Science Sunday- Sinkers



We took a break from our nature study to do a fun experiment. I collected a variety of items from around the house to see which ones would sink or float.

First I had Froggy go through the items and sort them based on her guess as to which would sink and float.
Then we tested each item one by one and placed it in the appropriate location. We got a few surprises. Two of her figurines floated. We even went back and got more figures to see if we could determine a difference between the floaters and the sinkers. We could not. There was no distinguishable difference. Ones for the exact same collection were in both categories. It was not quite the experiment I had hoped for.
Still we persevered. We looked at why the balled bread sunk while the slice floated. We talked about density.
After the experiment we continued the study with some fun reading. We pulled back out one of our favorite series Magic School Bus, Ups and Downs: A Book about Floating and Sinking. and a Rookie Reader What is Density?

I'm linking this post in with the Science Sunday link-up, at Adventures in Mommydom, where you can find more fun with science.

    I like how you link your experiments with books you read. Too funny about figurines, it could have something to do with their overall shape.

    I'm with Raising a Happy Child - I think it might be the shape of the figures, causing them to float. Interesting.

    I'll echo the other two, shape. Or maybe one is hollow.

WFMW - Sewing Machine

Image
What works for me this week is my sewing machine. I am in love with my sewing machine. I have missed it. I have been so busy with my classwork that I have not pulled it out since I finished Froggy's Halloween costume. This week has been a return to normalacy and for me normalcy means sewing. I finished finding m y c raft room on Monday. So yesterday I sewed. I made a skirt for me testing out a new pattern. The pattern is basic and easy with very little fitting. It is not the most flattering of patterns but it supposed to be a plain backdrop for embellishments. I may add a bit of shaping so it is not so full through the hips when I make it again with the embellishments. As soon as the weather dries out, I can go outside and spread out and sandwich together the baby quilts I need to finish up for the new arrivals that are almost here. Come see what works for others at Rocks In My Dryer

Tadpoles II

Image
Our tadpoles are still alive despite some very dubious care.  We went to check on them and found that one had sprouted teeny tiny legs.  It was amazing how tiny the legs were, so tiny that at first I thought it was a smudge of dirt clinging to him. Froggy suggested we document the moment in our journals.  So we did.  It was lots of fun watching Froggy making multicolored tadpoles. Continuing our Frog theme, we completed a fun worksheet from Adventures in Mamaland about the life cycle of the Frog.  Froggy was thrilled with the opportunity to learn the Hebrew names for her current passion.  To tie everything together we made Froggy's pride and joy - a poster of the life cycle.   I drew the shapes which Froggy cut out.   Then she pasted them next to the appropriate label I had written.  Then she decorated them.  Complete with googly eyes because "googly eyes make everything better."
