This is my place for writing down ideas for teaching kids. You'll find things I have tried, things I am thinking about trying, and reviews of educational products. My own kids are young so most of the information is for preschool age children. I hope you find it useful.
Okay, here is the gak recipe I promised. Seriously fun to make and the kids play with it forever. I got the recipe and the picture here. So if you are looking for more detailed directions look there. But here is basically how it's made.
Take one 8 oz container of Elmer's Glue-All. Dump it into a bowl. Refill the bottle with water and dump that into the bowl as well. Mix them together.
In a separate bowl or cup, mix 1/2 cup warm water with 1 tsp Borax. It doesn't have to mix completely, just kinda mix it around. Then gradually mix the borax solution into the glue solution. Your kids will want to have their hands in the bowl to help mix, and to feel the gak form. It happens immediately and is really fun to play with as it does. Roll the ball of gak around in the bowl and knead it a bit to let all the glue solution interact with the borax. That's it! Really easy and really fun!
1. I had never heard of Borax before about a month ago and now I am seeing recipes calling for it all over the place (I even used it to make my own laundry detergent recently). It is pretty easy to find in the laundry section of most stores. Short of that you might try Amazon. It's cheap too. I big box cost me about $2.
2. This stuff generally cleans up pretty easily if you soak it with water, but Last time I made it I decided to dye it bright purple. That made it a bit more messy, so... color at your own risk.
3. Thing1 and thing2 had a friend come over and play with them. She had the fun idea to stick dried beans in the gak. That gave it an interesting texture. Kind of fun.
4. You can store this in a Ziplock bag, but my experience has been that it gets dirty pretty fast so I've never been able to keep it for more than a few days.
