Playing with chemical reactions is just too much fun to stop! So…we decided to have one last go at the gooey, bubbly world of creating chemical reactions with elements! We zoned in on two easy and high interest experiments today, as well as exploring the Supreme Court, through our dress-up theme. Lastly, we expanded our review time - to support all those in our group going for Memory Master (8 kids), by rotating through review stations for the various subjects.
Here Comes the Judge!
The kids had too much fun playing Judges! There were lots of pretend courtroom arguments over cases, and many objections flying around! It was lots of fun to see them act it out. We even decided to have them sit for a formal Supreme Court photo op! =)
Playing with PolymersWe began by exploring the element of boron, and what chemical reaction we could make with polyvinyl acetate (better known as Elmer's Glue). We took water, borax, glue, and food coloring (which I substituted with beet juice to eliminate the dyes). The reaction once you add the borax dissolved in water to the glue, is immediate, and very fun! This has an awesome feel and lasts for a long time. We then read about what a polymer was, and discussed what chemical reaction we just made. My kids loved this polymer and played with it repeatedly.
The assembling of ingredients...
Then the WOW!
Repeatable Lava Lamps!
So I say repeatable, because this one the kids can do over and over again, as many times as they like! How cool is that? All it took was 3/4 vegetable oil and 1/4 water, along with some food coloring and Alka Seltzer tablets! Viola! A lava lamp. (You could put it in a pretty glass bottle with a resealable cap, if you really wanted to get fancy!) The kids could then cap the mixture in the bottle and take it with them, along with the Alka Seltzer, to repeat the experiment for their Dad or friends. You can do it over and over again, by just adding the Alka Seltzer each time. Kinda cool!
Review Station Fun!
To provide for some extended review fun, we set up four stations to focus on four subjects for review this week. We had a Nerf ball station, magic cup station, bean bag toss station and alligator dentist game station. Each station focused on one subject for review, and the kids rotated around the stations at the blow of a whistle. They were given 3x5 index cards and they wrote down their points they won in each station. We assigned value to each activity. Points for each tooth pushed on the Alligator that didn't slap his jaws shut, points for each basket made, points for each correct guess of the magic cup station and points for each colored bowl the bean bag made it into.
Our theme for the snack was on dinosaurs, since our memory work for science was really on the theory of evolution (but who can pass up more chemistry fun!). So we had dinosaur eggs and some veggies for herbivores. Don't worry - we will be tackling the Evolution thing coming up, so stay tuned!
I hope you all had a very blessed and Wonderful Wednesday!
