Instructions to make your own model of the lungs and student worksheet. Identify the key parts of the respiratory system (Students will confuse this with respiration so avoid using this word), Describe how the diaphragm is used for gas exchange and how gasses diffuse at the alveoli. Items needed for model lung: Clear plastic cup each (1 pint), Straws (preferably thick), Elastic bands and lots of standard balloons, screw driver.

Nutrition lesson for Teachers or Health Professionals. Raise awareness about poor food choices through a nutrition survey and highlight healthy diet choices. Food labels and worksheet to teach' reading food labels'. Familiar food labels to supplement labels bought in and for use in ranking foods by nutritional qualities.

Requires Microsoft PowerPoint. 150 Multiple choice questions from the new specification. If Macros are enabled when prompted at the start of the presentation, the powerpoint will mark itself and give feedback (topics of weakness and more specific question feedback). Could be used at the start and end of the year to measure progress. Students can print results on slide 52 and use the feedback for independent learning or homework. I hope this saves you lots of marking. I have included hard copies of the questions and answers in case the ICT lets you down or you want to use it for a cover lesson.

A PowerPoint with supporting instructions, starter and extension activities. Best if you use tealight candles. Encourages students to consider variables and to make accurate measurements. Students draw a graph to show their results. If students are difficult to motivate then ask them to estimate how long a candle would last in a specific volume (i.e. 300ml beaker) which they will have to produce a graph to extrapolate or interpolate to find this out. You could test a 300ml beaker at the end to test this. The extension activity promotes higher level scientific thought. It is unknown if the carbon dioxide smothers the candle or if the oxygen runs out first. Most students will say the taller candle as this will last longer!

Students are introduced to the different microorganisms and their contrasting structure. Students compare the scale of the microorganisms to familiar objects. Students will then research the microorganisms further and present their findings scientifically (using one of 6 randomly selected scientific formats).

Cross curricular activity involving English persuasive writing, comprehension, scientific investigation and data analysis skills. Students will debate the use of plastic packaging. Both sides of the argument are presented and the teacher can decide if they choose. Ideal for cross curricular (also citizenship and fund raising) or even a one off cover lesson. Requires printing of colour data sheets (3 A4 per group). Supporting PowerPoint with prompts. Lesson plan. All proceeds will go towards The War on Plastic fund:

Powerpoint online not supported A PowerPoint based assessment consisting of 50 questions from the new Spec. If Macros are enabled the quiz is self marking and give feedback based on weak topics and areas for improvement. Ideal for end of year assessment to identify areas of weakness or gaps in knowledge. May be delivered by a non specialist in an ICT room and answer sheet is included to support them. Students could research the topics suggested when they have finished the assessment. Also available: Physics and Chemistry see my shop Discount for buying as a Bundle.

The presentation considers the adaptation of Villi to perform their role. Investigate how the structure of Villi make it effective at absorbing water and nutrients. The worksheet explores digestive enzymes and assesses the students understanding.

A simple activity to model cloning and genetic engineering using Haribo starmix. Student instructions are included. May also wish to buy some flumps. Ensure lab is clean and advisable to wear gloves. I found the smaller Haribo starmix bags to be better as the students can handle these. Must check there are two eggs or have a supply of spare eggs. Get students to describe the process back to you as a plenary. Enjoy.

Transcription and Translation activity simplified for low to moderate ability or high ability starter activity. Turn a strand of DNA into a sequence of Amino Acids then translate these into a protein. Extension activity explores the effects of mutations and the beneficial or limiting effects of this. Students could explain what they have done for a plenary.

Starter worksheet identifying the body's senses. Extension activity linking animals to their heightened senses. Practical activity requires two pronged hair pins and worksheet provided.

Tape the sheets to a small box (dice). Students choose a topic and roll the dice to determine how to present their information. Adapt slide two with your own topics.

Question of sport number round style Quiz. Answer 3 key points from each topic image. People tend to recall facts and key information in 3's so it promotes memory. Can also be carried out as a test where students will not see the answers (using the test version included in this sale). The students could then self assess using thee quiz version.

6 PowerPoint files each containing a tutorial on the 2018 spec most difficult topics including sample exam questions. This can be delivered as a lesson, a self guided revision activity or ICT cover lesson. Ideal for tutoring students online. Topics include: Limiting Reactants, Modelling the Atom, Homeostasis, Electromagnet, pressure and Excretion in humans. Links to the solo taxonomy to ensure progress is being made and new spec exam questions to assess student progress.

Revision in pictures covering the iGCSE Cambridge Spec. Recall and make links between topics. Microsoft PowerPoint.

Starter for nutrition. Uses of nutrients.
