Students complete all of the steps in the scientific inquiry process to study Earth's energy cycle; most specifically temperature and the effects of albedo (energy reflected back from Earth's surface) on temperature.

Students participate in a lesson that looks at the potential for energy from sunlight. Students conduct research from a variety of resources and construct an object that is used to measure the energy of sunlight and calculate the amounts...

Second graders distinguish the different phases of the moon. In this astronomy lesson, 2nd graders study the history of its discovery and myths about its origin. They simulate how the moon's surface is illuminated by the sun.

Students create and observe coacervates. In this origin of life instructional activity, students create coacervates by mixing carbohydrate and protein solutions. They observe the life-like qualities of the structures and discuss the...

Students examine the topics of ocean waves, currents, and tides. They locate and label ocean currents on a world map, conduct experiments, analyze key vocabulary, view demonstrations and record the data, and complete handouts.

Students review an interpretation of geologic history and relate it to the formation of oil deposits. They explore and explain factors controlling the porosity and permeability of sediments and sedimentary rocks. Pupils also interpret...

Students discover the different forms of water on Earth. In this states of water instructional activity, students read material on the different forms of water and how they are created. The students answer written questions on worksheets.

Students explore the Solar System. In this cross-curriculum space instructional activity, students identify the planets, name them in order according to distance from the sun, and describe major characteristics of each planet. Students...

Students examine the new categories of planets and how planets were reclassified.  In this solar system lesson students complete activities using Venn diagrams and images of planets. 

Study and compare multiple aspects of both Aztec and Inca civilizations. Young historians explain how each of the empires came to be, and how they were both defeated by the Spanish. The resource starts out as a good lesson, but is...

In this theory of evolution instructional activity, students will review the role Charles Darwin played in the theory of evolution, natural selection, and adaptations. Students will explore some of the different types of evidence for the...

Young geologists begin exploring volcanoes of different structures and states: active, extinct, or dormant. During the lab, they make three models and compare different types of volcanoes, including composite, cinder cone, and...

Learn about damage associated with earthquakes and materials that best withstand a quake. A lab engages class members in the experimental design and construction of sturdy structures that can endure various earthquake...

Earth's magnetic poles switch positions about every 200,000—300,000 years. In the activity, groups create a planet with a magnetic field. Once made, they use a magnetometer to determine the orientation of the planet's magnetic field....

One way to identify possible volcanic activity on other planets is by testing the planet for magnetism. A science lesson begins with pupils constructing their own planet from a dead battery, magnets, paper, and tape before labeling...

Here is an activity that merges technology with life skills as individuals use Google Earth to explore the differences between coordinate systems and map projections. The self-guided learning exercise is the fourth segment in a nine-part...

Teach the basics of mass spectrometry with a hands-on lesson. The fourth in a series of six lessons explores how mass spectrometry measures the ionic composition of an element. Learners then compare and contrast relative abundance and...

Starry-eyed astronomers draw different views of the Moon in order to introduce its phases. Then they experiment with a ball and a lamp to recreate the phases. A demonstration ensures every pupil understands the process, and the...

Neptune takes 164.8 Earth years to travel around the sun. In the fifth of 22 lessons, young scientists create a travel guide to a planet in our solar system. They provide tips for others on what to bring, what they see, and their...

Huygens spacecraft landed on Saturn's moon Titan in 2005, making it the farthest landing from Earth ever made by a spacecraft. In this hands-on activity, the 12th installment of 22, groups explore how density affects speed. To do this,...

Explore the concept of evolution and cell biology; your class can work in groups to use the internet to view websites on evolution, take a quiz, and complete a lab activity.

Expectant earth scientists examine the bottom side of a leaf and learn the role of the stomata. They consider the gas exchange that occurs through these structures and relate how the climate is changing to its impact on food crops. This...

When van Leeuwenhoek saw cells and single-celled organisms for the first time, he knew these small things were a big deal! Share his discoveries with young learners through a narrated video, model-building activity, and scale study....

By measuring the wavelength, frequency, and intensity of electromagnetic radiation, scientists determine the temperature, density, and composition of far away items. Scholars rotate through ten lab stations using a spectroscope at each...
