It's not often that you come across a clever laboratory activity that is both imaginative and comprehensive! Using M&M's and Reese's peanut butter candies to represent two different clam species, young biologists test for "relative...

This is a tremendous overview of the tiny atom. Journey through the history of human understanding of this basic building block of matter. Examine each of the sub-atomic particles in detail: neutrons, protons, electrons, quarks. Peruse...

Peer review of science laboratory reports? You bet! First, learners work in pairs to review a scientific article. Then they trade lab reports for peer review. The end result is the publication of a classroom scientific journal!

Students complete a variety of activities as they examine the ethical issues behind stem cell research and cloning. They make their own ethical decisions on both subjects.

Diamonds are a girl's best friend! Crystal labs can be a science teacher's best friend because watching crystals develop is fascinating, and it results in such a pretty product! This activity is unique because the crystals are grown...

General chemistry class members engage in a mini-unit on mole conversions. Through nine lab activites with varying degrees of difficulty, they practice measuring mass and volume, molar calculations, and stoichiometry. Terrific...

Reebops are cute, marshmallow-based creatures that can be used to teach inheritance. Beginning biologists draw strips of paper that represent chromosomes from two envelopes, one for the father, and one for the mother. Each parent...

High schoolers focus on a study of igneous rocks. They see how igneous rocks are formed, and how to distinguish them from other types of rocks. A crystal-growing activity is present, and learners create drawings that show where each...

A fantastic lesson on urban air pollution problems throughout the world is here for you. Learners understand that there are many factors involved in creating pollution, that there are many health effects brought on by air pollution, and...

Challenge your physics class to implement their knowledge of electric fields by completing this learning exercise as homework. There are 15 problems to solve, for which pupils compute electrostatic force, electric field strength, and...

Chemistry stars experiment with metals to observe reactivity with salt solutions. They test magnesium, zinc, iron, and copper by immersing them into different solutions and observing for changes. A separate set of data tables is...

Is butter better? In terms of saturation, young chemists find out! Using titration methods, they will compare the degree of saturation of butter with that of margarine. Knowing the unsaturation, they can make conclusions about the...

Whether in the UK or the US, the mass of the copper in a copper alloy penny can be determined. If you are in the US, note that on the lab sheet, a penny is identified as a "1p piece." The penny is dissolved by young chemists in nitric...

Explore the properties of solutions with a lab activity. Chemistry fans determine the boiling point of water, add salt to create a solution, and then repeat the process four more times. They design their own data table and then graph the...

Rather than simply matching up the ionic charges on paper, this exercise gets chemists into the lab to determine the chemical formula for magnesium oxide! If a known amount of magnesium is used, an oxidation reaction results in this...

This publisher has put out some terrific laboratory activities for your aspiring chemists! This edition uses displacement reactions to develop a reactivity series for three halogens. Not only do they explore the reactivity of bromine,...

Accomplished chemistry learners set up a calorimeter and measured the energy released by various alcohols: methanol, ethanol, and either propanol or butanol. Lab masters will first need to design their tables for recording data. Consider...

During this lab activity, chemists discover the reactivities of chlorine, bromine, and iodine as examples of the halogens. They use a displacement reaction as a test by adding other compounds and observing for a color change. The lab...

Students explore a computer-aided design program. Students chart out roller coaster design, computer graphics and architecture. Students focus on understanding the connections between mathematics, science, technology and innovation.

Students research abiotic and biotic factors concerning the concept of an ecosystem. Record and analyze data collected. Write a lab report in proper and scientific format with thinking and analytical skills. Work as a cooperative team.

Biotechnology pros produce their own biofuel using waste oil and fresh vegetable oil. They test the quality of their product using titration techniques and pH analysis. They write their observations and report their findings. Be aware...

Sedimentary rocks are the building blocks of this geology lesson plan. In it, learners discover what sedimentary rocks are and how they form. They understand the differences between the major sedimentary rock varieties and learn what...

After taking in background information on teeth, marble, eggshell, and fluoride, chemistry aces design an experiment. Their goal is to demonstrate whether or not fluoride has a similar effect on marble or eggshell as it does on tooth...

Brief, but beneficial, this little gem displays the workings of a hydrogen fuel cell. A simple black-line diagram has question marks at the input and the output, as well as in the middle of the cell. Click on each question mark to reveal...
