“The experiments detailed in the course specification can be used for assignments. Centres are obviously free to choose other experiments if they wish, as long as they’re commensurate with the level. One of the advantages of using the experiments in the course is that you can be sure that the physics is accessible and at the correct level.

In the past, we saw some examples where centres had used rotational motion experiments with N5 candidates, and you could tell that the candidates had no clue what they were doing. It’s also been obvious at National 5 level that some centres are still using kits they had for Standard Grade investigations, which is fine, but you do need to make sure that the underlying physics is accessible. To give an example, solar cells was always a popular topic for Standard Grade and we see centres using them for National 5, but explaining how a solar cell produces a potential difference is something N5 candidates will probably struggle with (Higher candidates do when we ask them in the exam).

Higher, of course has the alternative two experiment route, which is quite popular especially with topics such as internal resistance where they can do the two experimental variations.

Your colleagues may wish to have a look at the Physics pages on the Understanding Standards website:

SQA – Understanding Standards: Introduction (Nat 5)

SQA – Understanding Standards: Introduction (Higher)

where they will see several exemplars based on the experiments detailed in the course specification.

If you have things that have worked well in the past, then it’s worth remembering that nothing has changed in any of the coursework requirements, and therefore they should still work in the same way.”

This summary is based on the updated information from the SQA. The first two links are for the candidate guide which is produced by the SQA and contains the information that students can access. This can be taken into the reporting stage of your assignment. It is important to check off what you have done at the end of your assignment with the marking instructions. Prior to this it would be a good idea to have gone through the Practical Skills Booklet.

The link below takes you to the full information document which is produced by the SQA. It is a current document. This cannot be taken into the Reporting stage of your assignment, although the document above can.

Completing Practical Work

Before you complete your assignment you’ll need to be familiar with how to complete a practical and write up. CLICK ON THE DOWNLOAD button to download a Guide to the Practical Skills Booklet. Hopefully it will be useful to everyone doing HIGHER ASSIGNMENTS.

Many think this has too much on Excel but it can be removed from the word document if you are going to hand plot your graph.

I’d be grateful for feedback on this document and how it can be improved. Thanks.

My thanks to my colleagues at Dumfries High School, Mr Belford and Mr Viola for allowing me to add this flipchart which I have converted into a pdf file (hence the apparent pages of not many changes- it works well on a flipchart) for you to see how to go about an assignment.

The Expanding Universe Practical

A great little practical with washers, that was used as an exam question!

Try the following practical

Expanding Universe Experiment

To understand how the redshift of galaxies is due to the expansion of the Universe, try the following experiment.

You will need the following items:

  1. A round balloon (do not use a long, thin one).
  2. Some coloured stick-on dots (at least 5 different colours).
  3. A piece of string about 50cm long.
  4. A ruler.
  5. A stopwatch or other timer.

Step 1 : Setting Up

You will need to work in teams of at least two, one to blow up and hold the balloon and the other to make the measurements.

Before you start, draw a table for your results like the one below with the colours of your five dots in the 1st column:

Colour of DotFirst Distance D1 in cmSecond Distance D2 in cmChange in Distance        D2 – D1 in cmSpeed v in cm/second
Red    
Green    
Blue    
White    
Yellow    
Time to fully inflate the balloon:        seconds.

Step 2 : Making the Measurements

Putting dots on the small balloon

Blow up the balloon a little bit and hold the “nozzle” closed, but do not tie it up.

Stick your five dots onto the balloon. Try to spread them out over the whole balloon.

stick dots

Each of the dots represents a whole galaxy, with the surface of the balloon being the Universe that they exist in.

Choose one of the dots to be your “home”. You can choose any of them.

Step 3

Use string to measure the distance between two dots

measure dots

While one of you holds the balloon, the other one can use the string to measure the distance from your “home” dot to one of the other dots.

Now measure the string distance with a ruler.

When you have measured the distance, write it down in your table in the D1 column.

Step 4

Measure the distances from the “home” dot to all the other dots as well and fill in that column of the table.

Note: The distance from your “home” dot to itself is zero.

Step 5

Now carefully blow the balloon right up, using the stopwatch to time how long it takes. Write down the time in seconds.

Step 6

Now re-measure all the distances from “home” to all the other dots and write then down in the D2 column of your table. Don’t forget that the distance from your “home” dot to itself is zero.

You now need to work out the speed of each galaxy. Remember that:

Here, the Distance travelled is the difference between D1 and D2, so calculate D2 – D1 for each of our dots and write them in the 4th column on the table.

Step 7

The Time taken is the time to blow the balloon up. Work out the speed V for each dot and put it into the 5th column. Because your “home” dot has not moved, its speed will be zero.

Step 8

We are studying how the speed that galaxies seem to have gets larger for galaxies that are further away.

The best way to see this is to plot a graph showing the distance along the bottom axis and with the speed up the side.

This means that you need to plot a graph with axes like the one below:

speed v distance

Put the points for all your dots on the graph using D2 as the Distance.

Step 9 : What does it all mean ?

Use the ruler to draw a straight line that goes as close to as many of the points as possible (don’t forget the “home” dot!)

Think about the following questions and discuss them:

  • Are the speeds of all the dots the same?
  • If not, do they get faster or slower as they get further from the “home”?
  • What would be different if you had chosen a different “home”?
  • What would have been the same?
  • What do you think this tells you about the way that the Universe expands and the redshift of galaxies?

If you are not sure about some of the questions, can you think of a way changing the experiment to make them easier to answer?
