This week’s episode of Band Goes the Theory was about the Fukushima disaster in Japan.  Part of the programme was filmed at Dounreay, where Dallas investigated the methods being used to decontaminate the site.  You can watch the part about Dounreay by playing this clip.

The whole programme is available for download using the link below (large download).

We started to look at vectors this week. Here is a video I made to help you with the processes involved in drawing a scale diagram.

I found a brilliant timelapse video on the Popular Science site.  It shows the Very Large Telescope (VLT) at work in Chile.

Here are some VLT links to explore

• wikipedia entry
• the VLT website
• series of images from the BBC
• the VLT’s laser guide
• ESO’s top 10 discoveries

You can get a pdf summary of the VLT from the European Southern Observatory (ESO), the organisation that runs the VLT, by clicking on the download link below.

I’m sure you’ll do your best tomorrow.  Remember to check the exam advice for Higher and Standard Grade on BBC Bitesize.

Higher classes – remember my advice to attempt Section B first. 70 of the 90 marks are there and each mark requires less effort than Section A.  Aim to leave 35 minutes for the multiple choice questions.

I’ve put together a table with links to as many past papers and solutions as I can find. You will find the table on the Int2 Physics revision page.  I’ll try to fill in the blank bits when I have some time.

Here is a short video covering the points we discussed when we drew scale diagrams to find displacement vectors.

Most classes have done some work recently on improving answers to the kind of questions that ask you to describe/explain/justify.  I haven’t saved all of the mindmaps that have been produced but this one is fairly typical of the responses generated by a class.  There is a pdf version available to download.

We have almost completed the health physics unit and have spent some time in class practising half-life problems.  You might find the attached instructions helpful as you prepare for the unit test.
