Dobbs’ Deep Sea Divers
September 25, 2017
Hello everyone,
This week in Social Studies, we will continue studying the Age of Discovery. Students will be learning specifically what motivated Europeans to explore and colonize the New World. They will be studying what is known as the Columbian Exchange, which is the name given to the increase in trade between the New and Old World. Students will be bringing home the TN Studies Weekly newspaper this week with the homework assignment of completing the crossword puzzle. This assignment should be turned in by Friday.
In science, we will focus on the standard of distinguishing the difference between complete and incomplete metamorphosis. Please study the following vocabulary for the test on Friday. Use the diagrams on the back to help your child study.
life cycle: all the stages that an organism goes through from birth to death
reproduction: making more of one’s own kind
complete metamorphosis: a total change in form as an organism becomes an adult. Each stage looks much different than the other. Its life cycle consists of an egg, larva, pupa and adult stage. The best example is the life cycle of a butterfly.
larva: The second stage of complete metamorphosis. This stage usually looks like a caterpillar.
pupa: the third stage of complete metamorphosis. This stage is a cocoon in the butterfly’s life cycle.
incomplete metamorphosis: this life cycle is where the organism keeps the same basic body shape as it grows into adulthood. The best example is a cricket or grasshopper.
nymph: the second stage of incomplete metamorphosis. In this stage, the organism looks like the smaller version of its adult form.
Please sign and return this letter to receive an additional five bonus points on your
science test this Friday.
