Hey there! Have you ever seen a cactus? These are special plants that don’t need much water, making them easy to grow as decorations in homes. You might have seen them in pots or even growing in the wild if you live in parts of North or South America. Cacti come in all sorts of shapes and sizes, and many have sharp spines.
Let’s talk about someone amazing named Elia Bravo. She was born in Mexico City in 1901. As a child, Elia loved spending time outside with her family, exploring plants and looking at the stars. She was so fascinated by plants that she decided to study them instead of becoming a doctor, which was her family’s dream for her.
Elia wanted everyone to know about the wonderful plants she grew up with in Mexico. But how could she share this knowledge? There was no internet or social media back then! So, she decided to write a book about Mexican cacti, describing what they looked like, where they grew, and what made them special.
Elia had a big job ahead of her. There were hundreds of different cacti in Mexico, and she was sure there were more that scientists hadn’t discovered yet. She read a lot of research and traveled all over Mexico, hiking through deserts, mountains, and jungles to find cacti. She studied many types, like barrel cacti, prickly pear cacti, and tall saguaro cacti.
Elia wanted people to feel like they were on a cactus adventure with her. She took photos, made sketches, and collected samples of the cacti she found. After years of hard work, she published a book called “Las Cactáceas de México” (The Cacti of Mexico). It was a huge book with over 700 pages and 324 photographs, describing most of Mexico’s cacti.
Elia didn’t stop there. She spent her life studying cacti and teaching others about them. She wrote more books and even started the Cactus Society of Mexico. Thanks to her work, we now know about nearly 2,000 kinds of cacti in the world!
Elia Bravo’s work taught us so much about cacti, and she inspired many others to keep learning. Maybe you’ll be the next person to study cacti or explore something else you’re curious about. Remember, just like Elia, you can share what you learn with others!
That’s all for today! Keep asking questions and exploring the world around you. There are so many mysteries to discover. Stay curious, and see you next time!
Plant Your Own Cactus: With the help of an adult, plant a small cactus in a pot. Observe how it grows over time. Does it need a lot of water? How does it look different from other plants you know? Keep a journal and draw pictures of your cactus as it grows. This will help you understand how cacti survive in dry places.
Cactus Exploration Walk: Go on a walk in your neighborhood or a local park with an adult. Look for different types of plants and see if you can find any cacti. How many different kinds can you spot? Take photos or draw pictures of the plants you find. Think about why some plants might grow better in certain places than others.
Imagine and Create: Pretend you are a cactus explorer like Elia Bravo. Draw a map of a desert and imagine where you might find different types of cacti. What would your cactus adventure look like? Write a short story about your journey and the discoveries you make along the way. Share your story with your family or friends!

Hey, it’s Jay! Ever seen one of these before? This is a plant called a cactus. Maybe you’ve seen one of these growing in a pot before. Cacti don’t need a lot of water, so many people find them easy to grow as decorations for their homes. If you live in certain parts of North or South America, you might have also seen cacti growing in the wild. Cacti come in lots of unique shapes and sizes, and many of them have spiky spines.
Someone named Abby has a question about cacti. Let’s call Abby now.
Hi, Jay! Hi, Abby! I have a question for you: How many cacti are there? That’s a great question! I want to introduce you to someone who knows a lot about this. Her name is Elia Bravo.
Elia Bravo was born in what is now Mexico City in 1901. As a kid, she and her family spent lots of time outside. At night, they stargazed, and during the day, they took walks among the cacti and other plants near their home. Elia fell in love with plants. She did well in school, and her family dreamed that she would grow up to become a doctor. However, she realized she had a different dream, so halfway through studying medicine in college, she switched to studying plants instead.
After she graduated, Elia took on a big new goal: she wanted people everywhere to learn about the plants she’d grown up with in Mexico. I’m curious—if you wanted everyone to learn about plants that grow near where you live, what would you do? How could you share that information? Now would be a good time to pause the video and discuss.
Okay, ready? Elia lived in a time before many of the tools we use to share information today existed. There was no social media, no internet, and far fewer films than there are today. So, she decided to write a book about Mexican cacti. Her book was going to be a guide to the many different kinds of cacti in Mexico: what they looked like, where they grew, and what made them special.
This wouldn’t be easy; there were hundreds of different types of cacti in Mexico, and she was sure there were more that scientists hadn’t even studied yet. She got to work, carefully reading the research of other scientists who had studied cacti before her. Then, she set out into the wild to do her own research. She traveled all around Mexico looking for cacti, hiking through deserts, mountains, and jungles. It was hard work, but the cacti she observed were amazing.
She studied barrel cacti, colorful prickly pear cacti, and tall saguaro cacti. But Elia didn’t just want to learn about these cacti for herself; she wanted to share what she learned. She wanted people reading her book to feel like they were taking a cactus field trip across Mexico, standing next to her as she inspected each cactus. So, she carefully recorded her observations of each kind of cactus she encountered. She took photos, made sketches, and collected plant samples. She described each sample in detail and compared it to other cacti she had seen.
Finally, after years of research, she published “Las Cactáceas de México” (The Cacti of Mexico). She achieved her goal! Her book was more than 700 pages, had 324 photographs, and described most of Mexico’s many kinds of cacti. Nobody had ever put that much information about cacti together in one place. People used her book to learn about cacti for years to come.
But Elia did not stop there. She dedicated the rest of her life to the study of cacti. After publishing her book, Elia became a beloved teacher, helping many others learn to study cacti. She published more research and wrote more books. She started the Cactus Society of Mexico. She knew that the more people learned about cacti, the more they would care about these unique plants and the places in nature where they grow.
Her work was so important that some scientists now call Elia Bravo the “Queen of Cacti.” Because of her work and the work of scientists she taught and inspired, we now have identified nearly 2,000 kinds of cacti in the world.
In summary, much of what we know about cacti is thanks to the work of Elia Bravo. She explored across Mexico and carefully recorded observations of hundreds of types of cacti. She encouraged others to continue her work, and we’ve now recorded nearly 2,000 different kinds of cacti, with still more to discover. Even at the end of her life, Elia knew there was still much more to learn, discover, and share about these plants.
Maybe you’ll be the next person to carry on her work studying cacti, or perhaps you’ll carry on her work in a different way by learning more about the things you’re curious about and sharing what you learn with others, just like she did.
That’s all for this week’s question. Thanks for asking, Abby! We’ll be back with a new episode in a couple of weeks. In the meantime, here are some older questions from the question jar that you can vote on for next week: How do batteries work? Why do we sweat when we play sports? Or how does hand sanitizer kill germs? Submit your vote when the video is over. We want to hear from all of you watching. There are mysteries all around us—stay curious, and see you next week!
