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...

The Density of Liquids and Solids
There are underwater rivers that flow on the ocean floor thanks to a difference in density. Scholars learn about the density in both liquids and solids in the second lesson of an 11-part series. They then determine the density of water,...

What’s Up with Matter?
Take a "conservative" approach to planning your next unit on mass and matter! What better way to answer "But where did the gas go?" than with a lab designed to promote good report writing, research skills, and detailed observation. The...

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.

Floaters and Sinkers
Whatever floats your boat. Young engineers learn about density by measuring the masses and volumes of boxes filled with different materials. Using their knowledge of densities, they hypothesize whether objects with given densities will...

A Matter of Fact
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...

Measuring: Why Can't We All Just Get Along?
Students examine why having standardized units of measurement is important. They investigate the use of non-standard measure, twigs, while measuring the piece of tape. Next, they experiment with straws, paper clips, and rulers before...

Gases Matter
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...

States of Matter
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 takes to...

Activity #6 'Nothing' Matters: A Demonstration
Students observe the 'pouring' of a gas. They compare the masses (weights) and densities of two gases. Pupils define the following terms: matter, mass, and density. Students answer questions after watching the demonstration.

Activity #19 The Density of Alka Seltzer Gas
Middle schoolers (teachers) complete the activity, they should not come in contact with Alka-Seltzer. They comprehend that the density of a gas can be calculated from its mass and volume. Pupils calculate the volume of gas generated by...

Buoyancy
Swimmers know to float by turning their bodies horizontally rather than vertically, but why does that make a difference? In an interesting lesson, scholars explore buoyancy and the properties of air and water. They test cups to see which...

Matter
Young scholars complete a unit of activities to learn about states of matter and how to measure matter. In this matter lesson, students complete 8 lessons to learn about matter, its states, and how to measure matter.

Christa's Lost Lesson: Effervescence
How are chemical reactions affected by gravity? Learners explore the phenomenon of effervescence as part of the Christa's Lost Lessons series. They compare findings in an experiment on effervescence to a video of a similar experiment in...

Asphalt Lab
Students are introduced to basic engineering principles, road construction and material science. They explore how material properties and strength can be affected. Students become Civil Engineers by both creating Asphalt cookies and by...

The Grouchy Ladybug
Students complete a Cirlce Map about time. They recall times during the grouchy ladybugs travels, and add dots on ladybugs using turn-around facts. Pupils correctly sequence the events of The Grouchy Ladybug. Students compose new...
