Wonder

Wonder is an amazing feeling! Nature peaks our curiosity and sense of discovery with hands-on learning.

At Locust Grove Nature Center the Lunchers had an opportunity to wonder about amphibians and reptiles.

First they met our naturalist and discussed which animals were amphibians--frogs, toads, and salamanders. They learned that amphibians are vertebrates. They lay their jelly-like eggs in water. The eggs will hatch into tadpoles. The tadploes grow hind legs, then front legs before absorbing their tails as they mature into frogs. That's metamorphosis!




It took some close inspection to see the masses of frog eggs in the pond!

The mother Wood Frog laid her eggs, but she did stay to take care of them.

 The eggs were transparent with tiny black embryos inside. They will emerge as tadpoles in about two weeks IF the weather stays warm.

It was too chilly for salamanders and toads on the trail!

We did hear Spring Peepers and lots of birds.

We found a vernal pond in the meadow.  The pond appears each spring after the snow and rain run down the hills. Vernal ponds are the perfect nursery for frogs and toads. Did you know toad eggs look like a long string of beads in the water while frog eggs look like bunches of grapes?

It was also too cold for the resident snakes who like to sun themselves on the trail so we met Seeker, a corn snake who lives at the Nature Center. 

Seeker's skin felt smooth and dry.  He's a reptile like alligators, crocodiles, and lizards so he had scales!

There was also a black snake who was rescued after an accident with a car. He was bigger than Seeker, but could not catch his own food because his jaw was broken.

Reptiles and amphibians are fascinating, but so are honeybees! Montessori had an opportunity to learn about honeybees on Friday when Peter and his dad visited our classrooms.

Mr. Cavanaugh and Peter brought their new bee hive to Montessori.

It was made out of wood.  It had a door at the bottom and lots of frames inside.

The bees will build their combs on the frames.  Then the queen can begin laying her eggs.

Honeybees guard, clean, and cool the hive.  The workers take care of the young, tend the queen, and look for nectar to make honey. A beekeeper helps the bees care for the hive. He needs protective gear just in case the bees think he is an intruder(mouse, bear, raccoon or skunk).

The brush will gently brush away the bees so the keeper can check to make sure the hive is healthy.

The smoker makes the bees feel sleepy.

The hive has two sections.  Each section hold frames. The Cavanaughs will have 3,000 bees moving into the hive on Monday.  In about two months there will be 10,000 bees in their hive! We learned that honeybees are insects.  They will go from egg to larvae to pupa to adult in the hive. That's metamorphosis! They help pollinate the plants and trees so we will have flowers, fruits and vegetables. Bethesda should have some beautiful gardens this summer! Thank you, Cavanaughs!


Spring is a time of wonder!

Are you wondering how many Montessori children will be herpetologists and beekeepers?!

Hello, Eddie!


The Owls recently spent a morning learning about reptiles and amphibians with a naturalist from the Audubon Society.  They learned about the essential features of both. They learned about habitats and camouflage.

Reptiles and amphibians are vertebrates just like us!
Snakes have lots of ribs.
A turtle's spine is attached to its carapace.
Reptiles have scales. Snakes shed their skin to grow.
How do they shed?  They crawl out the same way you turn a sock inside out!

 Frogs have moist skin.  They live near water.

Frogs lay jelly-like eggs in the water. Snakes lay leathery eggs on land.

Amphibian babies do not look like their parents. It's metamorphosis--tadpole to frog!

Meet a special visitor--Eddie!  Eddie is an Eastern Corn Snake.

Eddie eats mice and is not aggressive. He has teeth, but no venom.

Eddie felt smooth and dry--not slimy!
He was friendly!


We'd like to visit Eddie at the Audubon Society!

The Owls learned that both reptiles and amphibians are vertebrates. Both can be herbivores or carnivores.  Both lay eggs.  They also learned how to be scientists--asking questions, exploring materials, and discovering information. Ask your Owl how amphibians and reptiles are different!
