tablespoon of water to each. Observe. Which substance fizzes?
3. Add a few drops of vinegar to the substance that did not fizz. Observe.
Coagulation of Milk
1. Fill a cup halfway with milk.
2. Add to the mild a half-cup of vinegar.
3. Slowly pour into another cup to observe. Record your results.
Thanks guys for your patience. If you would please keep my son in your prayers tomorrow (Tuesday) he is having tonsils, adenoids removed and ear tubes in [Shelby I know you can relate:)] Have a great week!!

Homework
Hey guys-
I am out of town this weekend and I will not be able to post homework until sometime on Monday. My grandfather passed away this past week and we are with family in Detroit. Give your family a hug and enjoy each moment you have together.

HOMEWORK
Homework:
Monday: Design an experiment with the following question-
Which type of sugar will dissolve the fastest in water : powdered, granulated or cubed?
Remember the steps to the scientific method?
problem/question
research
hypothesis
experiment
organize/analyze data
conclusion
I would like you to complete the 1st 4 steps without actually doing the experiment at home. We will complete the experiment in class. I would like you to state the question (already given to you), research (if needed), state your hypothesis (in a complete sentence), and design the experiment. In designing the experiment remember to list the control, constant, independent variable and dependent variable (reach into your brains from the beginning of 1st semester)
Tuesday: Next week we are going to discuss solutions. I would like you to define the following words for me: desalination, saturated solution, solution, solubility, solute, solvent, unsaturated solution
Wednesday: Next week we are going to discuss solutions. The world's largest solution is -THE OCEAN!! I would like you to research what is in the ocean. List six elements that are found in the ocean water and give the percentage of each (wikipedia had a great resource for this).
Thursday: Try to balance a couple of the chemical formulas from the worksheet I gave you. If you are stumped don't worry we will work on this in class. Figure out as many as you can. [This is the worksheet I gave you and said it wouldn't be homework:)] I do not want to introduce anything else new so try this worksheet-if it overwhelms you please just study for the quiz (we will quiz over the homework you did!!)
CLASS RECAP: We were able to finish our lab work!!! I attempted an experiment outside which flopped-will try again next week!! Completed a couple of balancing equations took a quiz and collected tests and homework. Time flies when your having fun!!
Have a wonderful sunny day-Mrs. Tyler
