Skulls, Horseshoes, Parrots and Robots: Fall Teacher Tuesdays offer awesome classroom ideas

It’s officially fall, and I’d like to say the weather is cooling down and the leaves are turning bright and beautiful colors, but we live in Houston. So… no.

Instead, I can tell you that we’ve been hard at work this summer developing fun, fast and hands-on activities for this year’s ExxonMobil Teacher Tuesdays. For adults only, Teacher Tuesdays offer fun and interactive professional development opportunities for ideas to kick your lessons up a notch. We’re pretty excited about the line-up this fall, and we’re dying to give you a sneak peak of what to expect.


Our first ExxonMobil Teacher Tuesday has us focusing on one of our favorite topics: Day of the Dead! With all-new crafts, this workshop is sure to be a crowd-pleaser. Check out the photo above for a hint at the items we’ll be making in class. For those of you who have been to a Day of the Dead workshop before, you’ll be pleased to know that the sparkle box is back!


In October, you can join us for an in depth look at the rock cycle with James Washington, Lead Concierge here at HMNS. James, who leads tours for the museum, has his very own collection of specimens he’s willing to share with the world. Anyone who has participated in what I refer to as “The James Washington Experience” leaves with a much better understanding of how all sciences are connected.


You also have the opportunity to visit the new Hamman Hall of Coastal Ecology on Oct. 27 to discover the critters in and around the ocean. You’ll even get the chance to get up close and personal with a horseshoe crab. (Fun fact: horseshoe crabs keep you healthy in ways you probably don’t even know about but will learn in this mind-blowing workshop.)


For November, pop down to the rainforest as you learn about the Amazon in the Out of the Amazon workshop. As part of the workshop, you will be treated to a rainforest wildlife presentation as well as a tour of the new exhibit Out of the Amazon. Dover and Frankie, our resident green-cheeked conures, might even make an appearance and will within minutes have entire room full of adults trained to do tricks.teacher7Join us in December for a viewing of Robots 3D in the Wortham Giant Screen Theatre. HMNS’s own Kathleen Havens wrote the curriculum for this National Geographic feature, so you know it’ll be hands-on, fun and engaging for students while covering STEM objectives and careers. If you’d like to discover some reasonable engineering challenges you can do at school for your elementary and middle school students that don’t require a $3000 grant, this workshop is for you!


And that just takes us through December! The spring semester is just as exciting, covering everything from blood splatter to brain-based learning. Check out our complete schedule, and we’ll see you at HMNS!

Top 5 Most Frequently Asked Questions in the Cockrell Butterfly Center

The Cockrell Butterfly Center (CBC) strives to bring the natural world to within the public’s reach. Visitors enjoy tropical plants and exotic animals exhibited throughout the indoor rainforest, insect zoo, and practical entomology hall, and as they wander through the CBC, they’re sure to ask tons of questions! To keep you informed, we’ve compiled a list of the top five most frequently asked questions about the CBC and answered them below. Take a look!

Q. Is that real?

A: It depends on what you are asking about.

Usually this question is asked about the chrysalids hanging in the emergence chamber. In that case, the answer is yes! All the chrysalids you see are real! We receive between 800 and 1,000 chrysalids per week. The chrysalids are carefully glued up so the butterflies can emerge in a natural position. If you look carefully, you may see the chrysalids wiggling. You can also observe the freshly emerged butterflies drying their wings. Twice a day, we collect the butterflies with fully dry wings and release them into the CBC rainforest. On Wednesdays until Labor Day weekend, you can watch how we do it during our Wing It! presentation.

These chrysalids are real! Soon butterflies will emerge from each one.

When this question is about the plants in the Rainforest Conservatory, the answer is also yes, but with one exception. All the plants are real except for the huge central tree. This tree contains the rainforest’s air circulation system. All others are living plants that are meticulously cared for by our staff horticulturalist, Soni Holladay. Each plant is labeled, so keep a lookout for a coffee tree, chocolate tree, pride of Trinadad, pineapple plants, miracle berry bush, and a variety of beautiful orchids. 

Before and after! All the plants in the CBC are real with the exception of the large central tree.

