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.
A titration calculation

A titration calculation

(0)
I have tried to produce a clear example of an acid/base titration for use on the board or as a handout. I used colour to make it as clear as possible.
Chemical Analysis wordsearch

Chemical Analysis wordsearch

(0)
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)
Interactive electronic configuration

Interactive electronic configuration

4 Resources
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.
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.
Rate of reaction with a gas syringe simulation.

Rate of reaction with a gas syringe simulation.

(0)
I have made a simulation of the marble chips and acid experiment at four different concentrations of acid. Just double click on the “gas syringe.html” file and it will open in your web browser. You could use browser zoom controls to make it huge if you wish. Maybe take measurements of volume of gas evolved against time or just use to introduce the experiment or revise. ( the price for this could save your department many times in broken gas syringes.)

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.

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.
Balancing-ionic-half-equations

Balancing-ionic-half-equations

(0)
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.
The Mole

The Mole

(0)
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.
