Students try to grow plants on Mars-likesoilBy Milwaukee Journal Sentinel, adapted by Newsela staff on 11.12.15Word Count 878UW-Stout student Molly Beaghan of Houghton, Michigan, waters plants in the "Hab," or habitat, which contains ChippewaCounty soil. The soil turned reddish after it was heated to 1,000 degrees Fahrenheit to decompose the organic material.Brett T. Roseman/UW-StoutMILWAUKEE, Wis. — Thanks to two professors from the University of Wisconsin-Stout,some lucky students are getting a truly out-of-this-world experience.The professors, one a geologist and the other an ecologist, re-created the dusty surface ofMars to help their students better learn about life on the planet. They constructed an areato resemble Mars in a dirt lab and a greenhouse on the university campus. Their goal wasto help students explore the plot of “The Martian,” Hollywood’s blockbuster space movieabout what it takes to support life and grow food on Mars.To recreate the surface, the professors gathered about 400 pounds of glacial subsoil fromnearby. They cooked the soil at 1,000 degrees for about two hours to kill off all lifesustaining organic materials.This article is available at 5 reading levels at https://newsela.com.1

Then they challenged their students to figure out what to add so potatoes could grow inthe reddish-orange soil. This particular soil was lacking in the good stuff that soil on Earthnaturally contains, similar to what Mars is really like. One group of the students were in asoil science and conservation class.Tackling Complex ProblemsThis was a hands-on experience by all accounts. Students didn’t learn by memorizingfacts and definitions of soil science. Rather, they tackled a complex problem that requiredthem to apply critical thinking to foundation knowledge in order to find solutions. Then theyplayed the what-if game as they began to understand how all the pieces fit together.“It’s like taking a fun toy apart to see how it works, and then putting it back together,” saidMatt Kuchta, a UW-Stout professor of biology and geologist who teaches the soil scienceand conservation class.“The Martian,” starring Matt Damon as an astronaut stranded on Mars, is a hit in the movietheaters across the country. It’s based on a 2011 science fiction novel by Andy Weir. Andwhile the elaborate technical details are accurate, the parts about the wind on Mars arefiction.While Mars is famous for being inhospitable for any kind of life, the astronaut in the movieis a resourceful botanist who figures out how to grow food in a covered habitat with everybit of bio-matter he can find. He uses various things, from food scraps to his own waste,combined with a little bit of water. His goal is to survive until he can be rescued.Kuchta, the professor, started reading the book the movie is based on last January, andquickly realized the plot was almost entirely based on soil science.“One of the goals for the human race is to explore and view other worlds,” Kuchta said. “Itstruck me as a perfect theme to help students understand concepts of soil science, andnot just rural agriculture. It’s important if we want high yields of corn or soybeans, butunderstanding the soil system also is important to manage a forest or conserve a prairiehabitat.”Simulated Martian Soil . From Chippewa CountyKuchta actually got the idea to simulate the soil on Mars from his father, a high schoolbiology and chemistry teacher with an environmental science background. Kuchta took hisadvice to use glacial subsoil locally from Chippewa County, which he then sterilized withhigh temperatures. The subsoil is soil from below the surface, consisting of sand, gravel,silt and clay dropped by melting glaciers tens of thousands of years agoMandy Little, a professor of biology who is married to Kuchta, also helped with theexperiment.This article is available at 5 reading levels at https://newsela.com.2

Her students added composted garden soil from decayed organic matter, like vegetablesor leaves, to the "Martian" soil in an attempt to grow potatoes. They faced manychallenges, including the fact that many of the potatoes rotted because of diseases in thecomposted soil.The class started with a clean slate and watched how plants extract water from the soil;how microorganisms interact with organic and mineral components of soil; and what kindsof minerals are present and provide important nutrients for plant life.“It’s all about understanding how the system works and being able to make predictionsbased on how the soil system will respond to various changes,” Kuchta said.Everything Is ConnectedEarth’s soil system is interconnected with the biosphere in which living organisms arefound. Gases are exchanged between the soil and the atmosphere, and rain in theatmosphere has an impact. These different elements can break down fragments of rocksand minerals in the soil system, which then connects to geology.Some students suggested adding hair to the soil because that's something that would beavailable to someone isolated on another planet. They also thought about adding foodscraps and bits of clothing.They didn’t use human waste to fertilize the soil, like in the movie. Instead, they used wormdroppings called casings.Making Science AccessibleThe first class assignment was to read the first chapter of the book online. The professorsalso showed their classes the trailer for “The Martian” movie.“I want them to be interested in science and have it be accessible,” Little said.Scientists don't have all the answers when they first tackle a problem. Seeing firsthand howscientists do research, develop theories and make informed decisions about their workwith limited information, helps students understand the role science plays in society, shesaid.This article is available at 5 reading levels at https://newsela.com.3

Lesson 1: What Plants Need . This lesson is the firstlesson in a series that introduces children in Year 1 to the world of plants. Children will understand that plants need warmth, light andwater in order to grow. They will look at the ideal conditions for plants and will grow their own plants from seeds.

Plants - find out why plants need water to grow. Year 3: Plants - identify the functions of different parts of flowering plants and explore the requirements of plants for life.

How do plants grow and change? Plants grow and change in two important ways. Non-flowering plants germinate (produce and fertilise) their own seeds to reproduce another plant. Whilst, plants that flower, reproduce with the help of insects through pollination. This is when an insect such as a bee flies from plant to plant, collecting pollen.
