Consumer Product Testing
Eighth graders watch segments of CBS's Street Cents and discuss approaches used on the program. They create standards for various items and learn why they are important to have. They test different fabrics to explore clothing standards.
Curated OER
Perplexing Perimeters
In the process of constructing their own "rulers" Students develop a sense of the size of a centimeter and meter. Students select the appropriate "ruler" for the tasks. Finally, 3rd graders calculate the perimeter of objects using...
Curated OER
Area Explorations
Students explore the concept of area. In this area lesson, students find the area of irregular shapes with right angles. Students break down each irregular shape into multiple regular shapes in order to find the area. Students...
Curated OER
Fraction Facts
Students explore the concept of fractions. In this fractions lesson, students perform basic operations such as addition and subtraction with fractions. Students play a game on the computer called 'Fraction Four' that gives students...
Curated OER
Solar Speed
Learners perform unit conversion. In this algebra lesson, students calculate the distance and speed of a solar car. They graph their result as speed versus distance and analyze it.
Curated OER
Robot Ratios
Students measure the activity and parts of a robot. In this algebra lesson, students explore ratio and proportion using their classroom. They apply properties of fractions as they cross multiply to solve problems.
Curated OER
What's The Matter?
Fourth graders accurately describe various states of matter, Through experimentation, they change a variable to create a new state of matter. Students record their observations about the way matter is changed and the changes that occur...
Curated OER
What are the Odds
Students predict the-outcome of an event. In this algebra lesson, students compare and contrast the probability of an event occurring. They calculate the odds of a simple event and make estimation.
Curated OER
History of the American West
Ninth graders research early mining in California. They study the "placer method" for mining gold, which is surface mining that does not involve tunneling. They examine what it was like for the early miners to pan for gold with...
Curated OER
Surface Friction and Wear Characteristics of Common Materials
Young scholars identify the factors affecting friction. In this physics lesson, students construct their own rocket car and race them. They graph the average speeds and discuss how lubricants affect friction between rubbing surfaces.
Curated OER
Teddy Bears and Friends
Children begin by making direct comparisons between objects and putting a number of objects into order according to length. They are also introduced to measuring with multi-link cubes which allows them to compare objects which cannot be...

Social Studies: Area and Population Density
Math scholars of many ages examine the concept of population density and then discuss the significance of the population densities of Minnesota and China. They figure the population density of their school.
Curated OER
Does Sunlight Effect Leaf Size?
Learners make estimates and then measure leaves for accuracy. They calculate the area of the leaves by drawing an outline on graph paper and counting the squares. They compare the leaves exposed to sunlight to those that are in constant...
