This task provides a familiar context allowing students to visualize multiplication of a fraction by a whole number. This task could form part of a very rich activity which includes studying soda can labels.

Students learn about providing healthcare in a global setting and the importance of wearing protective equipment when treating patients with infectious diseases like Ebola. They learn about biohazard suits, heat transfer through conduction and convection and the engineering design cycle. Student teams design, create and test (and improve) their own Ebola biohazard suit prototypes that cover one arm and hand, including a ventilation system to cool the inside of the suit.

Students are introduced to static equilibrium by learning how forces and torques are balanced in a well-designed engineering structure. A tower crane is presented as a simplified two-dimensional case. Using Popsicle sticks and hot glue, student teams design, build and test a simple tower crane model according to these principles, ending with a team competition.

In this task students must figure out how much fresh water you must add to get a particular salt concentration in aquarium water.

Summer Slugger is a fun, interactive, online resource that uses the game of baseball to help children maintain and reinforce their math and literacy skills.

Students apply their knowledge of constructing and programming LEGO MINDSTORMS (TM)NXT robots to create sumobots - strong robots capable of pushing other robots out of a ring. To meet the challenge, groups follow the steps of the engineering design process and consider robot structure, weight and gear ratios in their designs to make their robots push as hard as possible to force robot opponents out of the ring. A class competition serves as the final test to determine the best designed robot, illustrating the interrelationships between designing, building and programming. This activity gives students the opportunity to be creative as well as have fun applying and combining what they have learned through the previous activities and lessons in this and prior units in the series. A PowerPoint (tm) presentation, pre/post quizzes and a worksheet are provided.

This problem provides students with an opportunity to discover algebraic structure in a geometric context. More specifically, the student will need to divide up the given polygons into triangles and then use the fact that the sum of the angles in each triangle is 180_.

Parts (d) and (e) of this task constitute a very advanced application of the skill of making use of structure: in (d) students are being asked to use the defining property of even and odd functions to manipulate expressions involving function notation. In (e) they are asked to see the structure in the system of two equations involving functions.

The intent of this problem is to have students think about how function addition works on a fundamental level, so formulas have been omitted on purpose.

This short video and interactive assessment activity is designed to teach third graders an overview of addition (sums to 1,000).

This short video and interactive assessment activity is designed to give fourth graders an overview of addition (sums to 1,000).

This short video and interactive assessment activity is designed to teach second graders an overview of addition (sums to 1,000).

Students build a model of the Sun-Earth-Moon system, exploring how the Moon revolves around the Earth, and the Earth around the Sun. Students play a memory game and learn some characteristics about the three objects.

The course aims is to understand the relation between urban design and planning and the aspects of: - sun, energy and plants - wind, sound and noise - water, traffic and other networks - earth, soil and site preparation - life, ecology and nature preservation - living, human density, economy and environment These themes in sustainable urban engineering are related to legends for design, described in a wide variety of lecture papers (720 pages, 1000 figures, 200 references, 5000 key words, 400 questions), accompanied by interactive Excel computer programmes to get quantitative insight. The assignment is an evaluation of an own earlier and future design work integrating sun, plantation, wind, noise, water, traffic, earth, land preparation, cables and pipes, life, natural differentiation, living, density, environment and proposing new legends for design. Study Goals The student: - is able to link urban interventions to urban development technology and within that interrelate urban designers to relevant technical specialists - is able to integrating sun, plantation, wind, noise, water, traffic, earth, land preparation, cables and pipes, life, natural differentiation, living, density, environment - is able to develop new legends for design from the perspective of sustainable urban engineering

Watch shadows during the course of the day to explore the influence of the Sun’s position in the sky on them, as well as how they change over the seasons. During the next season, repeat the experiment and note the changes from the previous season. Repeat over a period of one year for each season.

Students are challenged to design, build and test small-scale launchers while they learn and follow the steps of the engineering design process. For the challenge, the "slingers" must be able to aim and launch Ping-Pong balls 20 feet into a goal using ordinary building materials such as tape, string, plastic spoons, film canisters, plastic cups, rubber bands and paper clips. Students first learn about defining the problem and why each step of the process is important. Teams develop solutions and determine which is the best based on design requirements. After making drawings, constructing and testing prototypes, they evaluate the results and make recommendations for potential second-generation prototypes.

Use this hands-on activity to demonstrate rotational inertia, rotational speed, angular momentum, and velocity. Students build at least two simple spinners to conduct experiments with different mass distributions and shapes, as they strive to design and build the spinner that spins the longest.

This course focuses on one important engineering application of superconductors - the generation of large-scale and intense magnetic fields. It includes a review of electromagnetic theory; detailed treatment of magnet design and operational issues, including "usable" superconductors, field and stress analyses, magnet instabilities, ac losses and mechanical disturbances, quench and protection, experimental techniques, and cryogenics. The course also examines new high-temperature superconductors for magnets, as well as design and operational issues at high temperatures.
