Balancing equations is a foundational skill for starting chemists. There are a few slides in this PowerPoint with colorful diagrams that help to explain how. Unfortunately, the presentation begins with an unrelated table of contents and...

Explore the connection of surface area to bonding within atoms. Learners complete lab investigations to model changing surface area with different sizes and concentrations of atoms. A flour fireball demonstration follows the labs to...

The questions here present situational problems and calculations to help your students understand the application of the math and data analysis practice.

In a neat and straightforward manner, this PowerPoint delivers basic introductory information on the properties of matter, physical and chemical changes, and pure substances vs. mixtures. It also defines the states of matter. For some...

When your environmental or earth science class is studying air pollution, you will want to take the time to go over this resource. Pupils peruse the history of air pollution regulations and examine outstanding diagrams of what...

An extremely thorough presentation walks new chemists through the basics of matter. There really isn't a unifying theme, however So many topics are covered: forces, elements, atomic structure, chemical properties, compounds, quarks,...

Newton's Laws get the rocket to work, but do they serve any other functions? A six-page resource classifies rockets by the type of propellant they use. It then describes applications of Newton's Laws of Motion, both in the...

Students are able to analyze practices that affect the use, availabiltiy, and management of natural resources. They are able to show that the forces of friction retards motion. Students investigate electricity and magnetism as...

Fifth graders examine both physical and chemical changes, and how to identify the difference between the two. They observe the changes that occur in butter when it is exposed to heat and cold, heat energy. In their notebooks, they write...

In this science worksheet, high schoolers are involved in questions about the events that cause and sustain fires. The chemistry of fire is the primary focus.

Students design and construct a paper rocket that can be launched with a drinking straw. They participate in a lecture and read an article about rocketry and how Newton's Third Law applies to rocket launches. Each student constructs...

In this organic compounds worksheet, students write the structural formulas for four compounds, they draw isomers for given molecules and they draw line formulas for given cycloalkanes and haloalkanes.

Students create piston systems and explore the conversion of linear to rotary motion that propels a car. In this motion lesson, students build and test a model piston/crankshift system and discover why there is a maximum limit to how...

Students explore the Chernobyl incident and the resulting environmental health impacts. They explore three different isotopes that were released into the atmosphere. Through inquiry, students determine the difference between types of...

In this gas worksheet, students find pressures, partial pressures, volumes, temperatures and number of moles of gases using the various gas laws.

Students build a model rocket. In this model rocket lesson, students explore a rocket launch cycle. Students investigate the laws of physics for each part of the launch. Students build model rockets and launch at school.

Students describe an isotope and radioactive isotope in a written essay. They describe how a specific country or region was affected by radioactive contamination and attempt to sympathize with those affected by these radioactive...

In this atom worksheet, learners read about Dalton's contributions to the structure of the atom. They answer five questions about Dalton's ideas, the law of multiple proportions and the law of definite proportions.

In this recognizing hazardous waste worksheet, students observe hazard signs, read informational passages, and unscramble the words to identify hazardous waste products. Students unscramble 4 words.

Students conduct a series of experiments on mulching. In this earth science lesson, students discuss the benefits of mulching on soil. They explore how different types of mulch affect plant growth.

In this chemistry learning exercise, students practice creating chemical equations given the names of the compounds. The answers are included in the set of sheets.
