This animation allows students to view the processes of photosynthesis and respiration. In particular, it tackles the common misconception among students that respiration in plants does not take place at the same time as photosynthesis. Teachers' notes are provided.
Students will create an animation to represent one of the many feedback loops that influences climate change. To create their animation, students will use clay, cut paper, whiteboard or other materials commonly found in the classroom. They will make a storyboard, plan a narration, rehearse their animation and then film their animation with stop-motion photography.
Part of NCSSM CORE collection: This animation demonstrates the ratio of the combining volumes of hydrogen and oxygen gas to form water.
This 11-slide PowerPoint presentation presents a short succession of schematic diagrams illustrating the structural evolution of anorthosites. The slides discuss the relative abundance of rare earth elements, describe six types of anorthosite occurrence, and contain pictures showing anorthositic texture. This resource is part of the Teaching Petrology collection. http://serc.carleton.edu/NAGTWorkshops/petrology03/index.html
This informational text explains that while both the Arctic and Antarctica are cold, Antarctica is much colder and drier - a polar desert. The text is written at a grade four through grade five reading level. This is a PDF containing the informational text and a glossary.
In this activity, students investigate how increasing the surface area of a chemical increases its reaction rate. Students will compare the reaction rates when a whole antacid tablet and a crushed tablet are added to separate beakers of water.
This activity, which centers on Antarctica, challenges students to research and create the answers and questions for a game of classroom Jeopardy. The printable six-page handout includes a series of inquiry-based questions to get students thinking about Antarctica and guidelines for conducting additional research, illustrated activity directions and a worksheet that helps students craft their Jeopardy-style answers and questions.
This article describes a discovery of moss and ostracod fossils that led to a better understanding of Antarctica's climate history.
This article includes links to expository text for students in grades K-1, 2-3, and 4-5 about the climate differences between the Arctic and Antarctica.
This informational text explains that while both the Arctic and Antarctica are cold, Antarctica is much colder and drier - a polar desert. The text is written at a grade two through grade three reading level. This version is a full-color PDF that can be printed, cut and folded to form a book. Each book contains color photographs and illustrations.
This classroom activity introduces students to Antarctica's organisms, landscapes, and seascapes. After examining the images in the photo gallery, students work in small groups to discuss their conclusions about the living conditions on this continent. The printable three-page handout includes a series of questions to help students structure their thoughts while viewing the gallery images and a group worksheet that guides students through a discussion of their evolving hypotheses and conclusions.
Students will explore how human population growth, air pollution, agriculture, mining, water use, and other human activities have impacted the environment and the mark they will leave in the fossil record.
In this lesson, students learn about the newest class of antibiotics as well as the current classes of antibiotics and the biological processes behind antibiotic resistance. In a culminating activity, students will model how resistant pathogens alter population dynamics using M&Ms and marshmallows.
Students view a video about antibiotics and learn how they work to kill bacteria. In an associated activity, students will demonstrate how antibiotics work and how antibiotic-resistant bacteria can survive a medication's actions.
Finding and eradicating invasive plants is a tough job that requires constant vigilance. County-scale maps that show where invasive plants are and where they have the potential to spread in the future are helping on-the-ground efforts to build the resilience of natural vegetation.
The purpose of this video lesson is to expand the student's knowledge about enzymes by introducing the antioxidant enzymes that are intimately involved in the prevention of cellular damage and eventual slowing of the aging process and prevention of several diseases. Students will learn that natural antioxidant enzymes are manufactured in the body and provide an important defense against free radicals. The topic of free radical action is introduced, covering how they are constantly generated in living cells both by "accidents of chemistry" and also by specific metabolic processes.
In this lesson, students will learn that ice formations on land will cause a rise in sea level when they melt, whereas ice formations on water will not cause a rise in sea level when they melt. They will also learn that ice is less dense than water, that ice displaces water equal to the mass of the ice, and they will practice some of the steps involved in a science investigation.
NASA presents this gallery of images from the Apollo 11 mission to the moon in 1969.
Students learn about the locations and geology of the six Apollo landing sites.
