You still need a better reason to plant a tree?

Police aren’t cheap and neither are lawyers, judges, and all the other layers that make up the justice system. But trees and some grass, in comparison, are a real bargain, and they prove to be effective in lighting crimes.

Many cities used to launch programs to plant vegetation along roadways to help absorb rainwater. After tracking 14 types of crime in nearby areas, Michelle Kondo, a social scientist found that a variety of crimes including property crimes such as theft and burglary, and violent crimes such as armed fights and mayhem in those areas decreased to 27 percent, a stunning 18 percent fall. Kondo believed the appearance of city trucks and vans in the landscaped areas— for planting and maintenance— was enough to scare away potential criminals.

Kondo’s study also worked on the link between grassland care and decrease of the crime in downtown areas. It’s tempting to use income as the connection. After all, if you have the crime and money to water your lawn, you probably live in a neighborhood that sees less crime. But actually, people are less likely to hang in those areas where the streets are maintained or cleaned. “You will see less kids hanging on the corners.’’ Kondo said. He argued that caution of the local people implied by the organized greenery helped to frighten away ill-intentioned guys, by announcing to would-be criminals that there are “eyes on the street’’ that care for their neighborhood and would be more likely to report a crime.

We already know greenery is beautiful to look at and can help improve mood and health while reducing pollution. Now we can add crime-fighting to the list of vegetation’s many benefits. Therefore, are you ready to plant a tree?

Drawing High Schoolers to Science

A group of educators and plant scientists at Michigan State University (MSU) are connecting to reshape science classes. And this particular partnership isn’t just helping students get a better understanding of biology; it’s turning them into young scientists, even if only during class.

It doesn’t take long to see that the curriculum born from this collaboration makes for a much different experience than the traditional high school biology classes. For starters, it has a comic book for a workbook. Secondly, students are getting their hands dirty growing plants. MSU researchers are also studying the plant. The high schoolers are asking some of the same questions professional plant scientists are trying to answer.

“We’re getting them engaged with science in science practices, not just having them learn about science,” says Hildah Makori, a researcher at MSU. “They learn to look at things differently. That’s a life-time impact.”

The main characters of the comic book are a pair of young field scientists. They invite the high school students to help with plant research inspired by a real project at MSU. By growing their own plants, the students learn about genetics, evolution and how these interact with the environment.

The team has seen how this practice could keep students in the driver’s seat of their learning. To help the characters out, students set up different experiments to test their ideas.

The program is working. “This comic personally gave me a click that sparked my curiosity,” reads one student’s survey response. “The comic book put a lot of creative atmosphere into the story instead of just looking at words, instead of just listening to the teacher talk,” says another.

Teachers also had positive reviews. In a survey, one remarked how helpful it was to have the comic to refer to. The students could see the comic’s characters doing something in the lab and realize, “I’m able to do this right here at my table and I can do the same thing,” the teacher says.
