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 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...

Once I told a chemistry joke, but there was no reaction. Get young chemists involved in changes and reactions with a presentation that begins with physical and chemical changes and chemical reactions. It moves on to chemical...

Middle schoolers explain that while cities have unattractive features, the density of human life enables energy efficiency, mass transit, recycling, and other benefits which are difficult or impossible in rural areas. This is the fifth...

Can you go ice fishing in the ocean? Learners examine the freezing point of different saltwater solutions. Each solution has a different concentration of salt. By comparing the freezing points graphically, they make conclusions...

In this matter and energy worksheet, students identify substances as solids, liquids or gases, they use the kinetic theory to describe the motion of particles and they explain the conservation of mass and energy when a substance changes...

If you have a rotating office chair in your classroom, you can have physics pupils participate in this simple, yet effective demonstration of angular momentum. One partner sits in the chair, arms outstretched, holding heavy weights. The...

In this chemical reactions worksheet, students are given fifteen unbalanced equations and they must identify the reaction types, the phases of the products, the signs that a chemical change occurred and the sum of the coefficients of the...

Viewers learn how to identify the substances in a chemical reaction, how to balance it, and the different types of chemical reactions by watching a presentation that also includes a review of monomers and polymers. The presentation...

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...

Learners experiment with different types of metal by dipping them in boiling water and cool water and recording temperature changes in the water. By doing this, they find the specific heat of the metals.

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. 

The first STEM lesson in a group of 10 explores composting. After discussing how to make a better tomorrow, classes are challenged to track garbage in their communities, visit a local waste management facility, and conduct a survey...

Learners, using wood blocks and model boats, investigate how the shape of an object affects friction it encounters as it is drawn through a towing tank.

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...

All sodium carbonate may not have the same amount of carbonate, but it should have the same percent. Learners write and balance an equation to predict the chemical reaction between sodium carbonate and zinc acetate. Through the lab...

What is water worth to you? The answer probably depends on many different variables. Learners explore the value of water in space and what it takes to transport the resource to locations in a galaxy far far away. They then consider...

In this balancing equations worksheet, students balance ten equations by placing the proper coefficients in front of reactants and products to balance the number of atoms.

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.

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.

In this energy lesson, students create calorimeters out of soda cans and use them to calculate the amount of energy stored in different types of wood.

Students apply the principles of chemistry to investigate the concept of how a hydrogen powered car works. They study the electrochemical reactions that provide the energy source. Students also record observations in the functioning of a...

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.   

Eighth graders analyze physical change in mass. In this chemistry instructional activity, 8th graders describe, measure and calculate the amount of physical change occurring in mass before and after the change. Students should be...
