In
pairs you must prepare a brief, entertaining science demonstration that will amaze
your audience and explain a science concept to them. Your
presentation cannot be dangerous and you cannot use bicarbonate soda. hehehe Some
of my favourite demonstrations are: The
Floating Teabag Alka
Seltzer Rockets - I do these without the cardboard. Steve
Spangler's site is a great place to the students to start looking but you
can read books, explore the Internet or talk to people about their favourite science
activities.
Extension - perform these presentations for another class. FYI
- As a teacher I've found this a great way to increase your repertoire of great
science lessons with the students doing all the legwork for you :) |
