Students investigate how salt affects the state of ice. In this ice cream making lesson, students change the freezing temperature by adding salt and observing the results. Students use experimentation and comparison to see how chemicals...

Eighth graders study the conservation of matter.  In this chemical reaction lesson students examine what happens during a chemical reaction and complete a lab activity. 

Students explore the three main forms of matter: solid, liquid, and gas. They examine concrete examples of each, using their five senses and "experimenting" to find differences in them. They find pictures of each, cut them out and past...

Students observe physical change of melting by observing substance in original state, melting substance, allowing substance to return to original temperature, determining if substance retained its original properties, and recording results.

How can you see a number in nature? Here, learners discover both Fibonacci numbers and the golden ratio by exploring a number of different resources.  Note: Some of the resources are older and may be missing some of the links, but...

Introduce your class to one of the ways that technology is benefiting humanity. The Global Precipitation Measurement Mission involves the data collected by nine satellites from different countries with a united focus on studying world...

First graders understand that gases take up space even though you can't see or smell it. This is done through many experiments like trapping air in different sized bags, using balloons and plastic bottles, and blowing bubbles. They...

Learners participate in a series of demonstrations about Bernoulli's principle. They explain how air pressure varies with air speed. They write a detailed lab report about the activity. This is a great way to explore this concept.

Determining whether or not something is living can be more difficult than it seems. Put your young scientists to work defining their own criteria to identify life, then work with three samples to see if they are alive or...

First graders create ice cream in class.  For this matter lesson, 1st graders discover solids, liquids and gases and the properties of each.  Students produce a batch of ice cream in class using household items.

What does it take to be considered a smart material? Learners investigate the properties of Nitinol, a smart material, through a hands-on lab activity. They examine the crystal lattice structure and the conditions required for Nitinol to...

Students make Moebius strips and use them to demonstrate the interconnectedness of an environment. They explore the natural cycles (water, oxygen/carbon dioxide, carbon, nitrogen) within the environment. They describe how the cycles are...

Young scholars examine the definitions and characteristics of plasma. After reading an article, they analyze new technologies to study plasma. In groups, they create a poster on how the different types of plasma work and write letters to...

An incredibly colorful PowerPoint presents all the facts and definitions about waves that you could need for beginning physical scientists. There are several useful links to online animations of wave action. This may have been produced...

Young scholars observe crystals and their shapes and formation. In this crystal formation lesson, the teacher prepares crystal gardens for the students to observe, then the class finds examples of crystals in nature and observe a teacher...

Students engage in a lesson that is concerned with the concept of water chemistry. They conduct research using a variety of resources. Students also consider an experiment to observe how water has the abiility to exist as three different...

Students conduct experiments to learn about sound wave vibrations in objects and pitch. Students test how varying the volume of water in a vessel changes frequency and pitch.

Learners study the liquid and solid states of water. In this water states lesson, students complete three experiments to study water as it cycles from a liquid state to a solid state and back. Learners finish with a Venn Diagram...

Students name and locate countries where radiation from the Chernobyl accident traveled, describe how air pollution travels from one area to another and list the travel of radiation in chronological order.

Students conduct an experiment. In this forms of water lesson plan, students observe ice to see what changes take place and then write in their journal about what they observed.

Students examine the path of pollution that was created by the Chernobyl accident. They discover how air pollution travels from one area to another and sequentially locate the countries where radiation traveled to.

Young scholars explore the surface area to volume ratio in cellular respiration. While participating in an interactive lab experiment, they examine proportional surface area and discuss nanotechnology. Students observe the...

In this change of state quiz activity, students complete an on-line quiz, clicking on questions and matching answers, scoring 1 point for each correct answer. A printed version is available.

In this nuclear chemistry worksheet, students determine the biological effects and the applications of nuclear chemistry. Then students use Einstein's theory of special relativity to complete 3 problems.
