Study for Quiz Monday!

Please study:

• vocabulary words: matter, heterogeneous, homegenous, pure substance, dissolving, evaporation, solute, solvent, soluble, insoluble
• 5 separation techniques: settling, magnetic attraction, filtration, evaporation, chromatography
• classifying as an element, compound, or mixture (ex. water: is it an element, compound, or mixture)

This quiz is worth 40 points!!

Solubility

This week we are continuing with mixtures and talking more about solubility. I posted a powerpoint on Google classroom for reference and studying. A big point we are discussing in class is how solutions are mixtures. They are homogenous mixtures, but there are also mixtures that aren't solutions.

We are also looking at solubility graphs and interpreting them.

Vocabulary: saturated solution, unsaturated solution, supersaturated solution, soluble, insoluble, concentration, suspension

MIxtures

This week we will be concentrating on mixtures. They have recieved a couple handouts to use as references during this time. They have vocabulary and examples on them they should study and look over.

Vocabulary words: homogenous mixture, hetergenous mixture, suspension, colloid, solution, solute, solvent

They should know the 5 mixture separation techniques: evaporation, filtration, magnetic attraction, settling, and chromatography

We will be doing a very fun and involved lab with mixtures that will span a few days! I can't wait!

Please do not hesitate to email me with questions! allisonj@conwayschools.net

Vocabulary

Our class is struggling with vocabulary :-( Vocabulary is a HUGE part of science and the students can't get very far without knowing what our words mean. They should be taking notes in class and studying at night. I've noticed many think they can just hear it in class, but grades are proving otherwise.

Our students will be going to the junior high next year and we want to prepare them by making sure they take notes and study. Because they don't have a book they can bring home, there is even more reason to take LOTS of notes. We do have a class set of textbooks here at school and they have access during study hall, before/after school, lunch, and during class. If they need a book at any of these times they just need to ask and permission will be granted.

Vocabulary they NEED to study for Friday's Quiz on Elements and Compounds:

• Element
• Atom
• Compound
• Electron
• Proton
• Neutron
• Nucleus
• Chemical symbol
• Chemical formula (subscript)
• Molecule
• Atomic mass
• Atomic number
• Periodic Table-(families and periods of periodic table)
• Matter

Week 4: Elements, Compounds, Mixtures

This week we are starting our Chemistry unit! We will talk about elements, compounds, and mixtures. We will not memorize the Periodic Table, but students will have to know important elements like: carbon, hydrogen, oxygen, nitrogen.

I will be out on Friday, but our substitute is wonderful and I'm sure everyone will behave well for her.

Quiz tomorrow!

Know the difference between:

• Qualitative and quantitative
• Laws and theories
• Constant and control
• Observations and inferences
• Independent and dependent variables

STUDENTS: Go back through your labs and worksheets we did in class. Make sure you know the different pieces of our experiments. Study the vocabulary and notes we took in class. If necessary, get on classroom and re-watch some of the posted. All of these things can help you to do well tomorrow!
