When you add water to effervescent (fizzy) tablets or baking powder, bubbles are formed: a gas is produced. You can use this gas to inflate a balloon without blowing it up yourself. What kind of gas is it? Let us collect this gas and analyse it through experiments.
Objective
SWBAT plan and carry out an investigation using science and engineering practices.
Big Idea
Welcome to the water park! Students will create a “lazy river” boat from aluminum foil that will hold the most passengers.
This lesson introduces students to the important concept of density. The focus is on the more easily understood densities of solids, but students can also explore the densities of liquids and gases. Students devise methods to determine the densities of solid objects, including the method of water displacement to determine volumes of irregularly-shaped objects. By comparing densities of various solids to the density of water, and by considering the behavior of different solids when placed in water, students conclude that ordinarily, objects with densities greater than water will sink, while those with densities less than water will float. Density is an important material property for engineers to understand.
Students conduct several simple lab activities to learn about the five fundamental load types that can act on structures: tension, compression, shear, bending and torsion. In this activity, students play the role of molecules in a beam that is subject to various loading schemes.
This is a set of resources based around forensics (using CSI as a platform). It contains elements to do with fingerprinting; separation techniques; codes; DNA extraction and chromatography.. It could be used in conjunction with a 'mock crime'; or as 'CSI training'.
The lesson will first explore the concept of current in electrical circuits. Current will be defined as the flow of electrons. Photovoltaic (PV) cell properties will then be introduced. Generally constructed of silicon, photovoltaic cells contain a large number of electrons BUT they can be thought of as "frozen" in their natural state. A source of energy is required to "free" these electrons if we wish to create current. Light from the sun provides this energy. This will lead to the principle of "Conservation of Energy." Finally, with a basic understanding of the circuits through Ohm's law, students will see how the energy from the sun can be used to power everyday items, including vehicles. This lesson utilizes the engineering design activity of building a solar car to help students learn these concepts.
After the Great Depression struck, Ford especially wanted to support ailing farmers. For two years, Ford and his team researched ways to use farmers’ crops in his Ford Motor Company. They discovered that the soybean was the perfect answer. Soon, Ford’s cars contained many soybean plastic parts, and Ford incorporated soybeans into every part of his life. He ate soybeans, he wore clothes made of soybean fabric, and he wanted to drive soybeans, too.

Meet savvy scientist and inventor Hedy Lamarr, also known for her career as a glamorous international movie star. Dubbed "The Most Beautiful Woman in the World," Hedy actually preferred spending time creating inventions in her workshop to strutting down the red carpet. Hedy co-invented the technology known as frequency hopping, which turned out to be one of the most important scientific breakthroughs of the twentieth century! Today's cell phone, computers, and other electronic devices would be more vulnerable to hacking without the groundbreaking system discovered by a world-famous actress and gifted inventor. The resource includes a lesson plan/book card, a design challenge, and copy of a design thinking journal that provide guidance on using the book to inspire students' curiosity for design thinking. Maker Challenge: Create small groups. Pass out one of the challenges listed in the lesson plan/book card to each group for them to come up with an invention that will solve the problem at hand.
Frances Gabe detested housework, so she invented a contraption to free herself from this tedious task forever: a self-cleaning house! Gabe's wacky, wonderful home included almost 70 new patented inventions, from a soap-spraying sprinkler in the ceiling to a kitchen cabinet that washed, dried, and stored dishes all in one place. Though Gabe's invention didn't catch on, her determination and clever thinking remind us that we don't have to accept the world as it is; we can improve it using our minds and our own two hands. The resource includes a lesson plan/book card, a design challenge, and copy of a design thinking journal that provide guidance on using the book to inspire students' curiosity for design thinking. Maker Challenge: Frances Gabe created over 70 inventions because she hated cleaning. What is one thing you hate doing for chores? Develop an invention to have it clean itself.

This wiki page documents the Sun Curve Design Challenge, inspired by the "Sun Curve" aquaponic garden sculpture to challenge teachers and students to produce new OER materials and incorporate green design thinking into the classroom.
This lesson will allow students to build their own balloon car racer as an introduction to engineering and coding. Each pair or team of students will be able to engineer their balloon car, measure the performance of their cars using yard sticks, and set up a basic algorithm to construct and run their machine.PURPOSEThe goals for this lesson are to: (1) integrate engineering and coding to young students; (2) have students independenty identify the steps (an algorithm) to build and improve their racers; (4) be able to spot "bugs" in their algorithm; (3) integrate measurement and addition operations to determine which car went furthest overall; and (4) teach perserverance by showing students that it is normal to find bugs in algorithms/coding.
Meg set out to climb up and investigate the rain forest tree canopies — and to be the first scientist to do so. But she encountered challenge after challenge. Male teachers would not let her into their classrooms, the high canopy was difficult to get to, and worst of all, people were logging and clearing the forests. Meg never gave up or gave in. She studied, invented, and persevered, not only creating a future for herself as a scientist, but making sure that the rainforests had a future as well. The resource includes a lesson plan/book card, a design challenge, and copy of a design thinking journal that provide guidance on using the book to inspire students' curiosity for design thinking. Maker Challenge: Your community has many different areas to explore - it might be a park, a grocery store, a forest, or an alley. For some people, it might be difficult to explore these areas because they may have differing abilities. Select one area in your community, and come up with a plan to build a way for it to be more accessible to everyone.

Richard grew up in Kenya as a Maasai boy, herding his family’s cattle, which represented their wealth and livelihood. Richard’s challenge was to protect their cattle from the lions who prowled the night just outside the barrier of acacia branches that surrounded the farm’s boma, or stockade. Though not well-educated, 12-year-old Richard loved tinkering with electronics. Using salvaged components, spending $10, he surrounded the boma with blinking lights, and the system works; it keeps lions away. His invention, Lion Lights, is now used in Africa, Asia, and South America to protect farm animals from predators. The resource includes a lesson plan/book card, a design challenge, and copy of a design thinking journal that provide guidance on using the book to inspire students' curiosity for design thinking. Maker Challenge: Your challenge is to use broken or old technology and other available resources to create a prototype that can be used to protect your home. This could involve tinkering, hacking, or redesigning the components of the technology to meet your needs.
