KS4 Chemistry calculations question bundle

(0)
This is a** complete set of calculations notes, questions and worked answers** for IGCSE / GCSE chemistry, or for students crossing into year 1 of A level chemistry. It is suitable for any of the exam boards. Material covered: Calculating relative formula mass and number of moles Calculating empirical formulae Calculating masses (reactions involving solids only) Calculating with gases (reactions involving only gases, or gases and solids) Calculating with masses, gases and concentrations Calculating waters of crystalisation Bond enthalpy calculations Calculating enthalpy change from experiments, Q = mcΔT Calculating which material is in excess Each sheet contains a full, logical worked method plus notes of common errors to be avoided, then questions in exam style but not taken from papers - leaving the exam papers for the student to attempt unseen another day. Answers are either on the sheet, or on a separate sheet also provided. If you do not want to purchase this as a bundle, the resources will also be posted separately.

AS and A2 Chemistry practical resources

(0)
A full set of detailed notes comprising the most common practical experiments covered at AS and A level chemistry, based around OCR A and Edexcel International boards, but applicable across most exam boards. Each document contains a description and notes on the experiment, followed by exam style questions on each experiment. Where needed, a set of representative results has been given for the student to work from. These are ideal for any student who cannot do the practical element of the A level and should give you the practice in answering questions based on the core practicals. AS: Investigating the rates of hydrolysis of some haloalkanes Analysis of some inorganic and organic unknowns (chemical tests) Chlorination of 2-methyl propan-2-ol with concentrated HCl Determination of the enthalpy change of a reaction using Hess’ Law Finding the concentration of a solution of hydrochloric acid Measurement of the molar volume of a gas Oxidation of propan-1-ol to produce propanal and propanoic acid A2: Preparation of a transition metal complex Using titration to follow the rate of iodine propanone reaction Finding the Ka value for a weak acid Investigating electrochemical cells Preparation of aspirin Finding the activation energy of a reaction Redox titrations with iron and potassium manganate

The effects of DDT pesticide on bird populations

(3)
KS3 year 9 worksheet on the effects of DDT. Short passage to read, questions to answer and a bar chart to draw showing how the DDT builds up across the trophic levels. Some will find the bar chart difficult, but it works OK if you stress its the shape you are after, not necessarily accurate plotting.

Investigation into the morphic forms of chocolate

(2)
This powerpoint has been created using information from the PracticalChemistry website (which is excellent). You need to preprepare some chocolate by melting it and recooling it in the kitchen. The melting point, taste and texture of this chocolate are then compared to a fresh batch of the same. I used buttons as it was the simplest to regulate the amount used by the class. Water for melting the chocolate needs to be at no more than 42 deg C or it melts too fast to see the changes. Great fun, really enjoyed the experiment and although we could not necessarily determine melting point accurately enough to determine the morphic phase, we could at least see more than one morphic phase in the chocolate.

Assemble your own lunar Lander

3 files for print out to build your own lunar lander (LEM) as used in the first lunar landings. Best printed onto thin card. Assembly requires some fine motor skills, but KS3 main stream should manage it on their own. My Mum’s Brownies (KS2) managed it in pairs, sometimes with a little help. Copyright is to my Dad who designed it, but is happy to allow all users of TES and their classes to use this resource.
