Students must be able to read and interpret a station model for the test! This station model says that it is 57 degrees Fahrenheit, 25% cloud cover, wind blowing northwest at 54 km/h, and the pressure is 1070 millibars.

Vocabulary for our unit: air mass humidity relative humidity wind shear tornado front (cold, warm, stationary) warning watch meteorologist isobars isotherms hurricane station model air pressure hail fog sleet snow condensation nuclei blizzard typhoon cyclone

Radiation is the transfer of energy by electromagnetic waves. It is the transfer of energy through space, The source is mainly the sun, but can also be microwaves. Convection is the transfer of heat by the flow of a heated material. It usually occurs in gases and liquids. Conduction is the transfer of heat through contact. It usually occurs through solids.

Where we live in the U.S., the Prevailing Westerlies are responsible for much of the movement of weather. The doldrums are a windless zone near the equator. Steady winds between the equator and 30 degrees north or south are known as the trade winds. The air currents that blow near the North and South Poles are the Polar Easterlies.

Vocabulary for the unit should be defined in the student's notes. (book chapter 4 is on google classroom) atmosphere troposphere hydrosphere ozone layer ultraviolet light  chlorofluorocarbon (CFC) conduction convection radiation condensation coriolis effect jet stream land breeze sea breeze Student's have a foldable on the atmosphere as notes to study as well as a powerpoint presentation printed on paper. This  is a great site for information and a good study tool. 

Write your answers on your own paper. 1. Define speed, force, inertia, gravity, and acceleration. 2. What are the 4 types of friction? 3. What does friction do? 4. How is weight determined? What makes it different from mass? 5. What is Newton's 1st Law? Give an example. 6. What is the difference in a balanced and unbalanced force? 7. What is the 2nd Law of Motion? Give an example. 8. How does mass and force affect acceleration? 9. How is mass, force, and acceleration related? 10. What is Newton's 3rd Law of Motion? Give an example. 11. How is friction useful? 12. How is gravity related to the 2nd Law of Motion? If you have not watched the videos on Google Classroom, please do so. I also have link below to some videos and review questions. Please click through, watch, and study!

http://www.scholastic.com/teachers/activity/force-and-motion-6-studyjams-interactive-science-activities This site has some fun little videos and explanations of Newton's Laws.

Newton's 1st Law states that an object in motion stays in motion and an object at rest stays at rest until acted on by a force. Newton's 2nd law has to do with force, acceleration, and mass. It really means that if you increase mass then acceleration will decrease (of course because it weighted down) and if you increase force, acceleration will increase. They are all related in a formula: Force=mass x acceleration. An example would be if a pitch a baseball it will go faster than if I tossed it gently because I put more force behind the pitch! Also, heavier things require more force to accelerate like the illustration below.                       Newton's 3rd law says that for every action there is an equal and opposite reaction. The best example of this is a rocket launch. The gases combust out the bottom of the rocket and in turn the rocket gets pushed up in air. Equal and opposite forces!                       

I've found a way to post the chapters from the book we use in class to Google Classroom. I put Chapter 24 up today in the 'About' section. The students can use it to study this weekend! I will continue to post the chapters we use in future units, but they must also continue to study all classwork, activities, and notes since the questions don't all come from the material in the book. I'm glad we can have this resource since I am unable to send a book home with each student.

Be able to tell what an element, compound, and mixture are.  Be able to read and tell how many atoms are in a compound. (Ex. CO2-This means the element has 1 carbon atom and 2 oxygen atoms) Know at least 5 compound and their chemical formulas (Ex. NaCl is sodium chloride, H20 is water) Students must know the 5 separation techniques and how to use them. They are settling, filtration, magnetic attraction, evaporation, and chromotography. What is the difference between homogeneous and heterogeneous mixtures. Be able to tell which is the solute and solvent in a solution. What 3 things affect the rate of solubility? Students must know elements combine to make many different substances in the world.  How to read/interpret a solubility graph. What is the "universal" solvent? How does pressure affect the solubility of a liquid-gas solution? Be able to name 3 elements and their chemical symbols. Study all vocabulary, handouts from class, and notes taken in class. 

Next week we are beginning the study of elements and compounds. Students will be able to explain how a small number of naturally occuring elements can result in the variety of substances found in the world. Studentst will also be able to classify substances as elements or compounds. There are between 88-92 naturally occuring elements on Earth These elements form many different molecules and compounds, like H20 and CO2 2 or more elements combine chemically to form compounds C + O + O = CO2 (carbon dioxide) H + H + O = H20 (water) Na + Cl = NaCl (sodium chloride-table salt) There are a huge number of possible combinations of elements to form compunds and mixtures ELEMENTS-pure substances that make up all matter, cannot be separated  Elements are organized inthe periodic table. Each element has its own symbol. Some elements and symbols students should know and be familiar with: Carbon (C), Hydrogen (H), Oxygen (O), Iron (Fe), Nitrogen (N), Sodium (Na), Argon (Ar), Helium

We will be having our first test on Thursday, September 1st. It will be over the Nature of Science. Items to study include: Hypothesis Dependent Variable Independent Variable Experimental Group Control Group Constants Data (qualitative and quantitative) Classify-put into groups Infer-to conclude from evidence difference in laws, theories, and hypothesis Your child should be studying what we've done and notes they've taken in class.  We are still learning new material Monday and Tuesday. The study guide will be on Google Classroom and they will work on it in class Wednesday. 

Welcome parents and students! We are back to school in full swing and ready to learn. I'm very excited to have each student in my class this year. I know God has put us together for a reason and I don't that job lightly. I will pray for your student and love them as much as I can. I hope we can have an excellent year. Seventh grade is a difficult time in every young person's life. There will be times they mess up, don't turn in work, forget supplies, etc. Hopefully we can work together as they mature and grow this year.  Please do no hesitate to email me. It is the fastest way to communicate with me. I also will try to post weekly on this blog to keep you in the loop about what is going on in science. Please subscribe to my Remind by texting  @eec738 to 81010 for Science OR  @abakd to 81010 for Pre-AP Science. I look forward to getting to know your child! 

Ruth Doyle Middle School 7th Grade Science 2016-2017 Contact Info: Jalisa Allison 450-6675 allisonj@conwayschools.net Course Description: We will be exploring methods, technology, and lab safety that scientist use. As a student in this class you will be asked to analyze and complete inquiry based assignments surrounding the topics of: plants, vertebrates, human body, life cycles, reproduction, heredity, cells, matter, solutions, atmosphere, motion, forces, energy, weather, seasons, planetary rotation and revolution. Students will gain a better understanding of the world around them. Student Responsibilities and Information : Students will adhere to classroom rules in order to create a class where students can think and share their ideas. Students will be prepared with assignments and materials. Assignments need to be turned in ON TIME and materials brought to class each day. Students will respect the teacher, students, and guests. It is easy to respect t
