In this chemical reactions worksheet, students are given the reactants of equations and must complete each equation by writing the products and balancing the equation. They must also identify the type of reaction.

Don't compromise the identity. Given pairs of equations, scholars determine whether the equations are true for the same set of values. They explain their reasoning, considering whether it's possible to combine the equations into an...

How many times can eager mathematicians catch the waves? Pupils find the solutions of three different trigonometric equations. They then determine the effect of the slope of a line that intersects a trigonometric function and the number...

Students are able to draw a diagram of the light reactions and briefly describe what is occurring throughout the process. They are able to explain where each reactant/product in the photosynthesis equation comes from/goes during the...

Is it possible for an equation to be a function and not a function at the same time? By completing a short assessment, young mathematicians answer this question. Class members provide an explanation on how an equation represents a...

Class members have some catching up to do. Given a linear equation describing the distance of a runner, young mathematicians interpret the equation in terms of the context. They consider a general equation of the same form and describe...

This review sheet will be very useful to test your pupils' understanding of battery structure and redox reactions.  The questions ask for equations to be balanced and for the traditional equipment setups to be drawn and labeled....

If you know how to employ the exothermic reaction between hydrogen gas and oxygen gas to make a miniature rocket, then this worksheet is a fabulous lab sheet for your chemistry charges. First, they observe a spark in pure oxygen and one...

Twelve questions about the various calculations of mass and yield are given here.  There is significant practice of molarity calculations and consideration of the reactant and product balance.

Each of the slides here gives a definition, equation, or calculation example for a component of force and motion. This large collection covers topics from momentum and Newton's laws to centripetal forces and simple machines. Animations...

In this density activity, high schoolers are given 11 problems and they determine the density of the substance, the mass of the substance or the volume. They write the equation they use to solve the problem, they show their work and they...

Your algebra students double their money monthly in this task based on a checking account balance. Learners write an equation to model the situation and then use their model to answer contextual questions.

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...

A great way to learn about molecular structures is to make a model. Gumdrops and toothpicks are used to construct crystal models. The models are based on theories of crystal shapes that occur because of positive and or negatively charged...

Somehow 55 chemistry problems have been squished onto a single page! Don't assume that it is a mess, however. High school chemists write the products for different types of reactions. Then they identify the type of reaction in addition...

Here is a laboratory exercise in which chemistry masters conduct an oxidation reaction to change ethanol into ethanal. They compare the original alcohol to the resulting aldehyde by forming a precipitate. This activity is aimed at...

Turn aluminum cans into pickles! An engaging experiment has learners chemically change aluminum into a substance with many purposes including the manufacture of pickles. After performing the chemical conversion, the experimenters verify...

On Earth, a candle flame points up, but on the International Space Station, it forms a sphere. Young scientists practice their skills by recording observations before, during, and after a candle burns. Chemical and physical...

How well do your young chemists know their acid-base reactions? Reinforce neutralization reaction and problem-solving skills with a challenging interactive. Learners examine the reactants, then predict the outcome in a series of...

Colorful lead compounds never fail to impress! Solubility scholars examine a series of double replacement reactions involving lead nitrate and record their observations. The second part of the experiment illustrates the differences...

Parent functions and their combinations create unique graphical designs. Learners explore these relationships with a progressive approach. Beginning with linear equations and inequalities and progressing to more complex functions,...

In the United States, most trains operate at a top speed of 100 miles per hour. Scholars use information on the distance and time of a train trip to determine if the train ever reaches a specific speed. They connect pieces of information...

In this stoichiometry homework activity, students balance each chemical equation. Students calculate how many grams, moles, and molecules are present in each problem provided.

In this stoichiometry worksheet, students calculate balance the chemical equations and then calculate the moles needed to complete or activate the chemical reaction. Students also calculate the volume or grams needed for each chemical...
