The "Nuts and Bolts" of Taxonomy and Classification
Students develop classification scheme that meets the established rules of the Linnaean system. They write one page essay on classification choices.
Curated OER
Field Experiments on Succession
Student develop a hypothesis regarding the effects of either mowing or fertilizer upon the diversity of plant species in a grassland ecosystem. They set up experiment field plots and measure species richness.
Curated OER
Ocean Currents
Students label the names, relative temperature, distribution, and direction of flow of major ocean currents on a world map. They also explore and model the natural forces that affect the movement of ocean currents through demonstrations...
Curated OER
Wacky Water Critters
Students visit a local creek or stream. They collect water samples from the creek and observe and sort the "water critters" they find in the sample, observing smaller organisms under a microscope if necessary. They identify each organism...

How Do You Move Along the Earth?
Students determine their own walking and running velocity. In this physics lesson plan, students calculate velocity using distance and time information. They compare human and animal speeds.
Curated OER
Activity Two Teacher Page: Explosions
Students identify variables that affect the system, and specify which variables are independent and which are dependent.

Analysis of Lobster Claw Function. An Exercise in Biomechanics
Students observe two chelae. They write three differences they observe in their notebooks. Students suggest a hypothesis which would explain these differences. They dissect the chela. Students analyze the lobster claw as a mechanical lever.

Whose Brain is THAT?!
Students explore various animal brains. In this animal anatomy lesson, students compare and contrast animal brains with the brain of a human. They record several characteristics in a data table for each brain they observe.

Solar Race Cars
Students explore the relationship between time traveled, distance and speed. In this solar race car lesson students wire solar batteries using series and parallel circuitry.
Curated OER
Lenses and Telescopes
Students examine telescope construction. In this telescope lesson, students examine the lenses used in telescopes by exploring with convex and concave lenses.
Curated OER
Forces and Masses and Motion, Oh My!
Learners explore how varying force and mass effect the motion of an object. In this motion lesson students participate in a class activity and demonstrations.

It All Starts With a Seed
Students use laboratory equipment safely. They identify structures in a seed. They distinguish between monocots and dicots. They search for information using the computer.
Curated OER
Ohm's Law
Students explore Ohm's Law. Following given instructions, students build a physical model of a conductor. They observe a relationship between the current, voltage and resistance in a conductor. After experiments, students explain the...
