I bought some plants from our SAR science class (which is growing them for a fundraiser).
My first foray into gardening was to repot some of these plants into bigger pots.
Math Problem Ideas
1) Convert the weight of potting soil (which comes in 35.39 L bags) into pounds.
2) Estimate the appropriate pot diameter to buy for plants and explain rationale for choosing them.
3) Estimate how many of the small basil plants to buy if you want to make a caprese salad for your class.
