Falling objects can be brutal if you don't protect your noodle! Scholars explore the motion of falling objects through measuring short intervals to determine if the distance traveled varies with time. Building off of this, scholars...

In this chemical change worksheet, learners conduct 4 experiments set up around the room. They follow the instructions at each station for each experiment and list the physical properties and observe any changes at each station. Students...

Moving from its definition to how it moves and its different types, scholars see different examples and then move into its application and use in everyday lives, in an energy-based presentation.   

Students determine crude oil can be separated into useful fractions by a process of fractional distillation. They write a balanced equation for the reaction between a hydrocarbon and oxygen.

Students make spinners to investigate rotational inertia, rotational speed, angular momentum, and velocity. They make two sets of spinners that have different mass distributions and shapes. They complete a worksheet while experimenting...

In this stoichiometry worksheet, students interpret a chemical equation, determine number of moles produced or mass of product, and solve for the limiting reactant for reactions. This worksheet has 25 problems to solve.

Laughter may be the best medicine, but aspirin is also important. Young chemists analyze aspirin tablets using titration in this lab experiment. They then repeat the entire experiment using a different aspirin brand. 

Students investigate an accident and relate it to math. In this trigonometry lesson, students measure the accident scene, the friction produced, and the speed from the skid marks. They create a poster of their findings.

Students study polyatomic ions and write binary and ternary ionic chemical formulas. They explore putting together different monatomic ions and coming up with as many chemical formulas as possible. They play a game similar to memory...

Young scholars study reaction rates, what determines how fast a reaction happens and how the chemical changes occur.  For this reactions lesson students complete a lab where they use Alka-Seltzer to observe reaction rate and create...

Middle schoolers explore the concepts of potential and kinetic energy by bouncing assorted balls on different surfaces and calculating the momentum for each ball. They give examples of collisions and momentum in sports and understand...

Dalton's Playhouse is an interactive concept simulation meant to convey fundamental concepts in chemistry, including the law of definite proportions, the law of multiple proportions, and the law of conservation of mass.

Article explores the key points of Dalton's atomic theory and the laws of conservation of mass and constant composition. Which points do we still use today?

Hang various mass weights on spring scales while you adjust the spring stiffness and damping in this online activity. Slow down the action, take it to another planet, or watch the amount of potential, thermal, and kinetic energy.

A simple tutorial that includes interactive activities and videos to introduce the law of conservation of mass.

An interactive simulation that teaches about springs, Hooke's Law, and conservation of energy observing changes in kinetic, potential, and thermal energy by adjusting the stiffness and damping of springs holding various masses. This...

This lab experiment shows students that mass is not gained or lost during a chemical reaction. Lab also includes a set of lab questions that requires students to balance the chemical equation for the reaction that occurs in this lab.

Second graders explore the concept of law of conservation of mass.

[Free Registration/Login may be required to access all resource tools.] In this online tutorial students will explain the law of conservation of mass, the law of definite proportions, and the law of multiple proportions. They will also...

[Free Registration/Login may be required to access all resource tools.] In the following online tutorial students will describe chemical reactions using word equations and know the correct symbols to use in order to write skeleton...

Explore balanced chemical equations in this tutorial. Tutorial includes videos, interactive activities, and practice to help students understand balanced chemical equations and the Law of Conservation of Mass.

This site from Wilkopedia defines the law of conservation of mass. Included are links to related topics and terms used in the definition.

[Free Registration/Login may be required to access all resource tools.] Students take a closer look at how our understanding of the atom has evolved over time.

An article describing Dalton's atomic theory. Learn how this theory was the first attempt to describe a fundamental part of matter, atoms. Article also discusses where the theory is incorrect based on the knowledge we have today.
