A 2-D map is a great guide here on Earth—and virtually worthless for finding your way around in outer space. Take a 3-D look at mapping our solar system and universe. This Moveable Museum article, available as a printable PDF file, looks at how astronomers use data to create 3-D models of the universe. Explore these concepts further using the recommended resources mentioned in this reading selection.

Coders use the start on green flag block to create a silly dance party using motion blocks. The purpose of this project is to introduce young coders to adding sprites in code and triggering algorithms with the green flag in ScratchJr.

This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:

"3D-printed with microscale precision, these tiny architectural marvels could be the key to making high-temperature ceramics less vulnerable to fracture. The implications could span across the numerous areas these materials are used, from aerospace to tissue engineering. The blueprint for these hardy structures is reported in the Journal of Materials Research Volume 33, Issue No. 3, earning honors as the 2018 JMR Paper of the Year. Researchers built the miniature trusses layer by layer using a technique called projection microstereolithography. In this process, a UV-light pattern is scanned across a polymer bath composed of photo-active ceramic building blocks. The silicon-based polymer solidifies at every point traced by the UV beam. Subsequent heating in a high-temperature furnace activates the polymer structures, baking off volatile organics, to produce silicon oxycarbide structures. The team then put these structures to the test..."

"When modern 3D printing was invented in the early 1980s, few could have predicted the influence it has today. At no other time in history has it been this easy to transform a sketch into the real thing. And while that feat has proven immensely useful for constructing complex machines, it is unlikely more meaningful anywhere else today than in the field of biomedicine. With the ability to churn out standard or custom prosthetics, devices, and even test models, the 3D printing of biomaterials is revolutionizing medical care. One of the greatest conveniences afforded by biomedical 3D printing is the ability to manufacture parts on demand. Common load-bearing prosthetics, such as those for knee or hip replacements, no longer have to be built in bulk and benched before use. Virtually stored print files can be called upon and processed into parts as soon as they are needed in the clinic, with the printing material and method suited to the part’s function and placement..."

In this lesson, students expand their understanding of solid waste management to include the idea of 3RC (reduce, reuse, recycle and compost). They will look at the effects of packaging decisions (reducing) and learn about engineering advancements in packaging materials and solid waste management. Also, they will observe biodegradation in a model landfill (composting).

Mrs. Rowhani's third graders learn about matter and energy by building a Spout bot with Khan Academy. Special thanks to: Santa Rita's volunteer parents, Kami Thordarson, Karen Wilson and of course Laleh Rowhani the class teacher. Created by Karl Wendt.

This is an extension activity after discussing cancer or lead into discussing about student choices. Essential QuestionsStudents will be able to to describe behaviors lead to skin cancer and how can it be prevented.Students will be able to explain the risk and reward behaviors.  

The student wil read the material, then take a quiz with questions from the material.

As an activity related to FOSS unit Magnetism and Electricity, 4th grade science students use a computer download to explore electrical circuits and to generate illustrations of electrical circuits for physical models built in class

American Expeditionary Forces recruiting poster showing scenes in France like those new recruits can expect to see upon arrival in France with the A.E.F. Poster caption: Do you want to see Paris, too? Then ask the Army Recruiting Officer at once about your chance to be one of the 50,000 lucky men to see France and the Rhine, and the battlefields of Europe - free. Tourists are clamoring for a chance to pay for this privilege. Don't delay - See the Army Recruiting Officer to-day. Poster caption: Here's your chance! 50,000 men are now enlisting for service in the A.E.F. to see France, and the Rhine with its historic castles and forts. Infantry, cavalry, field artillery, engineers, and medical department open. Ask the Army Recruiting Officer about educational opportunities in the A.E.F. Photo illustrations provided by Keystone View Company and courtesy of Collier's "The National Weekly." Two posters printed on one sheet, uncut, mounted on linen. Title from item.
