End of term Science crossword

(0)
A little bit of ‘learning without working’ activity for the end of term, in black and white for easy cheap photocopying. Suitable for all abilities, but earlier years may need to look some clues up. The answers are included.
Solid, liquid or gas?

Students work out the state different substances are in at room temperature, given their melting point and boiling point.
Chemical Analysis wordsearch

Chemical Analysis wordsearch

A simple wordsearch on 1 side of A4. It is quite a challenge! For GCSE chemists. ( I have now removed an error which had two letters in one box and one box with a space. I had to make it bigger and spread the puzzle onto two sides, one side with clues and one with the puzzle grid. Apologies to those who bought the defective version- contact me for a replacement)

A simple worksheet on IUPAC nomenclature. A set of simple rules, followed by nine questions (branched chain alkanes and alkenes) over two sides. With separate answers sheet. First of a series.
Chemical Formulae

Chemical Formulae

(0)
A simple, photocopiable worksheet (black and white!) that gives practice at interpreting simple chemical formulae. The examples get harder as you proceed. It is comprised of two pages of examples. It is suitable for KS3 and KS4 students. It could be used in class or for homework.

NMR examples explained

14 Resources
Colourful, comprehensible, clear examples to illustrate the interpretation of proton NMR spectra. Could be used as a display, or on the whiteboard, or as a handout.

This is a very simple worksheet. Link the name of the polymer to its monomer. Then draw the repeating unit. A drag and drop version may follow. Watch this space.

Free radical substitution cut&stick

(0)
An introductory sheet of answers, followed by cut and stick exercise for this challenging mechanism. Cut and stick promotes familiarity with the mechanism, promotes discussion when done in groups, and is enjoyed immensely by sixth formers.
Recognising the Type of Reaction

Recognising the Type of Reaction

(0)
One of the most useful skills in answering many GCSE chemistry questions is to work out what type of reaction is involved in the question. This helps you work out what the products may be, but also answer other questions about the reaction. Students often find this very difficult, mainly due to a lack of practice and experience. This simple information sheet with questions at the back is in black and white so can be readily photocopied.
Phenol worksheet

A simple, readily photocopied worksheet on phenol. Information on the front, six questions on the back.
The pH scale

The pH scale

(0)
I made a very simple ‘fill in the gaps’ worksheet. It may be useful because it focuses on the adjectival and noun words in this topic.
Effect of pH on amino acids

Effect of pH on amino acids

(1)
I made a crazy interactive widget to illustrate the ionic forms of glycine. Just for fun really. Please note: in order to provide a rich interactive experience, my interactive resources are mini-web sites local to your computer. After unzipping, they comprise a folder containing the main .html file and another folder containing the graphic resources and my coding to make the resource work. Double click on the .html file and the resource will work. If, however , you move or delete any of the files from this hierarchy, the resource will not work.

Quick and short presentation on how to balance the manganate (vii) half equation, to save you time. I have now added the oxidation of ethanol by acidified potassium dichromate (VI) as another example.
