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]

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.

Sweet! Exploring Surface Area of Sugar Molecules
By: M. Gail Jones, Amy R. Taylor, and Michael R. Falvo
Grade Level: High School, Middle School
Two forces that are very familiar to us in our daily lives are gravity and adhesion. The force of gravity on an object, which we commonly refer to as the object’s weight, is proportional to the volume of the object. Adhesion or stickiness, on the other hand, is a surface effect. As objects become smaller, the surface-to-volume ratio increases, changing the relative strengths of these two common forces. At the very small scales, such as the micro-...  [view full summary]
Two forces that are very familiar to us in our daily lives are gravity and adhesion. The force of gravity on an object, which we commonly refer to as the object’s weight, is proportional to the volume of the object. Adhesion or stickiness, on the other hand, is a surface effect. As objects become smaller, the surface-to-volume ratio increases, changing the relative strengths of these two common forces. At the very small scales, such as the micro- (cells) or nanoscales (molecules), the stickiness property completely dominates. This activity demonstrates a crossover point from the dominance of gravity for big objects (sugar cubes) to the dominance of adhesion for smaller objects (powdered sugar grains).

Captivating Cubes: Investigating Surface Area-to-Volume Ratio
By: M. Gail Jones, Amy R. Taylor, and Michael R. Falvo
Grade Level: High School, Middle School
In this two-part activity, students investigate how surface area-to-volume ratios change with cube size. Students apply those calculations to explore how surface area-to-volume relationships limit the size of cells. Extensions of these activities probe the role that surface area-to-volume relationships play in science contexts.

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.

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.

The Vision of Animals
By: David Ipsen, Gretchen L. Gillfillan, Judy Diamond (Revised New Edition), Robert Stebbins, and Judy Scotchmoor (Revised New Edition)
Grade Level: Middle School
In their study of animal coloration, the students will be “hiding” animals from themselves. If the students cannot easily spot a fish, they may assume that the fish will be overlooked by another fish or by a preying bird or mammal. If a moth escapes the students’ attention, they may assume that the moth will be likely to escape the attention of its real predators. This activity questions such assumptions. This free selection includes reproducible...  [view full summary]
