# Bird Beak Accuracy Assessment

In this activity, students quantitatively evaluate the accuracy of a classification and understand a simple difference/error matrix. Students sort birds into three possible classes based on each bird’s beak: carnivores (meat eaters), herbivores... (View More)

# Plate Tectonics and Volcanism

This is a lesson where learners explore plate movement and the relationship between plate tectonics and volcanoes. The lesson models scientific inquiry using the 5E instructional model and includes teacher notes, prerequisite concepts, common... (View More)

# Classification: Family Ties

This lesson is comprised of three parts grouped to enable student understanding of classifying organisms. In part one of the lesson, students classify imaginary organisms represented by a mix of breakfast cereals, candies, nuts, raisins, etc.... (View More)

# Size and Shape

Size and shape are important in astrobiology. In this activity and slideshow, students observe the importance of relative size and morphology in identifying microscopic structures when viewed with the scanning electron microscope. This activity is... (View More)

# Classification: Time for a Change

In this activity, students develop a timeline relating technological advances, particularly in microscopy, to how scientists have classified living organisms throughout history. Students use Internet and/or library resources to investigate important... (View More)

# Extremophiles: Its Just Right

In this activity, students will observe the relationship between temperature and metabolism. The subjects for this experiment are Saccharomyces cerevisiae, one-celled organisms more commonly known as baker's yeast. By observing the presence of... (View More)

# Is Life On Mars Possible and Could Humans Establish Settlements There?

Searching the six satellite images of Mars provided in this investigation, students identify and locate areas that possibly sustained life in the past, might now sustain life, or could in the future. The URL opens to the investigation directory,... (View More)
