The letter of the week this week was 'M' so we looked at:
Moving Magical Marbles
with More Momentum than Most
We set up 2 metre rulers on a table - just wide enough to make a track for marbles to run along. Then we placed 1 marble on our track. We put another marble about 10 cm further along the track and flicked the first marble along to hit the second one. When they hit, the first marble stayed still and the second marble started moving.
We then tried this with different combinations
- 1 marble hitting 8 = the last in the row of 8 moved
- 2 marbles hitting 5 = the last 2 in the row of 5 moved.
The marble that had been rolling stopped while the one
that had been still rolled! The momentum of the rolling marble transfers to
the other one, stopping the first and setting the second in motion.
