This activity uses a mix of multimedia resources and hands-on activities to support a storyline of investigation into melting sea and land ice.
Insert channels in a membrane and see what happens. See how different types of channels allow particles to move through the membrane.

In this activity from NOAA's Okeanos Explorer Education Materials Collection, learners investigate how methane hydrates might have been involved with the Cambrian explosion.
The students will listen to and discuss books about butterflies and the migration of monarch butterflies to Mexico in order to integrate science, social studies, and language arts.
The activity is a field trip to Minnehaha Falls where students will observe and record their findings in a science notebook.
This activity is a classroom guided inquiry lesson where the student will sort, identify, and classify Minnesota fish.
This activity is a classroom and field investigation where students will group Minnsota fish families and create their own pop can fishing rods.
In this biology field experience, students will explore trees of Minnesota. Working in cooperative groups, students will discover biodiversity of trees and determine populations of tree species through observation and use of dichotomous keys.
Discover what controls how fast tiny molecular motors in our body pull through a single strand of DNA. How hard can the motor pull in a tug of war with the optical tweezers? Discover what helps it pull harder. Do all molecular motors behave the same?
Molecular Workbench is a FREE and OPEN SOURCE, downloadable software utilizing Visual, Interactive Simulations for Teaching & Learning Science.
A typical MW module is a comprehensive learning package consisting of a series of scaffolded pages that contain text, simulations, tools, controls, graphs, navigation links, and embedded assessments. The user interfaces of simulations in MW can be customized for students of different levels (grades 6-16). This unique feature enables it to support a wide range of instructional strategies such as inquiry-based, discovery-based, and problem-based learning. (For Windows, OSX. Must have Java)
Students will predict bond polarity using electron negativity values; indicate polarity with a polar arrow or partial charges; rank bonds in order of polarity; and predict molecular polarity using bond polarity and molecular shape.
A lab activity that develops methods other than sight to collect information.
Students will learn to identify 3 to 4 birds by their song.
This course focuses on the latest scientific developments and discoveries in the field of nanomechanics, the study of forces and motion on extremely tiny (10-9 m) areas of synthetic and biological materials and structures. At this level, mechanical properties are intimately related to chemistry, physics, and quantum mechanics. Most lectures will consist of a theoretical component that will then be compared to recent experimental data (case studies) in the literature. The course begins with a series of introductory lectures that describes the normal and lateral forces acting at the atomic scale. The following discussions include experimental techniques in high resolution force spectroscopy, atomistic aspects of adhesion, nanoindentation, molecular details of fracture, chemical force microscopy, elasticity of single macromolecular chains, intermolecular interactions in polymers, dynamic force spectroscopy, biomolecular bond strength measurements, and molecular motors.
Explore natural selection by controlling the environment and causing mutations in bunnies.
Roles of neural plasticity in learning and memory and in development of invertebrates and mammals. An in-depth critical analysis of current literature of molecular, cellular, genetic, electrophysiological, and behavioral studies. Discussion of original papers supplemented by introductory lectures.
Lectures and discussions explore the clinical, behavioral, and molecular aspects of brain aging processes in humans. Topics include: loss of memory and other cognitive abilitites in normal aging; neurodegenerative conditions such as Parkinson's and Alzheimer's diseases. Based on lectures, readings taken from the primary literature, and discussions. Students are expected to present topics based on their readings. One written mid-term test and one final examination. Alternate years.
Stimulate a neuron and monitor what happens. Pause, rewind, and move forward in time in order to observe the ions as they move across the neuron membrane.
Molecular Workbench (MW) is powerful, award-winning software that provides visual, interactive computational experiments for teaching and learning science. These simulations are HTML5 and work well on non-java based platforms.
