In this NASA activity, students in grades 1-8 learn about the challenges of space nutrition and designing food packaging by observing, measuring, comparing, and contrasting the ripening of fruits and vegetables when exposed to air and the effect of chemical treatments to inhibit ripening.
The year is 2032 and your middle-school explorers have successfully achieved a manned mission to Mars! After establishing criteria to help look for signs of life, they conduct a scientific experiment in which they evaluate three “Martian” soil samples and determine if any contains life.
In this lesson to teach middle school students how a spacecraft gets from the surface of the Earth to Mars, students first investigate rockets and how they are able to get us into space, then discuss the nature of an orbit as well as how orbits enable us to get from planet to planet.
As a teacher, you’re supposed to have all the answers–but you know that sometimes, you just don’t. What if you always had an engineering expert to provide inspiration and advice? The National Academy of Engineering (NAE) recently announced the launch of LinkEngineering, a new website that connects preK-12 teachers with engineering experts, fellow educators, lesson plans, tips, and tools.
Elementary students investigate major landforms (e.g., mountains, rivers) in groups of two. They build a 3D model of a landscape depicting several of these landforms. Once they have built their model, they act as civil and transportation engineers to build a road through the landscape they have created.
High school students working in teams of four learn how a device made with dye from berries can be used to convert light energy into electrical energy by building their own organic solar cells and measuring performance based on power output.

In this activity for middle school science, high school physics, or engineering, groups of students explore the housing crisis caused by natural disasters by applying appropriate technology and fluid mechanics to design sustainable shelters that can withstand flooding and high winds.
Teams 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.
Math can be a tough sell. Many students think it’s too hard, or that they’re no good at it. It doesn’t have to be this way, says Stanford Graduate School of Education Professor Jo Boaler, who has designed a free program for teachers to change mindsets and inspire their fifth through ninth graders to think more deeply in mathematics.
