Year 6 back in the lab after exams

Year 6 had their first lesson after the exams in the science labs.

Time to get down to some practical work and so a little investigation into physical changes in glass rod is just the thing.

Nothing too cerebrally taxing on a Friday afternoon straight after exams

But a very useful set of skills being learnt

And some assessment of risk, dealing with melting glass.

And lots of fun too

It can also bring out the artist in you

Revision

The exams are fast approaching and while the best revision is done in class we can't always give as much time to it as we might ideally like as we still have plenty of syllabus to cover.
If you need any extra guidance then the page called Science at Brambletye might help.

7N have a concentration problem

Two samples of hydrochloric acid.

Which is more concentrated?

How to find out?

Measure out a certain amount of acid

Add universal indicator to see the pH. 

Add alkali from the burette until the solution becomes neutral. 

Repeat to see if the result is reliable then do the same for the other acid.
