• Theme: Water Conservation and Sustainable Engineering
• Objective: Students design a rainwater capturing device that maximizes water collection, prevents evaporation, and incorporates geometric concepts.
• Duration: 3 weeks, 45 minutes per day
• Full Project: 3 weeks, 30-45 minutes per day
• Mini-Project: 5-7 days, 30-45 minutes per day
• Sprint: 2-3 days, 45-60 minutes per day

2. NGSS Standards Alignment

The project aligns with the following NGSS K-2 Engineering Design Standards:

• K-2-ETS1-1: Ask questions, make observations, and gather information to define a simple problem that can be solved through the development of a new or improved object or tool.
• Application: Students identify challenges related to water conservation and brainstorm solutions through device design.
• K-2-ETS1-2: Develop a simple sketch, drawing, or physical model to illustrate how the shape of an object helps it function as needed to solve a given problem.
• Application: Students create sketches and models of devices that effectively capture and store rainwater.
• K-2-ETS1-3: Analyze data from tests of two objects designed to solve the same problem to compare the strengths and weaknesses of how each performs.
• Application: Students test and evaluate different rainwater capture designs for efficiency and durability.
