Follow me on twitter: @ELSS_Biology. Students recap their understand of physical and chemical reactions. Teacher demonstrates chemical reaction using instant ice pack. Students carry our elephants toothpaste experiment in small drinks bottles. Students then make the reactants and products using mini-marshmallows to demonstrate conservation of mass in an experiment. Lesson is scaffolded to support the weaker students whilst stretching the more able students. The lesson is engaging with 'levelled' learning outcomes (SOLO taxonomy) and students found the lesson extremely fun.

Wow factor practical. thank you
I 'love' the elephant toothpaste - going to try this next week with my Year 7 class and looking forward to it.
This lesson is wonderful - a lot of fun for the students but also reinforces the key ideas I need them to learn.
