## The assessment week for S2 is from 9-13 October. 12% is for Hookes Law Graph, make sure it is printed off and handed in.

Ahoy there! This is Mrs Physics boating in the Scottish waters to bring you information for your BGE Science Courses.

Before we start I’d like to share with you why I believe the most wonderful subject you’ll study at school is …….PHYSICS.

Physics is the scientific study of matter and energy and how they interact with each other. This energy can take the form of motion, light, electricity, radiation, gravity . . . just about anything. Physics deals with matter from sub-atomic particles (i.e. the particles that make up the atom and the particles that make up those particles) to stars and even galaxies. This sounds terribly dull and not relevant to many of you, but let me sum it up this way.

Physics is the subject that delves (explores) into our wonderfully and beautifully made universe and tries to describe things using laws.

Have you ever really thought why a pen falls? Why does it always fall downwards? Because of gravity you say! A physicist says yes, and then asks, but what causes gravity? What is gravity? See if you can come up with an idea about what causes gravity.

Another question! Do you feel like we are moving? No, well why do we have day and night? The Earth must be spinning, or something must be moving around us. Which way are we moving? As the sun rises in the east and sets in the west, we must be turning anticlockwise as we stand. That means we are going pretty quickly.

You probably know that
speed = distance / time,

…where the distance travelled, is the circumference of the Earth and the time is one day (the time for the Earth to spin once on its axis).

speed in miles per hour= Circumference/24 hours
speed = π x d / 24
speed = 3.14 x 7,918 / 24 = approx. 1000 mph

Obviously in Scotland we are travelling slower than that? Why? Amazing!

The first two Physics Courses you will study are the ELECTRICITY topic and the ENERGY and SOUND topic. This is the only time you are allowed to use the word “Electricity,” as a title to your unit. We will learn why during the course of the term.

By the end of the course I hope you’ll understand all these jokes, as well as having a really good idea of the Physics behind “electricity”.

Two atoms were walking down the street towards Home Bargains when one of them said, “I think I lost an electron!” “Really!” the other replied, “Are you sure?” “Yes, I’m absolutely positive.”

A neutron walked into a bar and asked, “How much for a J2O?” The bartender smiled and replied, “For you, no charge.”

Question: What is the name of the first electrical detective?

The second Physics topic in S1 will be a practical based research topic on ENERGY and SOUND.

Here is a joke about sound.

Two sound waves were travelling to their destination when they suddenly crash into each other.

The first wave says “Hey, are you okay?

“The second wave says “Oh I’m fine, it just Hertz!”

Scientists have determined that the most irritating sound to the human ear is the sound of a knife cutting a glass bottle. And the second-worst sound is a fork scratching a glass bottle. Evidently they did all their research at the Picnic for Morons.
– Peter Sagal

I hope you’ll enjoy your course and love it as much as Mrs Physics.

Remember

“If we knew what it was we were doing, it would not be called research, would it?”
― Albert Einstein

“Somewhere, something incredible is waiting to be known.”
― Carl Sagan

“The fact that we live at the bottom of a deep gravity well, on the surface of a gas covered planet going around a nuclear fireball 90 million miles away and think this to be normal is obviously some indication of how skewed our perspective tends to be.”
― Douglas Adams, The Salmon of Doubt: Hitchhiking the Galaxy One Last Time

So you’ve got to the bottom of this post, you must be keen so here is a video that covers in detail what Physics is, the more you know about Physics the more weird the world appears. It takes you from N5 Physics to well beyond AH. Let me know what you think.

PS Don’t forget to post a photo of Mostly Harmless if you see it.

What is the homework we ha e to do

1. bge says:

Hi A, it ought to be written in your planner! Forces booklet 8 pp18-20. For 9am this morning.

1. A. says:

Okay mrs h but I can’t find the table we have to draw on my note sheets

1. bge says:

Then you’ve got the wrong page! Go to course notes on the top menu bar, choose Forces from the drop down menu, then go down and search for the document Forces8.pdf Open this up and it’s above the table of Weight on other planets. Alternatively, as you ought to have done, come and log in break or lunch and not 11:30pm!

Jotter in the tray A.

2. Emma says:

My laptop on Friday didn’t let me open the slideshow so i tried at home and instead of the 80 or so slides that you said that we had to copy the important parts of, there was only 20 slides.

1. bge says:

Sorry to take time to respond Emma, I’ve saved it as 6 slides to a page, so the slides are all there, just six to a page. I’ll sort it out Monday P1
??

3. Emma says:

When is the test?

1. bge says:

Soon, date to be confirmed, but probably next week. I will tell you Friday 20th in class.

4. Emma says:

Thanks for getting the comment box back Mrs H!

I had to have help from Sir Lancelot, but I think I’ve cracked it now. I’ve posted about it on the blog, but I need to re-write it. I wrote it when I was far too tired and there are too many mistakes.
