LESSON TITLE: Dem Bones
CURRICULUM AREA: Science
GRADE LEVEL: 6-8
OBJECTIVES: 4.01 Identify the skeleton as a system of the human body
ESSENTIAL QUESTIONS: How many bones are in the human body? Time:one 45-minute periods Materials:
Per Student Group:
diagram/poster of human skeleton sections (torso, arms/hands, legs/feet,
skull) See examples in lesson. Per Class:
overhead/chart of class data table
Process Skills: Observe, Communicate, Predict, Measure, Classify
Engage: Ask the students to recall how the body moved. Ask the following questions: Do your bones move when you jump? Where are your bones? How can you tell where your bones are? Have students feel for the bones inside their bodies. Ask if they can feel all of the bones in their bodies. Explain to the students that they will conduct an investigation that will help them to determine how many bones make up their skeleton. Have students predict how many bones total they believe are in the human skeleton based on what they have felt in their bodies.
Explore: Divide the class into four groups. Provide each group with diagrams of two human skeleton sections. For example, one group may receive the skull and torso, another group will get the legs and arms, etc. Students should use the diagrams to count the number of bones in that section of the skeleton and record their conclusions in a data table like the ones below.
