The Skeletal System: Crash Course A&P

(View Complete Item Description)

Crash Course AP Science: Today Hank explains the skeletal system and why astronauts Scott Kelly and Mikhail Kornienko are out in space studying it. He talks about the anatomy of the skeletal system, including the flat, short, and irregular bones, and their individual arrangements of compact and spongy bone. He'll also cover the microanatomy of bones, particularly the osteons and their inner lamella. And finally he will introduce the process of bone remodeling, which is carried out by crews of osteocytes, osteoblasts, and osteoclasts.

Can It Support You? No Bones about It!

(View Complete Item Description)

After completing the associated lesson and its first associated activity, students are familiar with the 20 major bones in the human body knowing their locations and relative densities. When those bones break, lose their densities or are destroyed, we look to biomedical engineers to provide replacements. In this activity, student pairs are challenged to choose materials and create prototypes that could replace specific bones. They follow the steps of the engineering design process, researching, brainstorming, prototyping and testing to find bone replacement solutions. Specifically, they focus on identifying substances that when combined into a creative design might provide the same density (and thus strength and support) as their natural counterparts. After iterations to improve their designs, they present their bone alternative solutions to the rest of the class. They refer to the measured and calculated densities for fabricated human bones calculated in the previous activity, and conduct Internet research to learn the densities of given fabrication materials (or measure/calculate those densities if not found online).

Hearing: How Do Our Ears Work?

(View Complete Item Description)

Students learn about the anatomy of the ear and how the ears work as a sound sensor. Ear anatomy parts and structures are explained in detail, as well as how sound is transmitted mechanically and then electrically through them to the brain. Students use LEGO® robots with sound sensors to measure sound intensities, learning how the NXT brick (computer) converts the intensity of sound measured by the sensor input into a number that transmits to a screen. They build on their experiences from the previous activities and establish a rich understanding of the sound sensor and its relationship to the TaskBot's computer.

Pupil

(View Complete Item Description)

In this activity, learners explore their eye pupils and how they change. Learners use a magnifying glass, mirror, and flashlight to observe how their pupil changes size in response to changes in lighting. Learners also experiment to determine how light shining in one eye affects the size of the pupil in their other eye. This resource guide includes background information about pupils and why they change as well as information related to emotional stimuli, involuntary reflexes, and photography.

Genetics

(View Complete Item Description)

This activity begins with sections that help students to understand basic principles of genetics, including (1) how genotype influences phenotype via the effects of genes on protein structure and function and (2) how genes are transmitted from parents to offspring through the processes of meiosis and fertilization. Then, a coin flip activity models the probabilistic nature of inheritance and Punnett square predictions; this helps students understand why the characteristics of children in many real families deviate from Punnett square predictions. Additional concepts covered include polygenic inheritance, incomplete dominance, and how a new mutation can result in a genetic condition that was not inherited. This activity helps students meet the Next Generation Science Standards.

Genetics

(View Complete Item Description)

This science resource covers a variety of topics; however, the specific URL is on Genetics. It has significant explanations on the basic Principles of Genetics, Co-dominance, Incomplete dominance, and Sex-Linked traits. The units have precise and manageable explanations, and there are numerous links and additional resources to support instructors and students to advance learning. The access to videos and online simulations enhances particular areas, and the diverse assessments support mastery of skills. This is a very purposeful resource on genetics; it is useful to make learning more effective either as an overall instructional method or as an individualized learning supplement.

Medicines by Design

(View Complete Item Description)

Medicines By Design aims to explain how scientists unravel the many different ways medicines work in the body and how this information guides the hunt for drugs of the future. Pharmacology is a broad discipline encompassing every aspect of the study of drugs, including their discovery and development and the testing of their action in the body. Much of the most promising pharmacological research going on at universities across the country is sponsored by the National Institute of General Medical Sciences (NIGMS), a component of the National Institutes of Health (NIH), U.S. Department of Health and Human Services. Working at the crossroads of chemistry, genetics, cell biology, physiology, and engineering, pharmacologists are fighting disease in the laboratory and at the bedside.
