Pupils prepare a slide of Paramecium cultures and observe (through a microscope) the organism's thin transparent membrane and what happens as they "feed" them stained yeast cells. They sketch the path the ingested yeast takes as it...

Students use scientific methods to investigate the concept of DNA. They observe the DNA of human cheek cells. This is done with the use of a lab experience. Students record their observations and reflect upon on how each organism is...

Young scholars participate in an experiment in which they transform an E. coli cell. They discover how the genetic make-up of the cell can be changed by added foreign DNA. They answer questions to complete the lab.

Students investigate techniques involved in extracting and isolating DNA. Students extract and observe onion DNA.

Students examine the relationship between leukocyte adhesion and migration in response to chemoattractants. They discuss sterile techniques, observe a demonstration using mock cell culture, and develop a procedure for studying the...

Fifth graders identify the role succession plays in the adaptation of our environment. Students identify pioneer and climax species and order habitats in succession. They recognize that different characteristics of species make them...

Students investigate the story "The Tiny Seed" by Eric Carle. This story is used to introduce the children to the concept that seeds change and grow into plants when conditions in the environment including temperature, light, water and...

Students develop an interactive diary to record bird seed consumption. In this habitat instructional activity, students predict and record the amount of birdseed eaten each week by birds.

Students analyze the factors affecting organisms in the pond ecosystem. In this environmental science activity, students perform an experiment to determine pH, nutrients and temperature of different pond sites. They present their result...

Students conduct an egg candling activity to show the life inside a fertile egg. Students discuss the needs the egg has of the hen, as well as similarities and differences between plants and animals. Students complete a life cycle wheel...

Seventh graders are engaged in a activity that covers the concept of meiosis with the intention of covered sexual reproduction. They cover the concept of genetic traits and how they are transmitted over generations with or without...

Young scholars perform an experiment to compare the sensitivity of the various developmental stages of Red Flour Beetles to ultraviolet radiation. Larvae, pupae and adult beetles are exposed to a source of UV-B radiation. In groups,...

Here is a lesson which incorporates ingenious hands-on activities that simulate how many animals use camouflage as a survival technique. This lesson clearly outlines how to implement the activities and discussion sessions found in it....

Students are introduced to the realm of social insects, their role in the environment and the biological features that make them unique.

Students examine a still-life painting. They discuss the observation of nature by scientists and artists and explore the symbolism of biological life cycles depicted in a painting.

Students use the reptile section of the Digital Atlas of Idaho. They make a dichotomous key and decide on what defining characteristics they can use to distinguish between species. They hone their observation skills and recognize...

Students are using a paper chromatography study that is suitable for introductory biology. The absorption spectra studies and gel electrophoresis studies are appropriate for students who have complete both introductory biology and...

High schoolers make and use observations of Laetoli footprints to provide clues to life in the past. They collect and analyze data to study the relationship between foot length and body height.

Seventh graders perform a dissection on a mussels and label their internal organs. In groups, they compare and contrast the mussels structure to those of human beings. They also review the functions that are necessary for survival and...

Students "take a trip" to the Greater Antilles to observethe Anolis lizards. They study the body structures and habitat of different species, then plot this data on a map to look for patterns in their distribution. From the patterns they...

Students make a chart of the life cycle of the painted lady butterflies that the class observes over a period of several days.

Young scholars engage in research about the hantavirus. They use a variety of resources to obtain information. Students distinguish the differences between hantavirus pulmonary syndrome, hantavirus transmission, and hantavirus prevention.

Students investigate the concept of crop farming. They plant small fields to test different theories of agriculture. Students keep care over the fields, including pest and weed control. Students make and record daily observations to...

Students use common materials to construct a working model of the water cycle. They then observe and explain evaporation, condensation, precipitation and percolation as aspects of a continuing cycle. Students also complete worksheets and...
