This is a lesson plan that has been designed and taught to year 8 students. It is taught early in the rock cycle scheme of work and uses salol. Glass rods are dipped in the salol and drops are put on warm, room temperature and cooled (in freezer) glass slides. Crystal size is measured and compared. This model is used to make anologies with rock cooling in the real world. Feedback to my TES inbox please.

A 3 part lesson sequence on making better conclusions is suggested and a lesson provided for the 3rd lesson in the sequence - making your own conclusion on whether global warming is supported by evidence.

This is a graded task on the heart and circulatory system in format of a level assessed task used at KS3.

Student-friendly advantages vs disadvantages sheet on different fuels.

This is a series of information sheets on the 3 main species of bacteria involved in the nitrogen cycle plus an overview of the cycle itself. Pupils may highlight keywords/ phrases and use this information to create a 6 mark exam question and mark scheme that another pupil answers. 1 mark should be for quality of writing.

This is a differentiated worksheet created for lower school students in a topic on solutes, solvents and solutions. The units covered are grams, kilograms, millilitres and litres. Answers and calculation steps are provided.

This is a comprehensive list of 82 Blooms level descriptors that are printed in colour and laminated. I am putting on these on display around my whiteboard - as shown on the photo provided. Only 5 of the 6 Blooms levels are given equating to levels 3 to 7 KS3, E to A* GCSE. The top 2 Blooms levels are included together. These would work well when used with my AFL resources - see my other resources. Any feedback or suggestions? Please e-mail me at rowan.savage@hotmail.com.

This ppt forms the basis of a lesson on respiration - containing data on how temperature affects yeast respiration. The photo can be used as an image prompt to get students thinking about what they need to make break. An older PowerPoint ppt format has been added.

A loop game I created for a high ability Year 8 class

This is a lesson designed for higher ability Key Stage 3 students on solubility. The lesson starts off with a key a question about how much sugar is in coffee. This linked to a news item about a famous coffee brand that has up to 25 teaspoons (100g) of sugar in one cup of coffee. Students then consider what a concentrated an dilute solution looks like in terms of the arrangement of their particles. Finally students need to use the printed spreadsheet to calculate the concentration of various drinks and suggest what could be done to dilute them. Please rate this resource and leave feedback.

This is a level assessed task (LAT) that is used to check progress at the end of a year 8 scheme of work on inheritance and variation. The homework task on IVF and designer babies set a week before the LAT forms the research for the LAT in the classroom. Feedback to my TES inbox please.

This is a worksheet that encourages students to make their own classification for invertebrates with the beginning of a classification tree provided at the bottom of the page.

This is a lesson menu that I have designed initially for low ability pupils (levels 3 to 5) but then extended to higher ability (levels 3 to 6). It complements LOs. It can be easily modified for all lessons.

Selective breeding newspaper template plus RSPCA selective breeding poster

This document helps students and teachers track progress in A level chemistry (OCR A specification). It can easily be modified for any exam board or subject and would work well at KS4. Students record their progress on assessed homework and tests. There is space for teacher and student feedback.The 'medal&' and &';mission' comments are completed by the teacher. There is space to record intervention strategies for a particular module. For homework a percentage correct score is worked out and a grade given as follows: 60% = C, 70% = B, 80% = A.

PowerPoint for accuracy and reliability. Some slides can be printed off to serve as worksheets.

I designed and used this demo with a GCSE C-D borderline group. Vacuum pump is normally used to remove used engine oil. It worked really well to get the students interest and relate science to their world. Feedback: rowan.savage@hotmail.com

This is a lesson with grades D to B on molar gas volumes for AS Chemistry. The hook for the starter is to consider different types of fire extinguisher. Students then consider how they would calculate the volume of carbon dioxide produced from a CO2 extinguisher and 4 extinguishers that contain a solid that decomposes on heating to produce CO2. There is an A grade extension question as well as exam questions with mark schemes. Please rate this resource and leave feedback.

This is a lesson on using oxidation numbers to determine if a reaction is a redox reaction, disproportionation reaction or symproportionation reaction (opposite of disproportionation). Symproportionation is included to develop understanding and is not required by AS Chemistry specifications. The starter is the engaging visual elephant toothpaste demo. Answers on slide 17 are colour coded and animated. I have another lesson on TES where students calculate oxidation numbers. Please rate this resource and leave feedback.

This is a worksheet on atom economy and percentage yield for GCSE chemistry (grade B+) that is printed as A4 handouts on atom economy and percentage yield. There are three reactions that all make Magnesium sulphate (Epsom salt) as the useful product and so atom economy can be compared along with issues such as toxicity of waste products or reactants. The YouTube video shows how Epsom salts are used in the garden. The formula for atom economy is included. The answers are not yet included and will be uploaded shortly. Please leave feedback if this is useful or if it can be improved.
