Students discover how engineers use sound energy. They participate in hands-on activities in which they discover how we know sound exists. They identify different pitches and frequencies as well.

Students work together to test how the color of a material affects how much heat it absorbs. They make predictions and take notes on their observations. They discover how engineers use this type of information.

Young scholars work together to identify the accuracy of sundials. They track the position of the sun and create a shadow plot. They discover the difference between real time and clock time.

Middle schoolers investigate water vapor. They view and analyze photos, conduct Internet research, and analyze the total water vapor/total liquid water data plot.

Students investigate local surface weather conditions. They log weather conditions for thirty days, develop a graph, plot cloud cover, and compare/contrast the graphed lines of various weather factors.

Students investigate the concept of lab safety using a variety of different activities. The equipment necessary is covered. They draw the different types of lab tools using a graphic organizer.

Young scholars practice and perform the song "B is for Banana" using their knowledge of basic rhythms in 4/4 and student-created rhythm accompaniment based on speech. This excellent lesson is provided by the MENC (National Association...

Students create movement, improvise rhythmic accompaniment, practice, and perform the song "Phytochemicals" in this excellent elementary-level General Music lesson. The lesson includes lesson challenges for more advanced students.

Students compose, notate, and evaluate their own rhythmic compositions using the song "Broccoli" for inspiration in this excellent elementary-level General Music lesson. Emphasis is placed upon four-measure patterns and the classic...

Young scholars discover how salt water makes a pencil float better than freshwater by measuring and comparing the lengths of the portion of the pencil that floats above the water surface. They then determine if an unknown water sample...

Fourth graders rank balls by size from smallest to largest and from lightest to heaviest and then by how much they made the water rise. They then discuss why certain balls make the water rise higher than do other balls.

Students observ the cooling and warming of room temperature, hot, and ice cold cans of water by measuring the change in temperature over time. They then attempt to develop explanations for the observations made and apply their findings...

Students role several balls of different weights down a ramp and into a paper cup and record how far each ball made the paper cup move. They then answer questions that help them analyze their results and reinforce the idea that energy...

Students investigate the motion of a swinging pendulum. They experiment with a pendulum to find out why it might swing at different speeds at different times.

Students observe that colored markers are a mixture of many different colors by performing a chromatography experiment. They make observations, record information, and make generalized inferences from their observations.

Learners observe the motion of both a pendulum and a spring pendulum . They then explain the differences and the similarities between the two types of motions.

Students compare the price and quality of different kinds of plastic kitchen wraps and then rank them from best to worst. They take into account how well it comes out of the roll, if it seals well, it is tangles, how much weight it...

Students examine the properties of a liquid that contains water and food coloring and a liquid that contains water, food coloring and a liquid detergent. They interpret their data, describe properties, and make reasonable explanations...

Learners listen to Chapter I, Chapter II, Chapter III, and Chapter IV of "The Forgetful Pony". They observe different stages of development of mealworms. The student sequences pictures to show the life cycle and draws the developmental...

Fifth graders work in teams of four to measure the rebound heights of a tennis ball dropped from four different heights. They investigate with the bouncing balls to measure changes in the type of energy they possess.

Students study and analyze data collected on the relationship between the snowshoe hare and lynx in Canada over a 28 year period and create a graph. Students also write a response to a proposal to reduce the lynx population.

Students collect data on the cooling of water in two different test tubes, one that is wrapped in wet newspaper and one in dry newspaper. They then relate this cooling effect to the body's perspiration.

High schoolers measure and graph the absorbance of light by chlorophyll at a specific wavelength versus chlorophyll concentration. They are given an unknown and determine its concentration from their calibration curve. Students become...

Students become familiar with the concept of spectroscopy or the study of the interaction of matter with electromagnetic radiation. They prepare solutions and measure absorbance at different wavelengths. Pupils comprehend that mater and...
