Students randomly select jelly beans (or other candy) that represent genes for several human traits such as tongue-rolling ability and eye color. Then, working in pairs (preferably of mixed gender), students randomly choose new pairs of jelly beans from those corresponding to their own genotypes. The new pairs are placed on toothpicks to represent the chromosomes of the couple's offspring. Finally, students compare genotypes and phenotypes of parents and offspring for all the "couples" in the class. In particular, they look to see if there are cases where parents and offspring share the exact same genotype and/or phenotype, and consider how the results would differ if they repeated the simulation using more than four traits.

The human brain is in many ways a fantastic and enigmatic part of the body, and only within the past few decades have scientists begun to understand its many nooks and crannies. When the brain is beset with any number of neurological conditions, it changes in a myriad of ways. This website, provided by the Alzheimer's Association, provides an interactive tour of the brain of a person with Alzheimer's disease. The tour contains sixteen interactive slides, and each slide contains informative text that provides background material. The first seven slides contain a bit of background information about the brain, such as what the brain is composed of and how it functions.

This video lesson is on the details of cancer cell growth. How do cancer cells grow? How does chemotherapy fight cancer (and cause negative side effects)? The answers lie in cell division. George Zaidan explains how rapid cell division is cancer’s "strength" -- and also its weakness.

This 13-minute video lesson looks at the science of taxonomy and where humans fit into the tree of life. [Biology playlist: Lesson 62 of 71].
Material Type: Lecture
This lesson teaches the engineering method for testing wherein one variable is changed while the others are held constant. Students compare the performance of a single paper airplane design while changing the shape, size and position of flaps on the airplane. Students also learn about control surfaces on the tail and wings of an airplane.

From something as small and complex as a chromosome to something as seemingly simple as the weather, sex determination systems vary significantly across the animal kingdom. Biologist and teacher Aaron Reedy shows us the amazing differences between species when it comes to determination of gender.

This case study follows a family's dilemma about how to save money on gasoline. Should they keep their SUV and trade in their Corolla for a hybrid sedan? Going from 28 (Corolla) to 48 (Hybrid) miles per gallon (MPG) should really save money on gas. That's a change of 20 MPG! Or, should they keep their Corolla and trade in their SUV for a minivan? The SUV gets about 13 MPG while the Minivan gets 17 MPG. Students learn how to analyze fuel efficiency in terms of "gallons per miles" driven instead of miles per gallon, and gain graphing and data analysis skills. An extension activity also relates fuel efficiency to greenhouse gas emissions. The case was developed for use in a high school general science course. It could be adapted for use in introductory physics, chemistry, algebra, or environmental science courses at the high school or college level.

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.

In this online interactive, learners investigate how Earth's three-dimensional, physical environment is represented on a two-dimensional topographic map. Learners explore the essential parts of a map including legend, scale, and slope indicators. Map reading skills are then tested by learners choosing the best trail to take in different scenarios.

In The Botany of Desire, Michael Pollan explores risks inherent in one of the most widespread practices in modern agriculture. It's called monoculture, and it refers to cultivation of single or very similar varieties of a food crop on large acreages. In many cases, the variety is one that dominates the marketplace, like the Russet Burbank potato, whose shape makes it a favorite for cutting French fries, or one of the few apple varieties commonly seen in supermarkets. Monoculture may offer economic advantages, but Pollan argues that it brings serious environmental risks.

Adam Savage walks through two spectacular examples of profound scientific discoveries that came from simple, creative methods anyone could have followed -- Eratosthenes' calculation of the Earth's circumference around 200 BC and Hippolyte Fizeau's measurement of the speed of light in 1849. A quiz, thought provoking question, and links for further study are provided to create a lesson around the 7-minute video. Educators may use the platform to easily "Flip" or create their own lesson for use with their students of any age or level.
