Overview - Human Body in Motion

  • This unit will give students a view inside their bodies to see how they move. Students will discover that movement, like all bodily functions, requires many parts of the body to work together. They will explore the skeletal, muscular, nervous, circulatory, respiratory, and digestive systems to uncover the specific role each plays in bringing about movement. They will come to appreciate the complex intricacies and dependencies between parts of their bodies and learn what they can do to maintain and protect these parts.

Cluster 1 - Mechanics of Movement

  • Overview

    We will focus on three systems most directly involved in moving the body: the skeletal, muscular, and nervous systems. We will learn that muscles move at joints and that the design of these joints affects the ways various bones can move. We will construct arm models to discover how the muscles that move the body often work in pairs. We will also discover that the nervous system controls the muscles that move the body.

Cluster 1 - Lessons

  • LESSON2 - Where do Bones Move?

    Big Idea: To move, many partsof our bodies must work together. Muscles move our skeletons by pulling onbones that meet at joints.

    Lesson Goals

    ·  Discoverthat the skeleton can move at joints – the places were two or more bones meet.

    ·  Learnthat several types of joints, each with a different structure.

    ·  Understandthat the structure of a join affects how its bones can move.
     
     

    LESSON3 – Moving Our Bones

    Big Idea: To move, many partsof our bodies must work together. Muscles move our skeletons by pulling onbones that meet at joints.

    Lesson Goals

    ·  Learnthat muscles move the bones they are attached to by pulling on them.

    ·  Realizethat two muscles are required to bend and straighten a limp

    ·  Developa model to show how muscles work in pairs, pulling on bones in turns, to bend andstraighten a limb.
     
     

    LESSON 4 – How Our Muscles Know When to Move

    Big Idea: To move, many parts of our bodies must work together. Nerves carry signals to our muscles to move parts of our body.

    Lesson Goals
    ·  Discover that the senses, brain, and other parts of the neervous system work together to signal muscles to move.
     
     

    LESSON5 – Moving Quickly to Prevent Harm

    Big Idea: To move, many partsof our bodies must work together. Nerves carry signals to our muscles to moveparts of our body.

    Lesson Goals

    ·  Thenervous system sometimes causes muscles to move without an intentional decisionby the brain and appreciate the protective nature of these movements.

    ·  Recognizethe differences between reflexes and intentional reactions.

     
     
     

Cluster 2 - Body Basics

  • Cluster 2: BodyBasics

     

    Overview

    Studentswill learn how the human body is “put together” or organized. They learn aboutthe needs of cells, specifically bone cells and muscle cells, and gain anunderstanding of the structure of bones.

     

    Extra Credit

    1. Calculate how many years it would take to count to 50 trillion – the approximate number of cells in the human body.
    2. Research discoveries relevant to cells – at least 5 facts.
    3. To help build strong bones, you need to have enough calcium in your diet. Bring in a recipe containing that includes foods that are high in calcium.
    4. Research diseases of the muscles: carpal tunnel syndrome, muscular dystrophy, or polio.

Cluster 2 - Lessons

  • Lesson6 – Inside Bones

    Big Idea: Bones are made ofunique cells important to movement. TO produce energy and function properly,all cells need a constant supply of oxygen, nutrients, and water.

    Lesson Goals

    • Discover that bones function properly if they receive nutrients and care.
    • Examine and describe the tissues found in bone.

     

    Lesson7 – Working Muscles

    Big Idea: Muscles are made ofunique cells important to movement. To produce the energy needed for movement,muscle cells need a constant supply of oxygen, nutrients, and water.

    Lesson Goals

    • Discover that muscle cells need energy to move the body and get tired when they don’t have enough.

     

    Lesson11 – Building Blocks: Cells Make It All Possible

    Big Idea: The human body ismade up of many different types of cells. Each type of cell has uniquecharacteristics for performing a specific “job”.

    Lesson Goals

    • Identify the variety of cell types in the human body.
    • The functions of body parts are related to the types of cells that form them.

Cluster 3 - Supporting Active Muscle Cells

  • Cluster 3: SupportingActive Muscle Cells

     

    Overview

    Wewill focus on how three systems – the circulatory, respiratory, and digestivesystems – support the muscles and bones. The circulatory system delivers oxygenand nutrient-rich blood that muscle cells need and carries away their waste.The respiratory system delivers oxygen to the blood and removes carbon dioxidewaste from the blood. The digestive system takes in food, digests it, andpasses its nutrients into the blood.

     

    Extra Credit

    1. Determine the amount of time it takes the heart to return to a normal resting heart rate after exercising.
    2. Use a cardboard tube to listen to a partner’s heart beat.
    3. Investigate disease of the circulatory, respiratory, and digestive systems.

  • Lesson 8 – Delivering What Muscles Need

    Big Idea: To move, many partsof our bodies must work together. To produce the energy needed for movement,muscles cells need a constant supply of oxygen, nutrients, and water.

    Lesson Goals

    • Discover that the heart pumps faster when the body is more active.
    • Recognize that the heart pumps blood containing oxygen, nutrients, and water to the body’s cells.
    • Realize the heart also pumps blood containing cell waste away from the body’s cells.

    Lesson Goals

    • Become aware that breathing delivers the oxygen needed by muscle cells, and all our bodies’ cells, to the blood.
    • Learn that breathing also removes waste (carbon dioxide) from the blood.
    • Appreciate how much we depend on a healthy respiratory system

     

    Lesson10 – How our Muscles Get the Nutrients They Need

    Big Idea: To move, many partsof our bodies must work together. To produce the energy needed for movement,muscles cells need a constant supply of oxygen, nutrients, and water.

    • Realize that food must be digested before it can pass into the bloodstream.
    • Reinforce that muscle cells (and all the body’s cells) need nutrients so they can produce the energy they need to do their “job”.
