Book/Movie Title: Overheated British Schoolboys Rebel against shorts ban by wearing skirts

Overheated Schoolboys Rebel against shorts ban by wearing skirts is a news article by Stuff.co.nz. The News article is about a group of British schoolboys rebelling against a no shorts policy at their school by wearing the skirts.


I find it encourageing that a group of normal teenage boys from England decided to stand up for what is right and protest for every other student that goes to their school (Isca Academy). The group of boys said they decided to protest for the change because even on days when it is 30 degrees they are forced to wear pants so they decided if they can't wear shorts they would protest and wear skirts. I think what makes it even more amazing is to get the change at their school they wore the skirts to school even knowing they would get in trouble but they didn't care they wanted the change for themselves and their school mates.


What these normal teenage boys done in England by protesting for change has an impact on a lot of people all over the globe. The reason a few teenagers protesting what they believe in at school affects all people is because all around the world especially people in countries in the middle east. People are protesting for all different reasons but even though their reasons for protest are different one thing that everyone has in common with the boys is everyone that protest or argues against something is arguing against injustice and mistreatment and trying to change the world so they are treated properly and this is exactly what these English school boys were doing arguing for change in their community.

Identify acute and chronic responses to exercise

Image result for conor mcgregor

Conclude findings by explaining what is happening to your body as a response to exercise.

As a response to exercise  more blood flows through your capilaries to give your body oxygen and the capilaries in your face close to the surface of your skin will cause your face to go red.The capilierises also help us to get heat out of our body.

P.E Revision Biomechanical Principals-Levers


In the throwing activities, the distance achieved is directly related to the speed of the release. Generally, the longer a lever is, the faster the distal end of the object will move. For this reason, the farther a discus or hammer thrower can position the implement from the body (the axis of rotation) during the turns before the release, the greater the speed of release.

In Shot Put the bicep is the antagonist and the input of force the fulcrum is the elbow joint the load is at the end of the arm.The more extended the the atheltes arm and the higher the position of the athlete the more force and speed the shot put will gain.

Observing the Effect of a Catalyst on a Chemical Reaction

AIM: To observe the effects of a copper catalyst on the reaction between zinc and sulfuric acid.

Equipment: Three test tubes test tube rack 10ml  measuring cylinder dropping pipette granuated zinc copper turnings or powder dilute sulfuric acid h2so4

Method:
1 Add roughly the same mass of zinc to test tube 1 and 3
2 Add roughly the same mass of copper to test tubes 2 and 3
3 Add 5ml of dilute sulfuric acid to test tube . Note the rate of production of gas bubbles.
4 Add 5ml of the acid to test tube 2. Note the rate of production of gas bubbles.
5 Add 5ml of the acid to test tube 3. Note the rate of production of gas bubbles.

test tube 1 Fizz
test tube 2 Bubble
test tube 3 Nothing much happened

PE Revision Test

1.Force summation is...Using as many body parts as possible and moving small mucles last to get maximum power.Or large mucles for power small mucles for accuracy and direction.


2.Projectile motion has 3 factors impacting the projectiles distance what are they
Speed of realese  Angle of realese  Height of realese


3.Balance and stability are impacted by
   BOS Base of support Width and points of contact
   COG Centre of gravity High vs low and shifting                                        What do they stand for
   VLG Verticle line of gravity Always runs through the centre of gravity

 
4.Newtons laws-there are 3 what are they give sporting examples for each Inertia-If you kick a ball it will keep rolling till an outside force stops it. F=ma. Action/Reaction-If you bounce a ball on the ground it will bounce back up.

Observing the Effects of Surface Area on Reaction Rate

Aim: To make simple observations during a reaction between calcium carbonate CaCo3 chips and powder with hydrochloric  acid HCI

Equipment:Boiling tube calcium carbonate chips and powder with hydrachloric acid measuring cylinder spatula

Method:
1:Measure 2ml of hydrochloric acid and pour this into your boiling tube.

2: Holding your boiling tube over a sink of heatproof mat add a pea-sized amount of calcium carbonate powder to your boiling tube.Record your observations below.

3:Repeat the experiment but this time use a chip of calcium carbonate that is roughly the same size as the spatula of powder you used previously.Record your observations below.
 
RESULTS

When using powder it fizzed up.
When using the rocks it bubbled.

CONCLUSION
In conclusion the more reactants there is the faster the reaction will happen or the more surface the faster the reaction occured

Investigating the Effect of Concentration on Reaction Rate

Introduction:In this experiment the effect of concentration on the rate of reaction between sodium thiosulfate and hydrochloric acid is investigated

Equipment: A conical flask measuring cylinder stopwatch black cross on the paper 0.2 mol L-1 sodium thiosulfate 1.0 mol L-1 hydrocholric acid

Method

  1. Put the piece of paper with the X on the bench and put the conical flask on it.
  2. Measure 10mL of Sodium Thiosulfate and put it into the conical flask.
  3. Measure 40mL of Water and put it into the conical flask. Swirl to mix.
  4. Measure 5mL of HCl.
  5. Pour the Sodium Thiosulfate into the conical flask, start the timer and swirl the flask.
  6. Stop timing when the you can't see the cross on the paper.
  7. Wash out the flask thoroughly.
  8. Repeat experiment 20mL of Sodium Thiosulfate and 30mL of Water.
  9. Repeat experiment 30mL of Sodium Thiosulfate and 20mL of Water.
  10. Repeat experiment 40mL of Sodium Thiosulfate and 10mL of Water.
  11. Repeat experiment 50mL of Sodium Thiosulfate and no Water  




RESULTS

10ml of sodium thiosulfate/40ml of water 4min 43 seconds
20ml of sodium thiosulfate/30ml of water 2 minutes
30ml of sodium thiosulfate/20ml of water 54.63 seconds
40ml sodium thiosulfate/10ml of water 44.22 seconds
50ml of sodium thiosulfate/no water 33.62 seconds

Conclusion
In conclusion the more concentrated the chemicals  the the faster the chemicl reaction takes place
