The Chicago Field Museum is one of the largest and most respected natural history museums in the world. Let’s take a fascinating journey behind the scenes to discover some of its incredible treasures!
Imagine opening a drawer and finding a creature with eyes that seem to stare back at you. It’s both exciting and a bit nerve-wracking! Some of these specimens have features that are truly bizarre, like teeth that don’t seem to fit together properly. These unusual characteristics make us wonder why nature creates such diversity.
One of the fascinating aspects of these creatures is their spines, which can be poisonous. The venom is produced in a gland and travels along the spine, possibly to ward off other males. However, there’s still much to learn about these animals, which is why scientists study these specimens to test different ideas about their function, form, and evolution.
The platypus is one of the most intriguing animals. Many people think its duck bill is hard, but in reality, it’s soft and rubbery. This bill is packed with nerves that help the platypus sense tiny creatures in the mud. Holding a platypus specimen, you can see its eyes and imagine it being quite content in its natural habitat.
Some animal skins are too large to fit in drawers, so the museum uses giant refrigerators to store them. These cold rooms are filled with amazing specimens, including grizzlies, polar bears, and even pandas. Sometimes, people donate animal rugs they no longer need, which the museum modifies for display.
The museum’s collection includes a variety of animals, such as sloths, tanned hides, and an African lion from 1935. It’s fascinating to think about how recently some of these specimens were added to the collection. You can even see where some animals were shot, highlighting their beauty and history.
In addition to physical specimens, the museum also collects DNA samples from amphibians and reptiles. Each container can hold about a hundred tissue vials, and with thousands of vials in storage, organization is key. Handling these samples requires care, as they can be dangerous without proper protection.
Whenever a new specimen arrives, the museum tries to collect a tissue sample. This practice is becoming standard in natural history museums because preserving DNA is crucial for future research. The museum acts like a lending library of genetic material, providing samples to researchers working on legitimate projects.
By preserving these DNA samples, the museum holds onto the potential for future scientific discoveries. As research advances, these samples could reveal new insights into the natural world, making the museum an invaluable resource for scientists worldwide.
Exploring the Chicago Field Museum is a journey into the wonders of nature, showcasing the incredible diversity of life and the ongoing quest to understand it better.
Imagine you are a scientist at the Chicago Field Museum. Design your own unusual creature with unique features. Draw your creature and write a short description explaining its special characteristics and how they might help it survive in the wild. Share your creation with the class and discuss the diversity of life.
Learn more about the platypus’s unique sensory abilities. Research how its bill works and create a simple experiment to demonstrate how sensory nerves help animals detect their environment. Present your findings and experiment results to the class.
Take a virtual tour of the Chicago Field Museum’s collections. Choose one specimen that interests you and research its history and significance. Prepare a short presentation to share with the class, highlighting what makes your chosen specimen unique.
Role-play as museum staff responsible for preserving DNA samples. Discuss the importance of DNA preservation and the process involved. Create a step-by-step guide on how to handle and store DNA samples safely, and present it to your peers.
Engage in a debate about the potential future discoveries that could be made using the museum’s DNA samples. Form teams to argue either for or against the importance of preserving DNA for future research. Use examples from the museum’s collection to support your arguments.

The Chicago Field Museum is one of the largest and most respected natural history museums in the world. Join me as we go behind the scenes!
– Pull that drawer open. I’m a bit nervous. Oh my gosh! Why does nature create things like this? It has eyes! Why does it look like this? Is this the mandible? What are these teeth? They don’t seem to fit together properly! This is so unusual!
– Look at this specimen. It looks like an insect. I can’t comprehend why its teeth look like this. It’s the most bizarre thing I’ve ever seen!
– And you know about the spines, right? Yes, they have poisonous spines.
– Venom is produced in the gland and travels along the spine. The current thinking is that it helps to keep other males at bay. But there’s still so much we don’t know about these animals. This is why we have the specimens here, so we can test different hypotheses about their function, form, and evolution.
– I just don’t understand why everyone isn’t studying platypuses. They’re the most fascinating creatures! People often think the duck bill is quite hard, but in life, it’s actually quite soft and rubbery. There are many nerves running between those teeth and the beak that help them sense invertebrates in the mud.
– I’m holding a platypus right now. It has eyes and seems happy!
– Some skins are too large to keep in the drawers, so we have these giant skin refrigerators.
– Whoa, pulling out the key. It’s very serious in here! It’s like our cold room but huge! These specimens are amazing. You have grizzlies and polar bears!
– People sometimes donate rugs they no longer need, so we have modified polar bear rugs.
– Is that a panda? Yes, it is! You have pandas! And dogs like German Shepherds and St. Bernards.
– You also have sloths and other unique specimens, tanned hides, and an African lion from 1935. It’s interesting to think about how recently these specimens were contributed.
– You can see where they were shot. They are such gorgeous specimens.
– So, what is this DNA from? These are tissue samples of amphibians and reptiles.
– How many can fit in one of these containers? Usually, there are a hundred tissue vials in a box.
– So, with 13 boxes in every rack, that’s about 1,300, and with 54 racks, it totals around 70,000 vials.
– Yes, that’s a lot of vials! That’s why we have to be very organized.
– It looks like it could be dangerous. Yes, if you’re not wearing gloves, it can be.
– So, do you take tissue samples from every new specimen that comes in? We like to have tissue samples of everything if possible.
– We just received a collection from Honduras today, and everything came with a tissue sample.
– So, it’s becoming standard practice for natural history museums to keep parts of DNA? Yes, it’s important to collect a tissue sample before preserving the specimen, as formalin can damage the DNA.
– And with the DNA sample, what will you do with it? We hold onto it and see what science reveals.
– We’re essentially a lending library of genetic material. If someone is doing a research project and it looks legitimate, we’ll send them a sample.
– That’s really fascinating!

Specimens – Samples of organisms used for scientific study or display. – The biology class examined specimens of different plant leaves to learn about their structures.
Diversity – The variety of different species and forms of life within an ecosystem. – The coral reef is known for its incredible biodiversity, hosting thousands of marine species.
Evolution – The process by which different kinds of living organisms develop and diversify from earlier forms over generations. – Charles Darwin’s theory of evolution explains how species adapt to their environments over time.
Habitat – The natural environment where a plant or animal lives and grows. – The polar bear’s habitat is the icy regions of the Arctic, where it hunts for seals.
