Grade 8: Week of March 26th to 30th
Our new chapter is about exposure to chemicals. We will explore acute versus chronic exposure to chemicals, how chemicals enter our body through inhalation, ingestion, and absorption, and the difference between dose and concentration. We will discuss the threshold and potency of chemicals, and individual susceptibility based on factors such as age, gender, and lifestyle. Students will learn about chemical exposure through discussion of common chemicals in poison ivy, fried chicken, and vinegar. They will also explore chemicals they are probably not as familiar with such as dioxins, DDT, and mercury. Please note I am being quite strict about homework, and students will receive a detention slip to stay after school Wednesday if they do not complete Tuesday night's study guide homework.
Homework for the week:
Monday night: Study guide of pg. 343 words: definitions and examples (no examples for FDA, EPA, and toxicologists), pg. 343-344 Multiple choice #1-9
Tuesday: pg. 354 Review #1-3, Reflect #1-2
Wednesday: Homework: continue the study guide of words in bold in the text from exposure to metabolism
Thursday: Fill in the chart completely with two other chemicals of your choice. The first two chemicals were completed in class as model examples.

Grade 5: Week of March 26th to 30th
At the same time we are learning about ecosystems, we will begin reviewing for the EOGs. Mrs. Barbour has ordered our EOG books. In the meantime, we will learn about one lesson at a time during the beginning of class. Students will also have EOG vocabulary words and will write definitions, draw pictures, and make sentences for each one. 5A will do these vocabulary words during Thursday class time and for homework. 5B and C will have these vocabulary words for homework Wednesday and Thursday and will receive instruction on them Wednesday.
Homework for the week:
Monday night: Research the temperature and precipitation of each ecosystem: the rainforest, grassland, tundra, taiga (coniferous forest), and deciduous forest. See google images for each ecosystem.
Tuesday: Competitive Edge Pg. 66 #1-5; those retaking the Landforms test need to restudy tonight. Students will retake a mini test on Wednesday on those questions most students missed.
Wednesday: pg. 67-68 #10-15; Pictures and sentences for the words: abiotic, abrasion, air mass, air pressure, balanced forces, biotic, canyon (5B, 5C only). Students will receive a sheet with definitions.

Grade 5: Week of March 19th to 21st
You will receive an email or letter from me this week about EOG coach books. I would very much appreciate if each parent could purchase an EOG coach book for Science. It will cost only $6.00 and students will use it on a regular basis to prepare for the EOG exam. It has mini-lessons, questions very similar to the EOG, and EOG practice tests. I will assign homework from the EOG coach book and we will do exercises in class and during remediation time. The cost break down of the book is the following: $4.99 + 12% for shipping + 6.75% NC sales tax/per book = $5.93 + 5.95 shipping and handling per order. I will pay the remainder of the shipping and handling so we can keep the book cost at an even $6.00. Please have the money in by Wednesday March 21st so we may order the books.
Homework of the week:
Monday: Study for the Nine Weeks Landform test
Tuesday: Read pgs. 83-85 and answer questions on pgs. 94-95 #1, 3, 4 in the Competitive Edge
Grade 6: Week of March 19th to 21st
*Please note that students only have until Wednesday to retake any Science test below 70% and then this grade will go on the report card.

China trip
Unfortunately two people needed to cancel their trip to China, and we have two spots left. We will visit Beijing, Xi'an, and Shanghai over spring break from April 6th to 14th. Some highlights are the Great Wall of China, visiting a Chinese school, the world trade center in Shanghai, Terracotta Warriors, the Forbidden City, and eating a traditional dinner with a Chinese family.
If you are interested in visiting China with us you may contact me at crennie@neusecharterschool.org. The cost of the trip is approximately $3000 and includes flights, domestic flights, hotels, tours, breakfast, and dinner.
Work days and report cards
Friday March 30th is report card day.
