Quadratic Formula
Young scholars explore how to solve any quadratic equation with a video about the quadratic formula. They then use the quadratic formula to solve a set of quadratic equations.
Curated OER
Rocket Angles
Eighth graders create rockets that be launched at varying angles to determine which angle is best to launch at for the longest distance.
Curated OER
Exploring Pendulums
In this exploring pendulums worksheet, students experiment with pendulums they make in the lab. They vary the length of the strings and the weights to observe the changes in the pendulum's amplitude and frequency. They answer 3 analysis...
Curated OER
Toting the Log and Lifting the Babe
Learners use simple machines that demonstrate force, friction, work and power. They investigate and explain simple machines.
Curated OER
Pen Light Lab
Students study what makes Earth warm and explore how different locations on the planetreceive different amounts of solar energy based on the intensity of the sun's rays. They calculate light intensities and compare the
amounts of light...
Curated OER
Triangulation Experiment
In this triangulation worksheet, students solve and complete 11 steps of an experiment to determine the distance to a far away object using triangulation and trigonometry. First, they select a far away object and create a baseline far...
Curated OER
The Tipping Point
Young scholars rewrite word problems and solve using math. In this word problem lesson, students gather data and observe the data. They relate this process to the scientific method and math. They review their data to be able to answer...
Curated OER
How Tall is that Tree?
Young scholars apply their math skills to develop an accurate estimate of the height of a tall tree. Three different methods are outlined. All grade levels should be able to perform the shadow method and the proportional method.
Curated OER
Similarity and Congruence
Learners determine that two figures are similar or congruent by
investigating figures that are similar and figures that are congruent. They prove that two figures are similar or congruent by using definitions,
postulates, and theorems.
Curated OER
Quilt Squared
Students study West Virginia quilts. In this mathematics lesson, students use symmetry, geometric shapes, and patterns to create their own quilt square.
Curated OER
Angles That Pair
Students identify angles. In this angles that pair instructional activity, students identify adjacent, vertical, complementary, and supplementary angles. They use straws, pretzel sticks to demonstrate given types of...
Curated OER
Oscillations
Students construct and compare the actions of various pendulums. In this pendulum motion activity, students build and test different types of pendulums. They conduct experiments with the length of the swing arm and apply mathematical...
Curated OER
Only the Shadow Knows
Students become familiar with the causes for formation of shadows. They create shadows, compare the size and shape of the shadow with the actual object, engage in shadow play theatre, and discover what happens to shadows when there is...
Curated OER
Refraction Through a Triangle
In this refraction through a triangle worksheet, students use a given diagram of light striking a triangular piece of plexiglass to determine the light ray's angle of incidence, the ray's angle of refraction, they use Snell's Law to...
Curated OER
Refraction Through a Circular Disk
In this refraction through a circular disk activity, learners are given a diagram of a circular disk of leaded glass with light striking it. Students use the diagram to find the angle of incidence of the light, the angle of refraction,...
Curated OER
Triangle Conjectures
Tenth graders investigate the theorems of ASA, AAS, AAA and ASA. For this geometry lesson, 10th graders discuss the theorems of triangles and how it is used to solve for missing sides or angles. They review how two angles are formed by...
Curated OER
Seeing Solar Storms in STEREO-I
In this geometric calculations of solar storms activity, students use a diagram indicating the location of 2 STEREO satellites, the earth and the sun to calculate the distance between a Coronal Mass Ejection and the Earth. They use...
Curated OER
Seeing Solar Storms in STEREO-II
In this solar storms worksheet, students use a diagram given the location of two STEREO spacecraft satellites, a coronal mass ejection, the sun and the Earth to solve 2 problems about the coronal mass ejection. Students use segments,...
Curated OER
Classifying Triangles Based On Properties of Angles
The interactive lesson featured here calls for the use of a Smartboard for sorting and classifying shapes. Then, pupils discuss the rules they followed for sorting their shapes, particularly focusing on the properties of angles. While...
Curated OER
Great Graphing
Young scholars collect data, use a computer spreadsheet program to create various graphs, and compare the graphs. They state the findings of each graph in writing and decide which graph type best represents the data.
Curated OER
Making a Circle Graph of a Sample Budget
Students examine a sample budget and categorize the entries as a group. Then in small groups they convert budget category totals to percents and degrees to make a circle graph related to a sample budget.
Curated OER
Graphing
Students collect data to create different types of graphs-line, pie, and bar graphs. They use StarOffice 6.0 to create graphs.
Curated OER
Educating K-12 Students about Glacier Dynamics in a Changing Climate
Students determine which of the following parameters, slope, ice, temperature or basal condition affects the glacier speed the most. They create their own experiment to test what influences glacier speed and temperature of the ice.
Curated OER
A Clasroom Study of the Life of an Airplane
Students participate in an experiment to discover the properties of lift. They work together to complete calculations and collect data. They share their results with the class.
