Humdrum or delicious? When students eat their homework, the
classroom suddenly turns from tedious to oh-so-tasty. Get ready to serve up
some yummy new fun—while discovering and learning about math and science.
Psst, did you remember that Pi Day is March 14? It’s time to
divvy up some Variable Pizza Pi. Look up the recipe for this constant
crowd-pleaser in Eat Your Math Homework, and get set for variable
excitement—quite a lot . . . or mega.
Never mind the constants (the crust and the sauce), here’s
your chance to add your own variables: toppings such as pepperoni, green
pepper, or pineapple chunks. And we’re not done yet! Measure the circumference
and determine the diameter of the pizza. This will help you pinpoint pi, that
amazingly endless decimal number that starts 3.1415926 . . . (pi =
circumference divided by diameter)
What about in the classroom? How about switching things up a
bit with this yummy classroom adaptation? Share circle shaped cookies (Yes, the
cookie itself and the icing are the constants). Have students decorate each
cookie with variables such as chocolate chips, raisins, or colored
marshmallows. Figure out the circumference and diameter of one cookie (Hint: To
measure the circumference, use a piece of string. Place the string around the
rim of the cookie. Cut or mark the string to match the size of the cookie’s
circumference. Straighten this measured string and find its length using a
ruler).
When students find the circumference divided by the
diameter, it’s easy as pie to calculate pi. Was the answer close to 3.14? Why
wasn’t it exact? What else can you find out about pi?
And now here’s another tasty tidbit. Let’s face it, all
science lessons are not created equal. Neither are rocks. In fact, there are
three basic categories of rocks: metamorphic, igneous, and sedimentary. Heat
and pressure cause metamorphic rocks to morph, or change form. Igneous rocks
form from cooled liquid rock beneath the earth’s surface. And sedimentary,
well, think of a lasagna—when layers of sediment press against each other, the
layers meld together.
Speaking of lasagna, check out the recipe for Sedimentary
Pizza Lasagna from Eat Your Science Homework . . . Yum!
. . . Or whip up some classroom friendly Sedimentary
Sandwiches instead. Use 3 or 4 layers of bread (or crackers) and your favorite
sandwich fixings to build a rock solid masterpiece. Bite in—and don’t worry
about chipping a tooth!
