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....

Third graders are introduced to the topic of matter. As a class, they brainstorm what they already know about matter and its properties. After completing a worksheet, they participate in an experiment in which they observe matter in...

In this chemistry worksheet, students learn about matter, including atoms, electrons, protons, neutrons, compounds and chemical properties. They use this information to answer the 10 questions on the worksheet. The answers are on the...

Students examine significant innovations in surgery and reproductive health.  In this surgery lesson plan students view a video and answer the given questions. 

In this longer word worksheet, students review the chunking sound method for spelling longer words. Students then study a list of longer words and select four of them to write on the provided lines. Students also write a short sentence...

Students develop an understanding and appreciation of water purification techniques and their implications for health maintenance.

Students identify via slides prokaryotic and eukaryotic cells. They identify plant or animal cells from slides or pictures. Students are given the question of the day. They are asked which has a nucleus, a prokaryotic or eukaryotic...

Pupils explore and explain how moon snails eat and where the holes in clamshells come from and then draw conclusion from the data collected. They incorporate math and graphing skills to determine if there is a relationship to a clam's...

Second graders examine compost piles and what invertebrates help decompose the organic matter.  In this compost invertebrates lesson students collect invertebrates found in a compost pile and examine them. 

Fourth graders investigate riverbanks and oxbox ecosystem at the Truckee River. They observe the plants, animals, insects and water organisms located there. Students document water samples, flow and then categorize them in class. This...

Students investigate ecological systems and the multiple uses of the environment by studying the osprey population.

Students explore human senses. In this applied Science lesson, students utilize their senses to distinguish various objects. Students explain their descriptions.

Pupils observe and examine the life cycle of antlions, recording their observations of the live insects in a journal. They view an antlion on a video microscope, draw the body parts, and replicate their experiment at home.

In this science instructional activity, students investigate plants by first reading a paragraph of information. Students then choose a plant, illustrate and write about it.

In this kidneys worksheet, students review the structure and function of the kidneys in the human body. This worksheet has 18 fill in the blank statements.

Seventh graders use a pond to explore macroinvertebrates and other organisms. They use a dichotomous key to classify the organisms and maintain a journal recording their findings.

Students study about geologists and their job. They also study that rocks are made up of minerals and organic material by conducting an experiment where they create their own "granite" or "coal".

Students use a written key or illustrated key to identify fungi on plant leaves into its genus based on sexual or asexual reproduction, host range diversity, and host-parasite relationships.

Learners become familiar with real-world gathering of chemical data. The experience how the science is done: the nature of analysis, data collection, interpretation, and presentation. They study a nearby body of water for their experiment.

Students develop a greater awareness of the variety and amount of particulate matter in the air. They try to locate general sources of pollution for a specific area and develop some suggestions for improving air quality.

Students examine diversity on the planet and the differences within a species.  In this investigative lesson students complete a lab that allows students to better understand the relatedness between plants. 

Learners recognize slides of different fungi. They work in lab groups. Students view slides under the microscope, then draw and label the parts, magnification, and the organism. Learners discuss similarities between some fungi and...

Fourth graders watch the movements of the complex animal hidden inside the tiny barnacle shells. This lesson allows students to study the behavior, adaptation, and larval stage of the barnacle.

Students observe the embryological development in the zebrafish. Developmental hierarchy from three germ layers is studied in depth. Research is validated on the body plan of the embryo.
