Sixth graders design experiments to compare the amount of bacteria in river water to the amount in purified tap water. They explore how water purification removes bacteria and pollution from the water. Students examine the steps of the...

Students are focused on the big question: What makes a population grow and how could that growth stop? They use these concepts to help answer the big question: carry capacity, density dependent v. density, independent factors, predation...

Young scholars are able to give examples of local and global sources of pollution. They explain why certain forms of pollution are detrimental to the environment. Students a create a poster promoting Earth Day's message of...

Students explore the effects of different density-dependent and density-independent factors on population growth. They explore how the interactions of organisms can affect population growth. Students explore the pattern of population...

In this atomic weight and ions worksheet, students answer questions about isotopes of atoms and how it relates to atomic weight. They also write out oxidation or reduction reactions for given atoms undergoing loss or gain of electrons.

Although the article that launches this lesson is about the history of the Periodic Table, the objective is reading comprehension. Using the eight-page informational text, learners answer five comprehension questions and craft one essay....

In this nuclear chemistry worksheet, students define radioactivity and the types of nuclear reactions. They label nuclear reactions with one of five types of reactions including fusion, fission, induced, natural decay or electron capture.

For this solutions, suspensions and colloids worksheet, students use diagrams to show how particles are different in each of these mixtures. They also distinguish between characteristics of each of these types of mixtures and categorize...

In this alkanes worksheet, students complete a table with the chemical formula, the structural formula and the condensed formula of various alkanes given different numbers of carbon atoms. They answer three questions about valence...

Fourth graders investigate the significance of natural resources and the habitats of butterflies. They create a list of their own favorite foods, then watch a video about habitats. Students identify things in the video that animals and...

A large data table is given to your elementary earth scientists in which they record observations that they make while viewing pictures of Alaskan glaciers. They compare and contrast recent photos with older photos. Hold a discussion...

Another A+ lesson on the impact of climate change comes to you from the National Earth Science Teachers Association. In this installment, learners model the stratification of water in lakes due to temperature differences. The lab also...

The fascinating video "Changing Planet: Fresh Water in the Arctic," introduces your oceanographers to the world's gyres. They learn that melting sea ice is making the gyres larger, and that the changes could, in turn, contribute even...

Expectant earth scientists examine the bottom side of a leaf and learn the role of the stomata. They consider the gas exchange that occurs through these structures and relate how the climate is changing to its impact on food crops. This...

A video and laboratory investigation are highlights to this lesson on acidification of ocean water due to increased atmospheric carbon dioxide. Using bromothymol blue (BTB) as an indicator, pupils analyze the amount of carbon dioxide...

Resource links to a video, satellite images, data, and photographs of glaciers provide emerging earth scientists the opportunity to examine how the ice has been retreating over the years. A data table is included for pupils to record...

Show the six-minute video, "Changing Planet: Fading Corals," and then demonstrate how calcium carbonate forms a precipitate in the presence of carbon dioxide. Separate your scientists into small groups to gather information about coral...

Here is a different approach: emerging epidemiologists first go home to interview family on the topic of infectious disease. Then they come to class and view a video and PowerPoint that explore how climate change may increase the...

Links to two different versions of this mapping activity are available. In "The Small Version," youngsters design a town, keeping the water supply in mind. In "The Large Version," they also design a town, but they consider services and...

Where does all of the carbon dioxide come from that is supposedly leading to climate change? Earth science pupils test animal, plant, and fossil fuels as sources in this investigation. Using an indicator, BTB, they are able to detect the...

A website links you to several water cycle worksheets geared toward an upper elementary or middle school level. Diagrams, word search, crossword, and fill-in-the-blank worksheets are available. As an added bonus, there are links to...

Students practice using the tool of remote telescopes in order to make observations in space. The instructional activity includes the best times of year to make observations. They use the internet to obtain information and to initiate...

Students identify how technology aids scientists in their research. Through discussion, they explain the various ways scientists use Aerogel to aid in their collection of high-speed particles. Through experimentation, students create...

Students investigate the concept of the constellations using many different resources to find information. Then students use the information in order to construct models of the constellations that show the magnitude of their size and...
