This exercise describes examples of positive and negative feedback loops in biology. Students look at each example and: a) decide if it describes positive or negative feedback b) summarise the process in a flow diagram

A sheet covering the main topics in the new AQA C1 unit

This is aimed at edexcel A level biology but may be relevant to other boards/subjects. I've taken common command words from exams and have attempted to explain their meaning through this activity.

This is an alternative worksheet to accompany the resource at http://www.tes.co.uk/teaching-resource/How-Science-Works-The-Simpsons-Investigation-6205917/

A sheet covering the main topics of the new radioactivity topic for AQA.

This is a homework or independent research task where students use the website given to locate the information. It summarises properties of diamond and graphite, and included fullerene and nanoparticles.

This sheet is completed on computer. Students open the document and complete the sheet. Press ctrl and click on the links to open the websites.

A useful starter for B4 created for an interview lesson (hence the AfL) - how scientists' ideas about photosynthesis have developed. Get three students to read the pieces about each scientist and the class fill in their sheets after each one.

Students arrange the cards on the template (print on A3) - there are some extras to make it a bit harder.

A worksheet for A level biology which summarises the processes of transcription, post-transcription modification, translation and the nature of the genetic code. Examples are given for the students to illustrate the role of the coding strand, template strand, mRNA and tRNA. Answers are provided on a separate sheet.

As much revision as I could fit on a single page! Includes: key words, states of matter, change of state graph, melting and boiling points.

A websheet to support student research into metal extraction. Upload this to your VLE and students complete and print for their notes. They need to press ctrl and click the links to open the websites.

I couldn't find a decent summary anywhere so I made this worksheet. I don&'t think students need to know too many details for AQA Unit 1 so hopefully this will be useful. Please let me know if I&';ve missed anything or made any mistakes.

I adapted this from another TES resource - I added some blanks for students to fill in and edited to reflect our C1a unit.

This is suitable for end-of-year revision for weaker students. Instructions: BEFORE LESSON 1. Print out the posters on A3 2. Print out the worksheets 1 per pupil 3. Print out the cards, cut out and put them on desks along with the corresponding poster DURING LESSON 1. Give out worksheets, students move to different posters/cards 2. They arrange the cards on the poster. When it has been checked, they copy this onto their own worksheets.

This is an ICT based investigation using Multimedia Science School (http://mss.lgfl.org.uk/BL612/ls.html) - ignore the comment below, you don't need a username. Students record results on the Word document and can do data analysis on the Excel document.

A worksheet for students to practice drawing ionic bonds

Starter or plenary comparing different methods of transport. Answers included on separate sheet

The first page is a worksheet for students. The other pages are for research - print out a few copies which students can pass round and complete the relevant rows on their table.

Instead of drawing hundreds of electrons, this resource presents the electron arrangements for the first 20 elements which students first identify, then arrange onto their periodic table. Much neater, and less chance of mistakes. Print out SINGLE SIDED so students can cut out the cards on page 1 and arrange them into the periodic table on page 2.
