First of all we looked at the materials and discussed their properties, were they thick or thin and did they look like they would block the light (opaque)?
We then made our predictions based on our discussions.
We carried out the investigations according to our methods. Each group had a different way of making measurements.
Everyone got involved, the groups worked completely independently.
A completed table of results.
There were a few surprises in the results tables, however we all managed to link our predictions with our conclusions. A great investigation, well done Year 6.
