Heredity: Your Connection To The Past

What better way to make predictions about future weather and climate patterns than with actual climate data from the past? Young climatologists analyze data from 400,000 to 10,000 years ago to determine if climate has changed over time....

Are you the predator or the prey? Student groups participate in an activity to demonstrate the process of natural selection in a contained environment. After scholars complete the activity and questions, they apply their knowledge to a...

Learners compare fossilized specimens to contemporary specimens. They use a computer and a Proscope Digital USB Microscope to collect and compare images of ferns, sand dollars and sow bugs to those of similar fossilized samples.

Scientists use ice core samples to obtain temperatures of the earth from 400,000 years ago! The third of five lessons instructs pupils to interpret historical climate data to see changes over time. In part I, participants interpret...

Detailing the structures and functions of flowering plants, this slide show will help your students understand the processes and the conditions that allow pollination and fertilization. Labelled diagrams help introduce the reproductive...

What a fun way to explore Mendelian Genetics! Using a computer connected to the Internet, beginning biologists construct and use Punnett squares of monohybrid crosses to explain how genetic traits are passed to offspring. Other websites...

Students come to understand that in sexually reproducing organisms, such as humans, typically half of the genes come from each parent. Students examine a fictional pedigree and determine which gene is responsible for a given trait. The...

Students plant seeds in order to investigate and explore the questions: "How do seed companies develop varieties of plants?" and "What is the ideal plant?" Students will study related vocabulary and sketch seeds as they emerge. Students...

Learners practice looking at their genetics to inquire about their past. In groups, they determine their recessive and dominant genes and plot their height on a graph. They compare and contrast the processes of meiosis and mitosis. ...

Did you know that the biggest organ in the human body isn't the brain, the liver, or even the lungs? It's the skin. Follow along with this short video as it explores the structure of human skin and its amazing ability to regenerate itself.
