Sellotape and newspaper are free – but straws are 1000B a straw. The bridge must be wide enough to support a weight and the stronger the better! Resources are: straws, newspaper, sellotape. Set up the challenge – each group must build a bridge to span a 1 metre gap.
What are the advantages and disadvantages of each of these? Brief discussion about force dissipation – which shapes do this well? Use the bridge building game to discuss strategies.ĭiscuss the different types of bridge structures – plain bridge, arch bridge, suspension bridge. Watch Youtube video interviewing 3 young structural engineers: Learning Objectives: Students are introduced to one of the many careers that they can pursue through mathematics.īrainstorm – why is mathematics useful for engineering? What kinds of jobs do engineers do? (refer to maths careers site – a large number of well paid jobs are in engineering) If you liked this post you might also like:Įven Pigeons Can Do Maths A discussion about the ability of both chimps and pigeons to countįinger Ratio Predicts Maths Ability? A post which discusses the correlation between the two. Then rewinding the video to the start – and as if by magic she had changed direction. If they can’t (I initially could only see this going in an anti clockwise direction) near the end of the video it shows the woman rotating in a clockwise direction to help. Some will be able to switch between the 2 views.
Any plans for mathstudio download#
The promo codes provided let you download the paid version for free. MathStudio also works completely fully-featured free in your web browser which Mathematica also does not offer yet. They have to stare at a rotating woman – some students will see this going clockwise, others anticlockwise. Mathematica has yet to release an iOS version and MathStudio is a great alternative. The last one is a good test of whether students are “right brain” or “left brain” dominant. You have to set this one up so that all students are really intently concentrating on the screen – perhaps a prize for the student who gets the answer correct? Also no talking! Students have to count basketball passes: The third video is even more impressive – though it doesn’t work on all students. This is also a great way of showing how we often fail to see what is really in front of us: The second one is the amazing colour changing card trick by Richard Wiseman. This is a really curious experiment that shows that what we “hear” is actually often influenced by what we see.
The first one at the top of the page is the “Fa, Ba” test. Then look at how the data could be collected in a larger scale experiment (or how the experiment could be modified). They also have a nice link to ToK – how can we believe what we see or what we hear? To what extent should we trust our senses? And it shows the power of statistics and empirical testing in trying to understand what is externally real and what is our own version of reality.įor each one, have the students make a hypothesis (if possible without giving the endings away!), then collect some data as to how the students react. These topics are a great way to add interest to statistics and probability lessons at KS3 and KS4 level, and also a good example of investigations that IB students can conduct.
