Resource provides a biography of the scientist Andre Marie Ampere.
The homeobox genes that define the basic body plan of mice and fruit flies are illustrated in this graphic from The Human Evolution Coloring Book by Adrienne Zihlman. The accompanying article describes how these genes act as "molecular architects" in all animal species.
It takes a thick skin to withstand the hardships that life has to offer. This collection of images shows a variety of animals, each with a slightly different type of protective covering.
Resource pages of 149 animals from the Cleveland Metroparks Zoo. Each page contains animal details, habitats and known living areas, conservation status and threats, diet, photographs and videos, external resources, and downloadable fact sheets.
This collection of images of six different creatures, including insects and carnivorous vertebrates, illustrates the wide range of mouth types that exist within the animal kingdom. It also discusses the environment and its impact on the evolution.
Join teachers and students all over the country in observing the migratory patterns of birds and butterflies and the growth changes of plants as the climate changes. "Journey North" offers a wealth of resources to use as you investigate the causes and effects of seasonal change: maps, shared data from all over the country, migratory news, FAQs from experts, videos, and slide shows. You'll also learn how to track the coming of spring with your very own tulip study.
This lesson plan will help students explore adaptation, especially as it relates to migration. Students will come to realize that adaptations can be behavioral as well as physical. Students are assigned a particular animal to investigate and they consider all the adaptations that enable it to migrate.
Impressive animated slideshow presentation on the sun's daily cycle and how the sunlight changes hour by hour over the course of a day. Includes a teacher guide with lesson plan ideas and activities.
This student observation guide walks learners through setting up an investigation of the seasons and their causes. Students can report their actual data right there on the page.
This is an appropriate resource for investigating the impact seasonal change has on organisms. Have your students track the changes that come with spring by journaling. The online table addresses physical changes in the environment (temperature, etc.) as well as changes in plants and animals.
This video segment [3:33] adapted from NOVA explains why ice sheets move. To find out how fast they move, scientists carve a tunnel through a glacier.
What would happen if a portion of the Antarctic Ice Sheet were to melt? This video segment [3:19] adapted from NOVA uses animations to show the effect of a 6-meter sea-level rise on coastal cities across the world.
Discover the stars with Peter. At his mom's research center, help Peter learn constellations and learn about characteristics of stars.
Paul is a researcher on Antarctica. The topic of his research is sounds. Identify which objects make sounds, and learn to recognize different sounds.
James lives on Antarctica and loves the unique sounds he hears there. He is curious to know how it is possible that we hear sounds. Join him to help figure this out.
This video segment adapted from NOVA uses microwave images to reveal how sea ice doubles the size of Antarctica each winter. Rare footage shows how sea ice crushed the famous ship Endurance in 1914. [2:34]
Join Sam on his journey to the bottom of the sea. Explore beautiful animals living in the sea, and learn about the importance of a well-balanced habitat.
Learn about the antiparallel structure of DNA strands which can by 5 feet to 3 feet directionality. [9:57]
