Source Institutions
In this math lesson, learners apply the concepts of ratio and proportion to determine the length of the Statue of Liberty's torch-bearing arm.
Mercury in the Environment
Source Institutions
In this environmental science lesson, learners will examine the dangers of mercury and how humans contribute to growing mercury emissions on Earth.
Statistics: Wet Heads
Source Institutions
In this math lesson, learners learn how to construct stem and leaf plots. Learners first estimate the number of drops of water that will fit on the head of a penny.
Inverse Functions: Pennies, Pressure, Temperature, and Light
Source Institutions
The major goal of this math lesson is to have learners collect data from a variety of experiments, determine what models best fits their data, and explain why their models are best.
Linear Functions: Mystery Liquids
Source Institutions
In this math lesson, learners analyze the density of liquids in order to explore linear functions.
Polynomial and Rational Functions: Building Boxes
Source Institutions
In this math lesson, learners explore polynomial and rational function patterns.
Patterns and Relationships: Peddling Petals
Source Institutions
In this math lesson, learners use the setting of a flower-making fundraiser to explore a variety of patterns. Learners examine the patterns in a flower design made of triangles surrounding a square.
Blazing the Trail
Source Institutions
In this math lesson, learners estimate distances between landmarks and use a map and scales to determine the actual distances.
Number Sense and Computation: An Apple a Day
Source Institutions
In this math lesson, learners make estimates to analyze the number of apples per acre, and visualize the magnitude of one million.
Statistics: Steppin' Out
Source Institutions
In this math lesson, learners construct box-and-whisker plots to analyze and compare data sets. Learners investigate whether or not long-legged people run faster than short-legged people.
Multi-Variable Relations: Stressed to the Breaking Point
Source Institutions
In this math lesson, learners explore the relationship between the thickness of a spaghetti bridge, the length of the bridge, and the amount of weight that can be supported by the bridge.
Quadratic Functions: Toothpicks and Transformations
Source Institutions
In this math lesson, learners explore transformations and quadratic functions through toothpick patterns.
Exponential Models: Rhinos and M&M’s ®
Source Institutions
In this math lesson, learners model exponential decay and exponential growth using M&M's, paper folding, and African rhino population data.
Tree-mendous Plots
Source Institutions
In this math lesson, learners record and graph plant growth and interpret data. Learners plant seeds, and once the seeds sprout, record the change in height of the plants for several days.
Statistics: Creature Features
Source Institutions
In this math activity, learners collect, organize, and analyze a set of data related to types of animals in the temperate forest.
Patterns and Functions: Fill 'er Up
Source Institutions
In this math lesson, learners predict, interpret, and sketch graphs of functions related to the shapes of bottles. A measure of water is poured into a container.
Rates of Change: Bottles and Divers
Source Institutions
In this math lesson (page 2 of the PDF), learners use bottles of various shapes to explore the abstract concept of rate of change.
Up, Up, and Away
Source Institutions
In this math lesson, learners explore the real world meaning of slope. Learners conduct a balloon experiment in which they measure the circumference and flight time of deflating balloons.
Drip, Drop, Drip, Drop
Source Institutions
In this math lesson, learners design an experiment to model a leaky faucet and determine the amount of water wasted due to the leak.
Statistics: Whirlybirds
Source Institutions
In this math lesson, learners measure, predict and determine the frequency of an event as it relates to how close Whirlybirds land to a target.
