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.
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
Others are RADIO & TV,
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
The order is important and to
remember it use the following rhyme!
Randy Radio & TV
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.
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.
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.
is the distance a vehicle will travel in the time it takes you to react to the situation.
Time- 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
when your speed isn’t changing, it remains constant.
A quantity that is fully described by a value, unit and direction
displacement 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!
