Curated OER
Layers of Rock
Juvenile geologists drill clear plastic straws down into a playdough sedimentary rock model, pulling out sample rock cores. As they analyze their cores, they apply the law of superposition and discover that originally horizontal layers...
Bowels Physics
Projectile Motion
Hit a bullseye with an engaging presentation about the components of projectile motion. Viewers see how horizontal and vertical motion combine to create the parabolic path of projectile motion.
CK-12 Foundation
Irwin 2D
Learners explore two-dimensional motion through visual modeling with an interactive lesson that allows them to control the path of a robot. Graphs show both the horizontal and vertical motion as the robot continues through its entire route.

Velocity Problems
In this velocity activity, students determine how far a bullet falls before it hits its target 180m away. Then they determine the initial velocity of a ball hit at 45 m/s at an angle of 45 degrees above the horizontal. Students also...

Following Gene Transfer by Conjugation in Bacteria
After the lab, you'll be able to solve this analogy: Natural selection is to vertical transfer of genes as ___ is to the horizontal transfer of genes. Young biologists conduct an experiment on E. coli bacteria to explore the process of...

Unit VI: Worksheet 2 - Force, Velocity, Displacement
Future physics majors look at a diagram of a marble rolling across a railing. They sketch motion maps and force diagrams. They determine the horizontal range of the marble as it falls to the floor. Then they double the height and repeat...

Geologic Mapping I
Students create a geologic map and cross-section of an area of horizontal sedimentary rocks, exposed in several locations. Map must include a complete key or legend with rock descriptions of the various formations.
NOAA
Weather Word Find
Weather isn't just for small talk anymore! Diagonal, horizontal, frontward, backward, up, and down; learners discover the ways 40 weather-related words are hidden in a word search.
McGraw Hill
Escape Velocity Interactive
How hard do you need to throw a ball in the air so that it never returns? Scientists call this measure the escape velocity. Classes can explore this concept through an intriguing interactive lesson. Pupils adjust velocities and observe...
CK-12 Foundation
Sprinter
Why do sprinters wear spiked shoes? Scholars explore various styles of shoes and how they handle forces when running. Scholars adjust variables including shoe type, horizontal force, surface type, and normal force to determine which...
CK-12 Foundation
Water Fountain
Most water fountains are designed to keep the water inside the fountain, but how are they designed to shoot up and out without the water leaving the fountain? Scholars vary the launch angle, fountain height, launch speed, and catcher...

Broken-Line Graphs: Heating Curve of Water
Examine the unique graphs coined broken-line graphs. Using the phase change of water for data, learners answer questions related to the temperature and energy at different times in the cycle of the phase change. Questions focus on the...
Concord Consortium
Crooke's Tube
Behold, the electron is discovered! Take young scientists on a journey back through time to examine JJ Thompson's famous experiment using a Crooke's tube. Pupils manipulate the charge on the apparatus' horizontal plates, observe cathode...

Kicking Machine
Don't kick the resource to the curb; you'll definitely regret it. Future engineers devise a kicking machine that launches a ping-pong ball toward a target. They can use a pendulum, a rubber band, or both, depending on whether they want...
Physics Classroom
Trajectory - Angle Launched Projectiles
Horizontal and vertical speeds change as projectiles move through space. As part of a series on vectors and projectiles, scholars create vector diagrams to compare these speeds at various locations. They they determine the values for...
Purdue University
Sun Tracking System for a Solar Panel
Capture the Sun's rays as best as possible. An engaging STEM instructional activity teaches scholars about how Earth's tilt causes the path of the sun to change throughout the year. They create solar panel systems that move both...

Mask of the Black God
Finally, an astronomy lesson for the high schooler! Explorers are able to read star maps for finding objects in the night sky by determining celestial coordinates. In particular, they locate the Pleiades and read about a Navajo legend...
Curated OER
Big Air Rules
Students discuss projectile motion using a basketball player taking off for a slam dunk, a fly ball launched off a hitter's bat, and a snowboarder flying off a pipe as examples. The lesson is expanded by introducing the mathematical...
