Unit 1 Recovery

Analyze and interpret data to provide evidence for phenomena.

Students have previously identified the macro-level functions of the skin, bone, muscle, blood, and nerves, and they have figured out that the

microscopic structures (cells) in blood and nerves support the functions of those parts of the body.
In this lesson, students analyze and interpret observational data from their investigations of skin, bone, and muscle samples to provide evidence that the microscopic structures found within these tissues

support the tissue’s functions.

Unit GOAL

A middle school student injured his foot and could not walk. Over the next 4 months, the foot healed and the student could walk again.

"Storyline" and our steps to success

​>We share our experiences moving our bodies and times when we were unable to.

>We read doctor’s notes and see images of an injury.
>We create a timeline of important events that show evidence of healing.

>We develop models to show how the parts of the foot work together so the patient can walk again.

>We brainstorm related phenomena of other times we have seen healing in humans and other living things.

Key terms

​ function -- actions by the body's structures or body systems
structure-- relationship between parts of the body.
normal* -- natural state. usually refers to tests
muscle -- type of tissue (long cells) produces movement.
ligament --- connective tissue. Can connect bones and/or support joints.

orthorpedic-- medical field that works in the muculoskeletal system.
rehabilitation- help to regain movement.

Use radiation to show dense structures.
** CAT scans are 3D versions of Xrays!

X ray

Use magnetic and radio waves to find and detect different types to structures.

MRI

Multiple Select

Which structures of the body can you identify using x-rays and MRIs?

• Bones

• Muscles

• Skin

• All of the above

Multiple Choice

Which of the following machines is used to take images of the inside of the body using strong magnets and radio waves?

• X-ray machine

• MRI machine

• CT scanner

• What body parts?

• What can we identify specifically?

• How many structures/relationships can we see?

• Ankle

• Heel, ankle bones, foot bones/parts, lower leg/tibia

• [(Heel) (Foot)] + (Leg)

Draw

Identify the following points:

1) shoulder Red Dot/Line

2) neck Blue Dot/Line

3) clavical Yellow Dot/Line

4) fracture Green Dot/Line

​The waves MRIs "shoot" into the body and create a "bounce" back image or difference that makes an image. How MUCH of a "bounce" back or "pull" is what we can see.
Different types of matter create various kinds of grey on the MRI image.

MRI's and what they show:

MRIs are taken from multiple perspectives:

Horizontally <---> is called
a transverse scan
Vertically, ^v is called
a sagittal scan

​

​Get my good side!

Open Ended

How does an x-ray help us see what the inside a body? Why is an X ray helpful?

Open Ended

What is one main difference between what you can see in an x-ray and an MRI of the same body part?

​

​is a living being that consists of only one single cell, which performs all essential life functions like nutrition, excretion, reproduction, and movement

Unicellular Organisms

Organism::
the material structure of an individual life form

Uni VS. Multi

a living thing that is made up of more than one cell and whose cells work together to perform specific functions, forming tissues, organs, and body systems.

Multicellular Organisms

In OpenSci our "Middle School student" has injured their foot and it takes 4/3 weeks to heal we are learning the process the body/body systems/the tissue/the cells are doing to recover from that injury.

We are going from the "macro-" to the "micro-"

Multiple Choice

Which structures can be identified in both the horizontal and vertical knee MRIs and their corresponding scientific diagrams?

• Bone and muscle

• Skin and fat

• Cartilage and tendon

• Blood vessels and nerves

Open Ended

What new information do we get from looking at the close-up diagrams of skin, muscle, and bone?

Open Ended

What did you notice about skin, bone, and muscle from the close-up diagrams?

Open Ended

What did we figure out about how skin, muscles, and bones interact for the body to move?
