Facilitation guidance from the lesson plan — what to notice in student thinking and how to respond while teaching.
Building towards
5.A Obtain information from scientific texts to describe how chloroplasts (microscopic leaf structures) respond to light (an external stimuli).
What to look / listen for
- Plant and animal cells look similar, but chloroplasts only exist in plant cells.
- Plant cells must also be alive.
- Students cite evidence from the reading that chloroplasts want a certain amount of light--not too much, not too little.
- Chloroplasts must be using sunlight somehow.
What to do
You can cue students to think back to OpenSciEd Unit 7.3: How do things inside our bodies work together to make us feel the way we do? (Inside Our Bodies Unit) if they are not remembering structures and functions in the animal cell. If students are not seeing a connection between the chloroplasts and light and/or energy, consider rewatching the chloroplasts video at https://youtu.be/tQOjO2LJGGc. Students will be able to see that light is present in the video and must be important somehow.
