Biology learners read about selective breeding in chickens and how it has produced high-yield meat specimens and rapid egg-layers. The unpleasant effects of artificial selection are explored, as well as options to supporting this...

Students investigate the properties of cell membranes by isolating the membrane surrounding chicken eggs. They set up an experiment by placing eggs in a vinegar solution for three days. A powerpoint lecture emphasizes the structure of...

Students share their science expertise with elementary students in a conference format. Elementary students rotate through sessions of different science disciplines (Biology, Earth Science, Physics, Chemistry, Computers).

Students graph data on fetal and infant mortality rates collected by the Centers for Disease Control and Prevention. They identify trends in the data and propose potential causes for the trends.

Ninth graders complete a unit of lessons on ecosystems, organism interactions, and energy flow. They create a key for known species of fish, diagram the movement of energy through an ecosystem, and create and present food chains and food...

Students explore digestion/nutrition and utilize scientific investigation skills. They complete meal logs for several days and graph their results. After analyzing their data, they write formal lab reports.

Students analyze data taken from proteomic experiments. In this biology lesson plan, students explain the importance of bioinformatics tools in the study of proteins. They evaluate scientific results using math and computer software.

Students choose a question from a given list and develop an investigation about it. In this biology lesson plan, students analyze bacterial growth by carrying out a guided experiment. They present their findings in class.

Learners participate in several activities on seed exploration. In this biology lesson, students classify seeds according to their dispersal method. They explain the different adaptations plant have to disperse their seeds.

Students use video and Internet components, to gain an understanding of non-native invasive plants and animals and the ecological and monetary problems they cause.

Students compare mitosis and meiosis with regard to chromosome number in parent cells versus daughter cells, types of cells produced, total number of cells produced, and the number of divisions. In groups, identify and differentiate the...

Learners are guided through the Scientific Method to perform observations about the pupa stage of the monarch butterfly. The results of an experiment are used to make assumptions about growth and development.

Fourth graders design a classification system to categorize animate and inanimate objects. They discuss the advantages of grouping things as they classify buttons, leaves, shells.

Students 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 acid...

Students compare and contrast classification systems used throughout the world. They also examine the importance of preserving biological diversity.

Learners design, build, draw, or bake a creature of their choice and present to the class. They write a paper including the creature's habitat, method of getting energy, their creature as a producer or consumer, predator or prey species...

A slideshow that covers the all-important details related to basic human circulation. The reasoning for exchange of material methods is presented and then labeled diagrams of the main human transfer systems are shown, along with...

Students examine how the method of classification is used. In this sorting lesson students take a pre-test, classify organisms and complete a crossword puzzle.

Learners examine how plants are able to adapt to their ecosystem and the role that fire plays in changes through the years.  In this ecosystem instructional activity students complete several exercises focussing on plants and their...

How do different minerals affect the growth of plants? Budding botanists find out in a multi-week experiment that has them using solutions with specific mineral deficiencies. While there is a lot of preparation for the investigation,...

Pupils research a topic in the various fields of science that interests them. Using a computer, they type their information to use on their project and use a scanner to place pictures or articles in the document. They use the steps...

Students prepare successful wet mount slide of Elodea. They determine and identify environmental conditions that induce cytoplasmic streaming. They determine the positive aspects of cytoplasmic streaming. They illustrate knowledge and...

Students examine the characteristics of fungi. In this biology lesson, students investigate the factors needed for fungi growth. They collect data and observations and write a report about them.

Students use a light microscope to observe the organisms living in a sample of ocean or fresh water. Students create a drawing of the organisms that they observe. Students then discuss the different body plans of the organisms and the...
