Spy on a Spider
Students view slides or live specimens to name and describe the distinguishing features of groups of arthropods, especially spiders and insects. They complete worksheets, observe webs and then search for and record where spiders can be...
Curated OER
Egg Measurement
Students explore measurement and units. They measure eggs to determine their density, mass and percent composition. An inquiry approach is used for students to ascertain the mass.
Curated OER
Soil Organisms
Students work together to collect soil samples from different locations. In the samples, they identify the macroorganisms and classify them. They identify the conditions that affect how macroorganisms grow. They also analyze and identify...
Curated OER
Munching Insects
Learners design an experiment to discover what types of plants particular insects prefer. They comprehend that insects eat only specific plants and that this has particular implications for noxious weeds. Students observe and collect...
Curated OER
Termite Lab
Students examine insect behavior in a lab activity. Students explore the idea of chemical specificity and the reactions of termites to a chemical found in their trail pheromone. Students watch a demonstration with termites before...
Curated OER
Selecting Soil Organisms in Compost
Students conduct an experiment to demonstrate that many of the enzyme systems needed to break down society's wastes exist in nature among the decomposers in a compost pile. They culture compost bacteria on starch agar to examine the...
Curated OER
Pollen Tube Growth
Students demonstrate the proper usage of the compound and dissecting microscopes. They identify the parts of a flower and the functions of the flower parts. Students describe the process of gamete formation and fertilization in a flower.
Curated OER
UV Radiation and the Developmental Stages of Red Flour Beetles
Students perform an experiment to compare the sensitivity of the various developmental stages of Red Flour Beetles to ultraviolet radiation. Larvae, pupae and adult beetles are exposed to a source of UV-B radiation. In groups, they...
Curated OER
The Effects of Ultraviolet Light on Lumbriculus
Students explore the effects of ultraviolet light on Lumbriculus. They expose ultraviolet light to Lumbriculus (worm) and determine the lethal exposure time. They examine the worm and record their observations.
Curated OER
Selecting Soil Organisms in Compost
Students demonstrate that many of the enzyme systems needed to break down--and therefore clean up-society's wastes already exist in nature among the decomposers. They select the best starch-munching organisms by altering the environment...
Curated OER
Physiology Activity Perception and Behavior
Students conduct an experiment to determine a fly's ability to detect sugar, its behavioral response, how a previous experience may alter the response, if a fly can be tricked, and how human sensitivity compares to a fly.
Curated OER
Who Lives In The Water
Students investigate the environment of a stream or lake to collect and observe macroinvertebrates in their natural environment. They record data and summarize the information obtained. Students look to see if there has been any human...
Curated OER
Missing Macroinvertebrates
High schoolers investigate the concept of a macroinvertebrate. They observe the presence of increases or decreases in population in order to test for factors that contribute to the extinction of a species. Students predict the likelihood...
Curated OER
Pond Exploration
Pupils take a hands-on approach to explore the world beneath the water in this activity. They examine the creatures they catch to study about the adaptations these animals have that allow them to survive in this harsh environment. They...
