Chemistry Lessons - Dissolving Salt & Sugar

Dissolving M&Ms (sugar) in water & alcohol

It's been a while since I've checked in about our chemistry class this year! Over the last month we've played with dissolving salt and sugar in water, alcohol and oil. We've discovered how the polarity of molecules affects how quickly the molecule can dissolve salt or sugar (if it can dissolve it at all).  Here's Mane in action:

We have continued to be very happy with MiddleSchoolChemistry.com! It's taken a lot longer to work through the lessons that I thought it would because we are doing every experiment and project in the lessons unless we absolutely cannot find materials. The early lessons were a breeze. The later lessons are more dense, and both Mane and I are getting a lot out of them! I'm understanding chemistry a lot better than I did in college!

Germanic American Institute

In early January we visited the Germanic American Institute in St. Paul for their Kaffeestube European Breakfast Cafe. It was Mango's birthday, and he'd been telling nostalgic stories about his trip to Germany in high school. German breakfast is something he always fondly recalls - dense breads, cold cuts, pickles, tomatoes, cucumbers, boiled eggs, yogurt & berries. And we were not disappointed by Kaffeestube:

After breakfast, we explored the building. The second floor houses a gallery. The current display is called Remembering Der Mauerfall and features photographs commemorating the fall of the Berlin Wall:

The library is full of books, games and movies in German!

A side sitting room was still decorated for Christmas...

The 3rd floor ballroom was very sweet!

The GAI hosts a number of events throughout the year, including German classes, discussion groups, parties, and dinners! In February they're offering a FREE yodeling class!! Check out their Events Page for more information.

Game Schooling - Xoom Cubes

We're still learning all the fun possibilities for game-play with Xoom Cubes, but already they are a giant hit at our house. I attended a Teacher Tuesday at Marbles: The Game Store, and I received this game for FREE!

Xoom Cubes is really just a box of alphabet cubes/dice in 4 different colors. One way to play: Each player gets a set of colored dice, rolls the dice, and creates words using as many of their letters as possible.

Variations include using a timer, creating a crossword, allowing re-rolling of unused dice, or pooling all the dice and racing to create words from the pool. Of course, the cubes could also be used with younger kids for matching letters and learning phonics!

Game Schooling - Puzzles

I know many seasoned homeschool parents who will say that their number one must-have homeschool tool is puzzles. And there's a fair amount of research about the educational value of jigsaw puzzles. Puzzles provide practice in deductive reasoning, categorization, analysis, sequencing, problem solving, spacial awareness, and scanning - skills that transfer especially well to the "academic" subjects of reading, math, and science. For the kinesthetic learner, puzzles can also be a hands-on way to work with subject matter. Example: We recently picked up a puzzle map of New York City. We'll be visiting New York this summer, and the puzzle is providing all of us with a hands-on way of familiarizing ourselves with the city.  We're developing a sense of the direction, distance, and general layout of places in the city. The puzzle is a conversation piece, as we discover street names and buildings, and it's a starting point for new learning about the city.

AND, "puzzling" is a fun social activity:

Game Schooling - Qwirkle

We added Qwirkle to the stack of games at our house over Christmas break this year. It came highly recommended from a educator friend, and is the winner of several game awards. I've heard is described as scrabble with colors and symbols rather than letters. MindWare describes the game in this way:

Qwirkle is as simple as matching colors and shapes, but this game also requires tactical maneuvers and well-planned strategy. Earn points by building rows and columns of blocks that share a common shape or color. Look for opportunities to score big by placing a tile that touches multiple pieces with matching attributes.

We've now played Qwirkle over and over (since our Christmas purchase), and every time we play, the high score gets higher! We're beginning to wonder how high it's actually possible to score in this game. One of the keys seems to be flexible thinking - the ability to shift from one plan to another and see all the various ways to play the same piece. There's also some balance to be had between cooperating with other players and throwing a wrench in the perfect rows and columns!

For serious Qwirkle players, MindWare has created Expansion Sets, Qwirkle Cubes (like the tiles, only multi-sided dice!), and Travel Qwirkle.

Game Schooling - Mancala

I've always found mancala to be such a beautiful and simple game. Who doesn't enjoy handfuls of gems? We used to play mancala with egg cartons when Mane was younger, but a friend gave us this lovely wooden mancala board last year!

Mancala is easy to learn and quick to play - deceptively quick and easy, for a surprising amount of strategy comes into play as players become more experienced. Dr. Gwen Dewar at Parenting Science describes mancala as a "count and capture" game that requires strategic mental planning, deductive reasoning and math skills. (For a blow-your-mind research paper on the mathematics involved in mancala, check this out: Mancala Games - Topics in Mathematics and Artificial Intelligence.) According to The Geek Parent, mancala may be the oldest board game in the world!! Clearly, this game has a lasting appeal. Wikipedia has a fantastic listing of various mancala games and links to their rules here: Wikipedia: Mancala Games.

And here's all you really need to get started (from education.com):

Also known as "count and capture" games, mancala games encourage kids to conduct thought experiments, counting tokens and comparing tactics in their heads before they move a game piece. Such qualities have inspired educators in Africa, Europe, and the United States to bring mancala into the classroom.

Does playing mancala actually sharpen math and thinking skills? To date, nobody has performed the relevant experiments to find out. However, competent performance requires counting and the mental movement of game tokens across a game board. And research suggests that good players use abstract or hypothetico-deductive reasoning (Retschitzki et al 1986). - See more at: http://www.parentingscience.com/mancala-games.html#sthash.xzhVgHdT.dpuf
