The activity I would choose to teach to junior and senior infants is activity 4: The Sun and the Shadows.
I would begin this lesson by gathering the children in circle on the floor and using the story ‘When the Sun goes Home’ as a stimulus. Using the same framework for inquiry, I would then encourage the children to think about the sun – what it is, how it helps us, what it looks like, what it does etc. I would elicit any prior knowledge about the sun and list the learning objectives using a WALT chart.
Next I would explain that the sun is a source of light and pose the question of how light can create shadows. The children can then predict how they think shadows are formed and we could put our predictions on an anchor chart. Outside, I would pair the children and allow them to see how the sun is creating their own shadow. They can then use chalk to trace their partners shadow on the ground. In class, I would place the children in small groups and encourage them to use torches and varying objects (solid and translucent) to investigate how some objects will form a shadow. The children can use card paper to create their own superhero shadow (like batman).
