The Power of Plants! The Power of Plants!
Learning Objectives 1. Set up an experiment with two variables. 2. Make observations and record time variable data. 3. Create a graph from recorded data. 4. Interpret data and draw conclusions from an experiment.
What do all these things have in common? Your Home s Insulation A Down Jacket A Cooling Towel Regulates Temperature
Analogy: Down Jacket is to Your Body as ______ is to Earth? Bar-On, Phillips, and Milo (2018)
Plants Can Control Local Weather Take up and vaporize water Control local humidity and temperature Low albedo (reflection of solar energy); absorbs energy Evaporative cooling from transpiration
Materials 4 deep foil pie tins or shoe boxes 4 digital thermometers with max and min recording capabilities Small shovel and bucket Local soil Mulch Water Measuring cup Scale (optional) Ruler Layout of schoolyard with directional North and South Pen and paper Masking tape
