I've been having a fantastic time meeting early childhood educators and professionals all over the U.P. of Michigan! One of my most popular training sessions this summer has been "It's Not Rocket Science, but Sometimes It Feels Like It!" We have been working to break down the fear barrier that is sometimes associated with science, and to build confidence in scientific exploration. One of the great things about this training is that participants walk away with this great kit from Learning Resources: (courtesy of the Great Start Regional Child Care Resource Center)
As much as I am loving presenting, sometimes I think that some of the children enrolled in my care could do just as good, if not a better job in teaching this topic! They have mastered the science kit, and have been having a great time exploring extension activities.
We LOVE to play with vinegar and baking soda! One of the fun extension activities with the science kit is to blow the cork off of the flask. Now, it took me a little while to figure out how to perfect this technique..... but we finally have it down to a science ;).
First, you use the funnel to pour some vinegar into the flask. We haven't been the greatest at measuring, so just pour some in so that you have about an inch in the bottom of the flask.
Then fill the cork about 1/2 way with baking soda.
Then..... here is the most important step..... place a cotton ball in the top of the cork. This is going to keep the reaction from happening too fast and will allow you place the cork on the flask before the reaction starts.
Place the cork on top of the flask. Gently tap it until the cotton ball falls down into the vinegar. Step back and wait......
Of course, our "playing" with vinegar and baking soda did not end with cork blowing......
We made quite a few baggie bombs..... and another giant dinosaur volcano........
Each and every dinosaur needed to be placed just right before the volcano erupted!
The oozing lava looked so inviting.... that..... the children wondered..... what does it feel like?
I don't know..... let's find out!
What kind of explorations have you been trying with children?
Abbie- they had SOOOOOOOOOOOO much fun! We go through vinegar and baking soda by the case around here
Ticia- What a great idea with the toilet paper! I bet that would work great too! Our dinosaurs are never far away from anything we do. The children love to incorporate them in any way that they can!
There has been a lot of buzz about light tables over at Teach Preschool on Facebook . Deborah has collected some great ideas for light table play and has been experimenting with making her own table over on the Teach Preschool blog. I thought I would share with you our two light tables and how we made them. This first table is one that we put together with some scrap wood pieces, an old plexi-glass door from an entertainment center, and a couple of aquarium lights. Total Cost = $0. (We had everything on hand.) The table needs a little bit of tweaking. (It is on my to do list). Basically, we made a frame of wood around the plexi-glass and placed the lights under it. Our DIY skills in putting this together were far from expert, so the frame has a couple of gaps (and the reused wood is warped). We plan to try a new frame and use some caulk to seal any gaps. We also plan to attach the lights to the side of the frame instead of just placing them on the f...
Yesterday, I hope I convinced you not to throw away your markers that "don't work." Today, I will share with you a few ideas for what to do with all of the caps. The possibilities are nearly endless, but here are a few of our recent creations: 1) A Leprechaun/Fairy Ladder/Rope Ladder: 2) #1 if not permanently secured can also double as a rope bridge: 3) #1/#2 can also be made into a train track for your homemade trains :). (No photo available) 4) You can use them as beads for a necklace: 5) You could make them into a wind chime. (No photo available). 6. You can use them as small manipulatives to count, sort, and make patterns with. (No photo available). 7) You could use them as playing pieces in your own homemade board game. (No photo available). 8) You could put them on a wire and glue them in place to make a twirling whirly-gig. 9) You could top them with a lid from a milk jug to make tiny tables or toadstools. 10) You could make them...
How may times have you heard, "Ms. (fill your name in here), this marker doesn't work!" I know I hear it all the time. Sometimes it is because our little friends forget to replace the caps, and sometimes the markers have just been "all used up!" What do you do with all those markers that just don't work? Please don't tell me that you throw them out, try this instead: First, sort your markers out. Put the caps in one container ( save those too, I'll show you what you can do with them in tomorrow's post) and the markers in another. I have a box for the markers that "don't work" for the children to place them into every time they run across one. You can also have the children help you test the markers periodically to sort out the ones that need to be removed from the "working set." When it comes time to use "the markers that don't work," we use a small sponge paint roller to roll water onto our card...

When we did blow the cork off we wrapped the baking soda in a small thing of toilet paper.
Ticia- What a great idea with the toilet paper! I bet that would work great too! Our dinosaurs are never far away from anything we do. The children love to incorporate them in any way that they can!
