Some of you asked for revision questions ahead of the unit assessment. Down load these problems from older past papers. I will add a secoond post with the answers shortly.
dynamics and space
temperature, colour and line spectra
We’ve been looking at how the temperature of an object can affect it’s appearance. The attached handout recaps on our work in class and provides some examples of line spectra.
changing state – latent heat of fusion/vaporisation
Before the holidays, we performed a set of experiments to determine the latent heat of fusion and latent heat of vaporisation of water. Next week, we’ll review that work and think about possible reasons why our results were not closer to the “book” values.
The attached pdf provides a summary of the topic.
National 5 – Satellites
We’ve started looking at telescopes and this BBC programme from 2 years ago featured the replacement for Hubble, the James Webb Space Telescope. The presenter, Maggie Aderin Pocock now hosts The Sky at Night on BBC4.
Please take some time to watch both parts of the film. Maggie covers the basic idea of satellites, how we achieve geostationary orbit, looks at examples of Earth observation and the manufacture of the James Webb’s massive 6.5m mirror. In part 1, around 17 minutes in, you’ll see satellite footage over the Highlands, can’t quite see Thurso though.

If you want to download a copy of the video to watch later, use the download link below. Please be patient, the file is about 660MB in size.
extra nat5 revision materials
You can also use these notes to prepare for the test on Monday. The test will cover everything up to page 46 in the attached file, but you can skip pages 39 & 40 on Newton’s third law.
Thanks to Mr Noble for sharing his notes.
Nat5 revision materials D&S unit
Use these materials to help you prepare for the assessment at the start of next week. Studying up to page 7 of the attached file will cover the topics in the test.
National 5 – Work
Here is a short summary of the Work topic from the Dynamics and Space unit.
National 5 – Forces
We’ve been learning about forces over the past two weeks. Here are some summary notes to help you with the key points of this topic.
national 5 assignment – part 2
The second programme is all about the current state of car safety.
We follow a car safety team at Volvo as they prepare to crash two cars together to collect forces data, learn how emergency medicine procedures are changing to improve outcomes for car accident casualties, and learn how sensors are used to monitor the human body’s response to a collision.
Please watch both programmes before Thursday 18th February.
As with the first video, please check you are connected to wifi before downloading as the video file is quite big.
national 5 assignment – part 1
We’re going to start work on the assignment task next week. You’ll spend 2-3 periods researching car safety online and choosing a particular topic to explore in more depth. Before we go into the ICT room, I’d like you to watch two videos about car safety.
The first programme looks back at the history of car accidents and the work that has been done to reduce deaths on the road. While many of the clips shown are quite old, they show just how far we have come in our understanding of the science behind making cars more safe.

Check you’re using wifi before downloading – it’s a big file!
