Bats are mammals. They feed on their mother’s milk often until they’re 5 weeks old.

Kristen Lear understands why some people find bats frightening. The nocturnal animals are often portrayed as spooky and dangerous. “Say you’re watching a scary movie, and the characters are walking through a creepy house,” she says. “What’s going to fly out and attack them? Bats!”

But this scene isn’t realistic, says Lear. Bats aren’t out to get us—in fact, many need our help. As a scientist at Bat Conservation International, Lear works to protect bats and their habitats. She recently spoke with SuperSTEM about sticking up for bats.

Kristen Lear knows why some people find bats scary. They’re nocturnal animals. They’re often shown as being spooky. “Say you’re watching a scary movie,” she says. “And the characters are walking through a creepy house. What’s going to fly out and attack them? Bats!”

But this scene isn’t very true to life, says Lear. Bats aren’t out to get us. In fact, many need our help. Lear is a scientist at Bat Conservation International. She works to save bats and their habitats. She recently spoke with SuperSTEM about sticking up for bats.

How did you become interested in bats?

I’ve always liked animals that other people fear, like rats, snakes, and spiders. Bats have that image problem too. They’re out at night, so you don’t usually get to see them. But that air of mystery is what draws me in.

In sixth grade, I wanted to do a Girl Scout project to help animals. I decided to build bat houses. Those are artificial shelters where bats can rest during the day. I learned a lot about bats and what they need to survive. In college, I studied zoology, the science of animals. I got to work with bats hands-on. That’s when I was hooked!

What do people misunderstand about bats?

Bats make some people nervous because they’re connected with darkness and nighttime. But they’re wild animals, just like birds or foxes. We can live alongside them.

Because there are bats called “vampire bats,” people sometimes think all bats suck blood. But there are more than 1,400 species of bats in the world, and most of them eat insects! Others eat fruit or nectar from flowers.

There are only three species of vampire bats, and they live in Mexico and Central and South America. They don’t typically feed on people. When they bite other animals, they make a tiny cut and drink the blood with their tongues. Most of their “victims” don’t even notice and go about their business!

Why is helping bats important?

Bats live on every continent except Antarctica. There are bats in deserts, cold places like Alaska, and cities. They play important roles in every ecosystem where they live.

Bats that eat insects help keep pest populations under control. Fruit bats spit or poop out fruit seeds, which helps new plants grow. Nectar-feeding bats get covered in tiny pollen grains when they visit flowers. They carry the pollen from flower to flower, helping the plants reproduce.

Unfortunately, a lot of bats are losing their habitats. For example, people are cutting down forests where bats live. Bats need those natural areas to feed, hunt, and sleep. Without them, they may not survive.

How do you protect bats in your job?

I work with three species of nectar-feeding bats that migrate between the Southwest U.S. and Mexico every year. Along the way, they eat nectar from agaves (uh-GAH-vayz), desert plants similar to cactuses. Like bats, agaves have also lost their habitats because of people changing the environment. My team is working to replant agaves and restore the land to a healthy state.

To do that, we need to collect a lot of data. I want to know exactly where bats stop as they migrate. That helps us decide where to plant new agaves and which existing habitats need protection. Agaves can take more than 10 years to bloom and produce nectar, so it’s important to think ahead!

What can people do to support bats?

If you have a garden or a balcony, you can make a bat garden. If nectar-feeding bats live in your area, you can plant species they eat. If you plant flowers that bloom at night, they’ll attract nocturnal insects for insect-eating bats to eat.

Also, share your bat knowledge with friends and family! Over time, it can help more people come to appreciate bats.

You can make a bat garden. You just need a garden or a balcony. You can grow plants that nectar-feeding bats eat. And you can plant flowers that bloom at night. They’ll attract nocturnal insects as food for insect-eating bats.

Also, share what you’ve learned about bats! It can help others learn to love and value bats too.

Step-by-Step Lesson Plan

1. PREPARE TO READ (15 minutes)
Evaluate whether information about bats is true or a myth.

  • Show students the cover of SuperSTEM, hiding the text “Busting Bat Myths.” Have students turn and talk with a partner about what they know or have heard about bats. Reconvene and ask students to share their bat knowledge with the class. List students’ responses on the board.
  • Reveal the text on the cover. Ask students what they think it means to “bust a myth.” (e.g., correct something false that people assume is true) Tell them they are going to find out what’s true about bats and what’s a myth.
  • Play the video “The Truth About Bats.” Revisit your class list of bat knowledge. Ask students: Did you learn new information that disproves any of these statements? Have students turn and talk before discussing as a class. Draw a line through each disproved myth (but leave them visible for later). Ask: Did you learn any other new information about bats? Add new statements to the list.

2. READ AND SYNTHESIZE (15 minutes)
Read the article and synthesize information about a bat scientist.

  • Preview the article and discuss the STEM vocabulary. Read the article aloud, pausing to highlight the key details that show what Kristen Lear does and what she needs to know for her job as a bat scientist. Ask: Why does Lear think people should help bats and how? Then tell students they’re going to create something that could help bats!

3. RESPOND TO READING (45 minutes)
Design a message to help educate the public about bats.

  • Read the directions and steps in the activity Promote Bat Protection. Encourage students to review the list of bat information from Step 1 along with visuals from the story to help them make their design. If desired, share examples of other bat conservation resources that can inspire their work.
  • Post completed work and allow students to do a gallery walk. Ask them to look for and record at least one piece that has something in common with their design and another that is very different.
