Today’s experiments (8 & 9) both investigated surfacetension. In this milk experiment, we watched as dish washingsoap broke the surface tension of the milk and sent dyeracing away. So, here’s what we did:1) Pour a small pitcher of milk onto a plate2) Place 1 drop of each color — red, yellow, blue and green3) Dip a Q-tip into dish washing soap 4) Place the Q-tip gently in the center of...
Now you can continue altering the surface tension, dippingthe dish-soap covered Q-tip in various spots in the milk.
We had some really interesting movement when weadded a drop of blue and red food coloring and then leta couple drops of soap drip into the milk. The kids really, really enjoyed this experiment! I highlyrecommend this one. I’ve seen this experiment in a number of places, but there’sa good explanation of the science behind it all at:http://www.abc.net.au/science/surfingscientist/pdf/lesson_1_amazing_science.pdfon pages 6-7.
Grandpa sent us a wonderful science video clipabout water drops. So, I set up this experiment togo along with the two minute video (which wewatched afterward). The experiment wasquite simple, but the kids were at it for at leasttwenty minutes! 1) Pour a pitcher of water into a dish2) Place some colored water into a small dish3) Using an eye dropper, pick up some coloredwater.4) Drop ONE drop into the...
This week I’ve been putting a letter sorting activity in DD’s workbox. I chose a small toy/item, wrote that word on a piece of paper and had the first letter of that word (in lower and upper case letters) that she had to sort into rows. She’s also been finding the letters to make words and has been quite motivated to do that. Other related posts you might be interested...
I wasn’t quite sure what to call this post, buthere’s an activity we did today. Part I: I put letters on some cards and hid them aroundthe yard. DD (4) had to find the animal worker lettercards. LD (6) had to find the stars.
Part II: DD had to sort her hard hat animals into different colors.Then she had to put the letters in the right order tomake the words house, flower and teddy bear. LD had to take his letters, make as many words as hecould and write them in his notebook (men, cent, pin etc). He’s been unhappy about his journal writing, but hereally enjoyed this activity.
Here are some quick online games LD has played to review his math facts the past few days (some are pretty easy, but some such as ghostblasters, you can work on any sum up to 50).

Sorting/tonging for EDKanoodle (a brain teaser) for LD – a big hit, thanks Auntie CStamping for DD (upper/lower case letters)
LD also built his robotic bird. He loved it (thanks forthis too Auntie C!)
Here’s our craft table all set up with a science station. Theseexperiments have to do mostly with magnetic attraction,although we have one on particle attraction as well. I also have the magnetic maze (a gift from a formerkindergarten teacher/friend) and a craft on the milky waygalaxy.
This is a simple lesson that shows how particles areattracted to each other. Just have them drop paper intostill water (don’t blow or move the water around) andwatch the bits of paper move toward one another. We used bits of paper from my comb binder, but anysmall pieces should work. I’ve heard that you could alsosubstitute talcum powder or baby powder, but we did nottry this.
LD and DD just played around with a magnetic set we’vehad for years. They also tried an experiment to see if heat or cold affectedthe magnet’s force. (education.com)
