Finding Volume: The Water Displacement Method
We have formulas for finding the volume of geometric shapes, but what if the shape is irregular? Lesson describes how to find volume through water displacement. After a demonstration, scholars practice in small groups. Then analysis...

Density of Water
We know solids have a density we can measure, but what about liquids? Lesson explores this concept and allows scholars to explore the relationship between volume and density. Graphing and analysis questions round out the activity.

Forming a Precipitate
Can you mix two liquids to make a solid that is insoluble? Yes, you can, and pupils see this as the lesson uses more than one combination of liquids to form a solid. Through two teacher demonstrations and a hands-on activity,...

Temperature and the Rate of a Chemical Reaction
Putting glow sticks in the freezer makes them last longer, but why is that? Lesson focuses on how temperature impacts the rate of a chemical reaction. It begins with a teacher demonstration, then scholars design their own experiments...

pH and Color Change
Did you know strong bases can feel slippery and slimy? Lesson allows scholars to practice using the pH scale to identify acids and bases and their strengths. By changing the concentration of an acid and a base, they create the entire...
Science 4 Inquiry
Bubbles and Colors and Smells...Oh My!
A demonstration of elephant toothpaste hooks pupils' interest as they complete multiple experiments with colors, smells, bubbles, and more. By the end, they understand the differences between physical and chemical changes in the world...

The Cycle of Matter
An educational lesson focuses on the idea of conservation of matter through a demonstration of the water cycle, a discussion of digesting food, and the path of carbon and oxygen atoms as they change form.

Changing State: Freezing
There are five types of frost: ground frost, air frost, hoar frost, glaze, and rime. Scholars mix ice and salt in a metal container to observe frost forming on the outside of the can. Animations and videos enhance the learning.

Density: Sink and Float for Solids
Steal cubes sink, but steal ships float. Lesson explores the density of solids as well as the density of water in determining what will sink and what will float. A hands-on group activity helps pupils see that weight and volume are...

Density: Sink and Float for Liquids
We don't think of liquids as floating typically, but a quick look at any oil spill tells a different story. Lesson explores various densities of liquids and why this fact is important. After observing the density variation, scholars...

Natural Resources and Synthetic Materials
All synthetic materials began as natural materials. An engaging lesson begins with a hands-on activity and an example of the type of research that scholars perform independently. Then pupils receive a topic and begin researching the...

Energy Levels, Electrons, and Ionic Boding
Learners see how electrons are transferred in the bonding of NaCl. They then create models of NaCl using styrofoam balls and toothpicks to assist them in explaining the formation of ions and ionic bonding.

Fault Formations
The San Andreas Fault moves about two inches a year, approximately the same rate fingernails grow—crazy! The third lesson in the series allows for hands-on exploration of various fault formations. Through the use of a Popsicle stick,...

Spaghetti Fault Model
Does increasing the pressure between two moving plates provide a stabilizing force or create more destruction? The hands-on lesson plan encourages exploration of strike-split fault models. The sixth lesson plan in a 20-part series...

Eruptions and Volcano Types
The Mammoth Lakes area regularly releases warnings to hikers and skiers to be careful because melting snow releases trapped gases from volcanic vents. The 17th lesson plan in the 20-part series opens with a demonstration of carbon...
Discovery Education
Sonar & Echolocation
A well-designed, comprehensive, and attractive slide show supports direct instruction on how sonar and echolocation work. Contained within the slides are links to interactive websites and instructions for using apps on a mobile device to...

Temperature Changes in Dissolving
Alia-Seltzer tablets cause a very obvious chemical change, but do they also cause a temperature change? Each class member explores hot/cold packs, discussing how these temperature changes occur. Groups then design and carry out their own...

Measuring Dark Energy
You're only 10 minutes late? Do you know how much the universe has expanded in those 10 minutes? Scholars graph supernovae based on their redshift and see if the results verify Hubble's Law. If it does confirm it, the universe is...

Energy Flow in a Wetland Ecosystem
How is energy transferred within an ecosystem? What would happen to a food web if one of the organisms was removed? Elementary or middle school ecologists examine these questions and more in a comprehensive 5E learning cycle lesson....

Tools of the Trade
Did you know every state in the U.S. has at least one observatory? During the lesson, scholars research the cost of building and maintaining an observatory. They must present their information in a proposal to build a new observatory,...

Moon Phases and Eclipses
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...

What's in a Name?
Combine art and word analysis in a lesson about genus and species. Elementary children sleuth out the meaning of scientific names for a number of shark species using a prefix and suffix definition chart. They then draw an image of the...
