Time to show what they know! Module five in a 14-part series about solids, liquids, and gases redirects to an interactive quiz. Learners test their skills on topics such as states of matter, phase changes, and Brownian Motion. With...

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...

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.     

Who knew that learning about the states of matter could taste so sweet? This fun hands-on lesson 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.

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.    

Need a solid resource for teaching about states of matter? Science scholars go with the flow in a simple interactive that shows how intermolecular attractions determine a substance's phase. Pupils take control of the level of attraction...

Quiz time! Part eight in a 14-part series about solids, liquids, and gases provides an opportunity to assess individual's learning. The interactive quiz covers the topics of solubility, solubility curves, and diffusion.

There's more to melting than meets the eye! Junior physical chemists investigate the differences between specific and latent heats as a substance undergoes a phase change. Users remove heat from the system and observe changes in kinetic...

Why are solids, well ... solid? Take a peek inside a solid substance with an easy-to-use interactive. Science sleuths examine the motion and position of the atoms that make up a solid before drawing conclusions from their observations.

What happens inside a melting solid? Prospective physical chemists observe a solid-to-liquid phase change at the molecular level using an inspired interactive. Pupils add heat to a close system, then monitor changes in kinetic and...

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...

Young scientists get to the heart of the matter as they complete this learning exercise on the properties of solids, liquids, and gases.

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...

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...

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....

Blow the minds of young scientists with this collection of inquiry-based investigations. Based on a series of eight videos, these "hands-on, minds-on" science lessons engage young learners in exploring a wide range of topics...

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

Energize your phase change lesson plans! Add a short but focused interactive into the mix and watch as pupils experience how states of matter react to changes in kinetic energy. The resource tracks the kinetic energy of a cold solid...

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. 

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

Learn about radiation, convection, and conduction with a multiple choice learning exercise. Each question prompts kids to decide what is different about each form of heat energy transfer, and what is the same.

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...

Whether you're using a collection of Dr. Seuss books to teach basic math skills like counting, adding, and subtracting, or exploring the different states of matter by melting a crayon with a hairdryer, a series...

What's the solution to gaining insight into your class' progress? Give this brief quiz a try! Part 10 of a 14-installment series on states of matter tests learners' skills in the areas of dilution and the properties of water,...
