Young scholars participate in a lab activity using three tuning forks of different frequencies and a Resonance Tube Set purchased from Sargent-Welch to take measurements of resonant lengths of the tuning fork frequencies. Students then...

For this isotopes, molecular notation, and electron orbits worksheet, students read selections pertaining to isotopes, mass number, molecular notation, electric attraction, and electron orbits. In addition, students complete 11 short...

In this elements learning exercise, students determine the atomic number, mass, number, electrons, protons, and neutrons for elements. Students review the electromagnetic spectrum. This learning exercise has 1 graphic organizer and 13...

In this isotopes worksheet, students review mass number, molecular notation, electron attraction, and electron orbits. This worksheet has 5 matching and 5 short answer questions.

For this speed of light worksheet, students read about Danish Astronomer ole Roemer and his discovery of the speed of light. Students complete 4 short answer questions based on the reading.

Students examine the water cycle. For this hydrologic cycle lesson, students follow the provided procedures to demonstrate the how water moves around the planet through the dynamics of the water cycle.

Third graders consider outer space. In this introductory solar system lesson, 3rd graders complete a KWL chart and listen to the story The Magic School Bus: Lost in the Solar System, by Joanna Cole & Bruce Degen. They will contribute...

Pupils explain the stages of the plant growth cycle, and create a slide show to chart the stages of growth.

Students explore the uses of optical fibers, are exposed to the principles of refraction and total internal reflection, solve problems relating to the design of fiber optic cables, and compare them to copper transmission lines.

Second graders read "The Cloud Book" by Tomie dePaola to jumpstart their cloud study. They offer examples of liquids, solids, and gases and chart them. They observe the making of a cloud in a demonstration. They discuss and draw...

Students explore what happens to light intensity as depth increases using a light intensity logger. They construct a PVC model to hold water and identify what factors could influence the amount of light attenuation.

Students comprehend the physical properties of pressure and Boyle's Law by designing a depth gauge. They construct a capillary depth gauge and calculate the calibrated depth marks of the capillary tube. They determine the margin of error...

Students explain that when forces on an object are balanced, the motion of object does not change. They describe how an object changes its motion when forces on it are unbalanced. They plan and conduct a scientific investigation to test...

Young scholars identify the variables involved in the motion of a pendulum. In groups, they research how each different variable is related to the energy the pendulum produces. They share their results with the class and compare them...

Students listen as the teacher introduces Newton's early discovery of the diffraction of light. They use multiple sources of light (fluorescent, incandescent, sunlight, etc) to bend the light. They first use a prism then a diffraction...

Students study ponds and wetland ecosystems and examine the food chains and webs in them.  In this aquatic ecosystems lesson students answer questions about the diversity of the flora and fauna in a pond.
