Mega Virus
By: M. Gail Jones, Amy R. Taylor, and Michael R. Falvo
Grade Level: High School, Middle School
The study of science at the extremes of size often involves creating and testing models of science phenomena. Scientists and engineers often build models at different sizes and scales. These models can be physical, such as a Styrofoam ball model of the solar system; virtual models such as animations; or mathematical models such as are used in predicting weather. In this investigation, students create different-sized models of the common cold virus...  [view full summary]

These models can be physical, such as a Styrofoam ball model of the solar system; virtual models such as animations; or mathematical models such as are used in predicting weather. In this investigation, students create different-sized models of the common cold virus (adenovirus) and determine the scaling ratios for each model.

Your World or Mine? Different Perspectives
By: M. Gail Jones, Amy R. Taylor, and Michael R. Falvo
Grade Level: High School, Middle School
Is the glass half-empty or half-full? That depends on your perspective. Differences in vantage point or prior knowledge can lead to different interpretations or conclusions. Scientists also have various perspectives on new discoveries or the results of experiments. In this activity, students will gain awareness of differing perspectives and consider how scientists must sometimes work together to navigate challenge concepts.

Observing Nature
By: Judy Scotchmoor (Revised New Edition), Robert Stebbins, David Ipsen, Gretchen L. Gillfillan, and Judy Diamond (Revised New Edition)
Grade Level: Elementary School, Middle School
In this activity, students will be asked to review their experiments from the previous chapters. Throughout this book, the students have studied animal coloration through the use of models, rather than by investigating living animals. This activity gives students the opportunity to use the knowledge they have gained to design an investigation in a real life setting.

What Is Scale?
By: M. Gail Jones, Amy R. Taylor, and Michael R. Falvo
Grade Level: Elementary School, Middle School
Scale is one of the big ideas that cross the science domains. Whether one is talking about the weight of a blue whale, the size of a galaxy or a molecule, or the age of a mountain range, scale is an essential tool in understanding the universe in a scientific way. But what exactly is scale, and why is it important? In this investigation, students explore size and scale by examining the wide range of scales that are investigated in science.

Zoom Zoom: Magnification
By: M. Gail Jones, Amy R. Taylor, and Michael R. Falvo
Grade Level: High School, Middle School
As science extends into the very large and the very small ends of the scale, the images of objects and materials lose recognizable contexts and can be very complex. New advances in microscopes and telescopes allow us to zoom in on very tiny and very distant objects and see amazing new worlds. This investigation involves students in thinking about the changes in scale that take place as we zoom in on very small and very large objects.

That’s Hot! The Effect of Size on Rate of Heat Loss
By: M. Gail Jones, Amy R. Taylor, and Michael R. Falvo
Grade Level: High School, Middle School
Through the use of common household items such as aluminum pans and thermometers, students will investigate how the size and shape of an object affect the rate of heat loss from the object to the environment. This lesson is relevant to biology, as it relates to the size and shape of animals, their metabolism, and their ability to live in very cold or hot environments. A rate of heat loss that is too fast or too slow may affect the survival of an organism....  [view full summary]

This lesson is relevant to biology, as it relates to the size and shape of animals, their metabolism, and their ability to live in very cold or hot environments. A rate of heat loss that is too fast or too slow may affect the survival of an organism. By modeling different shapes and sizes of organisms using containers of various sizes, students explore how these variables affect the rate of heat loss.

Eye in the Sky: An Introduction to GIS & Scale
By: M. Gail Jones, Amy R. Taylor, and Michael R. Falvo
Grade Level: High School, Middle School
New computer technologies allow us to examine scientific data at a variety of different scales from global to local. In this investigation students use Geographic Information Systems (GIS) as a tool to investigate different questions related to the environment. Questions on subjects ranging from changes in tree canopy to Africanized bee habitats or climate changes can be investigated with GIS.

Drops to the Ocean: A GIS Study of River Basins
By: M. Gail Jones, Amy R. Taylor, and Michael R. Falvo
Grade Level: High School, Middle School
Water is a critical element of life. It plays a crucial role at many scales from singles cells to huge river systems. In this investigation, students explore local, regional, and global river basins using GIS as a tool. The study begins with an examination of river basins on paper maps, followed by observations at different levels of detail revealed with interactive GIS maps. These exercises allow students to explore water systems across a range of...  [view full summary]

Concealing Behavior
By: Robert Stebbins, David Ipsen, Gretchen L. Gillfillan, Judy Diamond (Revised New Edition), and Judy Scotchmoor (Revised New Edition)
Grade Level: Elementary School, Middle School
A previous activity suggested the importance of behavior to an animal with coincident coloration. If the stripe-legged frog fails to fold its legs, the disruptive markings on them lose much of their effectiveness. If, when at rest, a moth with coincident wing markings on them lose much of their effectiveness. If, when at rest, a moth with coincident wing markings leaves its wings spread too widely after alighting, the coincident pattern that normally...  [view full summary]
A previous activity suggested the importance of behavior to an animal with coincident coloration. If the stripe-legged frog fails to fold its legs, the disruptive markings on them lose much of their effectiveness. If, when at rest, a moth with coincident wing markings on them lose much of their effectiveness. If, when at rest, a moth with coincident wing markings leaves its wings spread too widely after alighting, the coincident pattern that normally cuts across them is broken into pieces. This activity considers further aspects of behavior that may influence the effectiveness of their concealing coloration. In the second activity, further attention is paid to the influence of behavior on concealment as students put to test much of their recently acquired knowledge by playing the Lizard Game.

Evolution and the Functions of Color
By: Robert Stebbins, David Ipsen, Gretchen L. Gillfillan, Judy Diamond (Revised New Edition), and Judy Scotchmoor (Revised New Edition)
Grade Level: Elementary School, Middle School
The purpose of the first activity is to stimulate students’ interest in the coloration of animals. While students may already be aware that the white coat of the polar bear provides some measure of concealment in the snowy surroundings of the Arctic, or that the green color of certain caterpillars may be helpful to them in their leafy habitat, they have probably not stopped to think that the coloration of many animals serves a useful function. Therefore,...  [view full summary]

While students may already be aware that the white coat of the polar bear provides some measure of concealment in the snowy surroundings of the Arctic, or that the green color of certain caterpillars may be helpful to them in their leafy habitat, they have probably not stopped to think that the coloration of many animals serves a useful function. Therefore, the primary purpose of this activity is to suggest that any question about animal coloration may have an answer, perhaps even an answer that students themselves can discover.
