Intro to History of Science: Crash Course History of Science #1
How, and where, did the scientific process as we know it begin? Journey back through time with the introductory video from Crash Course's History of Science series. The resource highlights what people do and don't know about the world,...

Thermoregulation
Hey, crank up the thermostat, my computer froze again! In a thermoregulation video, learners see how organisms either maintain their body temperatures or do not. The instructor explains the difference between conduction, convection,...
Bozeman Science
Homeostatic Loops
When someone is hot and their face is red, it is due to capillaries bringing blood closer to the surface of our skin so more heat can be lost. In the video, learners explore homeostasis and its role in the human body. Four homeostatic...

Cell Communication
Humans have taken communication to every corner of the Earth, yet our bodies, at the cellular level, have communicated without technology for millions of years. Learners view the variety of ways cells can communicate, whether right...

Reproductive System
The human reproductive system contains the largest (egg) and smallest (sperm) cells in the human body. It's time for scholars to review the differences between asexual and sexual reproduction. The instructor reminds them how meiosis...

Digestive System
The human body produces about 1.7 liters of saliva a day to aid in digestion. Here is a video that explores the digestive system, highlighting the difference between mechanical and chemical digestion. Scholars then see each organ of the...
Bozeman Science
Muscular System
To take one step, the body uses about 200 muscles. In the video, learners see the difference between the three types of muscles found in the human body—skeletal/striated, smooth, and cardiac. The instructor then explains, in detail, how...
Bozeman Science
Homeostasis Hugs
Penguins, seals, and whales have countercurrent heat exchangers to limit blood flow in certain areas of their body, limiting their rate of heat loss to their environment. In this homeostasis video, the instructor explains that...
Bozeman Science
Anatomy and Physiology Introduction
Muscle tissue is three times more efficient at burning calories than fat. Here is a video that explores how form fits function, introducing anatomy and physiology. The instructor then explores homeostasis, hierarchy associated with...
Bozeman Science
Coupled Relations
Energy from the sun travels millions of miles, and actually helps you move your thumb. Observe how reactions work together to release and consume energy, such as the power of a river grinding grains, which allows processes to occur....
Bozeman Science
Nervous System
The average adult human brain contains 100 billion neurons. In the video, scholars learn about brain lateralization and how different portions of our brain do different things. Learners then explore neurons, learning their parts and how...
Bozeman Science
Sensory System
Humans can sense about 10,000 different odors. Young scientists explore how humans interpret the world around them using their senses. The instructor reminds learners of action potentials and the nervous system and then focuses on three...
Bozeman Science
Endocrine System
The pineal gland in the endocrine system secretes melatonin which helps humans sleep. In this human body video, scholars explore the major parts of the endocrine system. The instructor explains the roles of hormones, glands, and cells...
Bozeman Science
Fight or Flight Response
Harboring resentment against others is just as real to your body as a dangerous situation and can invoke a fight or flight response. The video explores the fight or flight response in humans. Viewers see what is happening inside the...
Bozeman Science
Skeletal System
Adults' bodies are made of 206 bones, whereas babies have about 300 different bones or areas of cartilage. Pupils explore the difference between exo- and endo- skeletons in a video about the skeletal system. They then see how bones are...
Bozeman Science
Interstitial Fluid
Humans have more interstitial fluid than blood, but what is interstitial fluid? The video allows learners to understand interstitial fluid by seeing it in a photo, learning its definition, showing where it comes from thanks to...
Bozeman Science
Signal Transmission and Gene Expression
Budding scientists learn about signal transmission, exploring intercellular and intracellular chemical movements. The instructor shows how epinephrine signals other chemicals in the body and can cause our DNA to express different...
