Students review the what they have learned throughout the five lessons in this unit. This includes a review of many types of engineers, reminding students of the various everyday products, structures and processes they design and create in our world.

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.

Introducing engineering concepts with Hour of Engineering website is an engaging way to get students thinking about a STEM future. Hour of Engineering is designed to inform and inspire students in upper elementary through high school about engineering. Helping your students build an innovation mindset with the adaptive tools to solve problems starts here!

By participating in the Hour of Engineering students will: Define STEM vocabulary; Display engineering literacy; Explore the engineering design process; Experiment with practical engineering skills; Solve real-world engineering challenges; Link concepts between science, technology, engineering, and math; Build engineering habits of mind like creativity, systems thinking, and collaboration.

There are three parts to the Hour of Engineering website: landing page with inspirational content, learning modules, and engineering design challenges. (1) The landing page features clickable items to inspire students about the connection between engineering, art, science, math and even music! Students can freely explore the videos and models to learn about each object before moving on to deeper learning. (2) Learning modules allow students to explore a specific engineering topic. Students can explore learning modules on their own or you can pair them with connected engineering challenges to guide a sequence of learning on a topic. (3) Engineering challenges are a gamified way for students to explore various topics, activities and objects within fields of engineering. Students participating in engineering challenges earn stars based on their interaction with learning elements. There are knowledge checks and interactive models for students to explore during a challenge.

In this video segment from PEEP and the Big Wide World, children experiment with cardboard and build a house for their stuffed animals.

This article reprints and links to informational text about the art and science of igloos. Versions are available for students in grades K-1, 2-3 and 4-5. Related science and literacy activities are included.

Students are introduced to a challenge question. Towards answering the question, they generate ideas for what they need to know about medicines and how they move through our bodies, watch a few short videos to gain multiple perspectives, and then learn lecture material to obtain a basic understanding of how antibiotics kill bacteria in the human body. They learn why different forms of medicine (pill, liquid or shot) get into the blood stream at different speeds.

Students teams determine the size of the caverns necessary to house the population of the state of Alabraska from the impending asteroid impact. They measure their classroom to determine area and volume, determine how many people the space could sleep, and scale this number up to accommodate all Alabraskans. They work through problems on a worksheet and perform math conversions between feet/meters and miles/kilometers.

Students learn about geotechnical engineers and their use of physical properties, such as soil density, to determine the ability of various soils to offer support to foundations. In an associated activity, students determine the bulk densities of soil samples, and assess their suitability to support foundations.

Students determine the mass and volume of soil samples and calculate the density of the soils. They use this information to determine the suitability of the soil to support a building foundation.

This article discusses the physical and behavioral adaptations that allow birds to survive in cold climates such as the polar regions.

Students learn that it is incorrect to believe that heavier objects fall faster than lighter objects. By close observation of falling objects, they see that it is the amount of air resistance, not the weight of an object, which determines how quickly an object falls.

This video segment adapted from FETCH! shows contestants experimenting with different materials to see which is the best insulator and thus best able to keep the lemonade at their stand cool for customers.

The physics of smartphones is a complicated and amazing mixture of engineering, physics, electronics and computer science. Video (6:03)

While learning about volcanoes, magma and lava flows, students learn about the properties of liquid movement, coming to understand viscosity and other factors that increase and decrease liquid flow. They also learn about lava composition and its risk to human settlements.

Students practice their multiplication skills using robots with wheels built from LEGO® MINDSTORMS® NXT kits. They brainstorm distance travelled by the robots without physically measuring distance and then apply their math skills to correctly calculate the distance and compare their guesses with physical measurements. Through this activity, students estimate parameters other than by physically measuring them, practice multiplication, develop measuring skills, and use their creativity to come up with successful solutions.

Students measure the permeability of different types of soils, compare results and realize the importance of size, voids and density in permeability response.

This illustrated essay from A Science Odyssey Web site explains the science behind radio waves, including the role of electrons and electromagnetic fields.

In this fast-paced NASA Brain BitesŒ_íěÖ video, an astronaut demonstrates the impact of microgravity on the use of tools in space.

Students learn about the underlying engineering principals in the inner workings of a simple household object -- the faucet. Students use the basic concepts of simple machines, force and fluid flow to describe the path of water through a simple faucet. Lastly, they translate this knowledge into thinking about how different designs of faucets also use these same concepts.

Students investigate different forms of hybrid engines as well as briefly conclude a look at the different forms of potential energy, which concludes the Research and Revise step of the legacy cycle. Students are introduced to basic circuit schematics and apply their understanding of the difference between series and parallel circuits to current research on hybrid cars.
