GRAND JUNCTION, Colo. (KKCO) _ At least one set of parents are not happy with Olathe Elementary and claim they're not alone.
They say their daughter's fifth grade class took part in what the school is calling a scientific observation of a dead calf.
Olathe Elementary officials say they simply wanted to get the students excited about learning biology by going beyond the textbook.
However, some parents say they went too far.
It was supposed to be an interactive part of the fifth graders biology curriculum; getting a live look at a calf's heart, liver and kidney.
The animal's body was donated and brought to the school on a truck bed with the organs already dissected and on display.
While teachers gave students the option of opting out of the observation, parents say they were given no warning and what the children were exposed to was inappropriate.
"I think that you really need to speak with parents and say if this is appropriate for your child; send something home, send an email out," says one parent.
"We sure don't want to cause a pain and discomfort for any of our kids, but on the other end of that we don't want to limit learning."
Principal Brummit says the school is standing by its lesson plan.
However, in the future they plan to send home notices to parents to make sure everyone is in the know.
