Heredity Mix n Match

(View Complete Item Description)

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.

Inside the Brain: An Interactive Tour

(View Complete Item Description)

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 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.

The Botany of Desire

(View Complete Item Description)

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.

How Simple Ideas Lead to Scientific Discoveries

(View Complete Item Description)

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.

California Foundation for Agriculture in the Classroom Lesson Plans

(View Complete Item Description)

This database of lessons is provided to support agriculture education in California classrooms. Over the last century, children have become further removed from the land that feeds and clothes us. And yet, Agriculture is the very basis of civilization—the food we eat, the clothing we wear, the material of our homes and many of our traditions and values…all coming from agriculture and collectively setting the pace for a nation's standard of living. The California Foundation for Agriculture in the Classroom works with K–12 teachers, and students to enhance education using agricultural examples.
