Students examine tree-ring dating and discuss the lack of water the settlers in Jamestown faced. They create paper tree rings, simulate rain patterns, and describe the history of construction paper tree sequences.

Young learners explore friction. They view a video or DVD (bibliography provided) and define terms related to friction, and work in groups to experiment with the effects of friction on speed and motion using ramps and toy cars.

Students investigate Mexican holiday celebrations and compare them to American Christmas holidays. They conduct a Mexican Christmas Scavenger Hunt. The instructional activity uses a streaming video in order to engage students in the main...

Learners model the soils layers using Oreo's. In this lesson students use their favorite food items to create a model of soil layers. A discovery lesson from a youth camp is adapted for classroom modeling and discussion of soil...

Students calculate whether or not a mole of M&M's fill their high school. They practice factor-labeling, define a mole, and calculate the number of cubic feet per mole of M&M's. To answer the question they measure and calculate...

Students study how drums produce sound by building and playing a simple drum. They measure the diameter of their can, then mark a circle two inches larger in diameter on their piece of plastic with the marker or chalk, and cut out the...

Pupils construct model landfill liners out of two-inch strips of garbage bags within resource constraints. The challenge is to construct a bag that will hold one cup of water without leaking. This represents similar challenges that...

Students investigate the characteristics of simple machines. In this simple machine lesson, students investigate work as a product of applying constant force. They answer questions about what happens on Earth and what may have happened...

Students explore magnetism. In this magnet lesson, students assemble a magnet pendulum. Students observe the pendulum noting the location of the magnetic poles as they construct the pendulum so that the free-swinging magnet comes as...

Students apply measurement techniques to create a flying object. They measure, draw, and cut out a flying wheel out of a six inch card.

Students use knowledge of area and volume to explore minimum and maximum. They create models and determine a "best" shape for getting the maximum volume or minimum area.

Fourth graders, using a map, ruler and calculator, determine the distance the pioneers traveled from Nauvoo, Ill. to the Salt Lake Valley.

Students explore area and perimeter through coordinate geometry using student literature, hands-on manipulatives, and the Internet.

Students create a scale drawing of their own homes. They use geometric formulas to find the area of each room and the total area of the home.

Learners explore the concept of estimating and organizing a group of objects into an array to count the exact number of items. They create their own arrays and practice elements of estimation.

Pupils experiment with a converging lens. They observe the image of an object through a lens. They determine the magnification of the lens.

Students complete a variety of activities using pumpkins. They visit various stations with various pumpkin activities.

Learners explore the process of inverse operations to solve square root problems. After exploring the perfect squares and area, students examine methods to find square roots by observing the teacher, taking notes, and listing vocabulary...

Sixth graders identify and use area formulas for finding the area of geometric shapes.

Students estimate quantity, length, and area. Students practice making comparison estimations of different items and estimate whether or not the amount is greater or less than a certain amount. Students practice making estimations.

Fifth graders use formulas for calculating areas of squares and rectangles to find area of complex figure, compare their own ideas with their classmates' ideas, and recognize that there are multiple methods for finding area of complex...

Students study the fractional values of Cuisenaire rods while working with favorite family recipes.

Students will construct simple curves on graph paper by connecting a series of points between the vertical and horizontal axes. They share their designs and explain the patterns.

Fifth graders create a net for a given polyhedron. They determine the corresponding polyhedron for a given net. Students investigate several polyhedra (cube, tetrahedron, and one of their choosing) and their corresponding nets. They...
