Keith Johnson has written an amazing book which is being updated regularly. You can access free powerpoints here. I really hope that he doesn’t mind me reproducing one of them here, but pop along there for a whole list of useful powerpoints for all your classes, or for students to brush up on lots of Scientific skills.
Some people are unfortunate and have colour deficiency. This is usually a genetic condition.
The different types are protanomaly, which is a reduced sensitivity to red light, deuteranomaly which is a reduced sensitivity to green light (the most common form of colour blindness) and tritanomaly which is a reduced sensitivity to blue light (extremely rare).
One of the uses of UV radiation is a security feature of bank notes. Shining UV radiation on to the bank note causes them to fluoresce (the atoms in the material take in the UV radiation and re-emits it as light which we can see)
Look at how advanced the fluorescing shapes and colours are.
IR cameras are used by the police to track for criminals at night but they are also really useful to the fire brigade at finding people in smoked filled buildings, you can’t hide behind a bin bag and even a hand print can leave a “heat print”.
Did you know you can be on the radio? Not very musical but it can drown out Radio Scotland.
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
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
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.
Up until now when you’ve done a poster teachers have probably encouraged you to write very little, draw something eye-catching and maybe have a slogan. There is another kid of poster which is a scientific poster and that is very different.
In a scientific poster you need to get people to understand your
This means that your poster will have writing and often quite a lot, but if you can put the information is a graph or photo- as they say a picture tells a thousand words.
Here are some scientific posters from the kind Science Community at Scottish Universities and also some Science on Stage Posters made by teachers about their work in schools, you might recognise some of them.
Don’t worry if you don’t understand all the content, you are using them as an idea of layout and what you need to add in.
Template for your Scientific Poster
Please use the correct template for your class. You can change any part of the slide, except the header.
Lockerbie Academy’s S2 Forces Unit Material, containing the Assessed Practical and details for plotting graphs in Excel.
Wow! This is an important Physics topic, your first topic in the S2 physics course. All the info you cover in class is given below. We will start at the beginning but can rush through the bits that you’ve covered in primary.
Forces powerpoint and powerpoint pdf file for 2021 onwards
Here is a great song for you to learn the difference between Mass and Weight.
S2 Physics Homework Tasks
Complete a title page called FORCES
In the back of your jotter write a piece “What I learned about myself in S1 Science” This is not the topics that you covered- I know those, but what did you learn about yourself, your ability to think for yourself, try tasks etc. What skills have you learned .
Hookes Law table & Hookes Law graph (this is an assessment piece)
Answering the mass and weight questions
1st June 2019
Revise the work you’ve completed this week and previous weeks
If you haven’t got results for the Hooke’s Law Assessment use the ones below. Copy the results into Excel, find the average extension using the formula =average(range) . Then plot a graph of Weight against average extension.
There is a separate post on EXCEL with details of how to create a table of results and plot a graph in Excel, which is useful for all students studying Physics, and other Sciences too- a useful life skill.
