Learners construct a model of an electromagnetic spectrum using play-doh and string. They use exponents and plot the radio/microwave, infrared, and visible bandwidths of the spectrum.

Students gain an understanding of how the powers of 10 and scientific notation can be used to represent the scale of things in the universe. They relate the number of stars in the universe to the number of grains of sand on Earth's beaches.

Young scholars explore universe, and examine how big it really is and how scientists measure the distances or sizes of things by estimating sizes of different objects and reading and writing numbers in scientific notations.

The calculator has an interesting way of displaying numbers in scientific notation, but don't let that confuse your pupils! A lesson designed to give learners practice with scientific notation and calculators provides several practice...

Students observe and count bird sightings around their schoolyard throughout the school year.

Examine the concept of an electromagnetic spectrum with your students, as they observe a demonstration of a model, construct and compare a different model of the spectrum commonly used in textbooks, and construct their own models of the...

In this reaction kinetics worksheet, students draw a graph of energy vs. reaction progress and determine the factors which change the speed of a reaction. Students learn about rate laws. This worksheet has 1 graph, 15 fill in the blanks,...

Students visit a web page that gives a brief introduction to two color models and experiment with mixing different color intensities to create different colors. They visit links that give more detailed information on color.

Middle schoolers discover scales for both the solar bodies' relative sizes and their distances from the sun. They find equatorial circumference and volumes of their solar bodies. Students apply estimation strategies and proportioanl...

Students predict the number of cells after a series of cell divisions.  In this cells lesson students create a graph of their results and create a patterned drawing. 

High schoolers find the relationship between the variables based on experimental data. They determine mathematical relationship between pH and the amount of hydrogen Ions in solution.

Sixth graders are introduced to the concept of scale. As a class, they create a model of the solar system taking into account the scale between the planets and the Sun. To end the lesson, they examine "Dina the Monster Bee" and discover...

A guide to support parents as they work with their students in integer exponents and scientific notation.
