Today we looked at the relationship between a concentrated solution and its density. Students investigated 4 mystery solutions to determine their densities and rank them in order. To do so, they tried layering the liquids in a straw so that the lightest (least dense) liquid was on top and the heaviest (most dense) was on the bottom. Students were surely engaged! Now, they know that if a balance or scale isn't around, they can use density to find the level of concentration of a solution.
We had our annual Digit of Pi Memorization Contest today, a few days before Pi Day (March 14th is over Spring Break this year). It is amazing how many digits students can memorize in just one week. First place went to Carys, who memorized and sang the first hundred digits of pi and then recited another 17. Yes, she memorized 117 digits of the number. Second place was Chayse with 98 digits. I'm so proud of all the students in the class, as each and every one of them know more digits of pi than most people, as math classes usually only focus on the first 3! Even fifth place memorized 83 digits of the infinite number.
With Pi Day (March 14th.....3.14) over spring break, we celebrated the idea today in class. Working backward, students measured a variety of round pies to find circumference. Next, they measured as accurately as they could the diameter. Finally, the divided circumference by diameter to realize that 3 is almost always found. After explaining that this means the circumference is about 3 times that of the diameter, we put all the data in Excel and found that our class average of all the groups' measurements was 3.12. Not bad for measuring pies that are not 100% round.
We have slowly started to transition into space science, while also still working on physical science. Over the past month and a half, we have measured the length of our shadows at 9:10 am every Tuesday. This week, we will analyze our data of how the shadows have been getting shorter each week. After understanding the movement of the sun and earth in relation to the shortening of the shadow, we will attempt to find patterns in our data to predict the length of our shadows after Spring Break.
We finished up Reading Week with a bang! Thursday was Dr. Seuss day and we had over half the class dressed up in all sorts of craziness. Friday was Pajama Day. There sure were lots of fancy PJs.
Today was western day, and many showed up ready to ride! The excitement of Reading Week continues.
For reading week, the school has offered some fun dress up days. Today was "Tacky Tourist Day". Our class surely fit in with that!
