How can you relate colligative properties of solutions to everyday situations? Pupils first discuss the concepts of density, boiling and freezing points, then demonstrate how to accurately determine the boiling and freezing point of...

Here is part one of a two-part lesson in which scholars investigate the changing states of water—liquid, solid, and gas. With grand conversation and up to three demonstrations, learners make predictions about what they think will happen...

Here is part two of a two-part lesson in which scholars investigate the changing states of water—liquid, solid, and gas—and how energy from heat changes its molecules. With grand conversation, two demonstrations, and one hands-on...

Liquids, gases, and solids are the states of matter in which scholars investigate in a lesson plan that offers in-depth information and engaging activities that look into the three states and the changes their properties make when mixed...

There's a container for every matter—liquid, solid, and gas. Pupils design three different containers, each with the capability to hold one of the states of matter, and share their design with the class.     

Explore the properties of gases through one activity and two investigations in which super scientists observe the changes gas makes when encountering different conditions.

Water, one of the basic needs of humans, is found in all three states of matter on Earth; no other planet—that we know of—possesses this quality. Here is a unit that allows learners to explore through experimentation what it...

Super scientists visit ten stations to predict, observe, and draw conclusions about the physical and chemical changes that occur when different states of matter—liquid, solid, and gas—are placed under a variety of conditions. To...

Write-on! Demonstrate a writing model and support learners as they write an informational essay on a water resource issue of your (or their) choosing. The lesson plan provides a well-scaffolded summative writing...

Young scientists investigate chemical and physical changes to the states of matter—gas, liquid, and solid—as well as solutions and suspensions with a variety of demonstrations, grand conversation, and an interactive quiz to check for...

Fifth graders explore volcanoes and the rocks they produce using the Internet. The lab portion of the lesson prompts young scientists to compare and describe igneous rocks. Next, they critique a pair or more of...

Explore the Earth's different ecosystems through four lessons, an assessment, and extension activities. Lessons include informative text and step-by-step instructions to apply knowledge in interactive, and thought provoking ways; such as...

What does the ground around your home have to do with water pollution? Young ecologists learn about their local watershed and create their own cause-and-effect models of the hydrosphere.

Introduce the logic behind a dichotomous key or administer a group performance assessment with a fun and challenging classification lesson. With explicit instructions for the teacher and for collaborative groups, as well as engaging...

A critical look into the structure and function of ecosystems is here for young learners as a series of lessons and worksheet activities. Topics covered include land-based and marine ecosystems, connections to the water cycle, food...

Despite the typos and formatting issues, the Word document found here has some great potential. There are two questions that ask learners to put several events in a logical order; these could easily be made into a card sort activity....
