This activity helps students understand how a motor in a LEGO MINDSTORMS(TM) NXT robot uses electricity produced by the battery to move a robot to do useful work in the form of throwing a ball. Students relate the concepts of electricity and battery to the movement of the LEGO NXT motor and connected links.

This site is for the young writer who is itching to write a novel … in 30 days. Lesson plans from prewriting to publishing help kids to develop and fine-tune their writing skills. This is a great resource for students who are up for using their imagination to create another world or simply tell their story. From lower elementary to high school.

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.

In this lesson, students practice a way to communicate without words by using a glyph. They create a name card using information about themselves. Students also interpret glyphs made by others.

Students demonstrate their letter/sound knowledge by working with name cards and sharing observations about their classmatesŐ names, giving teachers an opportunity to assess knowledge in a meaningful context.

Students name unnamed chapters in a novel they are reading. They discuss possible chapter names, considering accuracy, word choice, and connotation, before settling on a choice.

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.

Students explore naming conventions in digital and non-digital settings then choose and explain specific names and profiles to represent themselves online.

The goal of this task is to show that when the whole is not specified, which fraction is being represented is left ambiguous.

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 will investigate the properties of matter too small to see, as well as how it behaves when present in different quantities. Students will design a procedure to measure the thickness of a thin film of oil on the surface of water.

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.

Using Beloved as a model of a work with multiple narrative perspectives, students use a visualizing activity and close reading to consider ways in which subjective values shape contradictory representations.

Through a partnership with Google Arts & Culture, an online exhibit shows the history of The Nutcracker ballet in numerous slides and photos, including a video explaining how a dancing horse costume is brought to life onstage.
Many other Canadian museums and galleries that lack interactive online exhibits still have photos from their collections available online for hours of perusing, such as the National Gallery of Canada and Gardiner Museum.
Google Arts & Culture also has partnered with hundreds of museums across the world to allow extra exhibits and gallery walkthrough online. Their top 10 list of museums that can be explored digitally includes numerous cultural wonders, such as the Uffizi Gallery in Florence, Musee d’Orsay in Paris, the National Museum of Modern and Contemporary Art in Seoul, and the Pergamon Museum in Berlin.
