Addition To Fifteen
In this math worksheet, students solve problems using the operation of addition to find the sums. The sheet is a teacher's guide.
Curated OER
Altitude and Flight Forces
Students use the World Wide Web to access and use FoilSim. They also use the World Wide Web to access the NASA Glenn Web site for information relative to the factors involved with the flight of an airplane.
Curated OER
Rotation Sensor Challenge
Pupils participate in a challenge to construct a rotation sensor with the highest degree of accuracy and repeatability. They conduct computer analysis of their sensor using repeated trial.
Curated OER
Mass & Velocity Effect
Pupils, after reading the explanation given below, use FoilSim to complete the activity to fulfill the specifications of a given airfoil and then plot and interpret graphs.
Curated OER
Curveball vs. Fastball
Students graph the relationship between the release point and the final position of curveballs and fastballs thrown by both right and left handers given a constant speed, and explain the relationships illustrated by the graphs of data.
Curated OER
Wing Specifications
Ninth graders use FoilSim to fulfill the specifications of a given airfoil (wing) and plot and interpret graphs.
Curated OER
Wing Area Effects Problem Set
High schoolers read an explanation from a NASA Web-based textbook on lift and an explanation on the FoilSim software package given below. They use FoilSim to evaluate the relationship between wing area and lift.
Curated OER
Velocity Effects Problem Set
Students, after reading an explanation on lift from a NASA Web-based textbook and an explanation on the FoilSim software package given below, use FoilSim to evaluate the relationship between velocity and lift.
Curated OER
When Things Heat Up
Ninth graders investigate relationship between the temperature and concentration of dissolved oxygen in water. They examine how pollution and other natural influences can cause the parameters to change. In groups, 9th graders collect...
Curated OER
Mirrors and Lenses
Students identify the characteristics of mirrors and lenses. In groups, they describe the types of images formed by converging and diverging mirrors and calculate the magnification of a spherical mirror. They follow the same procedure...
