 Science 8:  We completed section B of the Heat Lab, Radiation.  Due next class is your graph of Temperature vs Time for heating water by radiation.  We watched this clip to try to understand why it is colder in the winter.

Chemistry 12:  Today we reviewed the difference between the solubility and Ksp by going through Unit 3 # 67.  We looked at #67 on page 99 and I asked these questions:

1) T/F: the Ksp of Mn(IO3)2 is 4.78 x 10^-3.   (... times 10 to the power of negative 3)

2) Write the Ksp expression for Mn(IO3)2.

3) If you needed a bottle with Mn2+ ions from our lab, what compound would you search for?

4) Determine the concentration of each ion in 0.0200 M KIO3.

5) Determine the concentration of each ion in 0.00478 M Mn(IO3)2

We added Unit 3 # 64, 65, 67 and 68 onto Unit 3 # 56-63, then we did the WS titled Solubility Review.

Chemistry 11:  After completing the Balancing Minireview WS #2, we learned the principles of Stoichiometry (Read pgs 123 and 124).  Due next class is the Stoichiometry WS (Moles only).  

Science 8:  We reviewed chemistry ideas first (definition of chemistry, units for volume, changes of state, density of an apple).  Then we learned how heat moves in 3 different ways:  Conduction, convection, and radiation.  In the Heat Lab, we tested out the conductivity of 5 types of metals in a controlled experiment, then we drew a bar graph for our data and we designed a "best ever" cooking pot.  In the last few minutes time was given to complete work from Friday:  pg 263 # 1-6, Activity 7-6, WS titled Mini Density Review.  Click here to see the assignment log

Chemistry 11:  After completing balancing mini review #1 we learned how to determine the reaction category by seeing the reactants only.  This allow us to generate reaction products by ourselves.  After doing pg 118 # 67 verbally as a group, we completed the Predicting Products WS, which is due Tuesday.  We also went over conclusions for Lab 6A, to make sure that all of the objectives have been addressed.  This means including values that were mentioned in the objective.  Both the lab and the WS are due Tuesday.  Click here to see the assignment log.

Chemistry 12: We learned how to separate mixtures of ions today, then we read sectoin 3.5 and completed Unit 3 # 29-33 (these are due Tuesday).   The WS titled "Solubility Review" was also given out today.  Click here to see the assignment log.

 

Science 8:  Today I collected pg 251 and 253 from Tuesday.  We reviewed Density a little, then did Lab 7-4 (all procedure steps as well as "What did you Learn" questions # 1-4).  In the final minutes we started the Density Mini Review.  Lab 7-4 and the Density Mini Review will be due Monday. Click here to see the assignment log

Chemistry 12:  We did Lab 19C today - the lab will be due Monday.  I did not collect Unit 3 # 42 - 51, which was due today.  Click here to see the assignment log.

 Chemistry 11:  I collected the WS titled "Writing Reaction Equations".  We reviewed balancing, then completed a Balancing WS to practice our skills.  This animation shows that chemical reactions are simply the rearrangement of atom to form new products, and that no atoms are lost or gained - this is the reasoning behind balancing chemical reactions.  We took notes on the Categories of reactions.  There was a short discussion about adding CO2 to the air by burning fuels - we looked at this graphic to understand global warming.  In the second half we did Lab 6A (Day 1 of 2), then we completed any 12 from Unit 6 # 66.  Only the Balancing WS and U6 # 66 is due Friday.
