The State Scientist Expo: A Scientific Tour of the USA

Materials Needed:

• A large map of the USA
• Computer or tablet with internet access for research
• A science journal or notebook and a pen/pencil
• General craft and experiment supplies (cardboard, construction paper, tape, glue, scissors, markers, empty plastic bottles, baking soda, vinegar, etc.)
• For the final project: A tri-fold presentation board, poster board, or access to a presentation software like Google Slides or PowerPoint
• (Specific materials will depend on the experiment Jeaneth chooses. We will determine those during the lesson.)

Lesson Goal

Today, Jeaneth, you won't just learn about a state; you will become a lead scientist for a state of your choice! Your mission is to explore a unique scientific phenomenon related to that state, design a hands-on experiment or model to explain it, and then share your findings at our very own "State Scientist Expo."

Learning Objectives

By the end of this project, you will be able to:

• Identify a unique scientific characteristic (geological, ecological, meteorological, etc.) of a specific U.S. state.
• Develop a testable question based on that characteristic.
• Design and conduct a simple experiment or build a model to answer your question.
• Record observations and draw a conclusion.
• Communicate your findings clearly in a creative presentation.

Part 1: The Investigation - Choosing Your Field of Study (Approx. 45 Minutes)

1. Brainstorming Session: Let's look at the U.S. map. What states are you most curious about? Let's list 3-5 states that seem interesting to you in your science journal.
2. Scientific Scouting: Now, let's do some initial research. For each state on your list, we'll look for its "science story." Think about these questions:
   • What is the land like? (Mountains, deserts, swamps, coastline?)
   • What is the weather like? (Tornadoes, hurricanes, blizzards, lots of sun?)
   • What grows there or lives there? (Giant redwood trees, alligators, unique crops?)
   • What major industries are there that relate to science? (Mining, technology, agriculture?)
3. Select Your State & Formulate a Question: Choose the one state and topic that fascinates you the most. Now, let's turn that topic into a "testable question." A testable question is one we can try to answer with a hands-on project.
   
   Examples to help you think:
   • Topic: Florida has hurricanes. → Testable Question: How does the circular motion of wind and water form a hurricane's eye?
   • Topic: Arizona is a desert with lots of sun. → Testable Question: How can solar energy be concentrated to generate heat for cooking?
   • Topic: Vermont is famous for maple syrup. → Testable Question: How does temperature affect the flow of liquid (syrup)?
   • Topic: California has earthquakes. → Testable Question: How can buildings be designed to withstand shaking?

   Write your final question in your science journal. This is the question your entire project will answer!

Part 2: The Lab - Designing Your Experiment or Model (Approx. 1 Hour)

This is where you put on your lab coat! Based on your question, we will design a project. This isn't about getting a "right" answer, but about exploring, building, and observing. In your journal, we will outline the following:

1. Hypothesis: What do you predict will happen? This is your educated guess. For example, "I predict that a building with a wider base will be more stable during a simulated earthquake."
2. Materials: Let's list every single item you'll need to build your model or do your experiment.
3. Procedure: Write a step-by-step guide for your experiment. Number each step so it's easy to follow. Think of it as a recipe for discovery!

Project Ideas to Spark Your Creativity:

• For Wyoming (Geysers): Create a "geyser in a bottle" using water, soap, and an effervescent tablet to demonstrate pressure release.
• For Louisiana (River Deltas): Build a model in a tray with sand and water to show how a river deposits sediment to create new land.
• For Kansas (Tornadoes): Make a "tornado in a bottle" with two plastic bottles and a connector to show how a vortex forms.
• For Hawaii (Volcanoes): Build a classic baking soda and vinegar volcano, but focus on explaining how it forms an island chain.

Part 3: The Expo - Data Collection and Presentation (Flexible Time)

Now it's time to run your experiment and share your knowledge!

1. Conduct Your Experiment: Follow your procedure carefully. The most important part is to be a great observer! Write down everything you see, hear, and notice in your science journal. Take pictures or draw sketches of the process.
2. Analyze Your Results: Look at your notes and observations. What happened? Did it match your hypothesis? Why or why not? What did you learn? Write a short paragraph in your journal summarizing your "Conclusion."
3. Create Your "Expo" Display: It's time to teach others what you learned! Create a presentation on your tri-fold board or in a slideshow. Make sure it includes:
   • The name of your state and your project title.
   • Your Testable Question and Hypothesis.
   • A brief list of your Materials and Procedure (pictures are great here!).
   • Your Observations/Results (include drawings or photos from the experiment!).
   • Your Conclusion: What did you learn, and how does this science concept apply to life in your chosen state?
4. Present Your Findings: Present your project to your family as if you are at a real science fair. Explain your process, demonstrate your model if possible, and answer their questions. Be proud of your work as a State Scientist!

Differentiation and Extension Ideas

• Go Deeper: Research a scientist from your chosen state who worked in a related field. Add a small biography of them to your presentation.
• Add a Challenge: Compare and contrast two states. For example, create one model showing how mountains are formed by tectonic plates colliding (like the Rockies in Colorado) and another showing how they are worn down by erosion (like the Appalachians in North Carolina).
• Tech Integration: Create a short video documentary of your experiment instead of a poster board, acting as the host of your own science show.
