What happens when two worlds collide? In the first of several activities, future physicists experiment with colliding ball bearings or Newton's cradle. Another activity requires the use of an air track with cars to examine collision....

Can you disprove the law of conservation of mass? Pupils observe the teacher weigh each part of a reaction. Then, the teacher weighs the result of the reaction and everyone sees that the products do not equal the reactants. Then they...

Take a "conservative" approach to planning your next unit on mass and matter! What better way to answer "But where did the gas go?" than with a lab designed to promote good report writing, research skills, and detailed observation....

Whoa! What just happened? That's right, change is everywhere. But what exactly is changing? Middle school science sleuths get to the bottom of the changes matter can experience. Through simple demonstrations, engaging videos, and an...

Equip your chemistry class with the tools to properly understand endothermic and exothermic reactions. Young chemists collect, analyze, and graph data to determine how the Law of Conservation of Matter is applied to chemical...

The third instructional activity 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...

Bubble, bubble, boil and trouble! What causes common substances like baking soda and vinegar to react the way they do? Welcome your junior chemists to the wonders of acid-base chemistry using a comprehensive and fun...

Stars exist from a few million years to over 10 billion years, depending on their mass. Scholars perform a play acting as stars to learn about their different life cycles. They develop an understanding of many of the fundamental concepts...

Is your class in the dark about photosynthesis? Shed some sunlight on an important biological process with a thoughtful activity. After answering questions to help determine their level of knowledge, learners work with chemical equations...

How high will it bounce? Groups determine the height different balls bounce off of different surfaces. By performing the necessary calculations, they determine the initial and final momentum of the balls. The included worksheet provides...

Planning a unit on simple machines? Save some time and energy with this collection of lessons and activities that explores how these devices are used in the real world to make life a little easier. 

How do humans get energy since they aren't mechanical and can't photosynthesize? Learners explore this question by relating potential energy in food to human energy levels. Scholars measure the change in mass and a change in...

Try not to blind anyone with science by following the safety rules. The lesson encourages scholars to form an ionic compound from magnesium and chlorine. Then they determine the empirical formula and determine the mole ratio and percent...

How do one's habits and lifestyle choices affect the environment? Through a short online survey, learners will calculate their own carbon footprints then determine how to reduce their impact on the environment through simple steps, such...

Get into the swing of things. Pupils use a pendulum to demonstrate the conversion of potential energy to kinetic energy and back. After measuring the speed of a pendulum and compare it to the calculated theoretical speed, they...

Hot off the presses, this collection of thermal energy activities, lessons, and printables is sure to amaze. Demonstrate how thermal energy moves about in a system using simple materials. Pupils demonstrate their understanding...

Polymers are an important part of our day-to-day lives, but how much do your pupils know about them? Learn the basics and beyond in a series of activities designed to build skills in observation, planning, organic chemistry, and bonding.

Teaching is a balancing act! Keep things on an even keel with a comprehensive equilibrium lesson plan. The resource covers reversible and irreversible reactions, Le Chatelier's Principle, and the industrial applications of equilibrium...

Shocking! Who knew so many great ideas existed for teaching middle schoolers about electricity? Find them all within this energetic framework. You'll light up at the variety of printable and web-based resources within! After building...

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...

The radical reactions of polymers seems abstract to many pupils, but this lesson turns them into a fun building game. Scholars use dice and building pieces to build polymers. Then, they determine the theoretical and experimental weight...
