Schools skeptical about adding climate change to curriculum

With Connecticut mulling whether to add climate change to the curriculum, some schools are pushing back.
Many schools already teach about the topic, but a proposal would make it a requirement.
Critics say that would cost too much money to create lesson plans and train teachers.
Jamie Klein, a science teacher at Turn of River Middle School in Stamford, says it's important to teach students about the issue to counter ubiquitous misinformation.
"They will talk about it, discuss it, and they'll come back with all these different ideas for me," Klein says.
Klein's students learn about climate change by replicating the greenhouse effect with mason jars covered in plastic wrap. She says the exercise helps teach kids about a controversial topic based on science -- not emotions.
Even though, she admits, "they're very concerned about the polar bears."
"I'm hoping they can form their own opinion on climate change," she says. "I'm not going to give them my opinion or the adults in their lives. They are learning the science behind it."
