I have used this resource for a practical investigation in Science Week. It is suitable for Year 1,2 or 3. This resource includes a Powerpoint to support the teaching and the Investigation write up work sheet. The Powerpoint supports the writing and is editable to suit your class needs. I worked through each stage together, modelling each section and then letting the children have a go. It is a practical investigation about woodlice and their prefered habitat. I suggest you collect the woodlice before your lesson, approximately 20. Easy to find under rocks, logs and in dark, damp places. The only other thing you need is a large container to begin your experiment. I used a large Tuff Tray. The whole resource is pretty self explanitory and it is an interesting investigation for KS1 and LKS2. I have used it previously in an observation and it has got very positive feedback.
