Science 9 - Students started the ecology unit today in class. Students read a short section on pages 20-21 and were asked to answer questions 1 & 3 on page 21 and another question from class. Students now have copies of the grade 9 and 10 science textbooks. Students only need to bring the science 10 textbook with them to class until exam reviews start. Students are asked to keep the science 9 textbook in a safe place as not to lose it.   Biology 112 - Students learned about the phylum platyhelminthes and phylum nematoda today in class. Students will have another warmup tomorrow, followed by a section on the phylum annelida. Earthworm dissections will take place on Monday.
