Students review balancing chemical equations. In this chemistry lesson, students calculate moles of an unknown substance based on stoichiometric relationships in the balanced equation. They cite applications of stoichiometry in the...

Students explain the importance of the five main biogeochemical cycles. In this chemistry lesson, students discuss how ions are transported in the environment. They design an experiment to collect data on eutrophication.

Students predict the product of chemical reaction using the solubility rules. In this chemistry instructional activity, students balance ionic equation. They perform a lab to check if their predicted products are correct.

Students predict the shape of molecules using VSEPR theory. In this chemistry lesson, students differentiate a polar and nonpolar molecule. They discuss why water's polarity is very important.

Students conduct a series of activity that demonstrates Charles' and Boyle's Law. In this chemistry lesson, students determine the relationship among pressure, volume and temperature. They solve problems using mathematical equation.

Students explore online tutorial on polymers. In this chemistry lesson, they create two polymers in the lab and compare their properties. They write a sales letter about their new and improved polymer product.

Students perform computer simulations on air dispersion. For this chemistry lesson, students calculate energy transfer based on specific heat and temperature change. They explain the causes of smog.

Students calculate the concentration of different solutions. In this chemistry lesson, students explain what a solution is. They explain ways to change the concentration of a solution.

Students differentiate metallic, ionic and covalent bonding. In this chemistry instructional activity, students explain how these bonds are formed. They classify substances according their bond type.

Eighth graders identify the three main types of chemical bonds. In this chemistry activity, 8th graders draw Lewis dot diagrams of elements and determine the bond formed. They create a model water molecule.

Students identify the different types of polymers. In this chemistry lesson, students research information about an area of polymer science they chose. They create a PowerPoint presentation to share their findings in class.

Students explain the advantages of nanotechnology. In this chemistry lesson, students investigate pretzels' average diameter and circumference. They graph their result and compare with other groups.

Students discuss the layers of the atmosphere, and the history of the ozone hole. They discuss the chemistry of the ozone formation. Students compare seasonal data collected with ozonesondes. They compare Antarctic and Arctic ozone hole...

In this chemistry worksheet, students complete an adopt an element information sheet. Then they create an advertisement for their element including the information listed. Students also write its important uses, interesting facts, and...

Students differentiate the different phases of matter. In this chemistry lesson plan, students conduct several hands-on exercises to discover how matter transforms when mixed together. They identify the different stages in the water cycle.

First off, Newton's laws of motion aren't often taught at 2nd grade, so this lesson may be more appropriate for upper elementary learners. It begins with a discussion and demonstration of the laws of motion, and then has individuals...

Explore the importance of a concentration gradient in the rates of dissolution. Using the ocean ecosystem, learners study rates of dissolution around coral reefs. A hands-on experiment helps individuals discover the effects of changing a...

Carbon is the most common element on earth, so the innovative discovery of a new type of carbon molecule won the 1996 Nobel Prize. In the ready-to-go lesson, scholars learn about C60 and how it has opened up the entire area of...

Scientists recently discovered several previously unknown species at the Bear Seamount off the coast of New England. Scholars research these new species — benthopelagic, benthic, and seamount fish — and find out what makes them...

This is one super model interactive! Middle and high school science scholars examine scientific models through a simple resource. Guided, hands-on practice allows them to classify conceptual, mathematical, and physical models. Other...

Cellular respiration and photosynthesis relate closely, but many don't realize how. Scholars drag and drop the reactants and products to the chemical reactions for both processes. Then they answer three multiple-choice questions.

Two-axis rotations ... twice the fun as one-axis rotations! The last installment of a five-part module teaches scholars how to conduct two-axis rotations. They create isometric drawings before and after the rotations.

Tenth graders engage in a lesson looking for the ideal conditions for microbial growth. The lesson is to be given once they have background knowledge about microbes. Students set up a lab in order to grow cultures over a period of two...

High schoolers are able to use a secchi disk to measure the turbidity of water by determining the depth at which the sechi disk is no longer visible and using the data in a formula to quantify the results. They are able to use Vernier...
