## viewing the solar eclipse

We spoke about the eclipse in class today.  It’s really important that you follow advice for watching the eclipse safely to avoid permanent damage to your eyes.

You can buy eclipse viewing glasses online.  They look like this

and only cost a few pounds per pair.  Make sure any glasses you buy have the CE mark on them.

Here is one UK retailer of eclipse viewing glasses who still has them in stock.

Although we’re not in the totality (100%) zone, Thurso is well placed to get a good view.  Here is a simulation for Orkney, our view will be very similar.  Click on the picture to start to animation.

## AH uncertainties – post 3

Here is Stephanie Bell‘s booklet – A Beginner’s Guide to Uncertainty of Measurement.  There’s a lot of useful information in here, so please do have a read during the holidays.  If you see any issues in here that might affect what you are doing with your procedures or data handling, please let me know.

## AH uncertainties – post 2

Here is the second uncertainty guide.  It is a more recent document and covers Higher in addition to Advanced Higher.  You’ll probably find page 11 onwards has the most relevant information for investigation work.

## AH uncertainties – post 1

Here is the first of the uncertainty documents to help you with your investigations.

The final page will help you to quantify some of the calbration uncertainties in instruments.  If you use these values, remember to reference Learning & Teaching Scotland as the original source of the booklet.

We’re going to the library for the next few periods. Download the instructions using the link below. Use your own LO3 data instead of the numbers I have provided.

By the end of this activity you will be able to;

• manipulate raw data using formulae in cells
• plot a graph of your results
• add a line of best fit
