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. 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 types of...

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...

The creator of this collection of chemistry slides is clever! Electron configuration is explained as, click-by-click, orbitals are displayed and then each is subsequently filled with the proper amount of electrons. After the progression,...

A unique and useful presentation, this covers projectile motion for your general physics class. Many graphs display the vectors involved, and some even act as animations. Motion is broken down into its components and only then are the...

Nineteen word problems dealing with frequency, speed, reflection, and refraction of light are provided here. Empower your physics masters to manipulate equations for computing angles, focal lengths, image heights, and more! This is a...

Force equals mass times acceleration. Physics whizzes apply this formula to six different diagrams, solving eight acceleration problems in all. This is a practical assignment, perfect for homework when practicing Newton's second law of...

On this homework assignment, physics novices draw force diagrams and compute the tension in various situations. Drawings help learners visualize each of six scenarios. This is terrific practice in solving problems with forces.

Here is a nifty worksheet on energy transfer. Physics fanatics analyze a diagram and state whether or not friction is involved. They sketch bar graphs and draw energy flow diagrams for each system as well. Circular motion, movement up...

Students collect rocks found locally and write a brief description which includes the name of the rock, whether the rock is sedimentary, metamorphic, or igneous, and what uses the rock has. They exchange rocks with another class in...

Here is an astounding series of lessons, designed for high schoolers, on environmental policy. By studying water conservation in rural India, the role of the government, and the reaction of the people, learners begin to formulate...
