How do 2-D properties relate in 3-D? Lead the class in a discussion on how to draw and see relationships of lines and planes in three dimensions. The ability to see these relationships is critical to the further study of volume and...

A one-stop resource for exponents, square and cube roots, scientific notation, and volume formulas guides learners through properties of exponents. As they learn to apply these properties to operations with scientific notation,...

Need a less abstract approach to introducing extraneous solutions? This is it! Young mathematicians explore properties used to solve equations and determine which operations maintain the same solutions. They...

Solutions for linear equations create solution sets. Pupils watch a video on solving multi-step linear equations. They then solve equations with variables on both sides of the equal sign, combining like terms and the distributive...

A full-fledged practice final prepares pupils for their general chemistry final exam. If they complete these 57 multiple-choice questions correctly, they will be well-prepared. Note: even though the questions are multiple-choice, there...

Develop multiplication skills with your class. Youngsters will visualize multiplication as repeated addition. Then they will create a multiplication bug book and discover arrays as a strategy for multiplication problem solving....

Compliment your lesson with this periodic table presentation. The slides are clear summarizing the origins and main details of the periodic table very nicely.  The overall appearance, images, and bullet points are logical and some...

There is a step-by-step example here to help young multipliers solve 12 equations, all of which have one 2-digit and one 1-digit factor. The method displayed encourages breaking the two-digit number into tens and ones, multiplying each...

The Declaration of Independence was published in 1776. The Declaration of Sentiments and Resolutions, modeled after the Declaration of Independence, was drafted and read by Elizabeth Cady Stanton at the Seneca Falls Convention in 1848....

Students develop their own techniques for drawing a small sample of solutions into a straw. They hypothesize ways to increase the density of water, and discuss how salt-free rainwater tends to float on top of salty seawater.

Understand how chemical reactions recombine atoms to create the "chemicals of life". An experiment, showing the basic chemical reactions of an iron nail or a match, helps young children start their understanding of permanent changes.

Students determine the base metals and surface metals in a penny. In this analysis of metals lesson plan, students determine the density of five pennies minted in different years. They use different chemicals such as hydrochloric acid,...

Chemistry lab learners experiment to identify a series of unknown compounds. They choose which tests to perform, but you may suggest melting or boiling point, solubility, electrical conductivity, and malleability. This is a terrific...

Lights, shadows, action, and inquiry await your artistic scientists. They explore the way light travels, absorbs, reflects, and transmits through shadow play. They create folktale-inspired shadow puppets, explore the science of light,...

Young investigators conduct an experiment using the scientific method. They see how many drops of water fit on a coin; have them conduct several different trials. This involves making a hypothesis, looking at controls, and introducing...

Get your historians to hop into someone else's 18th century shoes with a simulation on rights in early America. Each individual gets an identity card, indicating their race, gender, and status (slave or free). Areas around the room are...

Adolescents love to shop, especially when an item is discounted. Here, shoppers only have a set amount of money to spend. Will they be able to make a purchase with the discount and tax added in? Percent discounts can be calculated...

Make a game out of solving equations. This particular activity works well for pairs of learners. Follow the instructions to have player one pick a number and player two verbally give an equation. Participants need to make sense of a...

Experiment with light and shadow with a photography lesson. Learners first view several artistic photographs. They then play with different levels of light and various objects, eventually putting together compositions and taking pictures...

Young geologists discover the important role that rocks and minerals play in our everyday lives through this series of hands-on activities. Starting off with a lesson that defines the difference between plants, animals, and...

Not all linear functions are linear transformations, only those that go through the origin. The third lesson in the 32-part unit proves that linear transformations are of the form f(x) = ax. The lesson plan takes another look at examples...

Apply the properties of exponents to expressions with negative exponents. The fifth activity in the series explains the meaning of negative exponents through an exploration of the properties taught in the previous lessons of the...

Assess your young mathematicians' knowledge and understanding of the properties of exponents. The questions in the seventh lesson of 15 incorporate the properties learned in the first six modules of this series. Individuals use and apply...

Why are the properties of the water important when exploring the ocean? Young scientists discover the tools and technology used in deep sea exploration in the fourth installment in a five-part series. Groups work together to...
