This is a unit designed for Chemistry grade recovery through a 10 step sequence

................................. __THAT MUST BE COMPLETED IN THE SCIENCE RESOURCE INDEPENDENTLY__.
=__Introduction:__= Listen to the following podcast regarding procedure and time constraints for this enhancement program. It resources multimedia to force more independence in the student. The understanding is that once successfully completed the student will earn a final grade change to a C each semester of Chemistry. There is no partial completion modification. This is the offer available to students with a final grade between 50% and 69% in chemistry. Any student earning final percent under 50% must retake the instructional classroom course offering. __Summary of program components:__

media type="file" key="chemistry grade recovery.mp3" 1. [|www.chemthink.com] : Sign on as a new student under the class **"Credit Recovery"...**you must get a current code from the instructor because each code expires bimonthly. You must complete the following seven selections of chemthink (highlighted and underlined in bold under the headings listed): -Introduction -The Atom __-Ions__ __-Isotopes__** -Ionic Bonding -__Ionic Formulas__** -Covalent Bonding To be complete, you must a. read and submit a 10 fact summary of the tutorial b. pass the question set successfully.
 * -__Particulate Nature of Matter__**
 * -__Atomic Structure__
 * -__Ionic Bonding__
 * -__Covalent Bonding__**
 * __*You must get this work to the instructor for grading...__DO NOT LEAVE IT IN THE RESOURCE ASSUMING SOMEONE WILL CHECK THE FOLDER FOR COMPLETED WORK......

2. Upload the notebook file " Balanced Equations" and __run a hard copy__ **of what you have workout as correct compounds, because the program is locked and will not allow you to save your answers on the jump drive. The jump in the binder has the file on it. The computers in A219, C220 and C202 have notebook/ smartboard software on them. Submit to instructor as a unit #1 review. After review is graded and returned, take quiz on naming and writing compounds passed with at least 75%, (or retaken). The quiz will be placed in the folder WITH YOUR NAME ON IT, once the review is graded.

3. Sign-on to chemthink again and complete the section on** -Chemical Reactions __-Chemical Reactions__
 * Upload the following powerpoint and turn in completed reactions to the grading instructor. The 9 reactions are all highlihgted in blue.



You can do these two assignments in either order.

4. There are three phases of matter that we study in chemistry. The first semester ended with a closer look at the unique properties of gases through the gas laws. Explain the difference between Boyle's Law, Charles' Law and GayLussac's Law in a three minute podcast to e-mail to your instructor's school account. You must reference a real life example of each law explaining the variable effects. For example: "Leaving a basketball outside in the winter exeplifies** Charles' Law **because a** decrease in the temperature **of the molecules resulted in a** decrease of the volume **they occupied inside the basketball.

Complete the** chemthink **lesson entitled:** -Gases -Behavior of gases
 * You do not have to write anything for the tutorial... just go through it... it is very interactive.

5. Reactions that occur in the forward direction at the same rate as the reverse direction are said to be in equilibrium at a specific temperature under similar pressure. Review the following powerpoint on equilibrium. Answer all parts of the four slides regarding questions on equilibrium. It addresses gases, as well as, liquids and solids.... it emphasizes the term solution, too.

6. Solutions are a unique form of an equilibrium system. They are the one form of matter classified as mixtures, yet they are homogeneous. The combination of two solution mixtures that results in a chemical change evidenced by a precipitate solid formation are able to be predicted by the Ksp value - again based on temperature. Complete the c**__hemthink__ **section: -**Lab -Chemical Reactions -Precipitate reactions Review the powerpoint entitled** 'Solubility' **that has the answers in the slideshow. It is a wonderful resource to go through, to that you can complete the next requirement. There is nothing to turn in....just work through the powerpoint.
 * Again, you do not need to write anything special for the tutorial.

There is another powerpoint //__you must complete__// on solutions. It is entitled** 'Ksp - questions only'**. After you turn in some work to the grading instructor with an attempt at all five questions, you will be given a file with all the answers to the questions/ problems.

7. Heat is a form of energy measured in calories or joules. Temperature is a measure of the average kinetic energy of a system. To measure the change in heat that occurs in chemical or physical change, the formula (change in) Heat = mass x specific heat x change in temperature. The lab for this section supports the law that the heat gained by one system is equal to the heat lost by another. You will be making a video podcast of your results in a lab experiment finding the specific heat of an unknown metal. Follow the same lab and format of the one we did in class with lead.

You will need to go through the powerpoint: 'Thermochemistry'. It will be a helpful guide....take notes. There is a worksheet on Heat loss-gain problems and Hess' Law. After the instructor goes over it, you can correct it with the answer key.

8. There is a review in the folder with One of each of the following problems: - Calculating the Ksp for a reaction to identify if a ppt will form - Calculating the Keq for a system and identifying what will happen if the system is stressed in a variety of ways. - Calculating the heat for a system during a physical change -Calculating the specific heat of an unknown substance -Calculating the total heat for a reaction using Hess' Law The final answer to each problem is provided, so you must show work to prove it. This worksheet must be completed, turned into the grading instructor, corrected and returned to you - the student. These problems involve completing and balancing equations using some basic chemistry problem solving skills. THE WORKSHEET IS NOT POSTED HERE BECAUSE IT MUST BE COMPLETED IN THE RESOURCE CENTER. There is a line for the supervising teacher to sign acknowledging that the work was done at school.

9. There is a second review with one each of the same types of problems again. This must be completed...IN THE RESOURCE CENTER..., handed to the grading instructor, corrected and returned to the instructor if any mistakes were made. The answers will not be provided until after corrections were made. This all must be done before you work the final quiz.

10. Final quiz saved to the 70th percentile or else retaken until that goal is obtained. It will be placed in the Chemistry Recovery Binder once the review is done.
