Students demonstrate how to use math skills to measure their lung capacity. In this human biology lesson plan, students use a clear plastic container, measuring cup and rubber balloons to demonstrate how the lungs work. Students estimate...

In this mineral identification learning exercise, students read nine vocabulary words and answer 5 short answer and fill-in-the-blank questions regarding minerals. There are four additional pages of related activities. 

Students make their own compost in a 2-liter jug and determine the actual volume loss in the composted material over a six-month period.

Students design a simple boat and predict how much weight it can carry. They should also discover why objects float or sink and how this can be determined experimentally. A great lesson on buoyancy!

Students explore the three states of matter. For this physics lesson, students are shown examples of solids, liquids, and gases. Students make cookies and identify the three states of matter during the baking process.

In this absolute zero activity, students experiment with a closed-end syringe and a ice bath and boiling water. They record volumes of gases in the syringe as well as temperatures of the water and they plot their experimental data. They...

Young scholars observe demonstrations that show adhesion, cohesion, equilibrium density, pressure of gases and solubility. In this gases lesson plan, students observe a demonstration of raisins, spaghetti, and popcorn moving up and down...

Students investigate the properties of solids, liquids and gases. In this states of matter lesson plan, students observe dry ice and its characteristics. They calculate the density of dry ice and observe the sublimation of the dry ice...

In this conversion worksheet, students solve 9 problems where they convert from one unit of measurement to another using a given table with conversion factors.

In this catalysts instructional activity, students use transition metal ions to catalyze oxidation reactions of iodide ions. Students measure the rate of the reactions by measuring free iodine as a product.

Students explore water properties by conducting a class experiment. In this buoyancy lesson, students utilize freshwater, saltwater, plastic cups, hard boiled eggs and food coloring to experiment with the floating capabilities of salt...

Learners determine which types of garbage are biodegradable and which are nonbiodegradable. They practice measuring skills, hypothesizing, taking data, and writing a lab report. Students observe the relative biodegradability of metal,...

In this calculations instructional activity, students find significant figures in numbers, they determine densities of substances and objects, they convert from one metric unit to another and they determine the appropriate unit of...

In this classification of matter learning exercise, students answer 15 questions about solids, liquids and gases, types of mixtures and compounds vs. elements. They also answer 2 questions about measurement and 1 question about a biome.

Fourth graders expand their knowledge about how the physical properties of a substances can be changed. They are given multiple opportunities, using first-hand experiences and familiar objects in different contexts, to identify...

Students investigate the properties of matter. In this properties of matter lesson, students observe containers of different metals and discuss their properties including density. Students find the density of an unknown metal and of...

In this electrochemistry worksheet, students solve 9 problems such as identifying masses of metals produced at cathodes, determining the potential of a cell's electrode and writing cell reactions along with their potential.

Students consider what happens to herbicides or insecticides that are used in agricultural practices, especially herbicides that are used to control noxious weeds. They become acquaint with a chemical assessment method known as...

In this ice on Mercury learning exercise, high schoolers read about the data collected from the NASA Messenger and the Arecibo Radio Telescope indicating the possibility of ice on Mercury. Students solve 6 problems including finding the...

In this chemistry review worksheet, students answer and solve 95 questions about chemical reactions, hydrocarbons, functional groups, moles, acids and bases and solutions.

Students are introduced to the periodic table of elements. They devise and perform and experiment in which they determine the density of specific elements. They use their results to predict the density of other elements in the same group.

Students perform two experiments to show the properties of enzymes. They use pectinase to produce apple juice from applesauce to show enzyme action and then taste the difference between raw and boiled papaya seeds as evidence of enzyme...

Students calculate the densities of several liquids that appear similar.  In this physical science lesson, students go beyond understanding the way liquids of different densities behave to researching how this knowledge applies in...

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.
