Don't waste all that carbon dioxide. Scholars first produce carbon dioxide by mixing baking soda and vinegar. They measure the masses of the reactants and products to verify the law of conservation of mass. As a culminating activity,...

Learners characterize a physical change as something that changes to a different size, but retains its basic substance. They measure volumes using milliliters, and perform an experiment that proves that gases expand when hot and contract...

Bend it, but don't break it. Groups investigate the strength of different materials. Using a procedure in the seventh segment of a 22-part series on aviation, pupils determine how far a rod will bend. They determine the strength-to-mass...

A nine-page physics resource supports your lesson on acceleration. A step-by-step lesson plan walks you through the materials you need, the background information, steps for leading experimentation, and the explanation of the results....

In this atomic weight and ions worksheet, students answer questions about isotopes of atoms and how it relates to atomic weight. They also write out oxidation or reduction reactions for given atoms undergoing loss or gain of electrons.

Four diagrams of the atom and their subatomic particles and structures are given here and students should be able to complete the labels need to define the structures shown. The main structures defined are protons, neutrons, electrons,...

A comprehensive practice exam, this resource covers many areas of chemistry. The test includes 71 multiple choice questions on topics such as problem solving, chemical equations, chemical formulas, thermodynamics, acids and bases, and...

In a cross-curricular measurement and literacy lesson, your class will identify and compare cooking measurement instruments. They read a recipe and sequence a set of similar instructions in which the steps have been mixed up....

Details about matter and how it is classified are included here. The slides, with differences about homogenous and heterogeneous mixtures, have diagrams to support the definitions and your class will appreciate the summaries to assist...

Plenty of time was invested in creating this detailed presentation. The first slide alone includes several steps that support your explanation of percent composition, a precursor to understanding how to write empirical and molecular...

When a candle burns down, what happens to the mass that appears to be shrinking? Lesson begins with a demonstration of the chemical reaction of a candle burning. Then scholars use atom models to observe conservation of mass...

Most people realize they would weigh less if they were on the moon, but does it change how much weight you could lift if you were on the moon? Scholars adjust the mass of an object to be lifted and select between four different...

How do law enforcement officers determine the strength of an explosion based on the movement of objects around the point of origin? Scholars inspect the relative mass and velocities of two cars before and after an explosion. They perform...

Introduce your young scholars to the concepts of circular motion, projectile motion, angular speed, simple harmonic motion, torque, center of mass, centripetal force, and Hooke's Law with a 86-slide presentation. The circular motion...

How can a teeter-totter balance when the two people are different sizes? Show classes how this works through a simulation. Scholars play with a teeter-totter to show how different masses and their placement affect balance. Once they have...

Planetary atmospheres vary greatly from planet to planet. Explore these variations by experiencing the motion of the atmospheric molecules through an engaging simulation. Pupils discover that temperature and mass contribute to...

Why do some things float and others sink? A creative simulation allows learners to adjust mass and volume of an object to affect its buoyancy in water. A graph records the effect of each manipulation.

How did the earth become the mass that it is now? Your young scientists explore this question through the concept of density. Their inquiries consider the impact of gravity on the formation of planets. The culminating activity of the...

Add some zing to your swing! Explore pendulum motion through an engaging interactive. Physical science scholars specify the pendulum's mass, rod length, and starting angle before they observe the resulting angle graph.

Learning about the mole using rice is pretty nice! Help your chemistry scholars visualize the concept of a mole of substance with an easy-to-perform lab. Partnered pupils find the mass of a single grain of rice and relate this...

Can your physical science classes describe what happens when two objects collide? Whether they are new to the study of kinetic energy or just brushing up on their skills, pupils can observe the outcome of a variety of collisions...

In chemistry, the mole is a unit of measurement, much like a millimeter or liter. After learning about moles, scholars learn various equations relating to mass, volume, and concentration. They review each of these equations in a few...

When an organism eats, how does food become energy? Young biologists follow glucose through the process of cellular respiration to the creation of ADP using a discussion-based activity. The resource also highlights conservation of mass...

A short video introduces the triangle that illustrates how to find any value given the other two in the density formula. Class members use the triangle to work several problems to find the mass, volume, or density of an object.
