Publications Starting points For preview purposes only.

This activity follows on from the classroom based one discussed in ‘Living or not?’. 1. Children need to revise the indicators of ‘living’ or ‘non-living’ they decided on before attempting the observation exercise during the walk in the school grounds. 2. The most useful approach would be for children to have an observation sheet on which they could record examples of the two categories. Some of these could be transferred in graphic form to the worksheet on returning to the classroom.

www.readyed.net

Post-Use of Activity Page Follow up discussion should emphasise the ‘living’/‘non-living’ indicators as applied to objects observed on the walk.

1. Remind children of the previous activity involving the application of heat. What effectively causes the structure of objects to change? 2. Prepare the children for the activity by discussing in general terms “What happens to sugar when you put it in your Milo or hot drink?” i.e. Does the sugar simply disappear or does it take another form? (Other form.) How do you know it is still present? (Taste.)

www.readyed.net Post-Use of Activity Page The final activity, as the worksheet asks the children to describe another investigation which could show how materials or substances could change. They will need assistance to complete this section. Perhaps the most viable suggestion could be the basis for the next lesson, or for a demonstration by a chosen pupil.
