Standard K.1.1
Obtain, evaluate, and communicate information about local, observable weather conditions to describe patterns over time. Emphasize the students' collection and sharing of data. Examples of data could include sunny, cloudy, windy, rainy, cold, or warm. (ESS2.D)

Standard K.1.2
Obtain, evaluate, and communicate information on the effect of forecasted weather patterns on human behavior. Examples could include how humans respond to local forecasts of typical and severe weather such as extreme heat, high winds, flash floods, thunderstorms, or snowstorms. (ESS3.B)

Standard K.1.3
Carry out an investigation using the five senses, to determine the effect of sunlight on different surfaces and materials. Examples could include measuring temperature, through touch or other methods, on natural and man-made materials in various locations throughout the day. (PS3.B)

Standard K.1.4
Design a solution that will reduce the warming effect of sunlight on an area. Define the problem by asking questions and gathering information, convey designs through sketches, drawings, or physical models, and compare and test designs.(PS3.B, ETS1.A, ETS1.B, ETS1.C)

🔬 Science & STEM

• Pizza Box Solar Oven: Construct a working outdoor cooker using a cardboard box, aluminum foil, and plastic wrap to explore solar energy.

• Tornado in a Bottle: Swirl two connected plastic bottles to visually simulate fluid dynamics and weather systems.

• Acid-Base Volcanos: Combine household vinegar and baking soda to witness chemical reactions through fizzing carbon dioxide gas.

• Strawberry DNA Extraction: Mash fruit and use basic household solvents to isolate visible genetic material. [1, 2, 3, 4, 5]

📐 Math & Engineering

• Toothpick & Marshmallow Towers: Design and construct structural models to test stability, load-bearing capability, and geometric balance. [1, 2, 3, 4, 5]

• Circumference Baking: Measure the diameter and calculate the circumference of real cookies, pizzas, or pies before eating them. [1, 2]

• Balloon-Powered Racers: Build small vehicles out of recycled plastic bottles and use escaping balloon air to study propulsion and physics. 

1. Weather Dress-Up Relay (Typical & Extreme Weather)

• Concept: Choosing appropriate clothing based on a daily forecast.

• Materials: A large box of clothing items (raincoats, winter coats, sunglasses, sun hats, mittens, boots, umbrellas).

• Action: Project a weather forecast on the board (e.g., "Tomorrow will be a heavy snowstorm!"). Have students race to select the correct gear humans need to stay safe and comfortable.

• Discussion: Ask students why we check the forecast before leaving the house

Investigation 1: The "Sunny vs. Shady" Touch Walk (Sensory Exploration)

Students use their sense of touch to compare identical materials placed in different lighting conditions. 

• Materials: Access to an outdoor area with both direct sunlight and deep shade. [

• The Action:

  1. Take the class outside during a sunny morning or afternoon.

  2. Find a spot where a single material spans both sun and shade (such as a concrete sidewalk, a patch of grass, or a metal handrail).

  3. Have students use the back of their hand (a sensitive area for temperature) to touch the concrete in the shade, then touch the concrete in the sun. [1]

•      Climate inquiry: The temperature of Earth's surfaces You may have noticed running around barefoot in the summer that you can comfortably walk across the grass, but roads and sand can be way too hot! As the sun's energy warms the earth, it doesn't heat evenly. Different surfaces absorb different amounts of the sun's energy. The more of the sun's energy surface absorbs, the hotter it gets. 

To reduce the warming effect of sunlight on an area, you must block, reflect, or absorb solar radiation before it hits the ground. This engineering challenge addresses Next Generation Science Standards (NGSS) Standard K-PS3-2 (often adapted locally as K.1.4), which focuses on using tools and materials to design and build a structure that reduces the warming effect of sunlight.

Here is a comprehensive guide to designing, testing, and understanding an effective sunshade solution.

1. Choose Reflective Materials

• White paper/cardstock: Reflects visible light effectively.

• Aluminum foil: Reflects both visible light and infrared (heat) radiation.

• Mylar sheets: High-efficiency reflective barrier used in space blankets.

• Light-colored fabrics: Scatters sunlight while allowing airflow. 

2. Build a Prototype Structure

• Canopy/Umbrella: Suspend a reflective sheet using wooden skewers or straws to create an elevated roof.

• A-Frame Tent: Angle two reflective panels together over the target area to deflect angled morning and afternoon sun.

• Layered Roof: Place a layer of aluminum foil slightly above a cardboard roof, leaving an air gap to prevent conductive heat transfer. [1]

3. Test and Measure

• Control setup: Place a thermometer directly in an open, unshaded area under the sun or a heat lamp.

• Experimental setup: Place an identical thermometer completely underneath your prototype structure.

• Data collection: Record the temperature of both areas every \(2\) minutes for a total of \(10\) minutes to track the warming trend
