Here is a thorough lesson on safety in the chemistry lab. Chemists review a detailed list of safety rules, draw the layout of the laboratory area to include emergency equipment, identify hazard warnings, and consult the MSDS in order to...

Fourth graders watch teacher conduct the following experiment. Wearing safety goggles and old clothing is advised. The experiment could ruin clothing and hurt unprotected eyes. Follow the steps below having students write down what they...

Small groups complete a science project involving cleaning up an oil spill. In this experiment, pupils use 4 different sorbents to discover which one absorbs the most oil.  Afterward, they make a data table.

Students explore acids, bases, and indicators. They use turmeric solution, phenolphthalein, and goldenrod paper to determine the acidity and basicity of a variety of common household substances. A worksheet is included to record test...

Fifth graders investigate the formation and size of impact craters. In small groups, they conduct an experiment that involves dropping marbles into flour and measuring the impact from various heights and discussing their hypothesis and...

Students explore epidermal cells. After following specified procedures for removing epidermal cells from their wrist, students view the cells with the use of a microscope. After creating a drawing of their observation, students label the...

Students explore the light spectrum. The teacher uses holographic diffraction grafting film on an overhead to demonstrate the true nature of color. After observing a vivid rainbow, students recognize that white light is composed of all...

Students learn along with Ms. Frizzle's class. In this Magic School Bus lesson plan, students test whether gravity makes heavier things fall faster than lighter ones.

Middle schoolers wxplore acids and indicators by watching a demostration in which "magic" ink appears. They duplicate the demonstration by writing magic messages using phenolphthalein solution and painting the message with vinegar to...

Students explore Ultraviolet detecting beads and conduct several investigations with them.  In this investigative lesson students participate in an experiment to see the harmful effects of UV light and discuss their findings. 

Students are able to prepare and use pH indicators in paper form. They find out the color of the indicator paper plus test solution may change with time. Students use red cabbage to use for the indicator.

Students explore visosity of matter. They run tests of various liquid substances to observe and compare rates of flow of different substances. In addition, they relate viscosity to distance travelled by sample substances.

Students practice determining liquid densities in a short, hands-on lab activity. Students use a graduated cylinder to measure out 100 milliliters of a liquid, find its mass using a balance, and record measurements in a data table....

Students create a synthetic dye and oxidize the dye and record the effects.

Eighth graders examine what materials cause water hardness and the relative measure of water hardness in a two part lab activity. In part one, 8th graders add an assigned soap test solution to eleven different test tube solutions in...
