Fifth graders learn how ground-level ozone is an air pollution problem. Students measure ozone levels and graph the results.

Students trace a molecule of water through the water cycle including each of its three loops. They describe why evapotranspiration demands the largest portion of total precipitation falling on a forested watershed.

Students create and analyze graphs using archived atmospheric data to compare the ozone levels of selected regions around the world.

Learners participate in an experiment to become aware of the harmful effects of an acidic solution -- acid rain.

Students estimate the size of a molecule of oleic acid. They conduct an experiment using chalk dust, water, and oleic acid, solve various calculations, and answer discussion questions.

How can you turn an ice cream activity into a scientific investigation? It's easy if you know ionic compounds, heat transfer, and the exothermic and endothermic process. Learners will explore the science behind freezing, insulation, and...

Students explore how and why local convective, possibly severe, storms develop. They examine how hailstones form and the conditions under which they form. They test mock hailstones of varying sizes to investigate the impact and damage...

In this Earth's environment worksheet, students complete a crossword puzzle given 35 clues about a variety of topics related to our Earth. Topics include ecosystems, precipitation, biomes, energy transfer, soil, weathering and rocks.

In 1897, J.J. Thomson discovered the electron, the first subatomic particle proven to exist. Scholars review their understanding of electrons, protons, and neutrons as they work through the puzzles. Each puzzle connects two or three...

A review of a full unit on energy and matter, this slide show starts with basic definitions of states of matter and their mass. It then develops the ideas of the forces that that matter can exert. Details about bonding within matter and...

Some like it hot! Scholars observe both exothermic and endothermic reactions as part of the carbon dioxide oxygen cycle. First, scientists demonstrate (or watch) a chemical reaction to create pure oxygen using fire for...

Seventh graders review graphing procedures and practice locating points using x,y coordinates. Students calculate the areas of the top and bottom surfaces of the airfoil. They construct a test model of the airfoil.

Can you imagine a pumpkin patch without pumpkins? Learners read how Tammy's family solves their problem in a cooperative way, followed by a set of 10 reading comprehension questions.

Young scholars examine and discuss urban geography and land-cover types along the Wasatch Front. They analyze thermal images, create collages, and predict surface and air temperatures from aerial photos in the Salt Lake City Valley.

Students identify the three main types of urban environments by learning characteristic land-cover types. They examine and analyze a thermal image of Salt Lake City. Then they predict surface and air temperatures from aerial photos.

Students explore the nature of the air we breathe by observing petri dishes that have accumulated particulate matter from the atmosphere. Students make mathematical calculations and inferences about the effect of this matter on...

Students design an experiment to analyze the timbre of different instruments. In this physics lesson, students analyze the missing quality in sound. They discuss their results in class.

Students organize rock samples according to their properties. In this earth science lesson, students predict whether they are igneous, metamorphic or sedimentary. They compare their prediction with the actual type.

Students determine the density of metal shot by a graphical method using significant digits in making measurements and calculations. Students graph a seris of laboratory measurements and determine density from a mass verses volume graph.

First graders complete a variety of experiments with solids, liquids and gases. They read books about matter, identify the characteristics of solids, liquids and gases and the sort and classify a variety of matter. Students make...

Sixth graders investigate how sound is made by vibrating matter. They work with a ruler and a rubber band to produce different types of vibration which makes different pitches of sound. They record their observations of the noises made...

Students explore physics by participating in a science activity in class. In this flight properties lesson, students identify Bernoulli's principle of flight and his theory of statics and motion. Students conduct a demonstration by...

Learners simulate the movement of cold and warm fronts as they listen to a story about the weather and Mr. Sun. They brainstorm the characteristics of each type of front then write about which front they would prefer if they were a...
