In this stoichiometry worksheet, students use four balanced equations to calculate mole of products made, moles of reactants needed for chemical reactions to proceed and mass of reactants needed to produce products.

Students study matter. In this science lesson plan, students examine the relationships among gravity, weight, and mass, the metric measurement of distance and volume, and density and its application to physical properties.

In this periodic table worksheet, high schoolers complete a crossword puzzle given 22 clues about elements in the periodic table, periodic law, properties of elements and atomic mass and number. Students also fill in a periodic table to...

In this time intervals worksheet, high schoolers solve 8 problems where they determine the time gamma-ray bursts last, the time black hole micro-flares are emitted, the time coronal mass ejections travel and the days between lunar phases...

In this solar storms worksheet, students read about the correlation between different astronomical events to find patters and new 'laws' of nature. Students use given statistical information about solar flares and coronal mass ejections...

Prove the Law of Conservation of Mass through a lab investigation. A well-designed lesson asks groups to combine materials and monitor indicators for chemical reactions. Measuring the mass of the reactants and products allows individuals...

Investigate the Law of Conservation of Mass through a lab exploration. Individuals combine materials to initiate chemical reactions. They monitor for signs of reactions and measure the masses before and after the reactions for...

The third lesson in a series of 11 begins by using thermal decomposition of potassium chlorate to determine the mass percent of oxygen. Then a second activity allows scholars to demonstrate that the resulting residue is from a...

The difference between atomic mass and atomic number can be confusing for some young chemists. Help your class better understand the concepts by allowing them to sketch an atom on paper and then discuss their experience. Upon completion...

Accommodate your chemistry class with an experiment that is both entertaining and educational. Through the activity, blossoming chemists perform calculations on various isotopes, as represented by beans and legumes, to obtain...

How fun would it be to teach the concept of stoichiometry while allowing your chemistry class to assemble a classic campfire treat? This fun and engaging activity allows pupils to explore the principles of the chemical theory while...

Many people confuse atomic mass and atomic numbers. The sixth of seven lessons in a unit requires scholars to find the weight of different groups of pennies. Then, they must solve how many of each type of penny exists in a closed system...

Were it not for Sir Newton, our understanding of physics and matters of the world would be drastically different. Present your class with detailed information of Newton's Second Law as they explore the concepts of mass and acceleration....

The Law of Conservation of Matter can be complex for young scientists to fully grasp. Use this experiment to help simplify the process as pupils perform two experiments to determine mass: one that melts a substance and the other that...

Mass and density — aren't they the same thing? This activity has groups use balance beams and water displacement to measure several objects. The pupils use the measurements to calculate the density of the objects. 

Who said teaching a STEM instructional activity had to be challenging? Incorporate a career and technology-centered car build into your upcoming force lesson plan, and your class will be moving down the road in no time! Pupils practice...

Are brighter stars actually brighter? Turns out they are probably just closer! A presentation compares features of stars to our favorite star, the sun. In addition, solar lovers learn to classify stars based on their masses,...

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...

Learners explore atomic measurement in the first activity in a series of 36. Through readings, activities, and questions, classes review standard SI units, learn about Avogadro's constant, and use it to help them calculate moles. They...

What happens to the momentum of an object when it strikes another object? Scholars roll a marble down a ramp so it collides with another marble. By measuring the speed of each marble before and after the collision, pupils answer this...

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...

Young scientists build on their previous knowledge and apply it to coronal mass ejections. By plotting the path of two different coronal mass ejections, they develop an understanding of why most don't collide with Earth.

Most scholars associate density with floating, but how do scientists determine the exact density of an unknown liquid? The third lesson in a seven-part series challenges scholars to find the mass and volume of two unknown liquids. Each...

Set your historians up for testing success using this interactive flashcard tool. It is one of many learning strategies offered in this thorough online resource. Although designed for use with a text, the site is valuable independently....
