Today we spent some time working on our Energy Unit review.  This is due on Thursday.   Your energy test is on Friday and although it isn't open book, you can write down any extra information on your data booklet.  Next we discussed the greenhouse effect and climate change by going through this power point and watching the following videos:   You are responsible for understanding the greenhouse effect and knowing what greenhouse gases are (the first two slides from the power point) for the test on Friday.

Today we worked on the Energy Unit Review and then did a lab:  Thermal Energy of a Nut.  Some selected answers to the unit review are found HERE.

Today we looked at the last topic in the Energy Unit:  Thermal Energy.  We took notes, did some example problems and did some practice problems.  Answers are found HERE. 

We watched these two crash course in physics videos to practice the difference between temperature and heat energy, but don't worry about all the crazy formulas in here!

 Today we practiced KE and PE calculations with this worksheet.   

The answers to Gravitational Potential Energy Calculations (You only need to do #1, 31b, 6 and 7):  

#1) PE = 22 050 J    #2a) 235.2 Kg      #2b) 39.2 J       #2c)68.6 J           #2d) 0J       #3a)1499.4 J (if you consider the first floor to be 2.5 m up)

#3b)8996.4 J        #3c)14994 J            #3d) 16 493.4 J          #4) 980000000 J lost     

#6) 0.204 Kg        #7) 774.8 m           #8) 1.6 m/s2              

Kinetic Energy Calculations:   #1) KE = 945 J           #2) 2070.7 J              #6) 4 m/s         #10) 252.3 m/s

Next block we watched the Bill Nye video to practice energy:

Today we did our open notebook quiz on radioactivity.  Nice work nuclear physicists!   Next we took a few notes on Conservation of Energy.   Homework:  Read and take your own notes on page 203-205.  Make sure you have written down all the types of Potential and Kinetic Energy.

Today we worked on half life and radioactivity.  If you want some EXTRA reading on how carbon dating works, check out the link below.

First we did a lab to determine the half-life of cornium atoms.   Make sure you have completed this lab with a graph, data table, analysis and follow-up questions and turned it in.

Next we did a practice quiz on radioactivity.   The key is found HERE.  We will have an open notebook quiz on radioactivity on Monday.
