Science 10

Today we wrote the Energy Unit test.  When finished read page 10-18 in text and take notes.  This needs to be handed in for marks.

Today we played some review games to help us review for the Energy Test.  Here are the answers to the calculation section of the review.  

Next we watched the movie 2040 on sustainability.  If you are working at home, watch some clips of the movie to understand what some solutions for agriculture, transportation, energy could be.

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:
