Unit 3 – Reptile Egg STEM

Imagine that you volunteered to rescue reptiles (turtles, snakes, and lizards) that are in the unlucky position of living in the path of new construction. Typically in these cases, animals move. They search for new homes and food sources nearby. However, eggs cannot crawl, slither, or swim to another location. And construction

projects will not wait for eggs to hatch.

You have talked with the construction workers and with a nearby reptile conservation center. The workers are willing to notify you when they come across reptile eggs, The center is able to incubate the eggs until the babies hatch and then return them to the wild. Your role is to design a reptile egg incubation device that keeps an egg warm and safe as it is transported from the worksite to the reptile conservation center.

Reptile eggs are leathery and soft. While they are not prone to crack easily, they need to remain in the same orientation they were originally laid – whatever is facing up, must stay facing up. They cannot be flipped, turned, or jostles. Very

importantly, the eggs must be kept warm, but not too warm, to properly develop and hatch.

You have a job to do before the first batch of eggs is found – build a temporary portable reptile egg incubator device that will keep one egg warm and properly positioned while you take it to the reptile conservation center. Let’s give these young lizards, turtles, and snakes their best chance!

Step 1: Define the Problem Criteria and Constraints

What is the problem or need? Who is it for? (client)

Who has the problem or need? What budget do you have?

Why is it important to solve the problem?

How long do you have to make it?

Write the problem as a statement. What materials can you use?

What scientific principals need to be applied?

Step 2: Develop Solutions

Think back to the scenario about transporting reptile eggs from a construction site to a reptile conservation center. Read the text message from one of the construction workers in the illustration to the left.

Directions: Use the Reptile Egg Identification chart (from the scenario description) to answer the following questions.

1. Do these eggs belong to a snake, turtle, or lizard?

2. What characteristics helped you identify these eggs?

3. As you design your temporary portable reptile egg incubator, you will need to consider the ideal temperature the reptile egg incubator, you will need to consider the ideal temperature the reptile eggs need. What temperature range should you aim for when you mix calcium chloride, baking soda, and water?

Use the space below to design your individual solution:

Use the space below to design your group’s final solution:

Step 3: Plan/Choose the best solutionNow that your group has chosen the best solution, it is time to plan the engineering.

1. What is your plan for your solution?

- What materials will you use to engineer your egg incubator?

- How much will it cost you to make your egg incubator?

- How long will it take you to make your egg incubator?

Step 4: Build and Test How will you know if your egg incubator has been successful?

What tests will you run on your egg incubator before transporting a live egg?

Step 5: Optimize

How can you make your design better?

Reptile Egg STEM Poster

Now that you have selected your final solution, it is time to begin working on your poster!REQUIREMENTS:
