I am a GCSE and A-level Chemistry specialist teacher in a 14-18 school with 15 years teaching experience and several years research experience. I provide GCSE, AS and A2 Chemistry resources (mainly for the AQA specifications) to help students practice the concepts learned in lessons and I am a firm believer in 'Practice makes perfect'. I strive wherever possible to include the answers to the worksheets.

GCSE Chemistry Elements, Compounds and Atomic Structure Starters, Plenaries and Short Activities

(0)
This resource contains 54 different Chemistry lesson starters, plenaries and short lesson activities for GCSE Chemistry. They would suit all GCSE Chemistry courses which cover elements, mixtures and compounds, atomic structure and sub-atomic particles, isotopes, electronic arrangement, calculating relative atomic masses, ions and charges, and writing and balancing equations. These worksheets were designed for the AQA Chemistry specification for C1 Atomic Structure and the Periodic Table. There are four identical copies of each activity per A4 page to allow students to glue the small worksheet into an A5 exercise book and still have room to complete working out on the same page.

AS and Year 1 Free-radical substitution Mechanisms Revision - Lollipanisms (Lollipop Mechanisms)
hf583hf583

AS and Year 1 Free-radical substitution Mechanisms Revision - Lollipanisms (Lollipop Mechanisms)

(0)
A revision activity for learning and practicing free-radical substitution reactions. The above resources are needed along with a set of lollipop sticks. The stickers document contains 3 halogens (fluorine, chlorine and bromine - labelled as A, B and C) and 10 alkanes/halogenoalkanes (labelled 1 to 10) for the halogen to react with. Each pair or group of students should have a set of lollipop sticks containing 9 sticks with halogens printed or written on them (3 of each halogen) and one each of the 10 alkanes/halogenoalkanes. The sticks could be colour coded by adding a stripe of colour or washi tape around the top edge for ease of seeing. Students pick one halogen and one alkane/halogenoalkane and write the full mechanism including the initiation, propagation and termination steps. The answers are provided on 8 answer sheets which are set up to be printed on sticky labels (4 per sheet) or directly onto card to be cut up into A6 size. The cards could be ring bound (30 cards in total) to give one complete set of answers (A1-A10, B1 -B10 and C1-C10). Students can self-assess their answers. All combinations of answers included.
