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...

Your physical science class learns that there are three states of matter, and that adding or removing heat can cause it to change from one state to another. By the animations, printed information, and discussion between RJ and Zoe, they...

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...

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...

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...

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.

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.

In a friendly, casual conversation on the beach, two animated teens discuss the periodic table. Assign this video to be viewed at home by physical science fans. After viewing, they can write definitions for key vocabulary terms and take...

Mix it up at a party as Sam and Zoe discuss heterogeneous and homogenous mixtures and solutions. Follow this film by allowing your class to put together individual snack foods to make their own mixture!

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...

Do solids, liquids, and gases even matter? Scholars match the state of matter to its particle picture, size and shape description, and description of the arrangement of the particles. Once they complete that activity, they complete a...

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,...

When water is a solvent in a chemical equation, we consider it an aqueous solution. Scholars match the name of four states of matter to their proper symbol in a chemical equation. Four puzzles provide repetition to help pupils remember...

In this solid, liquids and gas worksheet, students complete an on-line quiz, choosing questions and matching answers. Students score 1 point for each correct answer; a printed version is available.

Twenty-four questions about matter, the states of matter and the properties of matter make up this interactive online worksheet. Your class will determine the volume of water, the shape of water and the shapes of matter.

While scientists have identified seven states of matter, these puzzles cover the most common three. Scholars match the properties, particle motion, and particle picture to each type of matter. Three Sudoku-style puzzles review the data...

Explore the phases of water as temperature rises. Pupils consider the idea that temperature remains constant during each phase change. An interactive exercise allows your young scientists to observe the temperature and molecular...

What makes ice, water, and steam different? Their molecular arrangements are the same, but their movements are different. Individuals make this conclusion by completing the simulation activity. 

Water can travel from the highest mountain tops to the largest oceans. Using an interactive, young scientists trace the movement using an interactive online resource. They follow the water cycle by reading pop-up explanations on a...

When two liquids combine and a solid forms, the new substance is called a precipitate. Scholars test their knowledge of hydroxide precipitates and their properties. A series of four increasingly difficult puzzles challenge their logic...

In this covalent and ionic substances worksheet, students use the internet to find information about the characteristics of covalent and ionic substance and explain what causes the differences in these types of substances.

A study of the periodic table of elements doesn't have to be elementary! Deepen understanding of the building blocks of chemistry with an interactive periodic table. At first sight, the table looks like a standard reference page, but a...

In this online interactive solids, liquids, and gases worksheet, students respond to 10 multiple choice questions regarding the information included in the provided paragraphs.

Explore the water cycle in an interactive diagram of the process. The diagram shows how water is a moving system and constantly changing forms. The resourc includes vocabulary words that pupils click on in order to discover more about...
