Students will read an engaging reading passage about what the skeletal system does and has a little activity called "Jumbled Bones" that has the students make a small human skeleton for their notebooks. Students will then explore, in small groups, chicken bones with magnifying glasses. The students will look at the bones for evidence of structure and components and they will speculate about purpose the bone served based on its physical appearance. Next, they will watch a short video clip about how red blood cells are produced. The teacher will follow-up with a class discussion about "How the skeletal, respiratory and circulatory systems work together to maintain homeostasis" and students will write a summary explanation in their interactive notebooks. For further elaboration, students will watch a video clip "Bones Narrated" which is a guided tour of the skeleton and its functions, and do a virtual game called "Build a Skeleton" which allows students to drag bones to create a human skeleton. Lastly, students will be evaluated on their knowledge of the skeletal system and its functions by creating a poster to present and explain to the teacher.
