Post 9: This Week in Science (Fruit Flies Part 2)

          This week in science we figured out how many flies our fruit flies will reproduce in three weeks. We put six flies in our container , four females and two males. Then we fed our spider some wingless flies so it can survive while the others reproduce. Since we are still waiting for our flies to reproduce, we drop some wingless flies onto the spiders web so it can be able to eat while the others reproduce. We also observed our spiders terrarium and saw changes. Some plants are beginning to grow and theres moisture building up inside the terrarium.
          I learned that spiders reproduce fast. They can have as many as 20 eggs in one day. I also learned the number of flies that will be reproduced in three weeks, which would be 2,800 eggs. i also learned how to write it in a proper way. that would be, that if i out six fruit flies in a container, four female and two male, then there will be 2,800 eggs in three weeks because each female fruit fly produces 20 eggs per day.
