Today we worked on the first part of our concentration investigation by making observations about drink mixes. Students were given two sets of drink powder/water solutions of different concentrations to observe. Student observations are below. Tomorrow we will discuss and take notes on what concentration means and some ways to determine if one solution is more concentrated than another.

Today we logged into a new website/game called Prodigy. Both classes LOVED it. The premise is like Pokemon (earning points that allow you to gain strength/potions/etc) that you use in wizarding battles. I have assigned a standardized test prep for students to work on over the next week. The questions are imbedded in the game as students play. I get data on the number and types of questions that students are successful/unsuccessful on. The bonus is that you can too! Each student has their login sheet and gives you the basic directions from the website www.prodigygame.com/NewParent.
This new resources was shared by other teachers using it in our school with high engagement and great data being collected. Homework tonight: complete 20 (or more!) minutes of Prodigy :) Today we had part of our class working with subtracting mixed numbers with problems that needed to be regrouped. This is one of the most challenging skills conceptually and will be worked on for several days. The other group worked on multiplying simple fractions with a focus on cross-cancelling (simplifying before multiplying).
Homework tonight: SHOW WORK Subtraction: PS6 worksheet Multiplication: page 92 Today we reviewed our final saturation experiment from before break and confirmed that our mystery chemical was Epsom salt. Students were able to use the mass data that they collected to compare it to the list of given chemicals to determine the correct chemical. Students also drew the evaporate Epsom salt crystals in their science notebooks. Tomorrow we start our investigation into concentrations of solutions.
Today students used their understanding of how to determine the amount of a solute needed to saturate a solution to figure out what a mystery chemical is. Some groups were not able to finish today but will do so tomorrow.
We continued our Olympic Math with 5 new medal comparisons. Students are getting really good at converting between fractions and decimals/percents. The remainder of the class was devoted to practice with adding and subtracting. Tomorrow's class is going to be fraction bingo.
Homework: complete classwork group 1: C46 "How do Mountains Breathe?" group 2: C49 "Why do Mermaids wear Goggles?" We continued our work on saturation with a lab to saturate 50 ml of water with citric acid. Students found that it took a lot more citric acid to saturate the water than Kosher salt. Students reinforced their understanding of how to determine if a solution is saturated. Students used their vocab foldable to study for their quiz, taken today. Tomorrow groups will try to determine what a "mystery chemical" is by how much it takes to saturate 50 ml of water.
Students worked to practice and master the skill that they learned yesterday. One group worked on subtracting simple fractions with unlike denominators, and the other group worked on subtracting mixed numbers where some required regrouping. Both groups had a page of adding or subtracting mixed numbers as an extension or review if they finished the classwork assignment.
These class work worksheets will be due on Tuesday of next week. Homework: complete assigned side of worksheet: either page 18 (subtracting simple fractions) or "Pet Show" (subtracting mixed numbers)- Excursion is not required **The back side is not homework, but can be completed if desired We started a vocabulary review page today with the words that we have already talked about in our Mixtures and Solutions unit. Students are creating a drawing to help them remember the definition of each word and then writing the definition on the back. This will be a useful study tool as we continue through our unit.
