Have some physical science fun when studying the center of gravity or center of mass. Simply have balancing artists stand a dowel on one finger and keep it from falling over! A lump of clay is added and moved up along the dowel over a...

General chemistry class members engage in a mini-unit on mole conversions. Through nine lab activites with varying degrees of difficulty, they practice measuring mass and volume, molar calculations, and stoichiometry. Terrific...

Force equals mass times acceleration. Physics whizzes apply this formula to six different diagrams, solving eight acceleration problems in all. This is a practical assignment, perfect for homework when practicing Newton's second law of...

Young schoolers explore the concept of linear regression. They determine the mass and density of salt water. Pupils add salt to water and record the density as salinity increases, and perform a linear regression on the data to model the...

Sometimes modeling is the best approach to working with microscopic particles. A lab investigation models a fictional element using pasta. The setup uses three different pasta types to represent three different isotopes. Learners...

Whatever floats your boat. Young engineers learn about density by measuring the masses and volumes of boxes filled with different materials. Using their knowledge of densities, they hypothesize whether objects with given densities will...

How would a pendulum work on the moon or Jupiter? To answer that question scholars control up to two pendulums including their location, length, mass, and amplitude. Added controls include changing the friction and strength of gravity....

Check out a lesson plan that starts with force of gravity and moves through the concepts of mass, weight, volume, and density. Learners calculate density, test the buoyancy of objects, and then demonstrate understanding by altering the...

Get the ball rolling with this upper-elementary science unit on forces and motion. Offering over three weeks of physical science lessons, this resource is a great way to engage the class in learning about simple machines, friction,...

Pass along the knowledge of the great Sir Isaac Newton with this worksheet on the laws of motion. Including three separate problems, each involving multiple parts and calculations, this resource is a great way to...

Let's get moving! Newton juniors solve 19 problems using force, speed, and acceleration equations. This is a nifty learning exercise that includes a few diagrams and multiple choice selections for each question. It provides the...

Bouncing balls and rockets taking off provide ammunition for your physics arsenal. Your class will solve mulit-step problems for velocity, momentum, and force. This is an ideal homework assignment for practice solving motion problems.

Here is a general chemistry worksheet that incorporates practical applications. Four questions employ critical thinking about solutions, boiling and freezing points, and molar mass. Your class will practice what they learn in class by...

In this percent composition worksheet, students find the percent of each type of atom in a compound, they find the total mass of a sample and they determine the mass of particular atoms in a compound.

NASA presents a mini-unit on distances in our solar system. It incorporates scientific concepts of gravity, mass, density, and payload while your aspiring astronauts also employ mathematics skills. They calculate speed, they determine...

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 percentage worksheet, learners calculate percentages given various types of problems. They calculate percent of compounds in a solution, they calculate mass of compounds given percentages of solutions, and they percentages of...

Students calculate the volume of a specific mass of water placed in selected pieces of common laboratory glassware, using the density formula. They then determine the accuracy of the volumetric measurement for selected pieces of...

Students titrate a sample of fatty acids with standardized sodium hydroxide solution. From the amount of base needed for neutralization and the mass of sample used for titration, the apparent average molar mass of the sample is...

Have your class predict whether objects will sink or float in water. Learners consider a data table of mass, volume and whether the object sank or floated. They develop an evidence-based explanation for the results.

Students explore momentum. In this physics lesson, students perform an experiment in which two balls are released on slanted boards while students observe which ball will go the farthest and the fastest. Students define and explain...

For this scale worksheet, students use the SI system to compare the sizes of some of the smallest and largest organisms on Earth. This worksheet has 7 problems to solve.

In this gravity worksheet, students determine how much they would weigh on the different planets. Students calculate how far they could jump on other planets. This worksheet has 2 graphic organizers and 6 short answer questions.
