Labs & Activities

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

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

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

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

Diffusion

This lab uses two different sizes of dialysis tubing to represent cellular and organelle membranes. Students design experiments in which they place solutions of iodine, starch, and glucose on different sides of a membrane. The movement of these materials is monitored with the use of indicator solutions. Students are given… read more

Edible Earth Parfaits- Groundwater Foundation

This activity uses soda, ice cream, sprinkles, colored sugars, and food coloring to represent the layers of Earth and aquifers under the surface. Students are instructed to “drill a well” with a straw and “pump the well” by sucking on the straw, as they watch the decline in the water… read more

Phoot Lab

In this lab students will investigate the application of physical principles to a living organism. Students will analyze the foot and its function as a machine by applying lever mechanics to the “walking” foot. Analysis will incorporate anatomical terms for some of the muscles and bones involved in plantigrade motion…. read more

Primary Productivity Lab- modified by Sean McGlynn

Students will use LaMotte Test Kits to determine the concentration of dissolved oxygen (DO) in various water samples. The process involves adding some chemicals to the water to “fix” the free oxygen (O2). Once the O2 is fixed, they will add an acid powder, some starch, and titrate to determine… read more

Shake and Break: An Earthquake Simulation

An earthquake simulator, or seismic table is constructed and then used to test the structural soundness of several types of student built houses. Several different construction materials are used to demonstrate what type best survives an earthquake. Two different geological foundations, bedrock and water-saturated sand, are tested to show the… read more
