In a hypothetical scenario, food chemists use titration to concoct a brine solution for producing the crunchiest pickles. They also analyze store-bought pickle juices. In addition to reinforcing titration techniques, the lesson requires...

In this chemistry Olympiad lab worksheet, students are given two lab problems to design experiments. Topics include determining the mass percentage of a given compound and determining an unknown metal using quantitative and qualitative...

Playing with balloons, water, oil, and bottles help put this instructional activity over the top! Participants use air-filled balloons in water tanks to experience gas compression. They also use oil-filled bottles to experiment with...

High schoolers design an experiment to test for the concentration of chloride in products. In this analysis of chloride concentration lesson plan, students develop and conduct an experiment to find the amount of chloride ion in a...

Two laboratory problems are put forth for chemistry students. They are to plan and carry out an experiment that will answer each of the questions. The first asks them to investigate a relationship between the surface area of a potato and...

A scenario is presented for chemistry techs to address. Using titration techniques, they must analyze hydrogen peroxide solution samples. They evaluate accuracy and precision in the process. They also gain experience consulting the MSDS...

Here is a comprehensive method for assessing chemistry learners' knowledge; have them approach two laboratory problems, plan their methods of solving each, and then actually carry out the experiments to find the answers. Both the...

Here's a five-star lesson plan in which inquisitors conduct sophisticated experimentation with cellular respiration in plant seeds. Placing seeds in a closed system they measure the amount carbon dioxide produced and relate it to...

Open this lesson by demonstrating the production of acidic carbon dioxide gas by activated yeast. Emerging ecologists then experiment with seashells to discover the effect of ocean acidification on shelled marine organisms. They measure...

Have you ever wondered what roundworms are like? Or what they don't like? Explore the sensory preferences of C. elegans through this controlled chemotaxis experiment. Biology class members brainstorm what substances might attract—or...

The principles of levers and simple machines are presented here. An easy-to-make lever is constructed by each group of scientists, and they use it to explore how this simple machine makes heavy things so much easier to lift and move. A...

Teaching elastic forces in your physics class is a snap with this resource! Scholars compare the stretch of rubber bands with differing width, then measure the stretch of a spring and calculate force. In a whole-class experiment, wire is...

Five fabulous procedures introduce physics or chemistry classes to special properties of matter. They discover adhesion and cohesion, solubility, melting and boiling points, and viscosity through hands-on experiences. Tests are...

Physical science learners conduct a simple experiment using the heat of their hands to affect the fluid pressure. They place a balloon atop a freezing cold bottle and observe what occurs as it warms up. Both activities demonstrate how...

The first activity may not work for your class if you don't have access to an open area of 30 meters and two cars of different masses, but the remaining activities can be used in any physics course. They all involve the investigation of...
