HOVERCRAFT mixture of designs

Here are some students ( STEM Club ) making hovercraft.
From early development work we have improved the designs
to reflect some ingenious thinking.

AN INTERESTING 3 MOROR ARRANGEMENT

GOOD EXAMPLE OF THINKING DIFFERENTLY.
SOME BALANCE PROBLEMS - BUT EASILY EVALUATED AND SOLVED - GOOD JOB.

Making FOOTBALL robots

Good little kit - provides all parts needed except battery. Can be challenging to assemble - but rewarding.
Pictures below.

Torch..ing stuff at BGS

This useful kit makes two torches. One of which uses a membrane switch.

Wednesday 24th June just before JG birthday

Well what a wonderful session. All the staff were impressed with you all. The rockets made us think about extension work and we are planning a follow up next week. PLEASE NOTE we need to meet on MONDAYS for the next and last 2 weeks of this years programme. Did you look up "para"?
Photos soon.
Is it YOUR birthday ... I heard someone say (o)

Looking at rockets. Pictures soon

These pictures show boys making stomp rockets - previously they had made small rockets which used a straw for propulsion via a good exhalation of air.

Marbles passing from tower to tower

This session introduced the notion of harmonics, frequency, oscillation, triangulation and, of course, solving problems. We talked about the Tacoma Narrows bridge failure , particular thanks to Mr. Hamshaw and we looked at a glass being broken with sound.
Homework - go home and try singing to a wine glass ... loudly and highly pitched... or simply run your finger lightly around a slightly dampened rim of a wine glass.. you s
hould hear the harmonic evidence of ocillating frequency. See video here, http://www.youtube.com/watch?v=ECNDpCYvaOc

Next meeting not until 5th May - happy Easter form Mr. Geekie and the team.
