This Classroom Connectors lesson plan teaches students about ocean movements such as currents, tides, and waves. This includes types of currents, Northern and Southern Hemisphere currents, differences between salt and fresh water, trade winds, and tsunamis. The site provides goals, objectives, an outline, time required, materials, activities, and closure ideas for the lesson. The Classroom Connectors address content with an activity approach while incorporating themes necessary to raise the activity to a higher cognition level.
This article from Technology Review discusses the new technology of controlling insects using cybernetic implants. It includes several pictures of a beetle with implanted equipment that researchers use to direct the movements of the beetle.
This peer-reviewed article from BioScience journal is the role of monoamines in animal behaviors.Animals possess a rich repertoire of behaviors, each generated by the orchestrated activity of assemblies of neurons. Neuromodulators, and particularly monoamines, have been found to play a role in the recruitment of such assemblies. The role of specific monoamines in the modulation of behavior has been particularly well studied using invertebrate animals as models.
This classroom-tested instructional unit was developed to build interest and excitement about the practice of science by real people in real laboratories. It takes learners on a journey to understand how a good experiment is designed, how to recognize bias and error, how to perform an investigation into the natural world, and how to clearly communicate about the findings. It is divided into 15 sections, many of which can be parsed out separately.
This web page is a NASA press release that discusses the finding of magnetic stripes on the surface of Mars and its relation to plate tectonics, e.g. past movement of the Martian crust. Links to other information on Mars are also included.
If a sailboat is stranded because there is no wind, is it possible to set up a fan on deck and blow wind into the sail to make the boat move? In this activity, learners explore this classic physics question by using simple materials to build a low-friction cart with a removable motor and a removable sail. Learners will observe the behavior of their cart and see Newton’s Laws in action.
This article is a Why Files short piece that examines the movement of Antarctic ice sheets into the ocean. Both East and West Antarctic ice sheets are rapidly moving into the Southern Ocean, which could raise sea level by 70 meters causing massive problems for populated coastal areas around the world. This article looks at the evidence for these events, and what it could mean for coastal regions.
Ian McHarg (1920–2001) was one of the true pioneers of the environmental movement. In his 1969 landmark book, Design With Nature, McHarg spelled out the need for urban planners to consider an environmentally conscious approach to land use, and provided a new method for evaluating and implementing it.
