Your child can identify force examples by checking the pictures. There are 8 images of kids engaging in activities and objects in motion. Get them to name the activities and objects, or if they know, explain force and interaction.
Teach your students about shadows with this printout. Ask them to check off the boxes next to the pictures that create a shadow. Explain that some objects block light, forming a shadow, while others don't and thus don't create a shadow. Your students are likely already familiar with their own shadow.
