Curated OER
Forces and Newton's Laws Unit
Students participate in lessons on Forces and Newton's Laws by selecting activities and assignments to complete in a Layer Unit. Students select assignments and activities in the C Level, B Level, and A Level.
Curated OER
Particle Models in Two Dimensions
In this motion worksheet, students draw and label the trajectory of objects including the x-component and y-component of the velocity. Students calculate acceleration and speed. This worksheet has 7 problems to solve.
Curated OER
Intro to 2D Motion
Students study straight line motion and motion due to gravity. In this motion lesson students analyze several experiments.
Curated OER
Rube Goldberg Project
Learners apply inquiry and problem solving approaches in science. They design a device (invention) that solves a special problem.
Curated OER
Eratosthenes And Radius of the Earth
Students calculate the radius of the earth. They use the method and data suggested by Eratosthenes. They investigate the interrelationships among mass, distance, force, and time through experimental processes.
Curated OER
Introduction to Forces and Inertia
Students explore the basic underlying concepts of Newton's first law of motion. They discuss forces and brainstorm different examples of force and what they act on. Students examine force by observing springs and gravity. They discuss...
Curated OER
Intro to 1D Kinematics with Physlets
Twelfth graders examine illustrations and animations on a Physlets CD in which they must describe motion, analyze graphs, and calculate initial velocity. The Physlet assists in providing active class participation in discussion.
Curated OER
Accelerated Frames of Reference: Inertial Forces
Students examine how when applying the laws of motion to an object in an accelerating frame, using coordinates defined in such frame, one must always add an "inertial force", representing forces caused by the frame's acceleration.
Curated OER
Looking into Eratosthenes' Radius of the Earth
Pupils, in small groups, research Eratosthenes and his calculations of the Earth's radius. They write a summary of the person, the experiments and his calculations to determine how accurate Eratosthenes was in his estimations of the size...
Curated OER
Drag Problem Set
Students read an explanation from a NASA Web-based textbook and then demonstrate an understanding of the text by applying it to calculating drag of both full-sized and model gliders.
Curated OER
On the Move
Young scholars see if they can get their perceptions of movement expressed in images.
Curated OER
Newton's Law of Universal Gravitation
Learners explore the nature and magnitude of gravitational forces. In this gravitation activity students study gravity and answer questions.
