The new school year has started!! Last week went off without a hitch and the girls are settling in nicely to the schedule of things. The new schedule is every day from 8:30 to 1:00. I've got 3 different grade levels in the classroom, so I try to do as much cross grade level curriculum as possible. We've been learning about the Nature of Science (TEKS: 3.1-3.4; 7.1-7.4, 8.1-8.4), which is technically the same across the board for all three levels. So today we tested the waters in our scientific reasoning! {Taylor was actually doing 8th grade material by the end of it, so I was pretty impressed!} Last week we covered the lab safety rules {TEKS: 3.1, 7.1, 8.1} ...... boring. So I thought they deserved something fun!
I mixed 3 different bubble solutions {A, B, C}. There was 1/2 cup of bubble's in all three {constant variable!}. Cup A was the control, Cup B had 1/2 cup of water, and Cup C had 1 cup of water. The goal was to determine which solution would produce the largest bubble. So we measured the diameter of the popped bubble on our desks!
They came up with their hypothesis's, and the fun began!

| I love Josie! She is such a dedicated scientist! She took this experiment very seriously. |

| Wait! Is Josie goofing off?! |
So as you can see, we thoroughly enjoyed ourselves in science today. The only one whose hypothesis was proven in the end was Taylor! She stated that "Solution B will make the biggest bubbles because it does not have too much water and not too little water." I personally thought that solution A would make the biggest bubbles, but apparently my hypothesis was not supported!!
We recorded our data on a bar graph to show the class averages. We did multiple trials on each solution to get the most accurate results possible!
I was super proud of the girls today! Although they had plenty of fun with their bubble experiment, they had an hour and a half {sheesh!} lesson beforehand.

And as I sit typing this, I have Taylor sitting at her desk {during her lunch mind you} doing her homework for tonight. I've got some hard workers in this room!!
Until Next Time,
