• Plants depend on water and light to grow. (2-LS2-1)
• Plants depend on animals for pollination or to move their seeds around. (2-LS2-2
ETS1.B: Developing Possible Solutions
• Designs can be conveyed through sketches, drawings, or physical models. These representations are useful in communicating ideas for a problem’s solutions to other people. (secondary to 2-LS2-2)
