Third graders examine the phases of the moon. In this moon phase lesson, 3rd graders listen to a read aloud of The Moon Seems to Change by Franklyn M. Branley and discuss the phases of the moon. They complete a moon phase calendar and...

Students examine the evidence that scientists have used to support the existence of global warming and the greenhouse effect. How the concepts have been developed and evaluated form the focus of this lesson.

Students define temperature and heat, distinguish between temperature and heat flow, calculate amount of heat energy released or absorbed in chemical process, and design procedure, through experimentation, to gather and evaluate data to...

Learners investigate the three states of water. In this physical science lesson, students watch the video "Earth's Ecology" and observe water in its' three states. Learners record observations.

Students examine the compositions and structure of diamonds. They conduct an experiment growing crystals, watch a video, and conduct Internet research.

Third graders take note of the changes in the water level in a cup of water that is left out. Using a model of the water that depicts a lake and landscape that is being heated by a heat lamp, the students observe precipitation, and...

For this chemistry worksheet, students calculate the freezing point of a given solution. Students calculate the final temperature and state of the water in a given problem. Students solve several problems provided.

Learn about the factors that affect the way oxygen dissolves in salt water with a chemistry lab. After studying the molecular structure of water, young scientists figure out how aeration, temperature, and organic waste affect...

Teach the basics of mass spectrometry with a hands-on activity. 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...

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...

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,...

Climate models mathematically represent the interactions of the atmosphere, oceans, land, sun, surface, and ice. Part two in the series of four lessons looks at the role greenhouse gases play in keeping Earth warm and has participants...

Young scholars engage in a lesson that is about the meaning of a verb or adverb. They perform sketches with the subject matter of the words. The goal is for the actors to show the meaning of the verb or adverb with an action.

Your young environmentalists can calculate their carbon footprint and discuss ways to reduce it with a worksheet about climate change. After reading a handout about what impact one's carbon footprint can have on the environment, kids...

Learners, in teams, use given materials and their knowledge of Newton's First Law to create a device that will remove a sticky ping pong ball from a 16-oz. cup (which represents ketchup stuck in a bottle.)

A slide show serves as the backdrop for a instructional activity on the moisture in Earth's atmosphere. Through it, mini meteorologists learn about the attributes of the atmosphere and actually use data-collecting weather tools to make...

Environmental explorers examine the campus and take note of living organisms. Introduce them to the biosphere and the questions of the day: How much water can be found in the biosphere? A slide show helps you along, and even contains a...

I would weigh less on the moon? Send me there, then! On the top of the first page, a cartoon image demonstrates the difference between Earth and the moon. It then goes on to describe weight and mass and provides five practice problems...

Time to show off what they've learned! The final instructional activity in the series of six asks young scholars to process their learning from the previous lessons. They identify possible elements of the sun as well as a possible origin.

Young scholars collect snow samples around their school. They explore the concepts of density and phase change as well as the math skills of measurement and statistics. Students explore the water cycle through an interactive, down...

In this chemical reactions worksheet, students experiment with several different reactions and identify each as a single replacement, double replacement, synthesis, decomposition or combustion reaction. Students observe the changes in...

For this properties worksheet, students write the correct term in the spaces beside each definition. Then, students unscramble the letters in the boxes to answer a riddle.

Third graders explain the basic healthy eating and physical activity concepts.  In this healthy lifestyles lesson, 3rd graders describe two main components of a healthy lifestyle, demonstrate two different types of physical...
