5E Lesson Plan: Life Cycle of a Plant

I am creating a 5E lesson plan for second grade on a plant's life cycle. For the Explore section, i decided to create an activity where my students can work in pairs and grow their own plant. Each group will have a different set up for their plant. For example, one group will grow their plant without any sunlight and see how that affects the plant's growth. What are other ways plant growth can be affected that my students can test? I have lack of water, lack of sunlight, and watering the plant with another liquid (like juice) rather than water.

Temperature could also be used as a variable by some teams trying to grow a plant on a candle warmer or other low fire-hazard heat source.

Hi. Lack of soil since soil provides most of the nutrients that aren’t in water. To make it more valid, use distilled water that will reduce the liklihood of nitrogen, magnesium, phosphates and potassium. Also consider using fertilizer which contains nitrogen, phosphorus and potassium.  You can also change pH... ex: use tea, soap and that juice. Most juices are acidic - the citrus ones are around 1-2 ph, soap is more basic say 8 or 9 and tea is closer to neutral like water.  I actually tested this for my high school class recently... so I could develop a lesson using household items, that way students can bring in the materials! 

Add some food coloring, and you can show how water moves from the roots to the leaves too!

Oh, forgot, use compost... that can be your fertilizer. Used coffee grounds contain nitrogen, and banana peels contain potassium.
