A 52-Week Science Tour of the United States

Welcome, Jeaneth! This unit study is designed as a year-long, hands-on journey through the United States, exploring the unique science of each state. Each week, you will dive into a new state, focusing on its specific geology, ecology, meteorology, or technological innovations. The goal is not just to learn facts, but to understand scientific principles by *doing* science.

Below is the structure for each state's unit, followed by four fully planned examples (Alabama, California, Florida, and Alaska) to get you started. After the examples, you'll find a complete 52-week schedule with a suggested science focus for every state, Washington D.C., and a final capstone project week.

Week 1: Alabama - The Science of Biodiversity and River Systems

Materials Needed:

• For Project 1: Large clear jar or 2-liter bottle, soil, sand, gravel, pebbles, twigs, leaves, pond or stream water, small aquatic plants (optional), magnifying glass.
• For Project 2: Topographic map of Alabama (printable online), blue and green modeling clay or play-doh, cardboard or foam board base, small pebbles, craft glue.

Core Topics & Guiding Questions

Alabama has more freshwater biodiversity than any other state! We will explore why its rivers, soil, and climate create a perfect home for so many different species.

• Ecosystems: What is biodiversity? Why is the Mobile River Basin considered a biodiversity hotspot? How do different parts of a river (headwaters, main channel, delta) support different kinds of life?
• Geology & Soil Science: Alabama has a region called the "Black Belt," known for its dark, fertile soil. How was this soil formed? How does soil type affect what plants can grow and what animals can live there?
• Water Cycle & Hydrology: How does water flow through a watershed? How do human activities like building dams or farming impact river ecosystems and the organisms that live in them?

Hands-On Project Options

1. Build a River Ecosystem in a Jar (Mesocosm): Create a miniature, self-sustaining model of an Alabama river environment.
   • Step 1: Layer the bottom of your jar with gravel, then sand, and finally a layer of soil from your yard or a local park.
   • Step 2: Gently pour in water from a natural source like a pond or stream (with an adult's help!). This water contains microscopic organisms that will kickstart your ecosystem.
   • Step 3: Add small twigs, leaves, and maybe a tiny aquatic plant. Seal the jar.
   • Step 4: Place it in indirect sunlight and observe it daily for a few weeks. Use a journal to sketch the changes you see. What happens to the water clarity? Do you see any tiny creatures swimming? This demonstrates nutrient cycling and the interconnectedness of a habitat.
2. 3D Watershed Map: Construct a physical model of one of Alabama's major river systems (like the Coosa or Tombigbee River) to understand how water travels across the land.
   • Step 1: Print a topographic map of your chosen river basin.
   • Step 2: On your cardboard base, use green clay to build up the land, following the elevation lines on the map. Higher elevations should be thicker layers of clay.
   • Step 3: Use your finger or a tool to carve out the path of the main river and its tributaries, following the map.
   • Step 4: Use blue clay to fill in the river channels. You can use a spray bottle with water to simulate rain and watch how the water flows through your model watershed, collecting in the main river. This shows how pollution upstream can affect everything downstream.

Week 2: California - The Science of Plate Tectonics and Engineering

Materials Needed:

• For Project 1: Two large, flat crackers or graham crackers, a layer of frosting or peanut butter spread on a plate.
• For Project 2: Marshmallows (large and mini), toothpicks, a flat pan or cookie sheet to act as a "shake table."

Core Topics & Guiding Questions

California is a land of movement, from the shifting tectonic plates beneath the ground to the technological innovations in Silicon Valley. We'll explore the science of forces, both natural and human-made.

• Geology: What are tectonic plates? What happens at a transform boundary like the San Andreas Fault? How do earthquakes release energy and create seismic waves?
• Engineering & Design: How do engineers design buildings and bridges to withstand earthquakes? What principles (like cross-bracing and base isolation) make a structure more stable?
• Technology: How do scientists use technology like GPS and seismometers to monitor fault lines and predict potential earthquake hazards?

Hands-On Project Options

1. Edible Plate Tectonics: Model the three main types of plate boundaries using common kitchen items.
   • Step 1: Spread a thick layer of frosting (the asthenosphere) on a plate. The crackers are your tectonic plates (continental crust).
   • Step 2 (Divergent Boundary): Gently push two crackers apart. Notice how the "magma" (frosting) rises to fill the gap. This is how new crust is formed.
   • Step 3 (Convergent Boundary): Push two crackers together. One might slide under the other (subduction), or they might crumple up to form "mountains."
   • Step 4 (Transform Boundary): Slide two crackers past each other horizontally. Notice how they stick and then suddenly slip. This models the buildup and release of energy in an earthquake along the San Andreas Fault.
2. Earthquake-Proof Tower Challenge: Design and build a structure out of marshmallows and toothpicks that can survive a simulated earthquake.
   • Step 1: Using only marshmallows and toothpicks, build the tallest, most stable tower you can. Think about using triangles and wide bases for strength.
   • Step 2: Place your finished tower in the center of the pan (your "shake table").
   • Step 3: Gently shake the pan back and forth, gradually increasing the intensity. How long does your tower stay standing?
   • Step 4: Redesign! Analyze why your first tower failed. Was the base too narrow? Did you need more cross-bracing? Try to build a new, improved version. This mimics the iterative process of engineering design.

