The Tangent Ratio
Students calculate the tangent ratio given a right triangle. For this trigonometry lesson, students use a right triangle and the Pythagorean Theorem to solve problems.
Curated OER
Leonardo da Vinci
Students select appropriate tools and technology to perform tests, collect data, and display data. They construct appropriate graphs from data and develop qualitative statements about the relationships between variables.

Gravity: It's GREEEAAATTT!
Students calculate effects of gravitational force on planets, discuss the effects of weightlessness on the human body and describe and demonstrate how objects in a state of free fall are accelerated by gravity at an equal rate.
Curated OER
Betweenness and the Sum of Parts
High schoolers differentiate lines and angles using betweenness in this geometry instructional activity. They differentiate angles and lines using Cabri Jr. and analyze the data and make conjecture.
Curated OER
Transformations: Translations
Students perform transformations and translations using polygons. In this geometry lesson, students perform transformations on a coordinate plane. They identify the image and pre-image of each figure.
Curated OER
Make a Classroom Map
Learners map the items in their classroom to explain the importance of coordinate systems.
Curated OER
Volume and Surface Area: Which Is More?
Students explore the volume and surface area of three dimensional figures. Through the use of video, students discover three dimensional shapes, their uses in real-life applications, and methods used to calculate their volume and surface...

Longshore Current
Learners are posted at the beginning and end of a 10-meter long line parallel to the ocean and are instructed to look straight ahead towards the water. The student at the beginning of the line uses a stopwatch, goes to the water's edge...
Curated OER
How Far Did They Go?
Students create a map. In this direction and distance instructional activity, students come up with familiar places in the community and calculate the distances from these places to the school. Students create a map that displays these...
Curated OER
What did I find?
Students excavate an artifact. In this archaeology instructional activity, students get a bucket filled with dirt and a broken up artifact. They work in groups to take it out and to find what its purpose was. 
Curated OER
Lines in the Coordinate Plane
Students graph lines in a coordinate plane. In this geometry lesson, students graph lines on a coordinate plane, and identify the slope. They classify the lines as parallel or perpendicular and write an equation of a given line.
Curated OER
Touring Delmarva
Young scholars plan a trip.  In this trip planning lesson, students use a map to find where they would like to visit with a pretend family of 4. They get a specific amount of money and time and need to decide where they will stay...
Curated OER
Surface Friction and Wear Characteristics of Common Materials
Students identify the factors affecting friction. In this physics lesson, students construct their own rocket car and race them. They graph the average speeds and discuss how lubricants affect friction between rubbing surfaces.
Curated OER
How Hot Is It?
Fourth graders practice estimating temperatures. They practice in Celsius and Fahrenheit.
Curated OER
The Three Little Pigs' Straw House
Second graders design and sketch a model house. In this technology lesson, 2nd graders construct their house using teacher provided materials. They present their finished project and explain their design in class.
Curated OER
A Real Difference
Fifth graders use the Celsius and Fahrenheit thermometers to compare temperature readings. They use the Internet to find the temperatures of selected cities. After data is collected for five days, 5th graders graph the temperatures.
