Hello! Welcome to Botany at CrabSO! We are so excited to have you! Do not start the test until you and your partner are ready. Please make sure you have one 8.5" x 11" sheet of paper. Stay on this tab the entire time as OOTB time will be counted You will have 50 minutes to complete this test Good luck!!

Welcome to Botany and we hope you like this trial event test! Special thanks to you for taking the test and to every single blade of grass I've ever seen!

Welcome to CrabSO!

Crabs love plants as much as you do (you love plants too)!! Blue crabs, native to our Chesapeake Bay (and delicious) eat a variety of plants. As you begin this test, you'll learn a bit more about them before you get into other (hopefully) fun questions about plants.

Question 1

1.75 pts

Yum.....grass...from the sea! Seagrass is another favorite for our blue crab friends! I want to know a bit more about this delicacy...what group does it belong to?

Passage

Now you've learned a bit more about the plants in the Chesapeake Bay and blue crabs (they're super cool and yummy...After the exam you can search up the incredible biodiversity in the Chesapeake Bay and the amazing system they've created)! Phew....time for the rest of the test, good luck!
