Year 2's Discovering What Happens To Light As It Passes Through A Prism

Success through using SOLO to understand the Science concept of light energy.
Before each session we looked at the rubric and talked about what we would need to do to 'move up the ladder'. We would talk about what we already understood about light. I would then pose a question e.g. "what might happen if I hold a prism in the light?" and they would move off to do the experiment.
I would facilitate by asking them to describe what they see happening and prompt discussions by asking "why?"
Information was fed in through reading science texts and watching youtube clips. The children were beginning to have a great understanding about the light refracting through the glass but I wanted them to connect this to other experiments we did about refraction of light through water. 
I wrote key words from across the topic, on hexagons and arranged them on the mat. The children manipulated the hexagons. They joined hexagons together if they could make a connection. They would then explain why they had connected the hexagons. This activity gave them visual prompts to connect their ideas and extended their thinking to another context.
The children used a cause and effect map to record their thinking and had a rubric as a visual aide during writing. Their map became their planning.

Overall I feel that using the hexagons  really helped the children to connect their newly acquired knowledge (light bending through a glass prism and the colours separating) to the knowledge gained through prior experiments (light bending through water). It was as if you could see little light bulbs go on.

  1. Teaching light to early years students is tricky Jo - you have to be so careful to avoid reinforcing misconceptions - even distinguishing between a light source and a light reflector is not certain.
    You can get some ideas by downloading the primary planning documents #SOLOTaxonomy in Science Light on the NZTA curriculum portal http://education.nzta.govt.nz/resources/primary/road-safety/science

    The other resource that is great for developing students science thinking and question generating is the HookED Describe++ Map and self assessment rubric - sometimes called the exploded describe map or the see think wonder map - it helps science students distinguish observation from inference - and then helps them frame a question for further experimentation. http://pamhook.com/wiki/HookED_Describe_Plus_Plus_Map
    Happy to provide more detail on this Jo - if it helps you can contact me through my website www.pamhook.com
