Motion in a Circle
High schoolers study about deriving centripetal acceleration for motion at constant speed around a circle.
Curated OER
Motion in a Circle
Students explore uniform circular motion, and the relation of its frequency of N revolutions/sec with the peripheral velocity v and with the rotation period T. They examine how uniform circular motion is a type of accelerated motion.

Patterns In Fractals
Middle schoolers find number patterns in the generation of several different types of fractals.
Curated OER
Lines, Rays, Line Segments, and Planes
Students are introduced to lines, rays, line segments and planes and study the differences between them. They also practice graphing lines, rays, line segments and planes
Curated OER
Lewis and Clark: The Language of Discovery
Students replicate some of the trailblazing methods of Lewis and Clark on a fifteen-minute "writing journey" through the school or neighborhood.
Curated OER
Chilly Discoveries
First graders make ice cream and determine what makes this liquid turn into a solid.
Curated OER
Negotiating Treaties
Eleventh graders recognize the interaction between early settlers and indigenous people in the U.S. They recognize the impact of the Indian Removal Act on displaced Natives in the early West and the impact on Native attitudes today.

Plants -- What Are Their Parts and Functions?
Middle schoolers identify the parts of a flowering plant and their functions. They describe its life cycle as well. They compare the parts of the plant to the roles that are needed in a democracy.
Curated OER
Time-Axis Fallacy and Bayes Theorem
Learners determine that knowledge of an event's outcome can affect the probability of the unknown outcome of an event that has already occurred.

Exploring Our Solar System #1
Students examine the different theories on how our solar system was formed. They discover the order of the nine planets. They also identify the surface features of each planet.
Curated OER
Bead It!
Fourth graders use colored beads in two problems and explore the use of proportional reasoning as a problem solving method. Working Students, in groups, explain their reasoning strategies orally, and through drawings.
Curated OER
Why Mosquitoes Buzz in People's Ears
Students appreciate African folktales, make "connections" between geography and literature, and research facts about Africa's animals and present findings through art and writing.
Curated OER
Gonna Take a Sedimentary Journey
Learners collect water samples from a local source, test it, filter it and identify the materials suspended in it. Students disucss the possible sources of sediment in their watershed.
Curated OER
What's That Brown Fuzzy Stuff On My Plum?
Students examine Koch's Postulates by actually using them. They perform each of the required four steps to show that the brown fuzzy fungus they see growing on stone fruit (plums, peaches, nectarines, cherries) is what causes them to rot.
