Pregnant women exposed to PAH air pollution increase the risk of obesity in their children. The example of epigenetics, along with others, builds the basis for understanding the process of cell differentiation. Scholars view a video,...

Finding a balance between too much protein and not enough doesn't have to be a guessing game. Young scientists use an interactive lesson to learn how to calculate protein content in cattle feed and how to mix feed to create the ideal...

Students explore the various types of nutritious foods that can be eaten at meal and snack times. they discuss the types of food they eat at mealtimes. Students use Kidspiration to create a web for each mealtime and each snack.

Young chefs follow the set-by-step instructions of a recipe and use their prior knowledge of the body parts of a spider to make edible spider cookies.  After completing a pre-writing graphic organizer they then write a "how to"...

Three activities introduce upper elementary ecologists to photosynthesis and food webs. In the first, an experiment is set up to determine how plants respond to different types of light. In the second, they connect organism cards with...

Junior scientists work in groups to construct electromagnets. They experiment by varying number of wraps around the nail, the diameter of the nail, and the type of metal the nail is made of to see if any of these factors has an...

The first stage in the butterfly's life cycle is the egg. Young entomologists discuss why different butterflies lay different eggs and what their eggs look like. Then they use the handouts to make a replica of one type of butterfly egg...

Students examine the importance of good quality safety gear. In this investigative lesson plan, students will tests various polymers, collect data, and analyze the data to determine which polymer is best for safety helmets. They will...

Students construct a plsmid model with the materials provided and be able to use it to define certain terms and explain other practical applications of genetic engineering. This simulation allows the students to work through the diagram...

Students explore watersheds through the use of a topographic map. They observe topographical maps and discuss their characteristics. In groups, students create a model clay island and make a topographical map of it. Afterward, groups...

In this molecular model worksheet, students use a molecular model kit to construct 13 different molecule models. After constructing the molecules, the students complete 32 short answer questions.

Students create a model of centrifugal compressor wheel following step-by-step instructions. In this technology lesson plan, students use SolidWorks to create curved surfaces. They give practical applications of a centrifugal compressor.

Students study insect camouflage. In this organisms lesson, students design and create their own 3D insect models to blend into a habitat. Students write a paragraph about the camouflage their insect has and explain how their insect is...

Students draw an accurate geologic cross section by using a given data table. They relate the features of the cross section to geologic processes. Students then relate the characteristics of the bedrock to the architecture.

Learners construct models of hydrocarbon molecules using candy and toothpicks. In this hydrocarbons lesson plan, students are given a sheet with the molecular formulas of hydrocarbons. As a group, they construct each molecule using...

Students engage in a lesson in which volcanoes be explored and examined. After watching a video, students create volcanoes out of clay.

Students explain habitats. In this model based lesson plan students create a model to help describe a habitat that is typical of deep-water. Students will describe how organisms such as coral and sponges add to their habitat.

Students assemble a poster of an estuary showing the five communities of animals and plants that inhabit the estuary. They research the concept of an estuary and find photographs or diagrams of various estuaries to identify and see the...

Students record scientific observations in a science journal.  In this season lesson, students make observations about each of the seasons and record in their journals.  Students record organisms response to seasonal changes...

Students simulate the formation of chondrites and asteroids. In this astronomy lesson plan, students demonstrate accretion using balloons and static electricity. They compare and contrast their models to the actual process of chondrites...

Students investigate the strength of different adhesives. In this physical science lesson plan, students compare the force needed to peel adhesive tapes from a surface. They analyze collected data and make a generalization.

Sixth graders simulate primary and secondary waves. For this earthquakes waves lesson, 6th graders experiment using a slinky to gain understanding of how waves are created during an earthquake. Students record observations in drawings....

First graders study the animals in the Maya Forest Reserve. For this conservation lesson, 1st graders create a graph to compare the environment of animals to their own. They design a 3D model of these two environments.

Students identify the locations on a map of the airplane crashes discussed in this instructional activity. After watching a video, they discuss the importance of an investigation after a plane crash. They use the same information as...