Q. How many butterflies are there in here?

A. We keep a collection of more than 1,500 live butterflies in the CBC rainforest at all times. It may seem like more or less, depending on how active the butterflies are. The butterflies are most likely to be actively flying and feeding when there is bright sunlight and warm weather. During these times, the whole rainforest feels like it’s fluttering around you. Early in the morning, or in cooler, overcast weather, many of the butterflies will be quietly roosting underneath leaves. During these times, a sharp eye will allow you to spot the sleeping butterflies all around  you. Take this time to enjoy the variety of colors and patterns that are more easily discernible on butterfly wings that aren’t flying. Owl butterflies, however, are active at dusk. You can watch hundreds of them swirling in our rainforest during our limited-availability event An Evening With Owls, coming in September.


Shhhhhhhhhh! They’re sleeping! Look for roosting butterflies hanging from leaves next time you visit the CBC.

Q. Where do the butterflies come from?

A. We receive the butterflies in their pupal form (chrysalis) through the mail. Each week, we import up to 1,000 live chrysalids from butterfly farms in Central and South America, Southeast Asia, and Africa. We also raise a small portion of the butterflies in the greenhouses on the top level of the parking garage. We receive up to 150 different species of butterflies throughout the year. Use the butterfly identification guides as you enter the rainforest to help you identify some of our most common species!


Our butterflies are shipped from farms all over the world!

Q. What do the butterflies eat?

A. The CBC rainforest is always full of a variety of flowering plants. Most butterflies feed on nectar. Watch the butterflies visiting the blooms and you will notice them extending their proboscis into the center of the flower. They use this mouth part like a straw to draw up the nectar. Supplementary food is provided for the nectar-feeders in feeding stations filled with artificial nectar. Artificial nectar is made from a mixture of water, sugar and amino acids. It is soaked into sponges that the butterflies can visit to get an extra snack. But not all butterflies feed on nectar. Some prefer the juices from rotten fruit or tree sap. For the fruit-feeders we provide banana brew (fermenting bananas, sugar and beer mixture) as well as slices of over-ripe fruit. Butterflies are also known to feed on some less savory substances such and dead animals and feces.

Fun fact: butterflies also get essential nutrients by feeding on feces and carrion!

Q. How long do the butterflies live?

A. It depends. Most butterflies are not long-lived. The average life span for the butterflies in the CBC rainforest is about two weeks. Some, like the Atlas moth, only live a few days. Atlas moths don’t even have mouth parts as adults, so they don’t feed at all! They live off of the fat stores they accumulated as a caterpillar. Several of the long-wing species of butterflies may live up to a couple of months. Perhaps the most well-known species of butterfly, the Monarch, is known for  its amazing migration from Canada to Mexico. The migratory generation of Monarchs can live between 6 and 9 months!

We hope you enjoyed our quick Q&A session! Drop by the CBC any time to satisfy your curiosity further. We’re always around to answer questions.

Tree frogs! Serpents! Monkey-eating birds! Peel back the layers of the rainforest with our new Wildlife on Wheels

Our latest wild and wonderful Wildlife on Wheels (WOW) program focuses on the animals of the rainforest — from tree frogs and slithering snakes to millipedes and rainbow boas.

For example: Did you know that more than half of the world’s plants, animals and insects reside in the rainforest? Its vitality is crucial to the world’s oxygen supply, and its rich plant life is the source of lots of modern medicines.

photo 6Using live animals and specimens, HMNS educators also teach students about the rainforest’s unique quirks. For example: Did you know that 50 percent of rainforest rainfall never even hits the ground?

Glimpse: Spirits & Headhunters [12 Days of HMNS]

Today is the Seventh Day of HMNS! In the spirit of the classic holiday carol, we’re taking 12 days to feature 12 different videos that preview or go behind-the-scenes of a holiday museum activity, here on the blog (or, you can get a sneak peek at all the videos on – we won’t tell).

Many of the exhibits we host here – like Genghis Khan or the Terra Cotta Warriors – present objects from long-dead cultures, and the wonder comes from the experience of coming face-to-face with artifacts that were created so long ago. And when you walk through our current Spirits & Headhunters exhibition, and contemplate the absolute beauty of the vibrant, intricate feather art and objects on display, it’s easy to forget that the cultures that created these works are very much alive – though also fast disappearing.

Learn more from Adam Mekler, associate curator for Amazonia, who believes, “When a culture disappears, I think an aspect of all humanity disappears.”

Click play to explore the exhibit and discover these vanishing worlds.
