From the Science Department

Teachers are helpers and everyone wants to help you right now. Our science department head has put together some weekly science ideas. Next week's ideas revolve around sound!

Sound Travels

Science Enrichment  K-2

April 6th - April 10th

Monday April 6th

Watch this brainpop jr. video to learn about sound and how sound travels from one place to another.

After watching the video try this: 

-Put your hand in the middle of your throat. Say the word “ahhhhhhhhh”. 

-Say “ahhhhhhhhh” in a higher pitch

-Say “ahhhhhhhhh” in a lower pitch

-What do you feel with your hand? What pattern do you notice?

-Tell your teacher what you observed. Can you explain why it felt this way?

Tuesday April 7th

Sound needs something to travel through in order to reach your ear. 

Let’s experiment with sound travelling through string.

Watch this video with instructions to get started.

You will need sting and different objects to test.

Here are written instructions

Test different objects - a hanger, a big spoon, a little spoon, a wooden spoon,
whatever you are curious about.

Share with your class which object made the most pleasing sound in your ear. 

Wednesday April 8th

Sound travels through different materials differently. 

Let’s experiment with sound travelling through other things besides string.

Watch this video about sounds travelling through solids.

Try it for yourself! 

-Put your ear on one end of a table. Have someone knock at the other end. 
Is the noise louder than when it travels through the air?

-Try it again but this time use a different material. What happens when you put
your ear on a chair and knock? Try a book, a glass, a broom handle.  

-Share your results with your class.  Which material made the noise the loudest?

Thursday April 9th

Usually the sounds we hear travel through the air. 

Watch the first 3 minutes of this video.

-Can you think of an experiment that could help you find  out if there are vibrations
in the air when we talk to each other. Tell your teacher what you came up with. 

-Close your eyes.  Have someone else make a sound - tear paper, zip a zipper,
clang a spoon, open a book, etc. With your eyes closed can you guess what the noise is? 
Was there any noise you could not figure out?

Friday April 10th

Sometimes we can direct sound so that it goes where we want it to. 

-Cup your hands behind your ears. 

-Face your partner and have them whisper to you

-Then listen without your hands behind your ear. What do you notice?

Grumpy Monkey

Hello friends!

We have all been feeling lots of feelings while at home!  Below I am reading the story Grumpy Monkey by Suzanne Lang.  At the end, I ask the kids to draw and write for me.  Email me a picture of their work.   I can't wait to see what they do!

Segmenting and Blending

There are lots of things we do at school everyday to help promote phonemic awareness.  Understanding sounds and how they combine into words or how words break down into sounds helps with both reading and writing.

Segmenting:
We do a LOT of work on this skill.  Segmenting is how many sounds a word has, not how many letters.  For example, the word oak segmented would be "o-k" and the word house would be "h-o-s" since those are the sounds you heard.  Click here for a set of Elkonian box words like we use in school.  It is okay if you do not have a printer, you can view the pictures on the screen and have your child touch each box as they segment the word.

Blending:
Blending sounds back together is trickier than it might seem!  You can play a "guess my word" game with your child.  You can say the sounds of simple words, like "c-a-t" and have them blend and say the word "cat"

Here is a good youtube video about how you can model and help your child tap out and segment simple words.  

Friday Flash: Colors

Share the News:
Each morning we “share the news” with a buddy. Here is a question for each day of the week! Monday: What is your favorite color?
Tuesday: What’s your favorite red fruit?
Wednesday: What’s your favorite green vegetable?
Thursday: Have you ever seen a rainbow?
Friday: What is something you’re grateful to have right now?
Check Twitter each day next week for my responses!

At times for sentence practice I have the kids write a joke. They make a line for each word and then write all of the sounds they can hear. I save the answer for when they’re done. Here are a few ideas: What’s a cat's favorite color? Purrr-ple
What color is a ghost? BOO
Where do crayons go on vacation? Color-ado

Mix up some color for a bird art project 

Write your sight words in rainbow colors using this paper. 

Try a color science experiment: walking rainbow! 

Head into your yard and find something that is each color.

Handwriting

At school we practice handwriting using the "Zaner Blouser" style of writing. I was sending home the strands as we finished them. Click here for a document with the language for each letter. I have started to make digital lessons of me teaching handwriting lessons. When we practice at school the students watch and listen to me, then practice on their own (at times with music.) I have made these lessons to replicate what we do at school! I hope to be able to do all the letters in the coming week. If your child is writing their name at home, they should be writing with lower case letters (except the first!) and we had recently started practicing our last names as well.

 Here are two lessons for the "magic c" letters c o and a and the second for c, g and d.

Work it!

The Tools of the Mind program that Arlington adopted has a large focus on the working memory.  According to some research, the working memory at age 5 is a better indicator of academic success at age 11 than IQ.  Working memory helps one to plan ahead, problem solve, organize and pay attention.

So what does all that serious jargon look like in the kindergarten classroom?

Freeze Dance!  Every day we have been dancing to the freeze dance.  I hold up a pose that the children must replicate at the freeze.  Recently I have given the freeze dance another step.  The poses are posted on a color.  Instead of holding up a pose, I hold up a color.

Working memory helps us stay involved in something longer and keep more things in mind while approaching a task.  In this case, they're keeping the pose in mind while also keeping what each color means.   The children use their working memory to keep the goal (the pose) in mind, resist distractions and inhibit impulsive.

We also talk aloud a lot to help plan our learning.  Ever try to remember a grocery list or a phone number by repeating it aloud?  That is a strategy to assist your working memory.  As we learn the formation for letters and numbers, the children say them aloud.  Here are the formations for 5-9.


Before the children write, they say their idea to a buddy.  During the writing process, they have multiple opportunities to say their message aloud while writing.  This helps them to remember what they were intending to write.

We also play a game called Look and Remember.  I show a picture (related to The Magic Tree House we're reading) and the children talk to a buddy about all that they see.

Then I flip over the picture and ask questions like, "What letter is on the flag?  How many palm trees are there?"  The children answer my questions to their buddy.  Then I flip over and we go through the questions together.  This is explicit practice to help their visual and auditory memory skills!

Tools of the Classroom

The last few years, Arlington has adopted a program called Tools of the Mind.  In short, to really function as a learner children need to learn more than a set of facts and skills. They need to master a set of mental skills: the tools of the mind!

Many people can cook: they can throw pasta in a pot and heat up a jar of Ragu.

But a chef!  They are usually known for their great skill.  People don't tune into shows like Chopped and Iron Chef to watch someone open up a cook book and read a recipe!  These are skilled people who know how to put ingredients together into a delicious meal.

The Tools of the Mind program is based on Vygotsky.  He felt until children learn to use mental tools, their learning is largely controlled by the teacher.  But if they are able to master mental tools, they can become in charge of their own learning by attending and remembering in a purposeful way.

And when you have 5 minutes, here is a great video on Executive Functioning, featuring one of the creators of the Tools of the Mind program.
