Week 23- Valentine's Day

In chemistry this week we have been learning about acids and bases. Of course, I have a song for that. So here is the song we sang all week!






We used iodine and BTB to test the powders we have been using in our chemistry unit.












Iodine is a starch indicator and turns black if starch is present in the powder.



BTB (Bromthymol Blue) is a pH indicator. The powder turns blue if it is a base and yellow if it is an acid.



Today we mixed up our mystery powders and the kids will use their notes next week to try to determine the two powders that were mixed together.

Fifth grade teachers went to a math workshop this week and we talked about using beans and pasta to make fraction plates. So Mrs. Reasner came up with the idea of using Valentine's candy to create plates of fractions.



In math small groups, the kids selected up to 20 pieces of candy to glue to their plates.



Then they had to write a fraction for each kind of candy they had on their plates. I challenged them to write the fractions in simplest form so it wouldn't be as easy to find their plate later. Here are just a couple of the plates that were created.





I found this Criminal Cupid activity on Teachers Pay Teachers. My kids loved it! I read the story to them and they each took notes about how the criminal looked. Then they were the sketch artist and had to create a picture of the criminal.



I also asked them to write a short paragraph about what happened. I let them decide if they would tell the story from the point of view of the criminal, the witness, or Cupid.





STUDENTS: We have a lot of songs that we sing in class to help you learn things. What is your favorite song so far? It can't be a brain break song, it must be a song that we have used to learn something in the classroom. Don't forget to use a 7 up sentence for a bonus ticket. Sentences start with a capital letter and end with some type of punctuation.
