The Flame and the Atom:
Young scholars investigate the structure of atoms. Students read information about the Rutherford model, the Bohr model, and the Quantum Mechanical model examining each for its scientific validity. They watch a PowerPoint presentation of...
Curated OER
Tadpoles
Students examine tadpoles at various stages of development. They make careful scientific observations and compare the changes that occur at five different phases of a frog's life.
Curated OER
Matter
Fifth graders investigate the structure of matter. They examine pictures of atoms and molecules and discuss their relationships, and construct a model of a molecule using toothpicks and gumdrops.
Curated OER
History of Atomic Theory
Young scholars study the significance of the quantum model and how scientific theories adapt over time. In this investigative lesson students describe the contributions that scientists have helped develop the atomic theory and...
Curated OER
Principles of Flight
High schoolers explore the principles of flight. In this flight lesson, students construct a model plane and investigate the forces acting on the flier. They will measure the thrust and calculate the stored energy.
Curated OER
Cyclic Universe: Worlds Without End
Students compare and contrast the Big Bang Theory and the Cyclic Universe Model. They explain basic properties of the univers which make life possible. They evaluate ideas about the origin of the universe as to their scientific value.
Curated OER
The Earth-Sun-Moon System
Third graders construct a model of the earth-sun-moon system using students as the sun, moon, and earth. They discuss ways that time is related to the movement of the earth and moon.
Curated OER
Crustal Sinking
Pupils measure the rate of sinking of a test tube into a beaker of "glop", representing a model of the interaction between the Earth's crust and upper mantle. This task assesses students' abilities to make simple observations, collect,...
Curated OER
Circular Motion
Students research physical science by completing worksheets. In this gravity lesson, students read assigned text regarding the rotation of Earth and the gravitational force caused by the speed of which it rotates. Students complete a...
Curated OER
Exploring the MapleCopter
Study explore the motion of maple seeds and design experiments to explain their spinning flight patterns. They make observations, explain ideas of motion, use models, analyze previous reports and experiments, identify relevant factors...
Curated OER
Historic Earth Science Innovations
Students research the demands or limitations on Earth scientists. In groups, they design and build a model that would be useful to them in the lab or field. They share their model and their ideas behind it to the class and answer any...
Curated OER
Untitled Document Aerospace Team Online:
Students explain the historical significance of use of the scientific method in developing the first airplane and appreciate the process involved in developing a new technology.
Curated OER
What Are the Characteristics of Biomes?
Students working in groups study different types of biomes and the issues or environmental problems that can affect them. They design a poster board that displays the characteristics of their biome. They make a model of the biome that...
Curated OER
Testing the Caverns
Students build model caverns using paper mache or clay and bury them in a tray of sand. They test the models by dropping balls onto them to simulate an asteroid hitting the earth. They evaluate the effectiveness of a structure against...
Curated OER
