Worms move in!

Well, Wednesday 4th September one group in the Climate Catastrophe Group built their wormery. We are going to look into recycling of food and break down of fruit and vegetables. Worms do create greenhouse gases, but play an important part in maintaining the soil, which has taken a hammering over the last 60 years.

Unfortunately the worms arrived late on Thursday 5th September and had to be in the wormery before the weekend. The students hadn’t quite finished the wormery, so many came up during their lunch break and helped get the worms a temporary start. Our biggest concern is the amount of moisture that we need. The wormery isn’t a draining one, so getting the air and moisture levels is important. We also had to put all the worms in the one box as the second box wasn’t ready.

Let’s hope the worms make it through the weekend. The suspense is terrible and the temperature this weekend was pretty warm, the first dry weekend in four weeks- drat.

Climate change

In these posts I’ll try to add content about the most important topic facing our world. I will only use evidence based Science to make my points.

Having Mr Physics on the case helps as he’s been involved in measuring this stuff from the late 1980s to the beginning of the twenty first century.

Here is the definitive link for all things Climate Change, ask an adult if it is too hard.

The Electromagnetic Spectrum

The electromagnetic (em) spectrum is a collection of transverse waves that all travel at the same speed in air, the speed of light, 300 000 000 m/s. (equivalent to 7.5 times round the Earth every second)

One of the waves is VISIBLE LIGHT

A=amplitude λ = wavelength

Others are RADIO & TV, MICROWAVE.

The others are INFRA-RED, ULTRA VIOLET, X-RAYS, GAMMA WAVES.

The only difference between each of these waves is their wavelength or frequency. They all fit the formula

Speed= frequency × wavelength

v=f λ

The order is important and to remember it use the following rhyme!

Randy                  Radio & TV

Monkeys              Microwaves

Invade                 Infrared

Venezuela           Visible

Using                   Ultraviolet

Xylophone           X-rays

Gunships             Gamma

Period, T, is the time for one wave to pass a point and is measured in seconds.

Frequency, f is the number of waves being produced or passing a point per second. Frequency is measured in Hertz (Hz)

Here are lots of resources for you to check and practice. My utmost apologies if I have not credited people for sending this material. As soon as I know who you are I will thank you personally.

S3 Physics Review

Homework Exercise

S3 Review (Complete at the end of the course)

We have covered three topics this year.

  • BEYOND THE VISIBLE (covering the EM Spectrum v=fλ, uses of EM radiation, research projects, make your own practical, reflection, refraction, diffraction)
  • ROAD SAFETY 2, (covering acceleration, forces, vectors, Road Crash Investigators, Tart Ma Kart, Newton’s Three Laws of Motion)
  • SPACE. (definitions of space, the big bang, The Martian, Rockets, Newton’s Three Laws of Motion review, stars, light years, challenges of space travel, Moon Myths)

Mark each topic out of 10, with 1 being the worst and 10 being the best- GIVE A PROPER REASON for your score a short paragraph at least saying
which parts of each course were the best and what were the worst . State what SKILLS you’ve learned such as calculator work, arithmetic, road safety skills, Road Crash Investigator, Experimental Design (Beyond the Visible) Space.

Lastly state what you wished we had changed. Only sensible answers.

S3 Space

We aim to check out lots of information about Space and the Universe. As it is rather a large topic and contains all we know and lots that we don’t we wont be able to cover it all. This is the content statements that we hope to cover.

S3 SPACE OUTCOMESDownload

As part of your course we expect you to research one unmanned SPACE mission. You can choose any space agency, NASA, ESA, Roscosmos, etc

You need to consider

  • When was the mission?
  • What was the purpose of the mission?
  • How long did the mission last?
  • What did the mission conclude?
  • Did the mission exceed expectations?
  • What information can you share about the mission?
Some of the Space Agencies from across the world. Some are state sponsored, some private companies.

TermMeaning
At rest not moving, the object is stationary. It is not the same word as pens and pencils which are stationery!
Average Speedthe distance of the whole journey divided by the time for the whole journey.
Braking Distancedistance the vehicle will travel as the brakes are applied.
Displacementhow far you have travelled in a straight line. We would say “as the crow flies” You must quote a direction when writing down a displacement.
Distanceis how far you have travelled. It is another name for length.
Dynamicsthe part of mechanics dealing with Forces.
Instantaneous Speedthe speed at which you are travelling over a very short distance.
KinematicsKinematics means the part of mechanics dealing with motion, speed, acceleration etc
MechanicsMechanics is the branch of Physics dealing with motion (how things move)
Reaction Time the time it takes a person to react to a situation and understand the dangers.
ScalarA quantity that is fully described by a value and unit
Speed is the distance travelled in unit time.
Stopping Distancestopping distance= thinking distance + braking distance .
Thinking distanceis the distance a vehicle will travel in the time it takes you to react to the situation.
TimeTime- is how long your journey took. It is measured in seconds or during our road safety topic hours. We never write sec or secs in Physics to mean seconds
Uniform Speedwhen your speed isn’t changing, it remains constant.
VectorA quantity that is fully described by a value, unit and direction
Velocitydisplacement covered during the journey divided by the time taken. You must quote a direction when writing down a velocity

Are you really stuck on drawing that graph in your homework? Here is a hint!
