Lesson Question What we found out: Lesson 1 A student who was previously able to walk was injured in an accident and could no longer walk. What happened in the More than one part of the patient’s foot was injured in the student’s foot so they could same accident. walk again? Some of the injured parts of the foot needed outside supports during the healing process. Over time, the injured parts of the foot were able to heal; some took longer than others. The injury caused gaps between the damaged structures in the foot. Lesson 2 Skin is attached to the muscle underneath it, and the muscle is attached to bones. What do our bones, skin, Bones move when the muscles attached to them move. and muscles do for us? The muscles and bones are both parts of the wing (or foot) system and interact for the wing (or foot) to move. When one part of the system is broken or injured, the whole system is affected and can’t function the way it used to. Lesson 3 There are blood vessels in the different parts of the bone, muscle, and skin. How can medical images and There are nerves that run through the layers of the skin, diagrams help us figure out muscle, and bone. more about the structures in our body? Lesson 4 As a whole, the blood’s function is to travel around the body carrying the things the body needs. Why is there blood in all of The blood’s flowy liquid nature (structure) allows it to these places in the body? perform its function. The blood vessels are structures that allow blood to move throughout the body. Blood is composed of a mixture of components that we cannot see without a microscope. Blood is made of red blood cells, white blood cells, platelets, and blood plasma. The structure of blood cells relates to their function: their round shape helps them travel easily through the tubular blood vessels. Platelets’ structure relates to their function: their branching arms and stickiness help them plug damaged parts of the blood vessels to stop leaks. Lesson 5 There are nerve endings in skin, bones, muscles, and other parts of the body. What do nerves do, and why Nerve cells have a very unique structure--they have long, are they in different parts of thin “branches” or “tentacles” that extend from the center. the body? Nerve cells connect to other nerve cells, forming a network of nerves that carry signals between all parts of the body and the brain. The structure of nerve cells is perfectly suited for their function--they branch out and connect different parts of the body so that they can carry signals between the body and the brain. Lesson 6 Bone, muscle, and skin have repeating patterns of microscopic structures called cells. What will we see if we look The unique structures of the cells that make up these at skin, bone, and muscle different parts of the body are related to their function: with the microscope, too? Bone cells form ring-like patterns close together to provide structure and strength for the body. Skin cells squish together to create protective layers that keep things in or out of the body. Muscle cells are long and stringy so that they can stretch and contract, allowing parts of the body to move. Many cells work together to form tissues in the body. Structure is the characteristic of something (the shape or way it’s made or arranged) that supports its function. Lesson 7 Microscopic samples from living things that we analyze are made of cells. Are all things made of cells? Microscopic samples from things that were never living are not made of cells. Lesson 8 New skin cells form from existing skin cells at the site of the injury, causing the wound to get smaller and smaller. What happened as the skin on top of the foot healed? Lesson 9 I can analyze and interpret data from a video and microscopic images at varying spatial and time scales to What is happening at the conclude that new cells come from old cells following a site of an injury to fill the predictable pattern of repeated steps. gap? New cells come from old cells, which grow and split through a repeated and nonrandom process. When cells grow and split, they make new cells of the same type (e.g., skin cells make new skin cells and bone cells make new bone cells). When a gap in the skin, muscle, or bone is filled by new cells as a result of cells growing and splitting. Lesson 10 Cells need food to make more cells. Cells grow more and make more cells if they have access to What do cells need to grow more food. and make more of there are single-celled (unicellular) and many-celled themselves? (multicellular) living things. Cells are living things. All living things are made of cells. Lesson 11 Plant cells have a cell wall and a cell membrane. The cell wall is a structure that is unique to plants and helps How do cells get what they the cell and the plant maintain its shape. need to grow? The cell membrane and cell wall are structures that act as barriers and allow things the cell needs (food, nutrients, etc.) or does not need into or out of the cell through tiny openings. Lesson 12 The body reacts to an injury by swelling, which increases blood flow and brings extra fluid to injured tissue to help it How do the structures and heal. systems in the body work The healing process for the foot is similar to how other body together to heal the injury? parts and other living things heal as well. Lesson 13 Children have growth plates in their skeletons which are gaps between their bones. How is the process of The process that occurs when a person grows is similar to growing similar to healing? healing because cells fill a gap in each tissue/body part as it heals (or grows), and the same structures and systems that are needed to heal, are needed to grow. Lesson 14 A person could be healed, but that part of the body may have a different function than before.
