This was used as a lesson for KS3 Year 7 'Space' unit from Activate 1, as an introduction. I have also used it for a 'end of the year' fun lesson for year 8. Includes videos and websites, tasks and activities.
It is intensive and was designed for sparking interest for top set.
Could definitely be taught off the cuff for any science teacher.
Lesson to follow Activate textbook, year 8 Recycling
Includes fill in the gaps task sheet, advantages and disadvantages table and an example equation.
If you are using the kerboodle tests be aware that the equation I have used looks like the one on the test for HT, and this caused a bit of confusion for some of my students.
Did this with top set but as it is a quick lesson I managed some revision at the end, so have included revision slide at end. Will need your own exam questions for the task - just took mine off of exam pro but obviously every class is different. Can send out if needed.
