How do you calculate your Body Mass Index, and why is this information a valuable indicator of health? Class members discover not only what BMI is and practice calculating it using the height and weight of six fictitious individuals, but...

How do you convert from one measurement to another? Pupils use unit rates to convert measurements from one unit to another in the 21st segment in a 29-part series. They convert within the same system to solve length, capacity,...

High schoolers assess human impact on water quality. They determine how the force of friction retards motion. Pupils describe and measure quantities that characterize moving objects and their interactions within a system: Time,...

Middle schoolers examine the law of conservation of momentum. In this physics instructional activity, students play marbles in order to compare the mass of the marble and velocities effects. Middle schoolers receive directions of the...

Students see the difference between weight and mass when they examine the method of measuring each of them.

Students examine the process of photosynthesis; its products and reactants, and the sequence of the process. They diagram the light reactions, record observations of plants, and discuss how difficult it is to measure plant growth as it...

Students receive bloodstain pattern evidence from a crime scene. They answer a series of questions through inquiry, observation, measurement, and analysis. Pupils complete this challenge, by reconstructing the evidence through four...

High schoolers are able to analyze gravity as an universal force. They are able to demonstrate ways that simple machines can change force. Students are able to determine how the force of friction retards motion. They are able to...

Students are introduced to basic engineering principles, road construction and material science. They explore how material properties and strength can be affected. Students become Civil Engineers by both creating Asphalt cookies and by...

Students observe the movement of pendulums, they begin to understand the relationship between gravitational forces and the mass of objects, the changes in speed and direction of objects, and the distance between objects. They understand...

Students study weather and weather measurement tools. In this weather instructional activity, students read and discuss weather myths and superstitions as well as weather terminology. Students then work in groups to complete weather...

Fifth graders define density as the amount of mass per volume a material contains, compare the densities of several types of materials, especially those that sink in water compared to those that float. They use two different methods to...

Students are able to draw a diagram of the light reactions and briefly describe what is occurring throughout the process. They are able to explain where each reactant/product in the photosynthesis equation comes from/goes during the...

Students analyze the architecture of the Red and Blue House in The Netherlands. In this architecture analysis lesson, students analyze The Schroder House and complete discussion questions. Students also complete follow up activities,...

Students examine how the circumference, diameter, and the relationship of Pi of a circle are related. They count the summer rings of a tree to determine its growth.

Second graders view milkweed plants (or pictures). The describe the plant and discuss ways some butterflies use it as a food source. Students view four pictures of different phases of a milkweed plant's life cycle. They discuss the...
