Global Harmony
Young scholars listen to world music samples and try to identify the countries of origin; students work in small groups to design an online "world music caf??."
Curated OER
Birds
Pupils study birds and examine the idea that they evolved from reptiles or dinosaurs. In this birds lesson students divide into groups and research one side of the debate, then at the end have the pupils debate each-other.
Curated OER
Inscribed Angles
Students analyze inscribed angles and intercepted arcs and explore the relationships between the two. They investigate the properties of angles, arcs, chords, tangents, and secants to solve problems involving circles.
Curated OER
Parabola with Horizontal Directrix
Students find the vertex, directrix, and focus of a parabola. They graph parabolic functions and solve application problems involving parabalas.
Curated OER
Parabola With Horizontal Directrix
Young scholars find the vertex, directrix, and focus of a parabola and graph parabolic functions. They solve problems involving parabolas after a demonstration lesson plan by the teacher.
Curated OER
Problem Solving in Mathematics
Seventh graders discover that there are multiple strategies to be used in problem solving. They explain a problem solving situation in their own words and determine a possible strategy for solving the problem.
Curated OER
Are You Absolutely Sure of the Value?
Seventh graders develop an examineing of absolute value through real world situations. They develop an examineing of when absolute value can be used in a given situation.
Curated OER
What Happens on Average
Fifth graders are introduced to convergence of sequences based on averaging previous terms in the sequence. The power of the "fill-down" function in spreadsheets is exploited. By using various starting numbers, and inferring the limit,...
Curated OER
Exploring Centers of a Triangle: Part 1
Students use problem solving skills, formal geometry, and The Geometer?s Sketchpad. They model and solve two real-world problems by constructing the in center and circumcenter of triangles.
Curated OER
Exploring Geometric Constructions of Parabolas
Learners are introduced to the construction geometrically of parabolas. Using a software program, they identify lines, segments and midpoints. They label the parabolas properties and characteristics and use a formula to determine the...
Curated OER
Minerals
Students explore the concept of minerals. In this minerals lesson, students discuss how cooling affects the size of crystals. Students discuss how the structure of minerals is a tetrahedron. Students discuss the structure of silicates...
Pennsylvania Department of Education
Creating Polygons
Students describe, make and compare polygons. In this creating polygons instructional activity, students identify properties of quadrilaterals and describe common features of two dimensional shapes.
Curated OER
Why is Roosevelt on the Dime?
Learners use a variety of reference resources to research the life of Franklin Roosevelt. From this research, they determine why his image was chosen to appear on the dime.
Curated OER
Curveball vs. Fastball
Learners 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
The Baseball and Air
Pupils use Curveball to complete the activity to determine how the speed of airstreams changes in relation to changes in the distance of the airstream from the center of the baseball.
Curated OER
Lift vs. Airspeed
Learners, after reading the explanation given below, use FoilSim and a graphing calculator to complete the activity to determine the relationship between airspeed and lift of an object by interpreting data.
Curated OER
Expected Value
Students explore expected value, are introduced to the concept of varying payoffs, and have used a computer simulation of a "real world" example where expected value is used
Curated OER
Statistics and Shopping
Students examine statistics and data analysis concepts from the practical questions that arise in everyday life.
Curated OER
Age Structure Studies
Students collect data from Internet sources to compare age distributions in their city, county or state with that of other places in the US or other countries. They construct and interpret age-structure population pyramids and research...
Curated OER
Newton's Second Law: Mass-Acceleration Relationship with Dynamics Carts
Students form their own hypothesis about the relationships between force, mass, and acceleration for their dynamics cart system. They collect data and express it in a graphical format to visualize the relationships.
