Fourth and fifth graders investigate angles and name them according to the criteria for obtuse, acute, and right angles. They examine a human-made yarn pattern on the floor of their classroom and identify angles, vertices, and types of...

Different colors of the spectrum travel at different speeds through media, causing them to refract at different angles—which allows humans to see their colors. Through a simulation, pupils see how air, water, and other media bend light....

Third graders review angle criteria and then stand. They demonstrate with their hands each type of angle called out by the teacher: right, acute, or obtuse. Music is added and students follow teacher in an angle aerobics class peppered...

Students explore geometry by using computer applications. In this spatial measurement lesson, students discuss the difference between area, weight, volume and other forms of measurement. Students utilize computer applications to find the...

Students explore Earth science by participating in a weather identification activity. In this scientific instrument lesson, students identify several weather related tools such as the weather vane, thermometer and rain gauge. Students...

Learners make fudge after reading fractional values in recipes and finding equivalent fractions to those presented in the recipes. They study measurement abbreviations.

Learners determine where to buy the heaviest earthworms as they study invertebrates. They create a double bar graph of the results of the weight data.

Students sort and compare/contrast the lengths of various whales. They sort pictures of whales in order of smallest to largest, and given a rope marked with the lengths of the whales, they compare the actual lengths of the whales.

During the Battle of Baltimore in the War of 1812, only 25% of the bombs and rockets fired at Fort McHenry actually reached their target. Using an interactive online simulation, combine your historical study with physics and...
