Students gather […]
Modeling Mitosis and Meiosis
Introduction Have student groups use sock “chromosomes” and string to model mitosis and meiosis. These 2 simple activities take approximately 30 min to complete. Discussion questions and answers are provided so that you can assess student understanding of each type of cell division. Next Generation Science Standards Life Science The Cell The Molecular Basis of […]
The Pressure’s On: Creating and Using Models of Body Systems
Workshop Resources Life Science 6-12 Middle / High School Learn exciting and engaging ways to teach structure and function within body systems. Use hands-on labs to help students understand kidney function and interactions between the excretory system and cardiovascular system. Set up experiments, collect data, analyze results, and create models to build toward understanding the […]
Just Passing Through
In-Booth Demonstration Life Science 9-12 High School / College Cell membranes are semipermeable, meaning that only certain substances, based on the molecule’s size and electric charge, can pass through. Molecules passively move from areas of high concentration to areas of low concentration. Starch, which is a large molecule that cannot pass through most membranes, can […]
Diffusion—Molecules on the Move
Diffusion: Molecules on the Move Dialysis tubing is an excellent way to simulate the cell membrane’s selective permeability. In this experiment, sealed dialysis tubing containing a test solution of albumin, glucose, sodium chloride, and starch is placed in a cup of distilled water. After 30 to 45 minutes, the tubing is removed from the cup […]
Osmosis Eggsperiment
Introduction 2-3 students per group Prep: 15 minutes Class: 15-45 minutes over 3 days Subject: Physiology Grade: 6-12 Water passes into and out of cells by a special type of diffusion called osmosis. Osmosis is the diffusion of water molecules across a selectively permeable membrane from an area of higher water concentration to an area of […]
Developing and Analyzing Urine Samples as a Model of Kidney Function
Abnormal urine composition often indicates disease or infection. Diabetes is often diagnosed after a patient has a positive test for glucose in the urine. Diabetes is the result of an inability to absorb glucose from the blood. The body compensates for these elevated blood glucose levels by filtering the glucose out through the kidneys; the excess glucose exits the body through the urine.
Urinary System
Urinary System Introduce Urinary System Unless they’re on a long car trip or cross-country flight, most people don’t give their urinary system a second thought. They should, though. A fully functioning urinary system is necessary for an active, healthy life. The system filters extra water and waste products, such as salts and proteins, from the […]
