Commercial fishing nets often trap "unprofitable" animals in the process of catching target species. In this activity, students experience the difficulty that fishermen experience while trying to isolate a target species when a variety of sea animals are found in the area of interest. Then the class discusses the large magnitude of this problem. Students practice data acquisition and analysis skills by collecting data and processing it to deduce trends on target species distribution. They conclude by discussing how bycatch impacts their lives and whether or not it is an important environmental issue that needs attention. As an extension, students use their creativity and innovative skills to design nets or other methods, theoretically and/or through hands-on prototyping, that fisherman could use to help avoid bycatch.

Bycatch, the unintended capture of animals in commercial fishing gear, is a hot topic in marine conservation today. The surprisingly high level of bycatch about 25% of the entire global catch is responsible for the decline of hundreds of thousands of dolphins, whales, porpoises, seabirds and sea turtles each year. Through this curricular unit, students analyze the significance of bycatch in the global ecosystem and propose solutions to help reduce bycatch. They become familiar with current attempts to reduce the fishing mortality of these animals. Through the associated activities, the challenges faced today are reinforced and students are stimulated to brainstorm about possible engineering designs or policy changes that could reduce the magnitude of bycatch.

Students will observe dance movements depicted in a drawing and a painting. Partners will use simple lines to draw their partner's movements and paint dance costumes on the figures using various brushstrokes. Students will write a persuasive speech to the school superintendent explaining why they believe dance should be a regular part of the curriculum. They will then model dance movements for classmates in teams of four and recite their persuasive speech to the class.

Allie has a new basketball. She has a hard time finding someone to play with her because they believe basketball is a boys game. Allie continues to practice and play, despite their opinions.

Students learn about alliteration, and then practice using alliteration in acrostic poems, tongue twisters, alphabet books, and number books.

This seminar will introduce three of eight types of figurative language (alliteration, onomatopoeia, and idiom).  Through mainly fictional texts( tongue twisters, comics, songs, etc.), you will  identify these types of figurative language, determine their meanings, and  formulate project-based activities to prove your understanding of these common figurative language types.StandardsCC.1.2.5.F  Determine the meaning of words and phrase as they are used in grade-level text, including interpretation of figurative language.

Students define and classify alloys as mixtures, while comparing and contrasting the properties of alloys to those of pure substances. Students learn that engineers investigate the structures and properties of alloys for biomedical and transportation applications. Pre- and post-assessment handouts are provided.

Acting as engineering teams, students take measurements and make calculations to determine the specific strength of various alloys and then report their data to the rest of the class. Using this class data, students write data-based recommendations to NASA regarding the best alloy to use in the construction of the engine and engine turbines for the Space Launch System that will eventually be used to transport astronauts to Mars.

Students use this online tool to create an alphabet chart or pages for an alphabet book.

Mainly an Islamic site for children, this section of Play & Learn provides an introduction to all of the letters in the Arabic alphabet. There are a total of 74 printable worksheets, some of which provide practice for children to write the letters and some intended for children to recognize the letters in their connected and unconnected forms. The worksheets also provide practice with long vowels and tanween and the site provides downloadable audio pronunciations of each letter.

Students are asked to explain what needs to be considered if alternative energy sources are to be used. ***Access to Teacher's Domain content now requires free login to PBS Learning Media.

Amag! is the architecture magazine for children.

It is a game to cut, brake, destroy…

It is for all children from 5 to 10 years.

It is an Open Educational Resource (OER) for schools around the world.

Amag! is a building material, as well as a game, and a research tool. Children learn about architecture, playing with the pages of the magazine.

Amag! consists of articles: A4 for download, print and play. Each article is created by an author or team. All of them are specialist on architecture education for children and youth, or art professionals related to children.

Aerogel, commonly called "frozen smoke," is a super-material with some amazing properties. In this lesson and its associated activity, students learn about this silicon-based solid with a sponge-like structure. Students also learn about density and how aerogel is 99.8% air by volume, making it the lightest solid known to humans! Further, students learn about basic heat transfer and how aerogel is a great thermal insulator, having 39 times more insulation than the best fiberglass insulation. Students also learn about the wide array of aerogel applications.
