NASA TechRise Student Challenge

NASA high altitude science balloonNASA’s TechRise Student Challenge invites U.S. students in grades 6 to 12 to submit ideas for experiments to be launched on high-altitude research balloons. Some 60 winning teams will receive $1,500 to build their experiments plus an assigned berth for their payloads on a NASA balloon flight.

Lesson: Dirty Water Project

dropletCivil, chemical, and environmental engineers work together to develop new water treatment systems or to improve existing ones. In this activity, teams of students in grades 3-5 investigate different methods for removing pollutants from water, then design and build their own water filters from plastic bottles.

Measuring Water Quality to Assess Human Impact

HackingSTEM water quality samplingMiddle school students explore how fertilizers and other solids affect water quality by building and using sensors to measure the electrical conductivity of water samples. They then create data tables and investigate possible sources of pollutants using digital visualization tools.

Brazil’s Olympic Designs

imaginary stadium with light beamsAs host of the 2016 Summer Olympics, Brazil has had to tap engineering expertise for everything from stadium construction to pollution control to security systems in order to receive an estimated 15,000 athletes and half a million foreign visitors. Despite the country’s economic woes, zika virus concerns, and construction delays, the games will go on… though probably not without some hitches.

Groundwater Pollution Detectives

Water pumpTeams of students in grades 5 to 7 locate a contaminant spill in a hypothetical site by measuring the pH of soil samples. They then predict the direction of groundwater flow using mathematical modeling and use the engineering design process to come up with alternative treatments for the contaminated water.

What a Dump!

landfillIn this activity, teams of students in grades 5 to 7 learn about environmental, civil, and sanitation engineering by designing and building model landfills that hold the most garbage, minimize costs, and prevent trash and contaminated “rainwater” from polluting the nearby “city.” Teams test their landfills, and graph and compare designs for capacity, cost, and performance.
