Schoolyard Field Study
Introduction It’s the end of the school year. The weather is nice and your students are cranky. Some of the standardized tests are behind you, but you still have a week or so of school left. How can you make the most of this time while allowing your students to enjoy the outdoors? This activity […]
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 […]
Hands-On with Photosynthesis and Cellular Respiration
Photosynthesis is a topic that many students need help understanding. Using a hands-on experiment to demonstrate the process helps reinforce the concepts with students, especially your kinesthetic learns. Combining the lab with images and video found on the Internet targets your audio and visual learners as well. Below are simple activities that use Elodea to help teach […]
