Let the lab be a catalyst to learn about enzymes. Scholars create alginate beads filled with yeast. As part of an investigation into enzymes, they see how these beads provide a catalyst to the reaction of glucose into ethanol.

Capillary action is the frugal chemist's dream ... the less liquid used, the more tests they can run! Learners experiment with the best design to maximize the benefits of capillary action. Using a liquid sample, they design a capillary...

Scientists found fossils of plants more than 420 million years old—but plants existed for up to 100 million years prior to these fossils. Learn about the importance of plants to the entire planet. Viewing a presentation helps scholars...

How is the Earth's weather created? Middle schoolers will explain how the Sun's energy is transformed into different forms. They will perform mathematical calculations of volume, mass, and temperature. They they will explain the...

Introduce ecology classes to biodiversity and interdependence in ecosystems with a PowerPoint presentation. Then, they get up-close and personal with the invertebrate world by collecting insects, classifying them, and graphing their...

What can one learn about a planet based on a small surface sample? Learners will explore artifacts from a mystery planet and see what they can determine about the planet based on the evidence in front of them. 

Take your class of youngsters on a prehistoric adventure with this four-lesson series on dinosaurs. Accompanying the Meet the Dinosaurs books by Don Lessem, these lessons engage children in writing their own dinosaur books,...

What makes up a habitat? Use this resource to engage first graders in the exploration of desert, wetland, forest, and ocean habitats. Youngsters classify plants and animals into the four distinct habitats through drawings and cutting and...

Can scientists really predict genetic outcomes or are they simply making a lucky guess? Scholars first learn about Gregor Mendel and how to make Punnett squares. Then they extract DNA from a strawberry in a lab with included conclusion...

Sixth graders will simulate the spread of a virus such as HIV through a population by "sharing" (but not drinking) the water in a plastic cup with several classmates. Although invisible, the water in a few of the cups will already be...

Students observe cytoplasmic streaming in Nitella cells. They examine the conduction of a wave of depolarization across other membranes, such as the axons of neurons. Students predict the effects of sending a small electric current...

In this mollusk and segmented worm activity, students will review 7 vocabulary words associated with these groups of organisms by completing a crossword puzzle.

Students manipulate flies, examine their external anatomy, begin a fly journal and make cultures of wild type flies.

Students collect their own flies and construct crosses, then compare them to the data from lesson two.

Learners investigate the effects of an acid and a base on the structure of milk protein. They observe the changes to droplets of milk when adding ammonia and lemon juice and relate the changes to old, curdled milk. An extension using...

Students examine fire flies. They measure the frequency of light stimulus used by communicating fire flies. Students explore the concept of organisms using light to communicate. Students film the fire flies and quantify the duration...

Student perform an experiment in which they determine the velocity of ion flow in an electrotonic potential and compare it to the velocity of action potentials. They record and analyze their results.

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.

Pupils explore basic bacteriological techniques. They investigate cell to cell communication and become aware of the environmental and evolutionary implications of this communication.

Students discuss the antibiotic resistance of bacteria. They design an experiment to test the resistance of different strands of E. coli. They answer discussion questions to end the lesson.

Students, working in cooperative groups, extract very impure samples of DNA from a number of tissue samples. They determine how the samples can be preserved and how they are similar.
