Welcome to Ms. Lenahan’s Class!

Hello out there! I am sure some of you now know that I am your teacher since the letters were sent home this week. If you are here to learn more about our class, you came to the right place!

I will be posting information here for both students and parents to prepare for our new school year. I will post more in the coming days, so don’t worry.

Why not poke around for a while? Read some of the things we did in our class this past year. Check out the photos as there are many of them! And please leave comments if you feel comfortable. They are always welcome!

Your new teacher,

At the Refuge…again!



Alexandra, Noelia and I sure worked up a sweat today! After helping Al and Peter with the baby purple martins, we chopped down a lot of old milkweed. The Refuge has a very nice garden in front of the visitors’ center. There was tons and tons of milkweed there this year, but it has gone to seed and needed to be cut back. If we want monarchs to lay eggs here this summer and fall, they need fresh milkweed leaves. The milkweed we cut back was also covered with aphids. Aphids are a very strange and interesting insect that lives off the milkweed plant.alexandraalexandra2alexandra4alexandra5

Summer School Monarchs!

ss class 09Hi everyone,

I hope you all are having an enjoyable summer vacation. My vacation officially started on Thursday afternoon at 4:01pm. Yippee! Now I don’t have to go back to work for almost 5 weeks.

Summer School was a nice four weeks. I had a group of 16 second and third grade students.  We started off with a few caterpillars and lots and lots of eggs! Students got to see an amazing site–a brand new monarch caterpillar eating its way out of the shell! We observed this phenomena under the microscope, so students could see the little guy munching away. (I hope to have a digital microscope in September so that we can take enlarged photos of this happening!)

The caterpillars soon got fat on their exclusive diet of milkweed. Most of the milkweed came from our newly planted LAS garden. John, my amazing partner in crime, was key in getting my garden into the ground. We worked on many of his days off to till and dig the soil, prepare the beds and plant the milkweed.  Thank you so much, honey!

Dara, Julia, Robert and the whole gang were fascinated by the caterpillars. Arianna and Andrea wrote stories about them. Quentin drew diagrams of their life cycles. We watched as the cats grew and grew. As they entered their next stage of life, Vanessa seemed mesmerized as the caterpillars hung upside down in a letter J.

a thing of beauty

On the last day of summer school, the final stage of metamorphosis happened. I placed a ‘tower’ of chrysalides at each group in the classroom. Vanessa quietly and politely came to me and told me it was happening. We all rushed to the tower to observe a new butterfly as it pushed its way out of the now almost transparent chrysalis. Everyone held their breath as the legs came out, then the rest of the butterfly. Yippee! The smiles were on everyone’s faces as each butterfly made its way into the world.

We ended our summer school with new, magical beginnings.

Rather poetic, don’t you think?
