2009/10 Program Schedule
- 41. The Case of the Wacky Water Cycle
-
- 101. The Case of the Unknown Stink
- By learning about the sense of smell, wind speed and direction, and NASA's atmospheric research, the treehouse detectives discover the source of an unpleasant odor in their neighborhood.
- 102. The Case of the Barking Dogs
- Why are dogs in surrounding neighborhoods barking early in the morning and late at night? The treehouse detectives answer the question using scientific inquiry, logic, and facts about sound.
- 103. The Case of the Electrical Mystery
- When the electricity goes off in neighborhood homes but stays on in the treehouse, the detectives solve the mystery by learning about electrical currents, circuits, and distribution.
- 104. The Case of the Challenging Flight
- The detectives compete with students from a rival school to see who can build the best model airplane. In the process, they learn about lift, thrust, drag, and gravity—the four basic components of flight.
- 201. The Case of the Mysterious Red Light
- After noticing some unusually bright-red sunrises and sunsets, the treehouse detectives research the atmospheric conditions that create these spectacular sights.
- 202. The Case of the 'Wright' Invention
- While trying to perfect an invention of their own, the treehouse detectives travel back in time to get some expert advice on the process of invention from two brothers who know a lot about it: Orville and Wilbur Wright.
- 203. The Case of the Inhabitable Habitat
- The treehouse detectives enter a contest to design a habitat that can keep humans alive on Mars. Before starting to work on their design, they decide they need to learn more about the planet Mars as well as various habitats here on Earth.
- 204. The Case of the Phenomenal Weather
- While planning a trip to the Caribbean, the detectives learn just how unpredictable predicting the weather can be. In the process, they learn about violent storms like hurricanes and tornadoes, weather fronts, global wind patterns, and climates.
- 301. The Case of the Powerful Pulleys
- One of the detectives has an accident and can no longer get into the treehouse. Using problem-based learning, the others investigate the worlds of simple machines and physical science and figure out a way to pull their friend in.
- 302. The Case of the Shaky Quake
- Troubled by a strange tremor in the area, the young detectives investigate the cause, exploring the science behind earthquakes by delving into geography, geology, and plate tectonics.
- 303. The Case of the Biological Biosphere
- The treehouse detectives learn about the world inside the human body.
- 304. The Case of the Galactic Vacation
- While creating travel brochures advertising vacations throughout the solar system, the treehouse detectives confront questions like what to pack for spring on Saturn or a weekend on Jupiter.
- 401. The Case of the Wacky Water Cycle
- The kids' attempt to raise money with a car wash dries up when the city is hit with a summer drought. Using problem-based learning, they learn all about the water cycle, the water table, and global climates to get their project flowing again.
- 402. The Case of the Disappearing Dirt
- When they discover that their favorite patch of beach is shrinking, the treehouse detectives dig into the topics of erosion, rocks, and natural preservation to save it.
- 403. The Case of the Prize-Winning Plants
- The kids test their green thumbs by growing plants for a fair. The treehouse becomes a greenhouse as they explore soil composition, plant and animal life cycles, and genetics.
- 404. The Case of the Radical Ride
- The kids' project on alternative forms of transportation takes on new relevance when they get caught in a traffic jam. In search of hassle-free traveling, they explore the principles of energy production and consumption, composite materials, and new technologies.
- 501. The Case of the Great Space Exploration
- The treehouse detectives set out to learn what it would take to become a space explorer.
- 502. The Case of the Ocean Odyssey
- Floating tennis shoes and oil globs washing up on beaches inspire an exploration of life in the sea. The kids dive into studies of ocean floor topography, currents, and ocean zones.
- 503. The Case of Zany Animal Antics
- Curious about why some animals are acting a little differently, the treehouse detectives investigate how animals are classified as well as their life cycles, migratory patterns, and habitats.
- 504. The Case of the Technical Knockout
- The kids discover that high-tech devices have their downside when the treehouse is hit with a blackout. Eager to get to the bottom of things, they follow the wind to the nearest star: the sun.
- 601. The Case of the Fitness Challenge
- Eager to win the Presidential Physical Fitness Award, the treehouse detectives research muscles, bones, and physical activity to learn how to get and stay fit.
- 602. The Case of the Mysterious Material
- When the kids find an unusual object right under their feet, they initiate a Crime Scene Investigation Team to figure out what it is and where it came from.
- 603. The Case of the Energy Crunch
- An electrical brownout prompts the detectives to learn about energy. While investigating various resources, they discover why conservation of energy is important.
- 604. The Case of the Deafening Sound
- A friend asks the kids to help solve a problem involving noisy aircraft. NASA scientists help them learn about how sound travels, how humans hear, and what is being done to make the skies quieter.
