Why choose this resource? It has easy to follow instructions that individual groups of students can use to extract DNA very successfully. It also has questions suitable for A level or Higher Biology students or a "good" class of Biology Triple GCSE students. Practical guide would be very useful for non-specialists.

Students have to work out which children have cystic fibrosis and how they have inherited it from the symptoms and other information given on the sheet. Could be used as an assessment of student's understanding.

Bioaccumulation This power point gives an increasing number of clues to help students work out why people died in the disaster at Minamata. (Bioacccumulation of mercury in the food chain.) My top set Yr 8s enjoyed the challenge.

This is for Edexcel A level Biology context-led course. There is information and questions to answer including an exam-style question. I have used and modified some slides from hmc keating's power point on this topic ( on the TES website), and have added some more to suit the teaching of the Edexcel course. Thanks to hmc Keating. The blog link has a little etra about the Red Queen theory of evolution.

This is for KS3 students to give them practice at collecting and analysing data. It proved to be very effective with a mixed ability group of Year 7 students. Although there is just one document there is enough here to keep a class busy for an hour and they are practising maths skills essential to science and some scientific skills as well

Used for old BTEC genetics and with GCSE to teach natural selection. Students can sort cards in order to check their understanding.

For AS SNAB Biology. Follow up to a group practical by the class on the effect of temperature on the diffusion of dye from beetroot. Main aim was to evaluate the data and consolidate knowledge and application of terms accuracy and reliability( reproducibility as well?) There are questions to answer on the power point. Eventually this AS class will need to evaluate their own practical coursework at A2.

You can use these to: shuffle and ask pupils to sort them into pros and cons. ask pupils to rank them in order of importance. string a 'washing line' between 2 clampstands and get pupils to position them in rank order of importance/ reasons for and against. Use pegs.

This was used with a low-ability Yr 10 group for GCSE work. Could be adapted for other groups/KS3. Also useful for assessing ability to analyse scientific results.

For Biology content of new BTEC Level 3 applied Science. Practice questions about Gram positive and negative bacteria.

The topics here are action potentials, synapses and COPD. These are worksheets designed so students can do some independent research either in class or for homework on some aspects of the biology part of unit 1. Could be used as revision tasks,

This is a worksheet for students to analyse data from Van Helmont’s investigation. It can be used as an introduction to photosynthesis or as an exercise in understanding the scientific method. The unique feature of this is information is given from the original writings and teachers have found this gives an extra stretch and challenge to the problems set. More questions than those given can be added. Could be useful for KS3 or KS4. I have just added a link to a video which gives the background to his investigation and has notes on the video from the Science and Plants for Schools website.

This resource tells you how your students can see some stunning pictures of stomata, without using that fiddly nail varnish! It also has questions which test the student's understanding of the function of stomata, scientific method and the link between decrease in stomatal density and global warming. Suitable for KS4 and possibly useful for KS5.

For Edexcel A level context -led approach. Suitable for concept -led? Could be suitable for some parts of other A level boards? My Yr 13s found the 'do cars make us fat ?' interesting.

A science Christmas quiz based around the plants and animals we associate with Christmas. Suitable for higher end KS2 and KS3 as an end of term activity. It looks at adaptations, classification and even science methodology so it reviews topics and has a bit of end of term Christmas fun.

This covers use of respirometers and the advantages and disadvantages of different types. Has questions as well as information. For Salter-Nuffield Edexcel (context approach).

For Nuffield-Salters Edxcel A level Biology Topic 6. Power point has questions on it to help students review their work.\nCovers the symptoms and progression of the disease.

This power-point contains information and questions to revise about two-thirds of topic 4. It follows the checklist for Topic 4 and is unfinished. I will try to get it finished and put the rest of it up - but it should be useful for most of topic 4 if anyone wishes to try it

Easy to view root hairs, xylem and stomata from the easy to grow cress! Ditch celery and other favourites - this works very well. Please go to the BlogSpot on the resource 'Using Cress seedlings....... as it has photos you can use.

This was written as a leveled assessment task for low ability Year 8's. The students enjoyed doing the tasks on the sheet and as they wanted to do it they read the tasks! It could be adapted for higher ability - it goes to level 6 anyway.
