Students design systems that use microbes to break down a water pollutant (in this case, sugar). They explore how temperature affects the rate of pollutant decomposition.

Students will learn about the animals that use the migration corridor that stretches from the Grand Tetons in Northwest Wyoming to the Red Desert in South Central Wyoming. Students will watch portions of the PBS documentary “Migrations” to learn about about the challenges these species face. Students will identify threats to animals that use the migration corridor and develop potential solutions that could reduce the negative impact of human activities.

Students will breed fruit flies through several generations and record their data using mathematical models in order to demonstrate the inheritance of trait variations.

Acting as biomedical engineers, students design, build, test and redesign prototype heart valves using materials such as waterproof tape, plastic tubing, flexible plastic and foam sheets, clay, wire and pipe cleaners. They test them with flowing water, representing blood moving through the heart. As students creatively practice engineering problem solving, they demonstrate their understanding of how one-way heart valves work.

Students further their understanding of the engineering design process (EDP) while being introduced to assistive technology devices and biomedical engineering. They are given a fictional client statement and are tasked to follow the steps of the EDP to design and build small-scale, off-road wheelchair prototypes. As part of the EDP, students identify appropriate materials and demonstrate two methods of representing solutions to their design problem (scale drawings and simple scale models). They test the scale model off-road wheelchairs using spring scales to pull the prototypes across three different simulated off-road surfaces.

This hands-on experiment will provide students with an understanding of the issues that surround environmental cleanup. Students will create their own oil spill, try different methods for cleaning it up, and then discuss the merits of each method in terms of effectiveness (cleanliness) and cost. They will be asked to put themselves in the place of both an environmental engineer and an oil company owner who are responsible for the clean-up.

Using their knowledge of the phases of matter, the scientific method, and polymers, student teams work as if they are chemical engineers to optimize the formula for slime. Hired by the fictional company, Slime Productions, students are challenged to modify the chemical composition of the basic formula for slime to maximize its "bounce factor."

Solar energy in the form of light is available to organisms on Earth in abundance. Natural systems and other organisms have structures that function in ways to manage the interaction with and use of this energy. In this storyline, students will explore how light energy interacts with materials and how light energy can be transformed into energy for heating and cooling. Students design a solar water heater and explore how products like this can reduce carbon emissions to mitigate climate change.

This personalized playlist lets students have voice and choice and move at their own pace as they learn about energy types and sustainable energy. The playlist is aligned to the NGSS Science and Engineering Practice Developing and Using Models. The final project is to develop and use a model of their choice to show and explain their learning.

Warming oceans and melting landlocked ice caused by global climate change may result in rising sea levels. This rise in sea level combined with increased intensity and frequency of storms will produce storm surges that flood subways, highways, homes, and more. In this activity, visitors design and test adaptations to prepare for flooding caused by sea level rise.

Through the two lessons and five activities in this unit, students' knowledge of sensors and motors is integrated with programming logic as they perform complex tasks using LEGO MINDSTORMS(TM) NXT robots and software. First, students are introduced to the discipline of engineering and "design" in general terms. Then in five challenge activities, student teams program LEGO robots to travel a maze, go as fast/slow as possible, push another robot, follow a line, and play soccer with other robots. This fifth unit in the series builds on the previous units and reinforces the theme of the human body as a system with sensors performing useful functions, not unlike robots. Through these design challenges, students become familiar with the steps of the engineering design process and come to understand how science, math and engineering including computer programming are used to tackle design challenges and help people solve real problems. PowerPoint® presentations, quizzes and worksheets are provided throughout the unit.

Students learn how two LEGO MINDSTORMS(TM) NXT intelligent bricks can be programmed so that one can remotely control the other. They learn about the components and functionality in the (provided) controller and receiver programs. When its buttons are pressed, the NXT brick assigned as the remote control device uses the controller program to send Bluetooth® messages. When the NXT taskbot/brick assigned as the receiver receives certain Bluetooth messages, it moves, as specified by the receiver program. Students examine how the programs and devices work in tandem, gaining skills as they play "robot soccer." As the concluding activity in this unit, this activity provides a deeper dimension of understanding programming logic compared to previous activities in this unit and introduces the relatively new and growing concept of wireless communication. A PowerPoint® presentation, pre/post quizzes and a worksheet are provided.

On this episode of STEM in 30, follow the path of the suit Alan Eustace wore in his world record skydive from concept to design and from production to execution.

See what happens when Astronaut Kjell Lindgren puts marshmallows into a vacuum in this lesson of ISS Science.

Use their knowledge of air, through a vacuum activity, to determine what will happen to objects when pressure is increased and decreased.

In this lesson students investigate how the layers of a spacesuit protect an astronaut in space.

Astronaut Randy Bresnik walks us through the different parts that make up a spacesuit. Also learn how to make and test your own spacesuit using a potato.

Students will be able to display their understanding of robotics by sharing their robotic hand.

Students learn about one method used in environmental site assessments. They practice soil sampling by creating soil cores, studying soil profiles and characterizing soil profiles in borehole logs. They use their analysis to make predictions about what is going on in the soil and what it might mean to an engineer developing the area.
