Dear Clare
Apologies for delay.
A good one is making a hot air balloon with different groups cutting out different panels or measuring different cords.
 
Most 'make a hot air balloon' activities don't work because:
-ordinary paper is far too heavy.
-string is far too heavy.
-sellotape is too heavy.
-the balloon is far too small (think BIG Science) and therefore does not enclose a large enough volume of air.
 
Good materials are:
-very large sheets of tissue paper.
-cotton sewing thread for the 'ropes'
-paper glue where the glue will get lighter as it dries.
 
Sadly, this can't be built and flown in the same day because wet glue is too heavy to fly. The flight would have to be back at school.
A template may exist on the www.
Try some of the teacher's resource websites
Hope this helps.
Regards
Chris

Subject: Really BIG Science!

 

Hi all

 

Does anyone have any really good tried and tested ideas for really BIG science activities – in other words, moving away from ‘table top’ experiments and investigations for a couple or so children to ones which perhaps involve large groups or the whole class – maybe which the teacher can make/arrange beforehand or which the children can create themselves.

 

Could be based on any science theme – just trying to think outside the ‘cardboard box’ (hmmm, cardboard boxes, must be something which will involve those . . .)

 

Many thanks
