A lesson plan for Grade 7 English Language Development and Science. Students develop their knowledge of the circulatory system by studying the structure and function of the heart and its vessels.

Find out how angles and symmetry come into play in the game of pool in this video adapted from Annenberg Learner’s Learning Math: Measurement.

This video segment from NOVA: "Animal Imposters" shows the lightning-fast strike of the anglerfish.

Meiosis is important in assuring genetic diversity in sexual reproduction. Use this interactive animation to follow Meiosis I (reduction division) and Meiosis II in a continuous sequence or stop at any stage and review critical events.

This animation demonstrates the stages of mitosis in an animal cell. Use the control buttons in the upper left to run the complete animation. Click on any intermediate stage (for example, Anaphase), and see a representative still frame.

Try your hand at assembling the following animal cell jigsaw puzzle created with an image from CELLS alive! This puzzle is 32 pieces and generally takes a few minutes to solve. Have fun!

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.

Students will explore the outdoor classroom in pairs looking for evidence of animal life and imagining what types of animals might live in, and survive in, the outdoor classroom area.

Students build a 9 M X 9 M model of an animal or plant cell with cell organelles inside it and give cell tours to Life Science students. May be done as two large groups, or a whole class project.

Farming ants might sound like a crazy thing to do unless you might like to eat chocolate covered ants. It turns out we can learn a lot from ants and the best way is to build your own ant farm.

This article describes a discovery of moss and ostracod fossils that led to a better understanding of Antarctica's climate history.

In this video, Jonathan treks all the way to Antarctica to investigate life south of the polar circle. Along the way he dives in the majestic kelp forests of Patagonia, where crabs rule the sea floor. Once he arrives in Antarctica, his adventures continue. He swims with penguins, dives under an iceberg, meets a massive jellyfish 3 feet wide, and has an incredible encounter with a Leopard seal, the apex predator of Antarctica. Part 1 finds Jonathan diving in Ushuaia, Patagonia in Argentina before boarding the ship to Antarctica, then he finally gets to Antarctica and meets some penguins! This program won a New England Emmy Award! Please see the accompanying lesson plan for educational objectives, discussion points and classroom activities.

Along the way he dives in the majestic kelp forests of Patagonia, where crabs rule the sea floor. Once he arrives in Antarctica, his adventures continue. He swims with penguins, dives under an iceberg, meets a massive jellyfish 3 feet across, and has an incredible encounter with a Leopard seal, the apex predator of Antarctica. Part 2 finds Jonathan continuing his exploration of Antarctica including an encounter with a Leopard seal. This program won a New England Emmy Award!

In this demonstration, amaze learners by performing simple tricks using mirrors. These tricks take advantage of how a mirror can reflect your right side so it appears to be your left side. To make the effect more dramatic, cover the mirror with a cloth, climb onto the table, straddle the mirror, and then drop the cloth as you appear to "take off." This resource contains information about how this trick was applied during the making of the movie "Star Wars."

This lab activity will not only draw on students' real life experiences but will also draw on student's previous lab experiences in proper laboratory techniques and data analysis performed in previous activities. The lab will incorporate the use of scientific inquiry methods and strategies while students develop reasonable answers to the questions asked.

This is a great site to learn about apoptosis. It includes pictures, information, and links to other great sites on apoptosis. There is also a video that is available for download.

In this video Jonathan visits the New England Aquarium as a volunteer aquarist for a day to learn what it takes to care for thousands of fish in dozens of exhibits, up to the massive 200,000 gallon Giant Ocean Tank (GOT). What he finds is an eye opener‰ŰÓit‰ŰŞs not all fun and games. Maintaining an aquarium is serious work. But it does have its benefits, as Jonathan discovers while diving in the GOT and feeding the sharks. This segment won a New England Emmy Award! Please see the accompanying study guide for educational objectives and discussion points.

Students create four-legged walking robots and measure how far they travel across different types of surfaces. They design and create "shoes" to add to the robots' feet and observe the effect of their modifications on the net distance traveled across the various surface types. This activity illustrates how the specialized locomotive features of different species help them to survive or thrive in their habitat environments. The activity is best as an enrichment tool that follows a lesson that introduces the concept of biological adaptation to students.

The purpose of this resource is to observe when selected bird species first arrive at your study site, and to count the numbers until few or none of these birds are seen. Students select a common and easily identifiable bird species in their region and observe when the bird species first arrives. Students use binoculars or telescopes to scan a study site and count how many they see. They continue to observe every other day until few or none of the selected species can be seen.