Week 3: Florida - The Science of Marine Ecosystems and Aerospace

Materials Needed:

• For Project 1: Large clear baking dish, sand, water, small shells and rocks, blue food coloring, vinegar, baking soda, small toy animals (crabs, fish).
• For Project 2: Film canister with a snap-on lid (ask at a photo developing store) or a small plastic bottle with a cork, Alka-Seltzer tablets, water, construction paper for fins and a nose cone, tape.

Core Topics & Guiding Questions

From the coral reefs of the Keys to the launch pads of Cape Canaveral, Florida is a place of exploration. We'll investigate the delicate balance of its marine life and the physics of escaping Earth's gravity.

• Marine Biology: What is a coral reef? Why are they called "rainforests of the sea"? What is the symbiotic relationship between coral polyps and algae? How does ocean acidification (the "evil twin" of climate change) affect coral and shelled organisms?
• Meteorology: How do hurricanes form over the warm waters surrounding Florida? What is the difference between a tropical storm and a hurricane?
• Physics & Aerospace Engineering: What is Newton's Third Law of Motion? How does a rocket engine generate thrust to overcome gravity? Why do rockets launch from places like Florida, near the equator? (Hint: It has to do with Earth's rotation!)

Hands-On Project Options

1. Ocean Acidification in a Pan: Create a model of a coral reef and see firsthand how a change in water chemistry affects it.
   • Step 1: In your baking dish, build a "seafloor" with sand, rocks, and shells (which are made of calcium carbonate, like coral skeletons).
   • Step 2: Add water and a few drops of blue food coloring. Place your toy animals in their habitat.
   • Step 3: Now, let's simulate ocean acidification. Vinegar is a weak acid. Slowly add a few tablespoons of vinegar to the water. What do you observe happening to the shells? You should see tiny bubbles forming on them as the acid reacts with the calcium carbonate, dissolving them. This is a simplified model of what's happening to coral reefs in the real world.
2. Build and Launch a Canister Rocket: Use a simple chemical reaction to demonstrate Newton's Third Law.
   • Step 1: Decorate your film canister to look like a rocket using paper fins and a nose cone. Make sure it can stand upside down on its fins.
   • Step 2: Go outside to an open area! Turn the rocket (canister) upside down so the lid is on the bottom.
   • Step 3: Fill the canister about 1/3 full with water.
   • Step 4: This is the tricky part! Drop half an Alka-Seltzer tablet into the water, quickly snap the lid on tightly, place the rocket on the ground (lid-side down), and step back several feet!
   • Step 5: The tablet will react with the water, creating carbon dioxide gas. The pressure will build until it pops the lid off, sending the rocket flying into the air! The downward force of the gas pushes the rocket upward (Action-Reaction).

Week 4: Alaska - The Science of Ice and Arctic Adaptations

Materials Needed:

• For Project 1: Two identical plastic food storage bags, a large bowl of ice water, shortening (like Crisco), a rubber band or tape.
• For Project 2: Large block of ice (freeze water in a bread pan or plastic tub), salt (coarse and fine), liquid watercolors or food coloring, eyedroppers or a small spoon.

Core Topics & Guiding Questions

Alaska is a land of extremes, with vast glaciers, frozen ground, and animals uniquely adapted to survive the cold. We'll explore the properties of ice and the amazing biology of the Arctic.

• Glaciology: What is a glacier and how does it form? How do glaciers shape the land, carving out valleys and creating fjords? Why are glaciers melting at an accelerated rate?
• Biology: How do animals like polar bears, arctic foxes, and walruses survive in extreme cold? What are adaptations? (e.g., blubber, fur, camouflage).
• Earth Science: What is permafrost? How does melting permafrost affect the environment, buildings, and the global climate (release of methane)?
• Physics/Astronomy: What causes the Aurora Borealis (Northern Lights)?

Hands-On Project Options

1. The Blubber Glove Experiment: Discover how a thick layer of fat (blubber) insulates arctic animals from freezing water.
   • Step 1: Prepare the ice water bath in the large bowl. It should be very cold!
   • Step 2: Place one hand directly into a plastic bag. This is your "control" hand.
   • Step 3: For the "blubber glove," turn one bag inside out. Scoop a large amount of shortening and smear it all over the bag.
   • Step 4: Turn the bag right-side-out again, so the shortening is now sandwiched between two layers of plastic. This is your blubber glove.
   • Step 5: Put one hand in the control bag and the other in the blubber glove. Submerge both hands into the ice water at the same time. Which hand gets cold faster? How long can you keep each hand in the water? You will feel a dramatic difference in insulation!
2. Glacier Salt & Ice Melt Art: Simulate how meltwater carves tunnels and channels through a glacier.
   • Step 1: Place your large block of ice on a tray or in a pan to catch the melting water.
   • Step 2: Sprinkle salt over the surface of the ice. The salt lowers the freezing point of water, causing it to melt wherever the salt touches it.
   • Step 3: Watch as the salt begins to create small tunnels, crevasses, and channels in the ice block.
   • Step 4: Use eyedroppers to drip different colors of liquid watercolor into the channels you've created. This allows you to see the intricate network of tunnels, similar to how meltwater flows through a real glacier. It's a beautiful demonstration of chemistry and geology.
