Students complete a variety of labs to help them explain how energy affects the changes in states of matter. They also be required to collect and record data, graph data, and apply interpretations of that data.

Second graders discover volcanoes that occur around the world. They identifying volcano parts.

Young scholars study science. In this efficiency lesson, students explore different forms of energy and compare them to determine which works the best. They work independently to create a collage of different energy sources (using...

How is it possible for ocean water to have layers? The sixth installment of a 23-part NOAA Enrichment in Marine sciences and Oceanography (NEMO) program investigates factors that cause different water densities to occur. Experiments...

Change the density of water by adding minerals. The presentation discusses density—from the definition to calculations—and applies it to the real world. It briefly mentions specific gravity, and finishes by showing Archimedes'...

Students read and discuss an article about carbon dating, then participate in a hands-on lab to discover how carbon dating works. Students also write a letter to a friend explaining the process, and how archeologists use the process to...

Eighth graders explore the chemical and physical properties of a variety of elements in a lab setting. They organize the data they collect onto a spreadsheet and then choose one element from the periodic table to research. They...

Students explore why the oceans do not freeze. They explain why they think the Atlantic Ocean does not freeze. Students are given background information about what they are doing. They create a hypothesis about what they believe...

Students examine molecules and the changes in energy of a system.  For this energy systems lesson students complete a lab activity and describe changes of state.

Fourth graders explore whether the making of homemade ice cream is a physical change or a chemical change in a lab experiment. Students identify states of matter, describe the physical properties of states, and collect temperature data...

Students examine icebergs and how they are suspended in water, why ice floats, the melting process of an iceberg, and the floating behavior of ice compared to that of a cork through a lab activity.

Students describe four states of matter and their characteristics, explain thermal expansion of matter, interpret state changes in terms of kinetic theory of matter, explain relationship between temperature and volume of a gas, state...

Students identify auxins from their structural formulas. They understand the process of refluxing in chemical synthesis. Students perform thin layer chromatography using silica gel plates to differentiate chemical substances.

Students synthesize Indole-3-Acetic acid from 3-indolylacetonitrile. In this biochemistry lesson, students determine the effect of different concentrations of IAA on lima beans. They explain how hormones help in plant development.

Fifth graders watch a demonstration in which a balloon is inflated using the gas created by combining vinegar and baking soda. Then, in groups, they combine various assigned substances and watch and record the results.

Prepare your class for a quiz with these physical science review questions. Learners respond to 7 questions about ionic and covalent bonds, oxidation states, and chemical and physical changes. In addition, they name compounds and balance...

Ninth graders participate in classroom discussions, demonstrations and hands-on laboratory activities about pure substances and mixtures with a focus on common household materials. They investigate: What is a pure substance? What is a...

Students participate in experiments to visualize the differences between chemical and physical changes. They attempt to detect the five characteristics of a chemical change.

Young scholars experiment with Thin Layer Chromatography to separate pigments found in flower petals.

Eighth graders, in groups, explain the difference between physical and chemical changes.

Students experience and practice compositing and recycling through hands-on-activities. They distinguish between which items from their trash can be recycled, composted and reused. The process for making recycled paper is also covered in...

A page from the University of Maryland Physics Lecture Demonstration Facility. Provides directions for a teacher demonstration of the effect of an ionic solute upon the freezing point of water. Shows apparatus and set-up; provides...

This online resource is for information on the 16th element of the Periodic Table--Sulfur--can be found here. The site lists scientific information such as atomic weight, atomic number, melting/boiling point, and more. There is also a...

A page from the University of Maryland Physics Lecture Demonstration Facility. Provides directions for a teacher demonstration on the phenomenon of regelation. Shows apparatus and set-up; provides suggestions. Easily adaptable as a...
