KS3/KS4 Calculating Weight practice problems

(0)
A set of six practice problems of increasing difficulty, based on 'weight = mass x gravitational field strength' calculations. Well-organized, model solutions are provided. Originally designed for high-ability KS3 students, this would also support the Edexcel 9-1 GCSE curriculum (Topic 2, outcomes 2.16-2.18). It is assumed that students will know g = 10 N/kg on Earth, but g values for the Moon and Mars are given in the problems. Includes the worksheet in Word, Pages, and PDF format, as well as the answer key in PDF format.

KS3 Energy Project/Assessment: Design an off-the-grid home

(0)
This activity has students apply their knowledge of concepts related to energy in designing an off-the-grid house. It can be used as a project or an alternative assessment. A suggested mark scheme is provided, as well as teaching notes, which include a sample lesson plan, and options for scaffolding or extending the activity. This was originally designed as the end-of-topic assessment for a Year 7 unit on energy. While the curriculum was the school's own, this activity will also work in the context of the National Curriculum, and could be adapted to include other National Curriculum outcomes. It could also be suitable for some KS4 students, as it touches on some of the relevant concepts (renewable energy, energy transfers), and it proved to be quite challenging for my high-ability Year 7s. Includes the activity brief and mark scheme in a single file in PDF, Word and Pages format. I copied the brief and the mark scheme front and back onto a page, so each student had the mark scheme while they were completing the assignment. Also includes teaching notes in PDF format. *** Legal stuff: Cover image of the Brighton Earthship is by Dominic Alves and is from Flickr via Wikimedia Commons (https://commons.wikimedia.org/wiki/File%3AEarthship_Brighton_Front.jpg).
