Half life - complete KS4 lesson Lesson objectives: * Do a physical practical to deepen understanding of half life and decay. * Be able to plot and explain a decay curve. * Find half lives from a decay curves. half life half-life * Notes to help the teacher. * Starter - simple task where students self-assess themselves against the objectives. * Gap fill activity - all answers are provided. * Quiz with answers. * Questions – all answers are provided. * Up and about activity. * Theory slides (carefully sculpted, interspaced with learning activities, * Practical in groups – with scaffolding text and results table blank and expected results (as required) * Equipment list – to give to your technicians. * Kinaesthetic activity – to aid recall. * Differentiated questions with answers. * Play ball * Paired work activities – answers are provided. * Scientific literacy activity. * Student self-assessment versus objectives activity – so learners can judge for themselves how much they have learnt. Thank you, and happy teaching! Yours, Barclayfox.

High quality, complete and ready to use lesson. For use in KS3 and for lower and middle ability groups in KS4. ‘‘LIFE CYCLE OF A STAR’’ - STUDENT OUTCOMES: By the end of the lesson students will be able to: * Recall space facts such as what planets, moon, stars and galaxies are * Understand new key words such as nebula, red giant, white dwarf etc. * Describe the life cycle of stars of similar mass to our sun. * Describe the life cycle of stars of much larger mass than our sun. * Compare and contrast the 2 life cycles. STARTER Pupils will start the lessons by thinking and working in pairs in a race to solve a mini quiz. After discussion of the answers this leads to revealing the title and lesson outcomes, students then self assess their current understanding of what this lesson is going to cover. MAIN and MAIN and MAIN… This lesson is chunked into discrete sections to support learning and engender positive behaviour by keeping students interested and focused. All points of the specification are addressed. There are various student activities such as: unique activity sheet, carefully selected video, paired work, literacy activities, focused questions with answers and differentiation, quiz, homework worksheet, gap fill, self-assessment and peer assessment opportunities etc. This good variety of activities keeps pupils focused and happily learning. PLENARY: In the plenary activity pupils complete an activity sheet then peer assess it to uncover how much they have learnt during the lesson. They then self-assess themselves against the lesson outcomes. Students who need further support set themselves additional homework to enhance learning of today’s lesson. EXTENSION ACTIVITIES: These are provided just in case any group requires them. OTHER BARCLAYFOX SPACE LESSONS FOR STUDENTS BETWEEN 10 YEARS AND 14 YEARS OLD: * Solar system, stars and galaxies and the universe. * Geocentric and heliocentric solar system models * Seasons. * Gravity, weight and mass. * Exploring and observing the universe. * The moon’s phases. * Eclipse * Space travel * Observations of the universe * Day and night MORE HIGH QUALITY LESSONS: For more lessons that meet the new KS3 and KS4 specifications please type Barclayfox into the tes resources search engine to see all my lessons.

This lesson is 4 in a series of 5 STARTER Pupils become engaged in the lessons by thinking/working in pairs to solve a picture puzzle to find out what today’s lesson is about. After revealing the title and lesson outcomes students self assess against their current understanding of this topic. Next there is a scientific literacy Q and A activity to ensure all students learn the key words required to understand this lesson. MAIN Homework is set and then dispersion is demonstrated by the teacher, this is an opportunity for differentiation as high ability groups can do a short practical. There is a Q and A activity to bring out the key points. MAIN Dispersion is linked to the colours in a rainbow and how a rainbow is created. The standard ROY G BIV mnemonic for remembering the spectrum is introduced. MAIN Students study a slide which shows the sun, an apple and a girl and asks them, how is it that the girl can see that the apple is red in colour? This leads to a discussion and the revealing of how some colours are absorbed and some reflected off the apple and into the girl’s eyes so that she sees the apple as red. This progresses further into what effect different colours of light has on the colours that we see when looking at objects. Students then apply their new understanding to complete an activity and peer mark their answers. MAIN Students complete a practical experiment to investigate the effect of coloured filters on the colours that they can see. Next they look at the three RGB primary colours and the effects of adding them together. PLENARY A quiz - peer marked - which uncovers how much they have learnt during the lesson. Students self assess their understanding of this topic now they have reached the end of the lesson, and compare it to their previously self-assessed understanding at the start of the lesson. Students who need further support set themselves homework. EXTENSION ACTIVITIES A variety of activities are provided just in case any of your groups requires them either this year or in future years. There is nothing for you to do but order the equipment for the class practical (simply hand your technician the printed off kit list.doc). Thank you for looking, your feedback is much appreciated! :) Lesson 4 in a series of 5. Happy teaching, Barclayfox.
