B. Processes in a cell can be classified broadly as growth, maintenance, reproduction, and homeostasis.
C. Life can be organized in a functional and structural hierarchy ranging from cells to the biosphere.
D. Most multicellular organisms are composed of organ systems whose structures reflect their particular function.

STEM Lessons - Model Eliciting Activity
In this Model-Eliciting Activity (MEA), students will learn about the relationship between fast food choices and heart health. It should give students dietary choices to assist in the prevention of high blood pressure and heart disease.
Model Eliciting Activities, MEAs, are open-ended, interdisciplinary problem-solving activities that are meant to reveal students’ thinking about the concepts embedded in realistic situations. MEAs resemble engineering problems and encourage students to create solutions in the form of mathematical and scientific models. Students work in teams to apply their knowledge of science and mathematics to solve an open-ended problem while considering constraints and tradeoffs. Students integrate their ELA skills into MEAs as they are asked to clearly document their thought processes. MEAs follow a problem-based, student-centered approach to learning, where students are encouraged to grapple with the problem while the teacher acts as a facilitator.

This Khan Academy video explains the major vessels involved in the flow of blood and follows the steps that blood takes as it travels through the heart.
Type: Tutorial
This tutorial will help you to understand how all of the components of the heart are able to work together without direct control from the central nervous system. This video shows that for proper function of the heartbeat, it is necessary that all of the muscle fibers in a region contract in unison.

Blood pressure is determined by the force of the blood acting on the walls of the blood vessels. Two factors determine the size of this force. One is the volume of blood being pumped through the vessel. The other is the size of the vessels. Changes in blood pressure can be caused by either a change in the amount of blood being pumped or by a change in the size of the blood vessels. Feedback mechanisms, described in this animation, will alter heart rate and blood vessel dilation to maintain blood pressure at appropriate levels.

This tutorial will help students to understand how concentrations of gases in the blood change during breathing. This animation shows high carbon dioxide concentrations and low oxygen concentrations indicating that gas exchage is occurring at a slower than ideal rate. Because of this, heart rate increases or decreases to compensate the exchange of gas.

This TED ED original lesson takes a closer look at how the heart pumps blood. For most of history, scientists weren't quite sure why our hearts were beating or even what purpose they served. Eventually, we realized that these thumping organs serve the vital task of pumping clean blood throughout the body. But how? Edmond Hui investigates how it all works by taking a closer look at the heart's highly efficient ventricle system.

This video presentation will help to understand the regeneration process in a zebrafish. When the zebrafish heart is damaged, the wound site is rapidly sealed with a fibrin clot that stems bleeding within seconds. Following clot formation, the tissue that surrounds the heart muscle, the epicardium, gradually covers the fibrin clot via migration and cell division. Over the next few months, new cardiac muscle is produced and replaces the clot.

This educational game is about blood types, blood typing, and blood transfusions. Your challenge is to save patients in urgent need of blood transfusions. Your job is to decide what blood type these patients belong to in order to administer safe blood transfusions. At the end you will be evaluated: if you make no mistakes at all you will get all five blood drops.
