What does stretching a balloon have to do with equilibrium? Groups explore preconditioning by stretching a balloon to a point of equilibrium. They then measure the amount of force required to stretch the balloon to the same point several...

Create a model to study a microscopic phenomenon. The seventh of 12 lessons uses an egg (without its shell) to represent a cell membrane. Using different solutions, learners explore the concept of cell diffusion. They monitor...

Create an egg-citing study of energy. Pupils investigate the effect of height and mass on the overall amount of energy of a falling object. The fourth segment in a six-part series on energy uses a weighted egg falling from different...

Let your use of the resource be in proportion to its usefulness. Pupils investigate similar triangles by measuring side lengths and considering given angle measures. The results of the investigation help develop generalizations about...

Knowing the temperature coefficient allows for the calculation of voltage output at any temperature. Groups conduct an experiment to determine the effects of temperature on the power output of a solar panel. The teams alter the...

Young astronomers learn about the Big Bang Theory and redshift through a hands-on activity in the last installment of a three-part series. Participants draw dots on balloons and then inflate them to model how galaxies moved farther apart...

Six word problems provide practice for young geometers to review angles, the angle a of straight line, circles, right angles, and others. I like the approach of these questions; they require thinking and explaining, not just computation.

How do cohesion and adhesion work together? The third installment of a nine-part series teaches young scientists the difference between adhesion and cohesion. They also learn how cohesion and adhesion work together to cause capillary...

Tired of waiting for hot water? Groups of three determine the efficiency of an electric water-heating device. They calculate the amount of energy it takes to heat the water and the theoretical amount of energy required to heat the water....

What better way to introduce the idea of a sequence than with robots! An educational activity explains the classic Fibonacci sequence before pupils build and program a robot to move. Additionally, the activity challenges individuals to...

Students find the areas of geometric shapes. In this geometry lesson students find and measure the sides, perimeters, and areas of quadrilaterals, triangles, and circles. Students relate the measures to the others by using formulas.

The students compare themselves and their shadows to various objects big and small. Students use their data to set up proportions to solve.

By using the Internet, hands-on activities, video, and cooperative learning, pupils look into the conditions in which light casts shadows on objects. The instructional activity includes fabulous hands-on activities, art projects,...

Students use hands-on activities to explore transformations. They view a video segment that demonstrate how M. C. Escher employed geometry and transformations to create so many of his famous drawings.

Coordinate planes and Cartesian graphing systems are the focus of this math lesson. Learners use video, internet activities, and engage in hands-on activities in order to explore coordinate planes. The materials needed for this lesson...

Through the use of Internet, video, and hands-on activities, youngsters learn the parts and characteristics of a circle. This fantastic lesson has some excellent website activities included in the plan. Your kids will have a much greater...

Proportions are ratios found using multiplication or division. Middle schoolers solve measurement problems, find a figure's missing dimension, and find the distance between two points. Resource features four lesson plans with detailed...

Differentiate between temperature and thermal energy. Your class will build a thermometer using simple materials and develop their own scale for measuring temperature. Discuss with your class and consider why engineers need to understand...

Upper graders examine the concept of probability. They collect data and create a bar graph. They must interpret the data as well. Everyone engages in hands-on games and activities which lead them to predict possible outcomes for a...

Few topics engage young mathematicians as much as learning about money. Through a series of shared readings and hands-on activities, children explore the US currency system, learning how to count money and calculate change as they create...

Students study the concepts of weight and drag while making paper helicopters. They measure how adding more weight to the helicopter changes the time for the helicopter to fall to the ground. They apply what they examine to the work of...

Students explore the concept of measuring length using a one-inch pipe cleaner "inchworm." They listen to the story "Inch By Inch by Leo Lionni and discuss how the animals were measured by the inchworm in the book. In pairs students...

After reading an interesting account of how the X-1 aircraft was designed, built, and utilized, young engineers try their hand at constructing a paper glider version of the airplane. They cut out the plane out of a nicely designed...
