Students observe the production of gas as an effect of photosynthesis. In this biology lesson, students perform an experiment with pondweed and make measurements and predictions about photosynthesis and the plant.

In this desert adaptations activity, learners are given a water filled sponge which represents an animal. Students observe their "animal" for a 24 hour period and conserve the water in the sponge as best they can. They measure and record...

When measuring the circumference of a tree, does it matter how high you place the measuring tape? Most scholars have never considered this question, but scientists know that measurement techniques must be standardized. The 13th lesson in...

What better way to make predictions about future weather and climate patterns than with actual climate data from the past? Young climatologists analyze data from 400,000 to 10,000 years ago to determine if climate has changed over...

Take young mathematicians on an exploration of the world of 3-D geometry with this seven-lesson unit. After first defining the terms perimeter, area, and volume and how they apply to the real world, students continue on...

Does mass change during a chemical reaction? Demonstrate the Law of Conservation of Matter while encouraging class members to be creative with a two-part lesson. First, learners use Alka-Seltzer® tablets and water to demonstrate the...

When astronauts get hungry in outer space, they can't just call and have a pizza delivered. In order to gain an appreciation for the challenges associated with space travel, young learners are given the task of selecting,...

Take a look at acceleration within the context of automotive technology. They vary the mass on a toy car and run it down a ramp, exploring Newton's second law of motion. Though this is a classic lab activity, you will appreciate the...

Through a variety of physical and theoretical situations, learners are led through the development of some of the deepest concepts in high school mathematics. Complex numbers, the fundamental theorem of algebra and rational exponents...

Fourth graders measure one centimeter cubed blocks to determine their size. They measure lines using a worksheet that is not included in the lesson. Next, they measure the area of figures on the sheet using the cubes in place of a ruler.

Young mathematicians define population, draw convenience sample from the population, draw quota sample from the population, and draw random probability sample from the population. They explain why a random probability sample usually...

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...

A great start to activate thinking about the scientific method, instruments, measurements, accuracy, constants and laws. Each slide describes important procedures and examples essential for the study of science.

Serve up angle measurements on paper plates. Pupils use paper plates and paper-folding techniques to create a unit circle with conversions for special angles. Using their plates, learners explore the relationship between angle...

Studies show that obesity is now a global problem. But how are researchers measuring obesity? Young scientists investigate the myriad of methods for measuring body fat through a presentation. From hands-on to high-tech, viewers learn...

There is more than one way to measure an amount, as learners discover by applying multiple measurement tools in these activities. Centimeter cubes, cylinders, beakers, and measuring cups are used to find the volume of regular and...

Young scholars gather historical snow cover and temperature data from the MY NASA DATA Web site. They compare this data to data gathered using ground measurements from the ALISON Web site for Shageluk Lake. They graph both sets of data...

Students investigate unit conversion.  In this unit conversion lesson plan, students will build models of square and cubic centimeters using grid paper and generate formula tables for converting units of area and volume.  The...

Explore angle relationships associated with transversals. Pupils construct parallel lines with a transversal and find the measures of the angles formed. They figure out how the different angles are related before constructing...

Students explore the concepts of mean, median, mode, and range as they elicit data about people's favorite flavor of ice cream. A practical application of the data obtained offers an extension to the lesson plan.

How can learners use algebra to solve a geometry problem? Help learners create an equation that shows the relationship between the number of sides of a polygon and the sum of the interior angles. Students are asked to divide the...

In this college level mathematics worksheet, students solve use the Pythagorean Theorem to find the missing side of a right triangle and explore the connection between the Pythagorean Theorem and the distance formula....

Elapsed time is a skill developed by the single question that is the center of this activity. Fifth graders are asked to find out the time that is 2011 minutes after the beginning of 2011. This question addresses the standard that...

Number towers use addition or multiplication to ensure each level is equal. While this is common in factoring, it is often not used with algebraic equations. Solving these six questions relies on problem solving skills and being able to...
