Your job here is to find out the lengths of these spacecrafts by measuring them. We've given you some rulers and other items (including Maggie!) that you can use to compare to the crafts and estimate their lengths.

Drag out rulers, spacecrafts and Maggies, line them up, and make your measurements! If your workspace gets messy, just drag things into the trash bins or use the CLEAR button to start fresh.

Enter your answer (and units!) in the box next to each spacecraft. There are six units you can estimate in for each craft. Every three that you answer will increase your clam salary by 1 clam!
