Finding the Formula and Percent Composition
Do you have mole problems? If so, call Avogadro at 602-2140. The lesson starts with pupils working independently to solve for molar mass of ionic compounds. Then they learn to solve for percent composition and later perform an...

Energy and Entropy of a Stretched Rubber Band
Stephen Perry invented and patented the modern rubber band in 1845. Young scientists put his discovery to work as they use rubber bands to observe entropy and enthalpy. They determine the change in free energy to figure out if it...

Studying Fossils: Hominoid Skull Comparison
Learners collect data on the differences in Hominid skulls using acrylic casts of fossil skulls. They measure a series of structures on skulls from six different species then use the data to determine evolutionary relationships between...
Curated OER
What a Cosmic Web We Weave
Students explore, using journals and discussion in small groups, how the universe has evolved since the theoretical Big Bang and create dramatizations of various eras in cosmic evolution.
Curated OER
Reaction Kinetics and Rate Laws
In this reaction kinetics worksheet, students draw a graph of energy vs. reaction progress and determine the factors which change the speed of a reaction. Students learn about rate laws. This worksheet has 1 graph, 15 fill in the blanks,...
Curated OER
Time Machine: Evolution, Geology
Students are taken on a simulated "voyage" backward in time, to the beginning of our planet. They "witness" that beginning, the origin of life, and a number of key events from then to the present.
Curated OER
Investigating Evolutionary Questions: Bats, Whales, Reptiles, Birds, Animal Classification
Students are guided through a process in which three questions are addressed by retrieving beta hemoglobin sequences from online databases, and using online tools to compare those sequences in student-selected animals.
Curated OER
Examining the Fossil Record
Students create an evolutionary tree based on fossil morphology and their ages. In this fossil record lesson plan, students are given 23 pictures of fossil. They study their morphology and arrange the fossils by age and structures on a...
Curated OER
Using Concept Maps to Teach Evolution
Students encounter concept maps for reviewing evolution. Concept maps provides an alternative method of interacting with the information and a forum for asking questions about vocabulary, concepts and interrelationships. A quiz is...
Curated OER
Inside an Atom
In this atom worksheet, students read about the history of the discovery of the atom. Students write a story, poem, song or other creative project in which they shrink to an incredibly small size and are trapped in a carbon atom.

VARVES: Dating Sedimentary Strata: Geology, Paleontological Patterns
Learners count the number of varves (annual layers of sediment) in shale billets, taken from the Green River Formation in Wyoming. The count is then extended to reflect the entire 260 meters of sediments where the billets originated.
Curated OER
The Rise and Fall of the Mammoths
Middle schoolers develop an understanding of the evolution of species in the context of the woolly mammoth. They examine the fossil record to explain natural selection.

They're more evolved that way
Young scholars explore the notion of local evolution, or genetic selectivity among different continent-based human populations. They consider specific examples of local evolution, such as lactose tolerance, skin color, and cognitive...

Scavenger Hunt: A Group Collection
Students be complete a collection of living organisms and systems from the school campus.

Time Conceptualization
Students use this activity to establish a new mode of reference to the conceptualization of time. To present hominid evolution in terms of millions of years and endosymbiosis of eukaryotes in billions of years carries little meaning to...
Curated OER
Human Evolution
Students recognize that achievements of human beings throughout human history can be considered part of the ongoing story of human evolution. They research settings such as the biosphere and Mars and write imaginative short stories using...

Expansion of solids
Seventh graders relate knowledge of the particle theory of matter to observations of the expansion of solids. They watch a demonstration of heat with a copper ball and hoop. They watch a second demonstration with a bimetallic strip.
