The Amazing World of Mealworms (3rd grade reading level/4th grade standards
by Unknown
Have you ever seen a mealworm? You might think they are worms because of their name, but here is a surprise: mealworms aren't worms at all! They are actually the larvae (baby stage) of a creepy-crawly insect called the Darkling Beetle.
Growing mealworms is a fun science project. It lets you watch an insect change its shape and grow right before your eyes. This amazing change is called metamorphosis.
The Four Stages of Life
Just like butterflies, mealworms go through four big changes in their life.
Egg: It all starts with a tiny white bean-shaped egg. They are so small, they are hard to see!
Larva (Mealworm): A tiny mealworm hatches from the egg. This is the stage you usually buy at the pet store. They love to eat and grow. As they get bigger, they shed their skin (molt) many times.
Pupa: When the mealworm is done growing, it turns into a white, alien-looking sleeping bag called a pupa. It doesn't eat or move much during this time. Inside, its body is changing completely.
Adult (Darkling Beetle): Finally, a beetle comes out of the pupa! At first, it is white and soft, but soon it turns black and hard. The beetle lays new eggs, and the cycle starts all over again.
How to Build a Mealworm Farm
You can make a happy home for mealworms with things you probably have at home.
What You Need:
- A plastic container (like a shoe box or food tub)
- Oatmeal or wheat bran (this is their bedding and their food!)
- A slice of potato, apple, or carrot
- Mealworms (you can get these at a pet store)
Steps:
Add Bedding: Pour about 2 inches of oatmeal into your container.
Add Moisture: Place the slice of potato or carrot on top of the oats. This gives the mealworms water to drink.
Add Mealworms: Gently put your mealworms into the container.
Air Holes: Poke small holes in the lid so they can breathe, or leave the lid off if the sides are slippery (mealworms can't climb slippery walls!).
Taking Care of Your Mealworms
Mealworms are easy pets, but they still need care.
Change the Food: Every few days, check the potato or carrot. If it looks dry or moldy, throw it away and put in a fresh piece.
Keep it Clean: After a while, you might see a dusty sand at the bottom. This is called frass (mealworm poop!). You can sift it out using a strainer to keep their home clean.
Temperature: Keep them in a warm room. If it gets too cold, they will stop growing. If you put them in the refrigerator, they will go to sleep (hibernate)!
Why Do We Grow Them?
People grow mealworms for many reasons. Some people use them to feed pets like lizards, birds, or hedgehogs. Others grow them to learn about science and insect life cycles. Believe it or not, in some parts of the world, people even cook and eat mealworms as a healthy snack!
Questions
Based on the passage, why does the author suggest using a plastic container with slippery sides for the mealworm farm?
So the mealworms cannot crawl out of the container easily
So the oatmeal bedding can stay cold and fresh for longer
So the lid of the container can close more tightly each time
So the potato or carrot will not dry out as quickly inside
Standard: RI.4.1
What is the main idea of the passage?
Mealworms are helpful pets that are very easy to take care of at home.
Mealworms go through four life stages, and you can build a farm to watch these changes.
Darkling beetles lay eggs that are hard to see because they are very tiny and white.
People like to use mealworms to feed pets like lizards, birds, and hedgehogs.
Standard: RI.4.2
A class wants to watch their mealworms change through all four life stages. Based on the passage, why should they NOT keep their mealworm farm in the refrigerator?
Because the refrigerator will make the potato or carrot moldy faster.
Because the refrigerator will make the beetles lay too many eggs at once.
Because the refrigerator will cause the oatmeal bedding to dry out quickly.
Because the refrigerator will make the mealworms go to sleep instead of growing.
