Katherine Brou Science Lesson Plan Objectives •
TCW increase his/her understanding of what happens when light hits different objects.
Higher Level Thinking Questions • • •
Why do you think a shadow forms when light hits an opaque object? What would happen if you shined a light on something with holes (like a basket)? If a window is an example of a sheer object, do sheer objects allow light to pass through them?
•
If you didn’t have a flashlight, how could you show what occurs when you shine light on an object?
Lesson Procedures •
Review what is known about light so far and reintroduce the terms opaque, transparent, translucent. (Can use PowerPoint) have a good discussion with details and examples.
•
Explain to children what we are going to do with this experiment very explicitly showing them an example and stating what to do when done with exploration. o Use 1 color x or check for predictions, and another color for actual result.
• •
Allow children to explore materials with flashlight. When a group finishes their exploration, give them the higher order thinking question cards appropriate for their level to discuss.
•
Come back together as a class to discuss findings. Have children talk about the different objects, what they were, and why/how they discovered this.
•
If there is time, bring in new examples and ask children to predict and then explore together (1 for each category)
• •
Go over some of the question cards and discuss them… Introduce the scavenger hunt and explain to children that it is not homework but a fun activity for them to do with their family/parents if they choose. (Can be fun to teach them what you know!)
Assessment •
TTW assess a child’s understanding of what happens when light hits different objects (opaque, transparent, translucent) through observation and anecdotal records.
