5th grade students take a trip to the Farm School

Farm School students have been studying the water quality of the pond and local rivers in the Watershed Occupation Project.  This week, they taught Mountain Laurel Montessori 5th year students how to test for dissolved oxygen, nitrates, and pH.

Spring Lambs Arrive!

We have 3 new lambs at the Farm School!

We were all able to observe this ram lamb being born

This lambing season was challenging, but provided many opportunities for biology lessons and real life decision making. Many thanks to Brandon, our Farm Manager, for his attention to the sheep; he is going to be happy to get a good night's sleep now!

Students learn to extract DNA

Thanks to microbiologist and Farm School parent Dr. Lilburn for leading a DNA extraction lab this week!

The 9th year Biology students have been studying genetics and heredity. The lab was such a great opportunity that all of the students in grades 7-9 participated.  We extracted the DNA from dried peas (a nod to Gregor Mendel).

How's the Water?

Mountain Laurel Montessori Farm School 9th year Biology students investigate the water quality of the school's pond.  

The students used a kick-net to collect samples of aquatic macroinvertebrates.  We found damselfly and dragonfly nymphs and even a mayfly nymph!  Mayfly nymphs will only live in very high quality water with lots of dissolved oxygen.

This aquatic study is part of a species inventory the students are undertaking of the entire property to determine the level of biological diversity of the farm.
