Homeschool Science Fair

Today we participated in our local homeschool group’s Second Annual Science Fair.

The fair began with the hostess, A, having all the kids make ice cream in a bag. They used rock salt and ice in a gallon-sized baggie with a smaller bag inside holding the ice cream mix. Then they got to enjoy their ice cream while the presenters went up in front of the group.

S10 did a project on crystal formations using a Borax supersolution.  Borax is dissolved in boiling water, which will dissolve a greater quantity of borax than warm or cool water will.  As the solution cools, the excess borax precipitates out and you can collect it on a pipe cleaner form.  These are the same “crystal kits” that she sold at the Kid’s Marketplace a few weeks ago.

O8 did a slightly more intensive project.  She wanted to know how fast her arrows go when they are shot from her bow.  We enlisted the help of my BIL, who has access to a high-speed test camera through work.  He did some films of her arrow shots and then helped her calculate its speed using the camera’s software.

After the fair, we went to gymnastics and then S10 attended the gym’s practice for Sunday’s Intra Class Competition.

Gymnastics Competition

Today S9 competed in our gym’s annual “Intra Class Competition”. This is a fun, low-key meet at the gym and gives the recreational classes a chance to see what a real meet is like.

S9 competed in all the events: Rope Climb, Vault, Floor, Beam, Bars, and Trampoline. She placed in each event, taking second in the rope climb and 3rd or 4th in the remaining events.

Gymnastics Camp

Today the kids spent the day at their gym, which was offering a Waiver Day Camp.  Most schools in the area were closed today as part of the President’s Day weekend.

They got to do a few hours of open gym, plus some craft time and games with about a dozen other kids.  Their craft was really cute: the coach snapped a photo of them out in the gym, printed it out, and they made an embellished foam frame for it.
