 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:

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.

 Today we took some notes on radioactivity and half lives.  See Tyler's videos for help with this concept

Next we did some practice problems found HERE.   Check your answers HERE and HERE.   Finally we watched a video on the most radioactive places on EARTH:

Today we took some notes on radioactivity using this power point.  Next we practiced some equations using this worksheet.  Check your answers here.  Here is a tutorial on writing nuclear reactions if you need to watch it in action again.  

Science 10

Today we introduced the concept of energy to the class.  First we took some notes on energy using this power point.  Next we did a worksheet "Introduction to Energy" answers are found HERE.   Make sure you also read page 202-204 in the text book

Science 10

 Today we wrote the Chemistry Unit test.   Nice work balancing all those equations and compounds......👏💪. Next read and take notes on pages 222-223 in your text as well as 228-230.  Turn these notes in.  

Have a great weekend!

Today we did the lab 8A (posted in yesterday's blog):  Classifying Solutions of Ionic Compounds.  Make sure you turned this lab in (no conclusion necessary). 

Everyone also turned in the Chemistry Test Review.  ANSWERS ARE FOUND HERE.  

Science 10

Today we went over the answers to the Classifying and Balancing worksheet from yesterday.  Next we practiced some balancing skeleton equations with this worksheet.     

We also practiced some ionic compound naming with this worksheet.    We watched a power point to review some concepts of Acid and Bases.

Finally we set up a lab for tomorrow by filling out this worksheet with the starred parts.  Use page 224-225. 

CHEMISTRY TEST REVIEW IS DUE ON THURSDAY!!!

Science 10

Today we checked the practice problems on page 133.  Next we took notes on Classification of Reactions found HERE.     We worked on our TEST REVIEW which is due on Thursday.   Finally we did  to analyze and observe the 6 different types of chemical reactions.   

We watched a short video on acids and bases.  There is also a video of types of reactions by good old Trevor!!    Your homework is a practice sheet on Types of Reactions....
