Virial Theorem Lesson
Ninth graders describe how equilibrium can occur as the balance of two effects. They model the stability of elliptical galaxies based on how fast stars within the galaxy are moving.
Curated OER
Mystery Machines
Students explore simple machines and demonstrate thier acquired understanding by building a simple machine.
Curated OER
Parachutes And Parafoils
Pupils study deceleration devices like parachutes and parafoils.
Curated OER
Urban Impact on Chollas Creek (California): A Field Study
Students, in groups, take samples from a creek and keep a field journal on their samples. They also perform tests on their samples.
Curated OER
Our Universe: Always Moving, Always Changing
Students explore the main concepts of astronomy through the eleven lessons of this unit. The past, present, and future methods of studying the science are examined in this unit.
Curated OER
Sediment Tubes
Students observe how different density soils and rocks behave in wind and in water. They make predictions and careful observations as they explore sediment transport and sediment rates in streams and rivers.
Curated OER
Watch It Slide!
Students work together to examine inclined planes. They create a plan to raise rocks to build pyramids. They discover the changes that occur when the angle is increased or decreased.
Curated OER
Propulsion Pop!
Learners demonstrate an understanding of the text by completing a propulsion activity, charting the results, and answering questions that demonstrate an understanding of rocket propulsion.
Curated OER
Design of Airfoils and Problem- Solving Using FoilSim
Ninth graders, after reading the explanation given below, complete the problem-solving activities to demonstrate an understanding of the concepts presented.
Curated OER
Collisions Lesson
Tenth graders explore the role that collisions and near collisions of galaxies play in determining the shape of galaxies. They model the collision of disk shaped and spherically shaped galaxies.
Curated OER
Deceleration of a Toy Truck
Eighth graders complete labs using toy trucks to study deceleration, record thier data, and then transfer it to graphing software to produce a graph. They create a lab report of the completed lab using a word processing program.
Curated OER
Learning Lesson: Crunch Time
Students demonstrate the effect of heat on pressure. They use a 2-liter bottle and hot tap water to complete the experiments. They also discuss thunderstorm safety rules.
Curated OER
How Do I Get a Pure Sample of the Molecules I Make?
Students initially engage in online research and consult print materials to identify a compound to produce. Once a selection has been made, individually, students conduct lab experiments to isolate substances. The end product is a...
Curated OER
Good Vibrations
Students demonstrate sound waves and make changes in the waves
resulting in changes in pitch. Students associate changes in pitch in various "musical instruments"with size and shape and the sound waves they produce.
Curated OER
Measurement of the Depth of the Ocean
Students comprehend the physical properties of pressure and Boyle's Law by designing a depth gauge. They construct a capillary depth gauge and calculate the calibrated depth marks of the capillary tube. They determine the margin of error...
Curated OER
Wandering Wild-oats
Students observe wild-oat seeds. In this biology lesson, students watch how wild-oat seeds react to moisture and draw conclusions and make predictions.
Curated OER
Fun with Balloons
Fifth graders design their own hot air balloon. In this science lesson, 5th graders investigate how factors like weight and sizes affect a balloon's lifting power. They also write math problems based on facts written in the book "The...
