What kind of enrichment activities can i organise for 14 yr old science students? Answered



I agree with BeanGolem about the importance of collaboration. I would also suggest as general advice to let the students feel creative and in control while actually guiding them in a particular direction.

You might take a class period to discuss the interesting properties of water (teaching a bit about chemistry in the process). Then tell students to design demonstrations to show these properties. (I don't say experiments, because in school how often do we really care what the results are? ) Help them refine the methods a bit using logically but not psychologically leading questions. During your next class period, have a lab where they actually carry out these demonstrations. Finally, ask the students to prepare a lesson for next year's class. (The ability to teach the basics to someone who knows nothing about a subject is a strong indicator of how well they understand it.)

A few examples of how water is an odd chemical:
Water sticks well to itself
Water sticks well to many other things
Water dissolves many things
Water is heavy
Ice is light
Changing the temperature of water is hard
Pure water is a good insulator, but salt water a good conductor
Water is hard to boil
Water in a tube is very hard to compress or tear apart

pour hydrochloric acid into a vile, drop in some metal

put a stopper with a hose, feed the H2 into a inverted water bottle, then ignite!

You can teach about aerodynamics and have a paper air-plane contest. Take them to the gymnasium and hold a contest. You can have the longest flight distance, longest flight time, and so on. You could experiment with different weights on the front as well.

If you want them to be truly enriching, make sure they are non-competitive, relying more on collaboration.

A high school science teacher made up kits of my Quick-n-Dirty Trebuchet then held a lunch time building/throwing competition for their National Science Bowl team.

The teacher posted a comment on the Instructable telling how it was done.

The trebuchet is made of chopsticks, masking tape, paper clips, a string, a weight, two toothpicks, and 2 rubber bands. The teacher used dowels instead of chopsticks and skipped the rubber bands.

I designed it specifically to be cheap and easy to build, but it really works also. See who can make the trebuchet that throws the farthest with the best accuracy. It's physics and mechanics.

The Science team averaged 22' in the winning throws.

I'm looking forward to see what else is suggested.
