Simulate soil sample assemblages. Individuals create soil layers in a cup. They then use straws to collect core samples from these layers. What information can they glean from the core samples, I wonder?

You won't get a stomachache doing an investigative experiment. Pupils simulate the effect of antacids on stomach acid. Obviously, they won't be using real stomach acid; diluted hydrochloric acid serves this purpose.

Learners study the scientific evidence about carbon dioxide emissions. They learn to calculate the amount of energy used by different appliances. They complete a worksheet which analyzes the amount of energy that their home uses.

Young ornithologists watch an informative video and use the Internet to gather data about the life, size, habitat, and migration of hummingbirds. The interdisciplinary lesson includes activities that target art, science, math, and...

Whatever floats your boat. Young engineers learn about density by measuring the masses and volumes of boxes filled with different materials. Using their knowledge of densities, they hypothesize whether objects with given densities will...

You will appreciate a useful learning exercise for grasping an understanding of liquid volume and practicing metric unit conversions. All of the problems involve liters and milliliters, so the conversions are very elementary. Neat...

This demonstration of solar ponds can be used in an earth, environmental, or physical science setting. Lab groups set up a solar pond and model how it is able, due to a salt concentration gradient, to maintain heat for future use. 

Create a little scientific magic within your classroom! Learners mix powders and liquids and identify chemical reactions. Based on the reactions, individuals determine the identity of various powders.

Demonstrate food preparation techniques of salads, soups, casseroles, breads, meats, poultry and pastries.

High schoolers test for the presence of enzymes in fruit and the specificity of those enzymes, as well as to identify and show the susceptibility of enzymes to certain environmental factors (temperature and pH) originating in the...

Young scholars reinforce math skills while learning about best practices for protection of water quality in the management of animal feeding operations. They make a table to show results of their calculations and compare and justify...

Students explore matter. In this physical science instructional activity, students role play the 3 states of matter forming "liquid" molecules and "solid" molecules with teammates. Students perform an experiment in which the result...

Students perform experiments in pairs to visualize the changes in water during freezing and melting. In this properties of water lesson, students use their senses and inquiry tools to understand the changes in state of water. Suggested...

In this metric system worksheet, students complete notes on measurements used in the metric system, the metric system prefixes and estimates of measurements of length in centimeters.

Students participate in experiments at five stations to practice measurement. In this measuring lesson, students are presented different produce and objects and must measure with an appropriate tool. Students use metric and customary...

Students examine the changing states of water. In this solid, liquid, gas lesson, students discover that water changes when heated or cooled. Students make predictions and then use the interactive whiteboard to "heat and...

Students experiment with thermal insulators. In this heat transfer lesson plan, students predict and then measure heat loss from a cup of water using different materials as insulators. Students complete a line graph to display their...

If students use and store kitchen equipment appropriately as well as utilize sanitary work habits, the foods laboratory will be a safe and easy place to work. See Preface Materials: As a motivator ask: "Why should I worry whether or not...

Young scholars use the scientific method to complete to experiments that have visible reactions. In this visible reaction instructional activity, students participate in an experiment with melting ice and one with inflating a balloon....

Take a "conservative" approach to planning your next unit on mass and matter! What better way to answer "But where did the gas go?" than with a lab designed to promote good report writing, research skills, and detailed observation....

Snow, ice, and water are all composed of H2O. Does that mean they all have the same volume? Discover the ways that the densities of these substances determine their volumes, and how they change based on their current states of...

Learn about radiation, convection, and conduction with a multiple choice worksheet. Each question prompts kids to decide what is different about each form of heat energy transfer, and what is the same.

You won't regret being stuck with this activity. By mixing a variety of household items, pupils create their own glue. They test the tensile strength of their glue and compare it to that of other adhesives.

In search of an organic lab that employs real-life techniques and analysis methods? Groups carry out the nitration of methyl benzoate, then attempt to determine the number and location of the nitro groups added to the benzene ring....
