Fourth and fifth graders take a close look at oil spills and the devastating effects they have on the environment. They explore the various methods for cleaning up oils spills and perform and hands-on simulation of an oil spill in class....

Here is a great hands-on activity that should lead to a greater understanding of salt water, why the ocean is salty, and how ocean waves are formed. This terrific, old-school lesson has clearly described activities, and all of the...

Have your ever noticed that a cork floats in the middle of a glass that's filled to the brim with water, but will always float along the inside edge of a glass that's only half full with water? It's true! Young scientists ponder this...

In this chemistry worksheet, students examine the periodic table and how it is used in the context of interpreting compounds and their structure.

Introduce family vocabulary and practice with a sample family tree. If you're doing this lesson in class, consider showing the learners your own family tree as a model. Then have each learner create their own family tree. Post these...

In this science worksheet, students examine the graph with elements in order to differentiate atomic mass and categorizing the content.

This compendious collection of slides leaves no questions when it comes to the concept of atomic size. Thorough and easy-to-read graphs, tables, and graphics explain atomic radii, the shielding effect, the octet rule, isoelectric...

Through a variety of physical and theoretical situations, learners are led through the development of some of the deepest concepts in high school mathematics. Complex numbers, the fundamental theorem of algebra and rational exponents...

Circles are the foundation of many geometric concepts and extensions - a point that is thoroughly driven home in this extensive unit. Fundamental properties of circles are investigated (including sector area, angle measure, and...

Solids come in many shapes and sizes. Using geometry, scholars create two-dimensional cross-sections of various three-dimensional objects. They develop the lesson further by finding the volume of solids. The module then shifts...

Create trigonometric functions from circles. The first lesson of the module begins by finding coordinates along a circular path created by a Ferris Wheel. As the lessons progress, pupils graph trigonometric functions and relate them to...

Space scientists investigate the cosmic phenomena in order to search for answers to possible origins of the solar system. They consider the concepts of elements and  isotopes. Data is analyzed looking at tje abundance of elements...

The periodic table of elements is a vital tool for all chemistry apprentices and professionals alike. Here is a chance for your beginning chemists to assess their understanding of the periodic table. They list element names, symbols,...

In this electron configuration worksheet, high schoolers write the electron configurations of 22 elements and compare their valence electron configurations. They list the elements that are similar in terms of their electrons. They...

In this orbital diagram worksheet, students complete a graphic organizer by determining the orbital diagram for the 22 elements given.

Here is a top-notch handout to supply your chemistry class with. It covers valence electrons, Lewis diagrams, the octet rule, and more! Technically it is less of a activity than a detailed explanation of these chemical bonding concepts....

Here is a way for beginning chemists to review the skill of multiplying fractions! A segment of the periodic table of elements is presented at the top of the page, from which learners obtain the atomic number to use in six calcualtions....

Element groups are located in the periodic table by blinking on and off. A slide is then dedicated to each of the groups, explaining which elements are included and what common chemical properties they share. This topic is presented in...

Inquiry-based learning and investigations form the basis of a deep understanding of quadratic functions in a very thorough unit plan.  Learners develop recursive and closed methods for representing real-life situations,...

The brother-sister pair Carlos and Clarita need your class's help in developing their new pet sitting business. Through a variety of scenarios and concerns presented to the siblings, the learners thoroughly explore systems of equations...

The sky's the limit of what you create when combining functions! The module begins with a review of transformations of parent functions and then moves to combining different function types using addition, subtraction, and...

What caused the extra rotation? Class members visualize a coin rolling around the circumference of another coin. They determine the reason the rolling coin rotates twice. Further questions require them to determine a generalized formula...

It's probably a good idea to use the unit. Young mathematicians learn about conditional probability using Venn diagrams, tree diagrams, and two-way tables. They also take into consideration independence and the addition rules.

Students examine how to use energy more efficiently in their own home. They collect data from their home, complete a chart, read a power meter, interpret the data from an electric and gas bill, and create a poster demonstrating how to...
