The Molecular Biology classes at Southeast Polk have had the opportunity to go to the Environmental Learning Center and apply what they have been learning in the classroom to things in nature. The ELC located off campus is filled with ponds, prairie and lots of wildlife.
Molecular Biology is a class for mostly sophomores and juniors. Junior Holly Dannen went to the ELC earlier this week.
“The ELC is a great place to apply what we learn in class to nature. We get to do hands on stuff and lots of different experiments,” Dannen said.
Students are learning about different pH levels by doing some chemical testing and also what types of organisms are in the ponds by doing biological testing.
“It is very interesting to see how the pH varies from spot to spot in the pond also finding out how many small living things call the pond their home is crazy.” said Dannen.
The ELC ponds are filled with everything from fish to frogs and even water scorpions. Students collect samples of the water and then are able to study what living things they caught. They also take samples of the water to test dissolved oxygen levels, temperature and pH.

“The ELC is an awesome place and we are lucky to be able to go there and study and just spend time in nature rather than in the classroom,” said Dannen.
