📖 Vocabulary

Engineer A person who designs and builds things to solve problems
Model A small version of something real, used to study and test ideas
Need Something a living thing must have to survive (food, water, shelter, space)
Shelter A safe place that protects an animal from weather and predators
Design A plan for how to build or make something to solve a problem
Criteria The requirements a design must meet to be considered successful

🌍 Background

Every animal has a habitat that meets its needs. A habitat must provide food, clean water, shelter from predators and weather, and enough space. When scientists want to protect an endangered species, they first study its natural habitat and then try to create or preserve places that meet all those same needs.

Engineers design things to solve problems. When you design a habitat model, you are acting as both a scientist (understanding the animal's needs) and an engineer (building something to meet those needs). This kind of thinking — identifying needs, designing solutions, and testing and improving — is called the Engineering Design Process.

Today you will choose one small animal: an earthworm, a ladybug, or a snail. You will find out what it needs, then build a model habitat from everyday household materials. By the end, you will be able to explain why every part of your habitat is there and what animal need it meets.

🐾 Know Your Animal

Read the animal info card for your chosen animal before you start designing:

🪱 EARTHWORM
🐞 LADYBUG
🐌 SNAIL

🔬 Activity: Design and Build Your Habitat

Step 1 — Choose: Pick your animal: earthworm, ladybug, or snail. Write its name on your Student Worksheet.
Step 2 — Research: Read the animal info card above. Fill in the needs chart on your Student Worksheet: what does your animal need for food, water, shelter, and space?
Step 3 — Plan: On the design sketch page in your Student Worksheet, draw a top-down view of your habitat and label what you plan to include and where.
Step 4 — Build: Gather your materials and build the habitat inside the shoebox. Add each element one at a time. As you add each piece, ask: "Which need does this meet: food, water, shelter, or space?"
Step 5 — Label: Make small flag labels (paper folded over a stick or pencil) for every part of your habitat. Each label should say what the element is AND which animal need it meets.
Step 6 — Present: Explain your habitat to a family member. Tell them: what animal lives there, what each part provides, and how you know your animal could survive there.

💬 Discussion Questions

🗣️ Question 1: What would happen to your animal if one part of the habitat was removed? Pick one part and explain.

Suggested answer: Every part of the habitat serves a need. If you removed the water source, the snail or earthworm would dry out and die. If you removed the leaves, the earthworm would have nothing to eat. If you removed the shelter (the leaf roof), the ladybug would be exposed to predators and weather. Every element is there for a reason — this shows how fragile real habitats are when even one thing changes.

🗣️ Question 2: How is your model habitat the same as a real habitat? How is it different?

Suggested answer: The same: it provides food, water, shelter, and space. Different: it is much smaller, it does not have weather or seasons, it lacks predators and the community of other animals the real animal would interact with. A model is always a simplified version used to test ideas. Scientists use models all the time and always note their limitations — a model helps us understand without being as complex as reality.

🗣️ Question 3: If you could add one more thing to improve your habitat, what would it be and why?

Suggested answer: This is open-ended by design! Students might add more food, a better shelter, other species to make it more realistic, or more space. The key is that students justify their choice by linking it to a specific animal need. This is engineering iteration — engineers are always looking for ways to improve a design after testing it.

After building, check off each item:

My habitat has a food source for my animal
My habitat has a water source
My habitat has shelter (protection from weather or predators)
My habitat has enough space for my animal to move
Every part of my habitat is labeled with what need it meets
