This topic is for posting feedback from teachers on the low-tech kit, from the testing in different countries.

Feedback from Norway
« Reply #1 on: Mon 2009-02-09 19:30 »
Here's a list of the first comments from the Norwegian teachers on the contents of the low-tech kit (from the meeting on 3 February 2009):


Experimental materials / equipment / box design

  • Induction flashlight must have rod design, not the current rotational design
  • Need more and longer wires with crocodile clips already attached. Preferrably different colours
  • Need two sets of yellow/purple ring magnets and a longer non-magnets (e.g. wooden) stick of the right diameter
  • Pyrolitchic graphite must be smaller and thinner so it can float (or we need instructions on how to cleave and cut it properly)
  • Aluminium tube for falling magnet experiment
  • Aluminium and plastic slabs for sliding/rolling magnets (so can show similar effects as in tubes)
  • Additional copper slab - same mass, twice the width and half the tickness, for comparison and calculations
  • Iron filings must be smaller, the big ones do not work properly. Or we need instructions on how to use them to understand why they are included
  • Magnets MUST be packaged in protective padding and stick in boxes, now they easily fall out and clash, also very difficult to get apart when they are "stuck together" - both large and small magnets, since the small ones are difficult to get a grip on.
  • "Geomag sticks" are too weak, need stronger magnets.
  • Include "electromagnet" with different number of windings - to be used as transformer (this is also in the modules)
  • Include more alimunium "wheels" as they eaily break - hole must be exactly in the middle and circular, not rectangular
  • Need protective goggles for flying magnet splinters when these crch (and they will)
  • Adjust box so that all items fit tightly and do not fall out easily
  • If possible, consider packaging materials that belong together for one experiment in separate boxes (see also below for listing equipment to be used in each experiment

Support materials

  • Number of windings in the different copper coils should be listed, so it is possible to calculate forces
  • Iron filings must be smaller, the big ones do not work properly. Or we need instructions on how to use them to understand why they are included
  • Security note for magnets must be clearly placed on box, in teacher guide and all other relevant places
  • Detailed list of which materials go with which experiments, preferrably with photos, must be included in teacher guide for all experiments
  • Number of materials should be considered so it is possible to run experiments simultaneously when different experiments require the same equipment. Or, different combinations of experiments can be listed in the teacher guide (where they do not overlap in the use of equipment). This is necessary for organizing testing in a classroom using e.g. different stations with different experiments (since there is not enough to run the same experiment in several parallels


Looking forward to more comments!

We need to collect and analyze this feedback in order to improve the next version.

Dear MOSEM partners,

please post your feedback on the Low-Tech kits here - we need to determine which experiments (content materials) to keep for the next version ASAP, so that Simplicatus can start working with the suppliers for these materials.

It was decided in Ostrava that the deadline for making this list was 1 August. Due to vacation we can extend this deadline to 15 August. I ask you to respond quickly to this.
