Watch It Slide!
Students work together to examine inclined planes. They create a plan to raise rocks to build pyramids. They discover the changes that occur when the angle is increased or decreased.
Curated OER
Earth's Orbit Lesson
Tenth graders devise a computational model to explore how the orbit of the Earth might change if its velocity were different. Using accurately recorded data, 10th graders defend a scientific argument.
Curated OER
Bioremediation
Students design and conduct investigations that illustrate the effect bioremediation has on organic matter and determine environmental applications. They, in groups, present their findings to the class.
Curated OER
Parabola with Horizontal Directrix
Learners find the vertex, directrix, and focus of a parabola. They graph parabolic functions and solve application problems involving parabalas.
Curated OER
Evaluating the Products of Chords of a Circle
Students investigate chords and make predictions. In this geometry lesson, students graph circles and calculate the measurement of each chord. They perform the calculations and make conjectures.
Curated OER
Understanding Cloud Formation
Pupils explore air and clouds by watching demonstration. They perform an experiment to measure air pressure changes.
Curated OER
Using an Amortization Table
Students search the Internet to find a site that contains an amortization table and make a hypothesis about the results of changing time and rate. They examine the affects of time and rate on a mortgage and discuss the difference in the...
Curated OER
Fences and Posts
Fifth graders use Geoboards to demonstrate how shapes can be made by looping the rubber bands over the nails. They make a triangle on their Geoboards. At least one side of the triangle should be either horizontal or vertical. The picture...

Linear Modeling: Functions
Students analyze linear functions. In this algebra lesson, students create a linear model to relate coordinate pairs. They evaluate and solve equations.
Curated OER
Art Dates
Students use a timeline to measure intervals and calculate the age of works of art.
Curated OER
Parametric Projectile Motion
Learners relate projectile motion to parametric equations as they identify the velocity and angle of a projectile. They create a picture on the navigator to visualize the word problem.
Curated OER
Definite Integral
Learners investigate the intervals represented by a function in this calculus lesson. They decide what interval of the function will be positive, negative or zero. They are then given graphs of functions and asked to analyze it.
Curated OER
Properties of Parabolas
Have your learners investigate parabolas. In this Algebra II lesson, students explore the basic definition of a parabola by using Cabri Jr. to create a parabola given the focus and directrix. Students interpret the equation for a...
Curated OER
Multiplying Monomials
Students differentiate between linear and quadratic functions. In this algebra lesson, students write equations of graphs and graph a function from an equation. They also identify the slope and y-intercept.
Curated OER
Quadratic Functions and Stopping Distance
Students solve quadratic equations. For this algebra lesson, students factor and graph quadratic functions. they use the properties of quadratics to calculate the distance.
