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 learn that fats found in the foods we eat are not all the same; they discover that physical properties of materials are related to their chemical structures. Provided with several samples of commonly used fats with different chemical properties (olive oil, vegetable oil, shortening, animal fat and butter), student groups build and use simple LEGO MINDSTORMS(TM) NXT robots with temperature and light sensors to determine the melting points of the fat samples. Because of their different chemical structures, these fats exhibit different physical properties, such as melting point and color. This activity uses the fact that fats are opaque when solid and translucent when liquid to determine the melting point of each sample upon being heated. Students heat the samples, and use the robot to determine when samples are melted. They analyze plots of their collected data to compare melting points of the oil samples to look for trends. Discrepancies are correlated to differences in the chemical structure and composition of the fats.

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.

This free and rich content platform provides access to thousands of fun kids activities like children’s crafts, worksheets, coloring pages, printable mazes, dot to dot, hidden pictures and more. Various activities are available for children of all ages.

This week, we're headed back to India to learn about the all night dance shows that culminate in killing a Demon (metaphorically): Kathakali! This form arose in the Kerala region of India, and tells traditional Indian stories, but with really remarkable makeup, hand positions, and dance moves.

Students learn about linear programming (also called linear optimization) to solve engineering design problems. As they work through a word problem as a class, they learn about the ideas of constraints, feasibility and optimization related to graphing linear equalities. Then they apply this information to solve two practice engineering design problems related to optimizing materials and cost by graphing inequalities, determining coordinates and equations from their graphs, and solving their equations. It is suggested that students conduct the associated activity, Optimizing Pencils in a Tray, before this lesson, although either order is acceptable.

Students will explore the variety of milks available and the source of those milks.

This lesson is about Saturn's largest moon, Titan. Learners will listen to a narrative "told" by the Huygens probe, entitled Memoirs of a Spacecraft. Visualization and drawing are used as motivators to enhance comprehension and to get students thinking about Titan and what we might find there. Next, students will read a factual article, entitled All About Titan and the Huygens Probe, and write a summary. This is lesson 8 of 12 in the Mission to Saturn Educators Guide, Reading Writing Rings, for grades 3-4.

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 will analyze and describe a painting depicting a family. They will discuss similarities and differences between the setting of the painting and where they live. Then students will create a sculpture of their family doing an activity together and also create a diorama of a room in their home.

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

Students will be introduced to the term alliteration and create a headline poem consisting of 25 words that contain at least three examples of alliteration.

"De nos jours, les débuts des apprentissages en lecture et en écriture des enfants se font bien avant leur entrée à l’école. Les enfants baignent dans des environnements où les mots, les sons, les textes et les images sont présents partout, accessibles sur différents supports (livres, écrans, affiches, etc.). Or, ces apprentissages ne peuvent se faire sans un enseignement plus explicite de la lecture et de l’écriture. Plus les enfants développent tôt une certaine habileté à jouer avec les mots et les sons ainsi qu’à apprendre les lettres de l’alphabet, plus leurs chances de persévérer et de réussir à l’école sont grandes."

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.
