DES MOINES, Iowa (AP) — Federal prosecutors say a northwest Iowa ethanol plant owner has pleaded guilty to failing to pay employment taxes and dumping ethanol into a stream. Randy Less, of Hopkinton, was charged in January with failing to collect and pay to the government federal income, Social Security and Medicare taxes withheld from the wages of employees of Permeate Refining.

DES MOINES, Iowa (AP) — The Iowa Court of Appeals says two men convicted of second-degree murder for their involvement in the mob beating death of a Des Moines man in a downtown parking lot in 2013 will get new trials.

ALTOONA, Iowa (AP) — An IRS report says that a central Iowa casino owes up to $60 million in back taxes and penalties. The Des Moines Register reports that Prairie Meadows Racetrack and Casino’s board of directors released a 93-page IRS report Wednesday that threatens to revoke its tax exempt-status and a letter protesting federal agency’s actions. Casino officials learned about the IRS’ plans to take away its tax-exempt status May 12, following a year-and-a-half investigation.

CEDAR RAPIDS, Iowa (AP) — A Cedar Rapids highway currently under construction appears on track to open ahead of schedule. Cedar Rapids television station KCRG reports that the first half of the Highway 100 extension could open by Thanksgiving. It had been scheduled to open sometime next year, with the entire project to open in the fall of 2018.

School’s out for the summer, but hundreds of Iowa science teachers are going back to class over the next few days. Iowa Department of Education spokesperson Staci Hupp says they have teamed up with Grand View University to work with teachers on the new science standards adopted last fall. “We call this an immersion institute — and what that means is we want educators to really have an opportunity to experience what it would be like to be a student in the classroom using the new science standards,” Hupp says.

They’ve brought in national and state science education leaders to work with the teachers on ways to teach using the new standards. She cites an example of one of the lessons. “They’ll have the teachers looking at field corn that has been siting out versus corn that has been sitting in water soaking for a week and then the scientific phenomenon associated with that. So, this really gets to idea of helping students experience and explains science, ” Hupp says. “So in that field corn example — this is saying as a student I am going to observe this as a scientist would — ask questions, and then use my knowledge and skills to explain why the field corn won’t sprout after it has been sitting in water for a week.”

This is the second year of the four-year implementation of the new science standards, which take a new approach to teaching science. “Our previous science standards were based on learning from the late 1990s, and so much about science and our understanding about how students learn about science has changed over that time,” according to Hupp. “The new standards identify those science and engineering practices and content that students should master in order to be prepared for success in college and the workforce.” The institute is designed to give teachers ideas to use in their classroom.

“What we want people to walk away with is to look at our science standards and say ‘what are some local contexts that I can use to spark interest in my students so that they want learn about it,’ and then use critical thinking skills to explain it and potentially solve the scientific problem,” Hupp says. She says the Department of Education is trying to help districts as they decide how best to implement the new standards.

“The standards articulate expectations for what students should know and be able to do at particular grade levels, but its really up to the local schools to make those curriculum decisions. Including decisions about what is taught and how it is taught,” Hupp says. The institute takes place over three days, with elementary teachers taking part today (Wednesday), middle school teachers tomorrow and high school teachers Friday. It is being held at West Des Moines Valley High School.
