In this weathering worksheet, students use limestone chips and acidic solutions of pH 2 and 7 to determine if acidic solutions contribute to the weathering of rocks. Students determine which pH weathered the rocks the most.

Students use the scientific method to investigate the role of temperature in microbial growth. In this food preservation lesson, students set up an experiment with fruit in room temperature and in a refrigerator. They record the...

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...

Students investigate how selection occurs in a random population. The concept is that selection affects evolution.They demonstrate how selection occurs and will analyze shifts in the populations. They design their conclusions with M...

Students find the density of two substances. In this density lesson plan, students determine the density of water and ethyl alcohol and compare their densities. They enter their data into the computer to produce a class compiled graph....

Learners produce copper metal by electrolysis. For this REDOX lesson plan, students use a copper (II) chloride solution and a 9 volt battery to produce copper metal through an electrolysis reaction. Learners make observations and take...

In this relationships and biodiversity worksheet, students investigate the relationships between 4 plants sample using 7 different tests. These include looking at structural characteristics of the plants, seeds and stems, using paper...

For this chemical and physical change worksheet, students conduct a variety of experiments with unknown solutions and make observations. Students determine if the properties of the solutions have changed and if there is...

Students build a telescope and give quantification of its magnification and field of view while making observations regarding images. In this telescope lesson, students use a simple lens to project a scene and examine various telescope...

In this ellipse activity, students learn the difference between an orbit and an ellipse. They draw ellipses and calculate the distance between foci, they calculate the length of the major axis and they determine the eccentricity. They...

Students build a water table to show the zones of aeration and the zones of saturation. In this water table lesson plan, students use a beaker with sand and gravel to simulate the Earth's water table. They label the zones of aeration and...

Young scholars examine a method biologists use to try to determine relationships. They examine how amino acid sequences have been determined for a number of proteins, and how scientists can make inferences about DNA based on the amino...

Eighth graders investigate chemical reactions to produce polymers. In this polymers lesson plan, 8th graders experiment with sodium silicate and ethyl alcohol to make a polymer. They also experiment with borax and glue to make a polymer....

Students explore electricity. In this Physics lesson, students investigate the origin of static electricity. Students compare static electricity to current electricity.

Fifth graders explore electromagnetic waves and light. In this light instructional activity, 5th graders draw the parts of a wave of the electromagnetic spectrum. They compare a flashlight to a laser to see how the light looks when...

Third graders discuss types of transportation. In this transportation lesson, 3rd graders discuss common ways people get around and the effect of electric energy on our society. They write a paragraph about different kinds of...

Students observe a planaria without a microscope and with a stereoscopic microscope. They draw the planaria and describe its motion and eating habits. Students research planarias various body systems and behavior. They design an...

Students find moles and molecules used when a candle burns. In this moles and molecules lesson plan, students calculate the initial mass of a candle and the mass of a candle after it burns for 3 minutes. They calculate the mass lost when...

For this mixtures worksheet, students experiment with different amounts of solutes and solvents to make solutions. They observe color changes and look for chemical and physical changes in the test tubes. Students answer 5 questions and...

In this ionic and covalent compound worksheet, students investigate the properties of three unknown substances in order to determine if they are ionic or covalent compounds. They write conclusions about their results.

In this groundwater pollution worksheet, students use a piece of bread to represent the earth, food coloring to represent contaminants in the ground and water to simulate the movement of pollutants with water through the ground. Students...

In this porosity and permeability worksheet, students experiment with different types of soils such as sand, gravel, pebbled and rocks. They put each soil type in a beaker and pour water in being sure to measure the amount of water they...

Students are introduced to electricity. In this electricity lesson, students listen to the book Switch on, Switch off  by Melvin Berger and discuss the use of electricity in light switches. They create a picture of an atom using pom...

Second graders look at different types of energy. In this energy lesson, 2nd graders define energy and the difference between kinetic and potential energy. They see examples with falling books and a slinky.
