In fact, September 16 is Collect Rocks Day. Yes, really! And what a great day for some rock talk. Did you know these fun facts about rocks and minerals?

*There are 3 major types of rocks: metamorphic, igneous, and sedimentary

*Rocks can change from one form to another

*Approximately 65% of earth’s rocks are igneous

*Petrology is the scientific study of rocks

*Diamonds, affectionately called ‘rocks’ are actually minerals. (Minerals are naturally occurring inorganic (not living) substances. Rocks are made up of two or more minerals and can include fossils)

*The mineral childrenite was named after, not children, but a man called John George Children

 

Your turn. This or That?

Rocky Road or mint chocolate chip ice-cream?

Rock n’ roll or hip hop?

Pebbles or Bam Bam?

 

Scavenger Hunt

Can you find at least one rock in each of these categories?

  1. Brown, yellow, or beige (example: brown chert, brown quartzite)
  2. White or light gray (example: white marble)
  3. Red, pink, or rusty (example: quartz rock)
  4. Black or dark gray (example: basalt, slate)

 

And now for something delicious in honor of this auspicious day!

Sedimentary Pizza Lasagna

Materials

1/2 pound (8 ounces) ground turkey or beef

2 cups pizza sauce

1 egg

1 cup ricotta cheese

Oven-ready lasagna noodles

Sliced pepperoni

1–2 cups shredded mozzarella cheese

 

Equipment

Frying pan

Spoon or spatula

Rectangular pan (8 x 10 inches or larger)

Heavy-duty aluminum foil

 

Method

  1. With an adult’s help, cook the ground meat in a frying pan until it is brown. Drain off any fat. Add the pizza sauce and mix well.
  2. Spread about 1/2 cup of the meat sauce on the bottom of the rectangular pan. Top with oven-ready lasagna noodles, overlapping slightly to cover the whole pan. Top with more sauce—about 1/2 cup.
  3. Crack and beat the egg, then mix thoroughly with ricotta cheese. Spread half this mixture over the noodles.
  4. Arrange a layer of pepperoni next, followed by a sprinkling of cheese. Top with a layer of lasagna noodles.
  5. Repeat the layers. Cover the final layer of lasagna noodles with the remaining meat sauce and a generous amount of mozzarella cheese.
  6. Cover the pan with heavy-duty foil. Bake in a 375°F oven for 45 minutes. Uncover and bake for another 10 minutes. Can you still identify the individual ingredients?
