Students identify how the different plants and animals work together to cause the changes in the log. Students discuss the sequence of events in the life of the tree and log. Students plant a seed to take home and care for. Students...

Learners discover how to estimate the age of redwood trees. They measure the trees' diameters by using string to calculate the circumferences. Students conclude by discussing the science of dendrochronolgy.

Fifth graders estimate the size a population (ecosystems) Students make a chart from information collected then create a graph (line or bar) from this information. Students do a lesson where they observed, examine, and record data...

Third graders design and make clocks compiling a materials list, creating adesign portfolio, and recording progress in a daily log. After making a full-size drawing of their clocks and with the assistance of high school technology...

Learners become forensic investigators. In this crime scene lesson, students go to the science lab which is the "scene of the crime." They collect evidence such as fingerprints, "blood" evidence, chromatography, footprints, and more. 

Students make observations of effigy mounds and record them in a notebook. In groups, they must determine the scale of measurement and create their own grid to scale part of the Effigy Mounds National Monument. They also practice using...

Students use the macro mode of the OLYMPUS FE-140 CAMERAS as virtual microscopes to explore different habitats, observe plants, soil, and insects and other creatures. They download those images on electronic files and build web pages....

Learners investigate woodbugs. In this scientific investigation instructional activity, students explore the steps scientists take when conducting an investigation using live specimens. Learners explore habitat preferences for woodbugs...

Students discover the reproductive parts of a plant.  In this biology lesson, students identify and categorize several different plants they dissect in class.  Students record their information using a data chart.

Learners create a map. In this direction and distance lesson, students come up with familiar places in the community and calculate the distances from these places to the school. Learners create a map that displays these places and their...

Learners explore the population of grass plants in a given area. They plan and conduct a sampling activity to estimate the population of dandelions or the number of grass blades on the school grounds.

Students examine how the environment influences tree growth. In this tree instructional activity, students analyze the growth of rings to see how plants adjust to adverse conditions in order to survive.
