Nevada - Science: Middle School Engineering Design

Crumple Zones

Design a car to protect a test dummy in a collision. Adjust the length and stiffness of the crumple zone and the rigidity of the safety cell to determine how the car will deform during the crash. Add seat belts and/or airbags to prevent the dummy from hitting the steering wheel. Three different body types (sedan, SUV, and subcompact) are available and a wide range of crash speeds can be used. 5 Minute Preview

Earthquake-Proof Homes

Design a house to withstand an earthquake and protect the people living inside. Select a location in San Francisco, then choose the design and materials for a foundation, frame, walls, and roof. Decide which extras to add to your home design. Test each house in an earthquake and assess the damages. Try to arrive at a house design that results in the least damage. 5 Minute Preview

Feel the Heat

Have you ever used a glove warmer to keep your hands warm? How about an instant cold pack to treat an injury? In the Feel the Heat Gizmo, create your own hot and cold packs using various salts dissolved in water and different bag materials. Learn about exothermic and endothermic processes and how energy is absorbed or released when bonds are broken and new bonds form. 5 Minute Preview

Flood and Storm-Proof Homes

Build a home to survive a flood or a hurricane and protect the people inside. Choose materials and a design for the foundation, frame, walls, and roof of the house. Add "extras" such as sand bags, storm shutters, and roof clips. Test your house in a flood or storm and see how well your design worked. 5 Minute Preview

GMOs and the Environment

In this follow-up to the Genetic Engineering Gizmo, explore how farmers can maximize yield while limiting ecosystem damage using genetically modified corn. Choose the corn type to plant and the amount of herbicide and insecticide to use, then measure corn yields and monitor wildlife populations and diversity. Observe the long-term effects of pollutants on a nearby stream ecosystem. 5 Minute Preview

Genetic Engineering

Use genetic engineering techniques to create corn plants resistant to insect pests or tolerant of herbicides. Identify useful genes from bacteria, insert the desired gene into a corn plant, and then compare the modified plant to a control plant in a lab setting. 5 Minute Preview

Pendulum Clock

Find the effect of length, mass, and angle on the period of a pendulum. The pendulum is attached to a clock that can be adjusted to tell time accurately. The clock can be located on Earth or Jupiter to determine the effect of gravity. 5 Minute Preview

Trebuchet

Design your own trebuchet to fling a projectile at a castle wall. All of the dimensions of the trebuchet can be adjusted, as well as the masses of the counterweight and payload. Select a target on the Launch tab, or just see how far your projectile will go. 5 Minute Preview

Beat the Heat: Tackling Urban Heat Islands Using the Science of Energy - Middle School

Lake City's latest heat wave has more people in the hospital than ever before. Juan, a local student admitted to the hospital, lives in one of the hottest neighborhoods in the city. Students are hired as the city's Chief Heat Officer to investigate and solve the problem. As the Chief Heat Officer, students look at land uses, surface air temperatures, and building materials across Lake City. Students will develop a system model to test several design solutions and give the mayor a proposal to beat the heat. Video Preview

Smelling in the Rain: Designing Solutions to Improve Air Quality - Middle School

A respiratory physiologist is concerned about the number of asthma attacks in children within her community. On certain days, the number is higher than the respiratory physiologist might expect. She thinks something in the environment is causing more rescue inhaler use on those days. As an air quality engineer, students will work collaboratively with a respiratory physiologist to learn how some air pollutants are released directly from sources while others are formed through chemical reactions. Students will develop a system model to test design solutions to recommend a plan to help decrease air pollution in a community with a record number of asthma cases in children. Video Preview

Sound Off, Please!: Designing Solutions to Reduce Noise Pollution - Middle School

As an acoustic engineer, students will work with an urban planner to learn how noise pollution impacts a community. Students will develop a system model to test design solutions. Wave properties of sound and how sound interacts with different surfaces will be explored and used as evidence to reduce noise pollution. Video Preview

Water Contamination - Middle School

There has been an outbreak of legionnaires’ disease in a small town. This disease is caused by legionella bacteria that proliferate in contaminated water supplies. Students take on the role of a civil engineer to investigate how the water treatment plant has failed to get rid of all the contaminants in the water and design a new method. Video Preview

Digestive System

Digestion is a complex process, involving a wide variety of organs and chemicals that work together to break down food, absorb nutrients, and eliminate wastes. But have you ever wondered what would happen if some of those organs were eliminated, or if the sequence was changed? Can the digestive system be improved? Find out by designing your own digestive system with the Digestive System Gizmo. 5 Minute Preview

Muscles and Bones

See how muscles, bones, and connective tissue work together to allow movement. Observe how muscle contraction arises from the interactions of thin and thick filaments in muscle cells. Using what you have learned, construct an arm that can lift a weight or throw a ball. Connective tissue, muscle composition, bone length, and tendon insertion point can all be manipulated to create an arm to lift the heaviest weight or throw a ball the fastest. 5 Minute Preview

Programmable Rover

In this introduction to coding, program a rover to explore the surface of Mars. Start by using tiles to create simple programs involving moving forward or backward, turns, jumps, loops, and picking up rock samples. Then use text instructions to optimize your code. Use your skills to program the rover to complete six challenging missions on Mars. 5 Minute Preview
