Greatest Common Factor: Using the Factor Tree
Students find the greatest common factor of two numbers. For this algebra lesson, students use prime factorization to find their factor to simplify equations. they create a factor tree to find the factors of composite numbers.
Curated OER
Abiotic and Biotic Factors
Students examine abiotic and biotic factors. They define biotic and abiotic, categorize a list of items onto a Venn diagram, label various items from areas on the school grounds as biotic or abiotic, and diagram a magazine picture.

Super Size It, Please!
Pupils take photos from a given distance and determine the height of the person using a scale factor. Pupils calculate the ratio of student actual height to student photo height. They take pictures from 3 different distances to see if...

Extraordinary Extrapolation
Learners study how scientists have estimated the maximum height to which trees can grow, and assess the reliability of interpolation and extrapolation techniques by making predictions with particular data sets and analyzing accuracy of...

The Fair Factor
Young scholars participate in playing many games to determine if they are fair or not. They create their own game that is fair to play with their classmates.

How Healthy is the Wetland?
Students explore wetlands. In this ecology lesson, students visit a wetland site and collect data about the wetland functions. Students record their results and use the data recorded to rate the wetland site on its function.
Curated OER
Plant Diversity and Distribution
Students construct a defined plot on school grounds and observed patterns in plant life. They count trees, shrubs, cacti and record on a data sheet. They compare data and generate a plant diversity overlook for their school.
Curated OER
Similar Triangles - Applied Problems
Students differentiate between similar and congruent triangles. In this geometry lesson, students identify the angles of triangles using the similarity theorem. They apply concepts of triangles to the real world.
Curated OER
Maximizing Lumber Cuts
Students examine how lumber companies use each tree to the fullest extent. They practice using a saw blade in which they cut a piece of wood in different configurations to see which cut can waste the least.
Curated OER
What's in Wetland Soil?
Students examine the organic and inorganic components of soil. In this environmental science lesson plan, students identify the factors that influence soil formation. They collect soil samples, conduct tests, and analyze the results.
