All of us have felt sick at some point in our lives. Many times, we find ourselves asking, "What is the quickest way that I can start to feel better?" During this two-lesson unit, students study that question and determine which form of medicine delivery (pill, liquid, injection/shot) offers the fastest relief. This challenge question serves as a real-world context for learning all about flow rates. Students study how long various prescription methods take to introduce chemicals into our blood streams, as well as use flow rate to determine how increasing a person's heart rate can theoretically make medicines work more quickly. Students are introduced to engineering devices that simulate what occurs during the distribution of antibiotic cells in the body.

This video on phenology of plants and bees discusses the MODIS satellite finding that springtime greening is happening one half-day earlier each year and correlates this to bee pollination field studies.

Working individually or in groups, students explore the concept of stress (compression) through physical experience and math. They discover why it hurts more to poke themselves with mechanical pencil lead than with an eraser. Then they prove why this is so by using the basic equation for stress and applying the concepts to real engineering problems.

This video describes the role of the brain in regulating body temperature and how sometimes fever is employed to fight off infection.

This video segment from the teacher video series Learning That Works uses a case study to highlight the effectiveness of a project-based, real-world approach to teaching science.

In this activity, the students will investigate a variety of plants and animals common to the Amazon through research. They will determine the plant or animal characteristics that make them edible or useful for the trip and learn to categorize them by comparing similarities and/or differences.

This Evolution video segment depicts the landmark hominid fossil finds by Don Johanson and his team in Ethiopia.

Using this lesson plan students will be more aware of how plants and animals adapt to wildland fire. They will: Discuss the adaptive strategies of plants and animals to survive fire. Observe plants and animals in your local area. Design a plant or animal that is adapted for fire survival.

This activity is takes place in nature and in the classroom. Students are gathering different types of leaves and naming characteristics of each then sorting them by those characteristics. Students then make a picture with leaves and writes 2-3 sentences about their picture using the characteristic words.

This is a unit for K-2 students on fish habitats. The last day is a field trip to a local lake.

In this video segment from Evolution: "Great Transformations," paleontologist Jenny Clack explains that vertebrates evolved fingers before they invaded land.

This guided inquiry activity is designed to help students understand that people get all of their knowledge from their senses, and that is why our senses are so important.

This video segment from NatureScene features the area of the Congaree Swamp where the high ground and the flood plain meet. Learn how a few feet of difference in elevation on a floodplain can yield drastic changes in what youŰ__Ű__ŒŒÇll find living there.

In this lesson designed to enhance literacy skills, students learn about the unique environment of southern Florida's Everglades and gain insights into the interrelatedness of living things, nonliving things, and climate.

Students will learn about the ways garden organisms depend on each other for survival and create "human" food chains to show how energy is transferred from the sun to living things.

Students will observe organisms in their ecosystem and describe the flow of energy in food webs

This article provides science content knowledge about forces that shape the Earth's surface: erosion by wind, water, and ice, volcanoes, earthquakes, and plate tectonics and how these forces affect Earth's polar regions.

This video segment from NOVA: "The Killer's Trail" investigates the potential for DNA evidence to solve murder cases, even those from the distant past.
