A great idea for an end of unit project in Gr. 4 habitats and communities.
Have students create a poster about a habitat of their choice. You can decide what information the students will have to share based on their learning in the unit (ex: adaptations in that habitat, why they need to be protected, etc.). Once posters are complete, they can program Dash to travel around their habitat to different areas. Once it arrives on the desired location, students share that information with their peers.
