Labs & Activities

Abuse-a-Cyst- University of Utah

Brine shrimp populations survive in some of the harshest environments. Subject brine shrimp cysts to extreme conditions then try to hatch them to see just how tough they are! Downloads Abuse a Cyst Lab (University of Utah)

Acid Rain Lab- Katherine Betrus Derrico

Students will design and conduct an experiment to test the effect of acid rain on the germination of seeds. They will utilize the data from their experiment to explain their conclusions, and also read a passage on acid rain. Downloads Acid Rain Lab Rubric (Katherine Betrus Derrico) Acid Rain Lab… read more

Battle-jar Galactica- Matt Downing

In this investigation students will study the types of bacteria that grow during the formation of sauerkraut, identify some characteristics of each, as well as research the type of respiratory pathway used by the organisms to break down the cabbage to get their energy. Downloads pH Questions (Matt Downing) Bacteria… read more

Becoming a Plant

Students will plant seeds at various depths in the soil and make observations after seedlings emerge. Based on their observations, students will decide what measurements could be made. They will make these measurements and look for an explanation for differences in their measurements. They will write a hypothesis that describes… read more

Biological Shapes

Remember the old salad dressing commercial tag line “…because oil and vinegar don’t mix!” Water has that same love/hate relationship with many other molecules. Through this series of lessons, students will learn about the properties that make other molecules “love” or “hate” water. They will also begin to build a… read more

Biomagnification Lab- Todd Shuskey

This lab demonstrates how contaminants can accumulate in organisms within a food web by using paper cutouts and M&M®s candies to simulate fish, osprey, and DDT. Students can see how the contamination levels increase as the trophic level increases. Downloads Biomagnification Lab (Todd Shuskey) Biomag Lab Pics (Todd Shuskey) Biomag… read more

Blood Vessel Physiology

This lab investigates the physical mechanisms by which our blood vessels function in allowing the circulatory system to do its job. Blood vessels are not simply rigid tubes that conduct blood to our tissues like copper pipes carrying water to our houses, nor are they infinitely extensible balloons that can… read more

Bottle Ecosystem- Tim Downs

The objective of this lab is to put together a suitable habitat (ecosystem) that will allow one or two guppies to survive to the end of the school year and beyond. Students will make observations of their ecosystems for the three weeks. The ecosystem in this experiment will be closed,… read more

Bouquet of Flowers

This series of four different lab activities all relate to flower reproduction. They have been designed to relate to each other and to stand alone. Name that Pollinator focuses on adaptations for successful pollination. Both pollen and pollen vectors are examined. Observing, data gathering, making measurements through the microscope, and… read more

Bovine Uterus Dissection

The instructor will dissect an early to mid-pregnant bovine reproductive tract. Data on crown rump length and fetal mass can then be collected for use with CIBT’s Fetal Development Lab. Some appreciation of the form and function of the various organs should be developed by students. This exercise will also… read more

Building Blocks of Life

The shape of a protein determines its function. In this lab, students will be given a hypothetical DNA sequence for part of an enzyme. Using the Universal Genetic Code, they will then determine the amino acid sequence coded for by the DNA. Students will examine a “substrate” and predict the… read more

Case of the Missing Diamond Maker

Students will learn about some of the techniques of forensic science. They will use fingerprinting, chromatography, and chemistry to gather and analyze evidence left behind at a crime scene. Students will exercise deductive reasoning to evaluate the evidence and determine the criminal’s identity. CIBT has prepared a Missing Diamond Maker… read more

Catalase

The structure and function of enzymes is a central theme in cellular and molecular biology. In this laboratory exercise, a crude cell extract is prepared from potatoes. Activity of the enzyme, catalase [which catalyzes the reaction 2H2O2(l) → 2H2O(l) + O2(g)], is then studied using a simple assay for O2. To… read more

Comparative Skulls

What can a skull tell you? A lot! If you look at a skull for clues about its origin, not only can you identify what species it might be from, but you can learn many details about the original animal. In this lab, students will determine what clues to analyze in… read more

Comparing Aquatic Communities

Teams of students measure physical and chemical characteristics of different sites in streams and/or ponds and collect benthic invertebrate organisms. They interpret patterns in the structure of the biological community at each site in light of the abiotic (physical  and chemical) and biotic nature of the environment. Downloads Comparing Aquatic… read more
