Simple machines are devices with few or no moving parts that make work easier, and which people have used to provide mechanical advantage for thousands of years. Students learn about the wedge, wheel and axle, lever, inclined plane, screw and pulley in the context of the construction of a pyramid, gaining insights into tools that have been used since ancient times and are still important today. Through numerous hands-on activities, students imagine themselves as ancient engineers building a pyramid. Student teams evaluate and select a construction site, design a pyramid, perform materials calculations, test a variety of cutting wedges on different materials, design a small-scale cart/lever transport system to convey building materials, experiment with the angle of inclination and pull force on an inclined plane, see how a pulley can change the direction of force, and learn the differences between fixed, movable and combined pulleys. While learning the steps of the engineering design process, students practice teamwork, creativity and problem solving.

In Unit 2 of the Explore the Salish Sea curriculum, students will review the water cycle, learn the parts of a watershed, and the effects of erosion and pollution, then learn ways of purifying these waters before they enter our streams and estuaries to safeguard these ecosystems for marine life and us.
Each unit in this series contains a detailed unit plan, a slideshow, student journal, and assessments. All elements are adaptable and can be tailored to your local community.

The moon is more explored than the ocean, and that includes the Salish Sea. Where it is inconvenient or even impossible for people to go, we can engineer technology to go there for us, like the Mars Rovers, space probes, automatic unmanned vehicles, drones, and in this unit, remotely operated vehicles (ROV’s). Ocean Tech revisits the engineering process, but this time it requires physical, mechanical, and electrical engineers working together as a team to achieve a student-driven mission.

Chapter 5, Life in the Deep: The Subtidal World, is our first look into the amazing life forms that live their whole lives underwater. Is there access to the subtidal world near your school? If you can get to one (even if it is a pond or a pool), your students’ engineering efforts will find their reward. What mystery or problem will your students explore with their own ROV? Dive in!

Students further their understanding of the salmon life cycle and the human structures and actions that aid in the migration of fish around hydroelectric dams by playing an animated PowerPoint game involving a fish that must climb a fish ladder to get over a dam. They first brainstorm their own ideas, and then learn about existing ways engineers have made dams "friendlier" to migrating fish, before being quizzed as part of the game.

In this Unit, students embark on a mission to create a campaign which promotes seat belt use for a teenage audience. In the context of this project, students explore NGSS PE’s 3-PS2-2, 3-PS2-1, 3-5-ETS1-1, 3-PS2-3, and 3-PS2-4 while investigating the effects of balanced and unbalanced forces acting on an object. Through a series of collect evidence to write a claim based on evidence for why seatbelts are important.

Students model and design the sound environment for a room. They analyze the sound performance of different materials that represent wallpaper, thick curtains, and sound-absorbing panels. Then, referring to the results of their analysis, they design another room based on certain specifications, and test their designs.

Students will learn about the water cycle, watersheds, and specifically, the watershed that feeds Springfield, Oregon. After analyzing drought maps, reading news reports, and seeing images and videos, students will realize that drought is a real life concern. Students, as concerned citizens, will create a water collection device, at first on a small scale, and then a true to life water collection system to help re- purpose rainwater in our garden area.

Ligers exist! But, why does a liger look like a mystical creature? Students will design a simulated genetically engineered animal for a biotechnology engineering firm, which creates newanimals.

Students investigate motors and electromagnets as they construct their own simple electric motors using batteries, magnets, paper clips and wire.

In this activity students practice measuring techniques by measuring different objects and distances around the classroom. They practice using different scales of measurement in metric units and estimation.

Students explore the use of wind power in the design, construction and testing of "sail cars," which, in this case, are little wheeled carts with masts and sails that are powered by the moving air generated from a box fan. The scientific method is reviewed and reinforced with the use of controls and variables, and the engineering design process is explored. The focus of the activity is on renewable energy, as well as the design, testing and redesign of small cars made from household materials. The activity (and an extension worksheet) includes the use of kinematic equations using distance, time traveled and speed to enforce exponents and decimals.

Students engage in the second design challenge of the unit, which is an extension of the maze challenge they solved in the first lesson/activity of this unit. Students extend the ideas learned in the maze challenge with a focus more on the robot design. Gears are a very important part of any machine, particularly when it has a power source such as engine or motor. Specifically, students learn how to design the gear train from the LEGO MINDSTORMS(TM) NXT servomotor to the wheel to make the LEGO taskbot go faster or slower. A PowerPoint® presentation, pre/post quizzes and a worksheet are provided.

This Educators Guide provides everything you need to make this virtual field trip a huge success with your students! You will find lists of materials and resources, step-by-step instructions for three complete lessons, journal prompts as well as research topics, supplementary card work, and standards mapping.

Student teams follow the steps of the engineering design process to meet the challenge of getting their entire class from one location on the playground to the sidewalk without touching the ground between. The class develops a well thought-out plan while following the steps of the engineering design process. Then, they test their solution by going outside and trying it out. Through the post-activity assessment, they compare their problem-solving experience to real life engineering challenges, such as creating new forms of transportation or new product invention.

Students brainstorm and discuss the different types of materials used to build houses in various climates. They build small models of houses and test them in different climates.

A lesson plan for 4th grade science. Kids create a version of the marble roll project to simulate a manufacturing process.

Do you have coffee filters, masking tape, and some bendy straws handy? Grab those and a few more supplies from your kitchen and you're ready to start thinking like an engineer.

Students explore the inhalation/exhalation process that occurs in the lungs during respiration. Using everyday materials, each student team creates a model pair of lungs.
