NSDL teaching resources related to “part”

This site consists of a series of pages, each depicting and describing an object(s) on a different order of magnitude. There are 42 pages of this in all, for 42 powers of ten, starting with quarks (10^-14 meters) and ending with ‘near the limit of our knowledge’ (10^25 meters). The pictures ‘zoom out,’ with the quarks being part of a proton being part of a nucleus, and so on. There are short descriptions for each of the physics-related objects (i.e. quarks, atoms, clusters) and some of the locations, as well as links to more extensive descriptions. Also included is a page on units and scales.

Tutorial

In this lesson, students will view salt under varied magnifications and begin to construct the understanding that materials may be composed of parts that are too small to be seen without magnification. They will observe salt with the naked eye, and then under a hand lens, microscope, and the electron microscope (the electron image is via the Internet). In order to complete this lesson, it is important that students have previous experience working with hand lenses and microscopes.

Lesson/Lesson Plan

In this activity, learners examine body parts (including skin, scales, and skulls) from fish, mammals and reptiles. Questions are provided to help encourage learner investigations. Several activities are described, including object identification (what animal and what part of the animal?), free sorting of the objects, and a discussion of similarities, differences, and protective functions of the animal parts. It’s written for use as a cart demo in a museum or aquarium, but could be done anywhere animal body parts are available.

Students learn about the formation of craters and their structure, exploring the effects of mass, velocity and size on the resulting crater. The parts of a crater are also identified.
