Students describe how wedge and lever makes work easier. In this physics instructional activity, students analyze experimental data by creating a graph to see the trends. They calculate the work done and mechanical advantage of these...

Students view an applet to study the phases of the Moon in relation to the orientation of the sun, moon, and Earth.

Middle schoolers examine the health condition of jet lag. Using mealworms, they test the effect of light on the development of them into adults. They answer discussion questions and examine the relationship of age and one's activity...

Students research the Earth's patterns of rotation and revolution, create a chart and graph of these patterns and use them to explain the causes of night and day and summer and winter.

Students examine how the processes of condensation and evaporation occur. They describe the relationship between heat energy, evaporation and condensation of water on Earth. They give examples of the processes of evaporation and...

First graders use senses to examine objective or events, then gather and interpret data with instruments. They design invention to support or refute hypothesis, then generate, record, and organize data. They improve environmental...

Third graders read books about the moon and discuss its perceived changes as it moves across the sky. They observe the moon over the course of a month and chart their observations. They discuss their observations and conduct further...

Students use computer images to explain why the Earth has seasons and examine the phases of the moon. They create 3-D images and present them to the class. They answer a series of questions at the end of the lesson.

Students investigate rocks. In this earth science activity, students collect rocks from the schoolyard and describe each of the rocks. Students measure and weigh each rock and record the results. Students create a rock guide for the...

In this space science worksheet, middle schoolers complete each of the statements with the correct word or phrase about the moon. Then they identify four ways that scientists believe the moon was formed, selecting one and writing a...

Third graders learn how to use solar power.  For this sun, technology and energy lesson, 3rd graders learn how the solar power from the sun can give off energy, learn about solar panels, discuss their uses and benefits, and design a...

Third graders read, write, and listen to information about the sun and its effects on the Earth.as it relates to its axis, orbit, rotate, and revolution.  In this solar system lesson, 3rd graders examine how the sun...

Leaf structure and its specializations for photo-respiration are detailed here.  Slides provide information about Photo-respiration biochemistry and its impact.  A class learning about classic respiration will appreciate the...

Students participate in a simulation in which they discover the threats to sea turtles throughout the world. In groups, they act out the life cycle of a sea turtle and describe the stresses that threaten their survival. As a class,...

Students explore the earth's atmosphere, weather, and climate. They begin class with a discussion about weather patterns, atmosphere, and the layers of the earth. After the class discussion, students rotate through four stations to...

Students experience and participate in a journey through a "Voyage" exhibition of the Solar System and the frontier it covers. They build a dynamic model of the Earth and Sun. Descriptions are given on the relative sizes of the Sun and...

First graders discuss the book The Lorax and research what living things need. In this environmental lesson, 1st graders investigate how humans affect the growth of plants. Students conduct an experiment with sunflowers.
