Archimedes' principle is practiced as chemistry learners practice computing the density of different gases, liquids, and solids. Using a chart of standard densities, they also identify unknown materials by similar calculations. Fifteen...

This PowerPoint is a gem! Seventy-eight slides present an entire introduction to matter in bullet-point fashion. Viewers learn about everything from mass and inertia to phase changes and gas laws! The only glitch is that the links to...

Dare your class to drive dissolved carbon dioxide out of carbonated liquid at different temperatures to discover if there is a difference in rate. To make this experiment more sound, have explorers use equally measured amounts of soda...

Sugar crystal growth is observed as an example of physical change and cabbage juice pH indicator is used to demonstrate chemical change. The crystal growth is tracked over five days. The cabbage juice experiment is involved and can also...

Characteristics of each state of matter are listed, the formulas for heating water are detailed, and values for boiling and heat of vaporization are presented. This simple slide show provides direct instruction as well as practice...

Small groups place sand and ice in a covered box, place the box in the sunlight, then observe as evaporation, condensation, and precipitation occur. These models serve as miniature water cycles and demonstrations of the three phases of...

Third graders define matter as anything that takes up space and has mass, recognize, through experimentation and observation, that matter exists in three forms, including solid, liquid, and gas, and discuss characteristics of each form...

Students explore the states of matter. They discuss the different phrases of matter and categorize everyday substances as solids, liquids, or gases. Students explore the relationship between the phases on an atomic level and the role of...

Pupils observe a teacher demonstration o classifying matter by its physical properties of shape and size. After discussing the definition of matter, students describe the state of matter. They sing a song to the tune of "Bingo." In...

By viewing this PowerPoint your students' understanding of molecular energy should increase. The properties and inter-particular forces are summarized. The logical progression of information is useful, but more data to demonstrate...

Students explore the three states of matter. In this matter lesson, students are shown a variety of examples and decide whether it is a liquid, solid or gas. Students brainstorm what characteristics the objects in each group share.

Students analyze earth science by creating a frozen treat in class. In this heat transfer instructional activity, students discuss how matter is transformed from solid to liquid and liquid to gas when energy is removed from the equation....

Advanced techniques for the lab use of chromatography are detailed here and your students will learn the specifics of separating molecules using a staionary and mobile medium. Diagrams of the equipment used and some facts about how...

Young scientists learn that seeing isn't necessarily believing when it comes to the states of matter. After performing a fun class demonstration that models the difference between solids, liquids, and gases, children complete a series of...

Young scholars study soil and how particle and pore size affect water movement.  In this soil lesson students complete a lab activity to investigate pore saturation and sponge like behavior. 

Do solids, liquids, and gases even matter? The presentation focuses on changes in matter, including phases, Boyle's Law, Charles' Law, and physical changes. 

First graders are read a story about the various stages of matter with a focus on gases. Using a ziploc bag, they capture as much air as possible and discuss how it takes up space even though it is invisible. To end the lesson, they blow...

Little chemists address whether or not you can get sugar back out of tea after it has dissolved. The PowerPoint itself simply walks them through the questioning process, considering different possibilities. The final slide settles on...

There are three basic states of matter: Solid, liquid, and gas. Help your learners with visual impairments to understand the chemical nature of each state of matter with tactile elements. Marbles are used to model the particles in each...

The question is posed, is it permeable or impermeable, it's up to your critical thinkers to determine the answer. This presentation provides several scientific concepts related to permeability and the properties of matter alongside...

After listening to a story about the water cycle, learners create their own versions of this tale. This is a great way to have your class review the concepts of evaporation, condensation, precipitation, and runoff.

Here is a great way to get pupils to express a scientific concept in a fun way. After hearing the story of Walter the Water drop and learning facts about the water cycle, the class will write a creative expository piece describing what...

First graders explore the properties of matter. For this states of matter lesson, 1st graders conduct scientific investigations that require them to mix, cool, and heat objects in order to observe changes in the properties of matter.

In this liquids and gases instructional activity, students review 9 vocabulary terms associated with liquids and gases by completing a crossword puzzle.
