Crystals form before your very eyes! What sixth grader wouldn't enjoy this lesson on igneous rock formation? Using hot Salol, junior geologists observe the crystal formation process as the material cools. This comprehensive lesson plan...

Geology geniuses analyze sediment samples with a hand lens and sort according to physical characteristics. They also learn about the processes of cementation, compaction, and lithification within the rock cycle. The lesson plan is...

Even though the student handouts are not included in the write-up, this lesson plan contains the instructions for terrific activities to use when teaching middle schoolers about metamorphic rocks. First, they compare granite to gneiss...

Ground-truthing ... is it even a word? The last installment of a five-part series analyzes how scientists collect sea surface temperature data. Scholars use government websites to compare temperature data collected directly from buoys...

Join Congress as they assess their economic abilities for spending—and as they discover their limits. High schoolers use an educational resource to explore Congress's economic powers and learn to apply these concepts to their everyday...

Advanced lab apprentices prepare zinc and copper solutions to which they will compare the same minerals from a multivitamin. Using absorption spectroscopy, they analyze the contents of the multivitamin for concentration. This lab can be...

In this chemistry worksheet, learners calculate the titrations of various types of chemistry problems. The questions include background information.

Get your class outside to observe their surroundings with a lesson highlighting weather patterns and seasonal changes. First, learners take a weather walk to survey how the weather affects animals, people, plants, and trees during...

Explore the consistency of the earth's layers and soil through modeling. By conducting an engaging experiment, learners develop a model for the earth's layers and a soil profile using edible materials. Each material is chosen based on...

Poetry is all about sound and rhythm. The sound of the words, the rhythm of the lines, and the emotional atmosphere created by these elements and the literary devices poets use, compress whole stories into a few stanzas. The specialized...

Rings and golden nuggets contain the element gold, but how small can you break it down before it is no longer considered gold? A helpful presentation explains the basics about atoms, elements, and isotopes through a presentation.

Pupils learn of multiple ways astronomers look for planets outside of the solar system. By completing a hands-on activity, scholars discover that trying to see the planets directly because of the glare from the nearby star is nearly...

Ninth graders find the height of every day objects using techniques learned through postulates that allow triangles in a problem to be similar. They calculate the length of a missing side and solve proportions.

Students find the identity o sine, cosine and tangent. In this precalculus activity, students solve and identify the different parts of a right triangle. They use the ratios of the Pythagorean Theorem to find the missing side or angle.

Pupils examine how photosynthetic rates can change by using different qualities of light. They practice using spectrophotometer and the scientific method to detect the absorbance values in light treatments.

Learners investigate the side splitter theorem. In this geometry lesson, students estimate and solve problems dealing with ratios and proportions. They identify angles created by lines that are parallel.

High schoolers pretend they are hiking up a mountain. They practice making calculations on angles and elevation. They use topographic maps to estimate distances and trigonometric ratio methods.
