Students compare a series of satellite images taken 3-4 years apart to investigate the effects of human land use. They annotate the images using ImageJ software and use the annotated images to explain their findings.

Students measure a topographic and geologic cross-section across a floodplain by simple surveying and auguring techniques. They consider the spatial context of the field observations, use GPS measurements, and desktop GIS analyses.

Students work with data from a seismic wave model in a freely available GIS (geographic information system) program, ArcVoyager SE. Using a GIS, they examine maps and produce graphs to explore variations in seismic wave velocities at...

Students import ocean bathymetry data from text files. They then graph these observations along with model predictions to assess the model's ability to simulate observed topographic features of the North Atlantic. Students use Excel to...

Young scholars explore basic methods of GPS data collection, uploading the data to a computer, and making simple maps of their data using GIS software. They create a map of the data using GIS software (or Excel)

Students collect samples in the field, analyze them using various tools and instruments, then present their results and interpretations. They examine igneous and metamorphic rocks in detail and interpret petrologic data.

Students conduct a regional watershed analysis of an area of their choosing. Using on-line data and their personal knowledge of the area, they determine the annual hydrologic budget and teach the class about "their" watershed.

Learners make observations and present interpretations based on their observations and on their prior knowledge. They use images to answer questions and make formulate hypotheses.

Students use a JAVA interface to explore the Daisy World model to illustrate a mechanism through which - according to the Gaian hypothesis - biota might optimize their abiotic environment by means of negative feedback.

Students import US Historical Climate Network mean temperature data into Excel from a station of their choice. They are guided through the activity on how to use Excel for statistical calculations, graphing, and linear trend estimates.

Learners design and construct an imaginary animal that is perfectly adapted to a particular type of biome. They give the animal a scientific name, place it in a phylum and write descriptions about its behavior, reproduction, foraging,...

Seventh graders practice the evaluation component of the scientific method while comparing and contrasting the similarities and differences of the food chains and webs of polar animal life. They study about classification and ecology...

Young scholars, through hands on games and activities, discover how bats live and how bats benefit ecosystems. They play a game designed to show them how echolocation works and another to show how mother bats locate their young through...

Second graders examine the physical characteristics of the different states of matter. In this chemistry lesson, 2nd graders observe how matter changes from one phase to another. They classify substances according to its type of matter.

In this amphibians activity, students click on the links in the questions about amphibians to find the answers to the questions and then come back and answer the questions. Students answer 10 questions total.

Young scholars explore the anatomy of frogs. They complete a frog dissection to complete an accompanying worksheet which includes questions, diagrams and pictures.

Students identify some of the most important native and introduced species of animals in the United States. They describe how animals populations of cities have changed over time, outline the benefits and problems associated with...

Young scholars sample a site with low human impact, one with moderate human impact, and a third with high human impact. Students chart the data for each site and then compare the sites and discuss.

First graders plan and create a model zoo depicting the natural habitats of animals. Their models include animals and a display of written factual information about the animals. Students present their project by conductig a tour of...

Students observe the two major developmental pathways (protostome and deuterostome). They analyze data regarding differences in nucleotide sequences and construct a phylogenetic tree. They observe the similar evolutionary history shared...

Students learn about the parts of the eye.  In this eyes and vision lesson, students the story Arthur's Eyes and create a KWL chart about eyes.  Students label the parts of the eye, examine the eyes of different animals to...

Learners are able to recognize a wide variety of fruit and have a greater understanding as to the importance of fruit in their diet and that some fruits skin are edible and others are not.

Second graders explore the properties of primary color and investigate what happens when primary colors are mixed. They listen to the story The Crayon Box That Talked and list the colors. They experiment mixing primary colors and...

In this grouping and sorting worksheet, students learn about sorting objects and living things into larger and smaller groups. They complete an exercise in which they sort cutlery, and then students answer the 3 questions on the page.
