Balancing Liquid on a Coin: How Intermolecular Forces Work
Let knowledge of chemistry flow like water. Future scientists conduct two different experiments to investigate the properties of water. They learn about surface tension and cohesion as they see how many drops of water they can place on a...

Water – Changing States (Part 2)
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...

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...

Silly Stuff
It's time to get a little silly with this fun primary grade science activity. By simply combining two liquids, white glue and corn starch, a strange solid is formed, commonly known as silly putty. To ensure everything goes smoothly,...

States of Matter: Making Ice Cream
Who knew that learning about the states of matter could taste so sweet? This fun hands-on activity captures the attention of learners as they use what they know about solids, liquids, and gases to create their very own batch of ice cream.

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

Science: Identifying Properties of Matter
Students observe a demonstration of the the three forms of matter - air, water, and solids - in plastic bags. After discussing the properties, they transfer them to a Venn diagram. Finally, students identify five items in the classroom...

Density and Miscibility
The liquids did not mix — so what do density columns have to do with it? The seventh part in a series of nine provides the theoretical explanation of why density columns do not mix. The lesson covers the topics related to mixing and...

Structure-Property Relationships
High schoolers explore the structure and property changes of water through videos and classroom discussion. They are introduced to atomic arrangement of solids by looking closely at carbon in different forms, such as graphite and...

Density
Explore the concept of density within states of matter—gases, liquids, and solids—through a group experiment in which young scientists test objects' texture, color, weight, size, and ability to sink or float.

Don't Mess with Mercury (Lesson A)
Mercury is the only metal that is a liquid at room temperature. Teach your class this and many more interesting mercury facts by assigning an engaging task. A public relations activity, the exercise informs pupils of the hazards of...

Using Chemical Change to Identify an Unknown
If you discover an unknown powder, how do you determine if it is safe? Lesson uses four different tests to identify the properties of various powders that appear the same. Then scholars get an unknown powder and have to determine which...

Introduction to Matter
Begin your states of matter lessons with a demonstration designed to introduce the concept that all matter has properties. Reinforce this concept through vocabulary exploration, and the creation of atom models; salt, water, and carbon...

Physical and Chemical Properties of Matter
Students identify the physical and chemical properties of matter. They review the types of matter. Students list the four states of matter (Solid, Liquid, Gas and Plasma). They recognize and describe the different types of matter.

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...

Happy Landings: A Splash or a Splat?
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,...

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...

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...

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.

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...

What's the Matter? Where Did it Go?
Eighth graders analyze questions posted on a large poster in the room and work in groups to record their response to the question on paper, rotating to the next question after two minutes have passed. They review the characteristics of...

Activity #8 Which State Are You In?
Students define, give similarites and differences between solids, liquids, and gases. They compare and contrast a solid, liquid and gas in terms of shape, volume, compressibility, diffusion and density. Pupils classigy common...
