Wondering About Sound on Wednesday and Thinking Riddles on Thursday

By Anonymous -
We have been expanding our identity definition by trying on our scientist hats this week.  Wondering Wednesday began with a question:  I wonder how a car horn works?  You used your background knowledge and the new knowledge we have been gathering to make some really clever inferences about the answer to this question.  I was very impressed how you communicated your thinking about this and how you recycled the science vocabulary accurately as evidence to back up your inferences. Here is some of the vocabulary we have learned.  We made some interesting inferences about how nature has inspired our understanding about sound waves.
The video sparks even more questions about sound and biomimicry.

Tell your parents about why sound travels at different speeds through different mediums such as air, water and rock.

We are really beginning to understand how the ear works and that hearing is transferred into electrical currents that are sent to the brain.   Here is a diagram of the ear:



You were really excited to use the tuning forks to investigate how sound travels through different mediums.  We got to practice our math skills by collecting data in a chart and then analyze the data to ask more questions and make inferences about how sound travels and the frequency of sound waves. 



Riddle me this,  riddle me that ... what makes a good riddle?  We found out when we began writing our Halloween riddles today.  Here are some of the criteria we came up with after we shared and gave each other feedback.  
Our inspiration for these riddles was this book:  


Here are some of our riddles:  
When someone looks at my eye 
I turn them into stone
I have snakes as my hair
What am I?  

I have a scarred, green face
I live in a haunted place
I wear a black suit
What am I?

I'm very gloomy black
I have eight legs
What am I? 

I am as green as a goblin
I'd love some soup
I have a pet cat
What am I?   

I am a thing that people eat
I look like corn
I am so sweet
What am I?

Math on Fantastic Friday

We have been working on number of the day this week.  It is a great strategy for expanding our understanding of number sense.  Here is an example of what it can look like.  It gives students a way to practice multiple ways to work with a particular number.  A new number is picked everyday.   You can practice this at home with your parents.  Another category to add to this when you talk at home about numbers is:  Where in the world would  I find this number of things?      For example I might find 615 students in a middle school.  Or 615 dollars in my bank account.  Or 615 paintings in a gallery or 615 cattle on a ranch.   We have also been challenging ourselves to understand how  fractions and division are connected .  Below is a picture of how we can divide the number 368 in half.  Or, another way to look at is 368 divided by 2:  You can see that we have modeled how to divide this numbe...

Welcome to our new student in Room 123, his name is Toluwani and we are very happy to have him join our community.   If we attached an EEG (stands for Electroencephalography and measures the activity of neurons in the brain) to your brains in Room 123 today your firing neurons would light up the community of Evanston. You were on fire with the thinking today! Global Mind in action. As per usual, we went on a learning journey beginning with the Metis people, identity through meeting (via video) David Bouchard.  He is an amazing inspirational Metis author who happens to have written more than 50 books in English and French. Many of these books combine poetry and visuals to explore topics like the environment, history and traditions and cultures of Canada's Aboriginal communities.  Here is are some video links for you to meet him too:   https://www.youtube.com/watch?v=20tEPCJWj20 https://www.youtube.com/watch?v=BdPtMZbgEBY We learned that the infinity sy...
