I taught chemistry for 25 years. I now provide tuition online. I just like nicely produced, imaginative resources.
Chemistry
Types of chemical reaction.
I made a very simple information sheet/poster. PDF so can be printed at any size.
End of term Science crossword
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.
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)
Free radical substitution cut&stick
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.
Animated electrophilic addition of hydrogen bromide to ethene.
I have improved my video of this reaction mechanism.
Recognising the Type of Reaction
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.
Bundle
Interactive electronic configuration
Drag and drop resources to reinforce electronic configuration in atoms and how this underpins the layout of the periodic table.
Please note: in order to provide a rich interactive experience, my drag & drop 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.
The pH scale
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.
Esters worksheet
Introduction on the front, eleven questions on naming esters on the back. All in black and white for photocopying cheaply. To save you some time. Useful for GCSE, but could be used at A level.
Solid, liquid or gas?
Students work out the state different substances are in at room temperature, given their melting point and boiling point.
Chemical Formulae
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.
balancing equations for burning hydrocarbons.
A simple black and white worksheet of two sides, with questions on balancing equations for the combustion of hydrocarbons.
The Mole
A readily photocopied (B&W) worksheet on calculating numbers of moles. The first page is introductory, with some examples, the second page has ten questions of introductory difficulty.
