A study of the geology of Mars should reveal answers to such questions as how Mars developed into the planet we see today and what accounts for the differences and similarities between Earth and Mars. Visitors to this site can learn about ancient magnetism recently discovered by the Mars Global Surveyor that suggests the planet was once more dynamic and Earth-like with a magnetic field shielding the surface from cosmic radiation. They can read about the importance of studying the age and composition of Martian rocks, particularly those rocks and minerals which might have been formed in the presence of water. This is part of NASA's presentation of four science goals for its Mars Exploration Program, a science-driven effort to discover whether Mars was, is, or can be, a habitable world.

Student pairs experience the iterative engineering design process as they design, build, test and improve catching devices to prevent a "naked" egg from breaking when dropped from increasing heights. To support their design work, they learn about materials properties, energy types and conservation of energy. Acting as engineering teams, during the activity and competition they are responsible for design and construction planning within project constraints, including making engineering modifications for improvement. They carefully consider material choices to balance potentially competing requirements (such as impact-absorbing and low-cost) in the design of their prototypes. They also experience a real-world transfer of energy as the elevated egg's gravitational potential energy turns into kinetic energy as it falls and further dissipates into other forms upon impact. Pre- and post-activity assessments and a scoring rubric are provided. The activity scales up to district or regional egg drop competition scale. As an alternative to a ladder, detailed instructions are provided for creating a 10-foot-tall egg dropper rig.

Given an assortment of unknown metals to identify, student pairs consider what unique intrinsic (aka intensive) metal properties (such as density, viscosity, boiling or melting point) could be tested. For the provided activity materials (copper, aluminum, zinc, iron or brass), density is the only property that can be measured so groups experimentally determine the density of the "mystery" metal objects. They devise an experimental procedure to measure mass and volume in order to calculate density. They calculate average density of all the pieces (also via the graphing method if computer tools area available). Then students analyze their own data compared to class data and perform error analysis. Through this inquiry-based activity, students design their own experiments, thus experiencing scientific investigation and experimentation first hand. A provided PowerPoint(TM) file and information sheet helps to introduce the five metals, including information on their history, properties and uses.

Through two lessons and four activities, students learn about nanotechnology, its extreme smallness, and its vast and growing applications in our world. Embedded within the unit is a broader introduction to the field of material science and engineering and its vital role in nanotechnology advancement. Engaging mini-lab activities on ferrofluids, quantum dots and gold nanoparticles introduce students to specific fields within nanoscience and help them understand key concepts as the basis for thinking about engineering and everyday applications that use next-generation technology nanotechnology.

STEM CAREERS, TECHNOLOGY & INNOVATION What can you do with the nanoscale? This video shows us all the possibilities of how operating at the nanoscale can open up a whole new world in the advancement of science and technology.
ABOUT THE SCIENCE The word nano is from the Greek word “Nanos”, which means dwarf. Nanoscience works on a scale 1000 times smaller than anything that can be seen with an optical microscope, which is the microscope you most likely use in your science classroom. Nanoscience is an fascinating study using physical science, chemistry, physics, biology, environmental science and engineering. The career opportunities are equally diverse. Nano is all about the very small things in life, the stuff beyond what your eyes can see. How small is small? One hair on your head is between 50,000 and 100,000 in diameter. The nanoscale is based on the nanometre, which is one billion times smaller than a meter. In fact, because nano is a prefix, it always means one billionth of the unit connected. A nanosecond is one billionth of a second, a nanogram is; you guessed it! One billionth of a gram. When working on the small scale of nano, new materials and devices are developed by manipulating individual atoms and molecules. By manipulating these small structures you can change the properties of the material creating new materials with many applications. Although nano is small it has the potential to make big impacts. By working with nanomaterial you could conquer global issues such as cleaning unsafe drinking water, detecting cancer, and building faster technologies.

Students apply the knowledge gained from the previous lessons and activities in this unit to write draft grant proposals to the U.S. National Institutes of Health outlining their ideas for proposed research using nanoparticles to protect against, detect or treat skin cancer. Through this exercise, students demonstrate their understanding of the environmental factors that contribute to skin cancer, the science and mathematics of UV radiation, the anatomy of human skin, current medical technology applications of nanotechnology and the societal importance of funding research in this area, as well as their communication skills in presenting plans for specific nanoscale research they would conduct using nanoparticles.

In this unit of study, students will research topics in nanotechnology and attempt to identify a mystery mixture of different powders using a scanning-electron microscope. This unit integrates nine STEM attributes and was developed as part of the South Metro-Salem STEM Partnership's Teacher Leadership Team. Any instructional materials are included within this unit of study.

Students learn about the biomedical use of nanoparticles in the detection and treatment of cancer, including the use of quantum dots and lasers that heat-activate nanoparticles. They also learn about electrophoresis a laboratory procedure that uses an electric field to move tiny particles through a channel in order to separate them by size. They complete an online virtual mini-lab, with accompanying worksheet, to better understand gel electrophoresis. This prepares them for the associated activity to write draft research proposals to use nanoparticles to protect against, detect or treat skin cancer.

Students are given a general overview of nanotechnology principles and applications, as well as nanomaterials engineering. Beginning with an introductory presentation, they learn about the nano-scale concept and a framework for the length scales involved in nanotechnology. Engineering applications are introduced and discussed. This prepares students to conduct the associated activity in which they relate the nano-length scale to everyday objects. At completion, students are able to identify nanotechnology applications and have a frame of reference for the second lesson of the unit.
