Plant and Animal Tissues

Developed by: Matt Keirle, Ph.D., Assistant Professor, State College of Florida

In this lab activity, students will use a compound microscope to examine a few simple plant and animal tissues and explore the idea of different cell types that specialize in their form and function.

Estimating the Time Needed for Mitosis

Developed by: Matt Keirle, Ph.D., Assistant Professor, State College of Florida

In this lab, students will learn the phases of mitosis and determine the approximate time it takes for plant and animal cells to pass through each of the four stages of mitosis. They do this by counting the number of onion root tip cells and whitefish blastula cells in each of the four phases of mitosis and in interphase. It also includes discussion questions that can be used to illustrate the concept with out completing the activities.

Properties of Macromolecules

Developed by: Matt Keirle, Ph.D., Assistant Professor, State College of Florida

This lab explores different analytical tests that are used to detect the presence of specific macromolecule classes based on their properties. Students will also have a chance to measure your own body mass index taking advantage of the bioelectrical impedance properties of body fat and an opportunity to extract their own DNA.
