Future chemists practice laboratory techniques by creating a monochloramine solution. The objectives are to use of dilution, 9concentration, and measurement skills and to prepare a solution that will be used in a water treatment...

Anytime you make concepts clear with role playing or hands-on experience, it's a win for the whole class. Ping-Pong balls are used to represent carbon in a carbon cycle role-play activity. In small groups, children first discuss what...

Learners explore atomic measurement in the first activity in a series of 36. Through readings, activities, and questions, classes review standard SI units, learn about Avogadro's constant, and use it to help them calculate moles. They...

Fourth graders observe brine shrimp over several days. They create drawings showing the growth and development of the shrimp. They research web sites to find out where brine shrimp fit on the food chain and what makes the shrimp unique.

Students set up a stream table, observe erosion, and record data on where various sizes of sediments settle. They draw conclusions as to what kind of sedimentary rock form in what locations.

Students use Koch's Postulates to determine that a specific organism is the root cause of a specific disease and identify what Koch's Postulates are within a protocol. They describe symptoms and signs of diseased fruit and isolate fungal...

Students investigate protozoa. In this protozoa lesson, students identify and classify different types of protozoa using different ecological samples and protozoa charts.

Students study cellular structures and functions.  In this cell function lesson students participate in a class discussion then make a drawing of the cell they are discussing. 

Students use this laboratory procedure to outline the mechanism by which salivary glands are removed and prepared so that the polytene chromosomes may be observed.Drosophila virilis is used instead of Drosophila melanogaster because D....

High schoolers analyze and record major events that occur in the development of Medaka fish eggs from fertilization to hatching. In small group, students describe the processes involved, creating a timeline of the major events in the...

Learners witness various stages of mitosis through preparing onion root tip slides. With teacher guidance, they learn a great deal through the hands-on process of preparing the slides themselves.

StudentsMatch the vocabulary terms in column A with the definitions in column B. Write the letter of the definition in column B in the space next to the terms in column A. Afterwhcich, students Write short answers or fill in the blank to...

Eighth graders, after creating a Venn Diagram comparing/contrasting animal and plant cells, writing ten similes describing cell types, or drawing a colored diagram of a cell, list cell types as well as describe and label cell parts. They...

Students relate heart rate and development to environmental conditions through experiment. In cooperative groups, students record the heart rate in developing zebra fish. Groups create a standard curve to predict the temperature at...

In this reproductive system worksheet, students compare specimens of rat ovaries and testes. They complete 5 short answer pre-lab questions, follow an 11 step procedure and answer 5 analysis questions.

Learners describe the history of materials. They use the kinetic (particle) theory to explain changes of state in matter and trace the flow of heat during changes of state and chemical changes.

In this biology instructional activity, students complete 28 short answer questions on fungi. They color and label the different parts of a hyphae.

Middle schoolers research the affects that particulate matter has on the quality of our air and our health. Students analyze a streaming video on air pollution and complete an internet research assignment to find ways to reduce...

Learners take a closer look at human skin. In this biology lesson plan, students describe the four functions of the skin as they complete a hands-on activity.

Students create their own environment. In this environmental protection lesson, students pretend they are the owners of a tropical island. They create jobs for the citizens and develop the island as a model environment.

Students investigate different types and their parts. They differentiate prokaryote and eukaryote cells and create a venn diagram displaying differences or similarities. Students write ten similes related to the cells and parts of them.

Students identify producers and consumers from marine ecosystems and describe the balance among them in the environments. After constructing a food chain from a marine ecosystem, they examine human activities that can upset the balance...

Students compare water quality of different sources. They test water samples for odor, phosphates, pH, bacteria, and dissolved solids. they fill out a data table and answer questions about their findings.
