Science 10 Final Exam June 24th 12:45 pm

• Make sure you are on time and you have a pencil and a calculator!

Science 10 Review package in Mr.Head Pick-Up folder on P: drive

• Email me if you have not received a copy and I will send you one

Things to consider...

Your Science 10 grade is

• 35 % Coursework (assignments )
• 35 % Unit Exams
• 30 % Final exam

So, your grade as of right now is that percentage out of 70 %. To see how much of your final grade is confirmed, multiply your grade (as a decimal) by 70. This value can be called X.

The final exam is the remaining 30 % of your grade. So if you want to know what your mark will be based on a hypothetical Final Exam Test score, multiply that % by 30 and call it  "Y". You then add X and Y to see your final grade.

Example:

Let's say you currently have 72% ...

0.72 x 70% = 50.4% of your mark is confirmed.

REMEMBER - a Final grade of 60% is required to move on to 20 level sciences

If you then score 85 % on the final exam...

0.85 x 30% = 25.5%

50.4% + 25.5% = 75.9% or 76 %Final Grade

Talk to me on Monday if you have any further questions about this.

Prepare questions for Monday about specific areas in Chemistry, Physics, Biology and Climate that are still unclear to you.

I will be at school all week if you require further help before June 24th.

Science 10

The science of work and energy. W = Fd = Energy. If you are applying a force to an object over a distance you are doing work on that object. You are also transferring energy to that object.

Force (N) is equivalent to mass (Kg) times acceleration (m/s² ) . F = ma. Our units show that  1 Newton (N) is equivalent to 1 Kg m/s² 

Work is measured in N-m (Newton-Meter) or more specifically a Joule (J). Energy is also measured in Joules.

Gravitational Potential Energy  ( E_{p (grav)}  )  is the stored energy an object has by virtue of its position of above Earth's surface. Gravitational Potential Energy is a function of mass (m) times the accelerations due to gravity (g= 9.81 m/s² ) and height (h)

E_{p (grav)}  = mgh . Our units would be ...    J = Kg x m/s²  x m =  (N) m

Also,  Weight = mass (m) times the acceleration due to gravity(g) . (1 Kg m/s² ) = 1 Newton. Therefore, weight is a force.

This video talks a little bit more about Kinetic Energy (  E_k = 1/2mv² ) which we will talk about next week. He goes farther into the concept than I would expect from you at this stage. You should still check it out!

Sam	22	26	16	4	0	0	68
Carson	31	24	16	8	0	0	79
Mr. Head	33	30	16	8	0	0	87

We're now into the Final Four. If there is a "0" in the remaining two round boxes that means you cannot receive any more points in this tournament for that round.  Francis has taken the lead and control of this competition behind the "pick of the tournament" in Syracuse taking them all the way to the championship game. If Syracuse beats UNC that will give Francis another 16 points and eliminate Ben and Brayden who have UNC winning the tourney (which would give them each 24 more points and Brayden the crown).   Sam, Riley and Jack can add to their point totals with wins by Oklahoma (Sam), UNC (Riley) and Villanova (Jack) in the fifth round, but they cannot win this competition because they don't have those teams going any further.  Merrick has a solid chance of catching Francis. Merrick has Villanova winning the whole thing. If Villanova wins and does not play Syracuse in the final, he is your winner!

To sum up.

If #10 SYRACUSE WINS IT ALL...FRANCIS WINS!

If  #2 OKLAHOMA WINS IT ALL... FRANCIS WINS!

If  #1 NORTH CAROLINA WINS IT ALL...BRAYDEN WINS!

If # 2 VILLANOVA WINS IT ALL...MERRICK WINS!

However, if VILLANOVA beats SYRACUSE in the Final... Francis and Merrick tie, and nobody wants that...well maybe Francis and Merrick do.

Good luck Gentleman!
