The phrase of the day was: Chemical Reaction!
We have been immersed in our science unit. I have been trying to make it as hands-on as possible, while simultaneously deepening their understanding of what and why things happen. The following were simple, yet purposeful in providing practice writing chemical reactions and formulas.
Activity #1 Green Chocolate-Chip Pancakes
Students wrote down the reactants and then wrote the products. We discussed what we started with and the precipitate we ended up with--and the best part was that we got to eat them as well!
Activity #2 Gak
I love science! I am fascinated by how it increases curiosity, engages the mind, and develops a sense of inquiry. One of my favorite science people of all times, is Steve Spangler. He has this absolutely awesome website with tons of experiments you can do with your kiddos. There are of course tons of items you can buy off the store website that are so cool (I am definitely guilty of that), but not necessary. Simply click on the picture below for complete directions and explanation of the what/why.
Activity #3 Green Play-dough
This activity came from Rockabye Butterfly. It was so simple and they loved smelly it. The complete directions are on the site.
[Explanations: The flour, salt, water, and oil are combining to form a new substance. They cannot be separated back into their original substances or states because a chemical reaction has occurred creating a dough with a puffy, stretchy, pliable texture. Foods, fabrics, plastics, fibers, gels, rubber, and gooey stuff are all materials that form chains of molecules called polymers. Polymers are solids because they hold their shape even though it is stretchy or pliable.]
Activity #4 Borax Shamrock Crystals
I know this is NOT a chemical reaction. It is a suspension which is a type of mixture, but I knew it would be a great review of mixtures/solution. The picture below is linked back to Steve Spangler's site on how to do it and the explanation. All we did is shape the pipe cleaner into a shamrock. Steve says to use white pipe cleaners and food coloring. We used green pipe cleaners and no food coloring. Within an hour you could see the formation of crystals on the pipe cleaner. My kiddos were blown away at what they were observing.
We ended our celebration of St. Patrick's Day by eating some yummy green sauce nachos. I have to admit they looked a little weird, but as you can see by my kiddos' faces, they enjoyed them.
Even though many of these activities can be done with much younger children, the science behind them was perfect for our chemical reactions (mixtures/solutions) unit. I take many things for granted and sometimes assume that my kiddos have had exposure to many of these activities at home, but the reality is that most had never done any of these before. They were so captivated, engaged, and above all having lots of fun learning.
