Here is another voicethread about the Native Americans of this area. Alison and Maggie did a great job learning about how the Pequot, Niantic, and Narragansett tribes made clothing from animal hides.
This voicethread was written and recorded by Alison with technical support from Emmett.
To get an idea of what it was like to sew clothing out of tanned leather, Alison, Maggie and Alexandrastitched together a Native American style pouch.
Sewing a buckskin pouch
Here is the finished product, decorated with markers instead of dyes from berries:
Of course, the native Americans would have had to skin the animal, tan the hide, cut the leather, poke holes for the bone needle, and make dyes from plants and berries – all without the help of any metal tools!
What was something interesting you learned?
Do you think it would be hard to make clothing the way the local tribes did?
Is there anything else you would like to know about the topic?
We have one more round to go until the final four next week. This week’s poems are read by; Tyler (The Sloth), Sean, Autumn, Erik, Gus, Emmett, Jacob and Sam C. (Seal), Sam L. (Weather), and Sam K. (Smart).
Here are this week’s poems. Which one will join Monster Mothers, Jabberwocky, and I’m Disgusted With My Brother in the final four? You decide! Have a listen and then vote for your choice.
We have been working on reading with fluency.
Mrs. Yollis’ class has been a BIG help with their excellent audio posts of poems. In fact, we liked their readings of Seal by Jay William Smith and Smart by Shel Silverstein so much that we included our versions of those poems into this week’s competition. Please take a moment to listen to their amazing versions!
Which poem did you choose? Why?
Which poem do you want to win the whole tournament?
The salt made the water thicker so it pushed the egg up.
The salt made the water heavier than the egg.
The egg was heavier than tap water but lighter than salt water.
Than someone wrote a comment about density. Hmm, what is density?
Well, everything that takes up space is matter and all matter has weight. Matter that is the same size can weigh different amounts because of how tightly packed the molecules are. This is density. Matter that is heavy for its size is very dense because the molecules are tightly packed. Dense objects are also hard. Matter that is light for its size is less dense because the molecules are not tightly packed. Less dense objects are soft or easy to move aside.
Here is a diagram showing the density of the three phases of matter – gas, liquid, and solid:
You can see that liquids are less dense than solids. That is why we can push our hands through water – the molecules move around our hands into the extra space. It is super easy to push your hands through air because there is so much space for the molecules to move into.
Pushing your hands through solids, like your desk, well… That’s a little harder! There is no space for the molecules to move to.
So, what about buoyancy?
Objects sink or float depending on their density. If they are less dense than the water, they will float. If they are more dense than the water, they will sink. So, an egg is less dense than salt water.
Different liquids have different densities. Salt water is denser than tap water, but that is just the beginning. Check out this experiment we did with different liquids floating on each other!
Science is AMAZING!
What is the most interesting thing you learned about density and buoyancy?
Why do you think helium balloons rise and regular balloons fall?
Do you have any questions about density or buoyancy?
After our boat building activity, we were really wondering about what makes some things sink and others float…
At first many of us thought that it was just weight; heavy things would sink and light things would float. So we tested that out with a marble and a ball of wood.
Weighing a ball of wood and a marble
The wood was heavier. So, it would sink and the marble would float right?
Hmm… The wood floated and the marble sank even though the wood was heavier than the marble.
So sinking and floating couldn’t just be about weight. Maybe it had something to do with the water. We decided to do an experiment to see if we could make an egg float.
Can an egg float?
We started with an egg in regular tap water (it sank) and added one teaspoon of salt to the water and stirred it in good until it dissolved. We kept adding one teaspoon at a time to see if we could get the egg to float.
Here is what happened:
Every group got their egg to float, but some needed more salt than others. Some groups got their eggs to float with only 4 teaspoons of salt, and others needed 7, 8, and even 9 teaspoons of salt!
Why did the egg float in salt water but not tap water?
Why do you think different groups needed different amounts of salt to make the egg float?
Our new science unit is all about Properties of Matter. Properties of matter are the ways that we can describe matter. Some physical properties of matter are: weight, texture, color, absorbency, transparency, and many others.
We did a science activity to investigate the property of Buoyancy: if an object sinks or floats.
Buoyancy – Sink or Float
Mr. Salsich gave partners a limited amount of materials to try to build a boat that could float and also hold marbles. We tried to see how many marbles our boats could hold without sinking. Here are the materials we were given:
4 rubber bands, 4 straws, 6 Popsicle sticks, a stick of clay, and a 6 x 12 inch sheet of tin foil
We didn’t have to use all the supplies, but these were the only materials we could use.
Here is a video showing what we did and what we learned.
(Special thanks to Tommy’s mom for helping test the boats!)
Have you ever done a “sink or float” experiment?
How do scientists learn?
Some students said the tin foil floated because it was light. How do heavy, steel ships float?
I started to play the piano when I was six. Before I took lessons, I taught myself how to play scales and other things. My older sister, who already took piano lessons, helped me learn the notes and key signatures.
notes for treble clef and bass clef
I have been playing for two years. I know a lot of songs and a few scales.
A piano is an extremely interesting instrument. It is a string instrument. The piano has short strings for the high notes and long strings for low notes. It has soft “hammers” to bump the strings and the strings vibrate to make a noise. You can play loud and soft by hitting the key harder or softer.

I think that the piano is a fun instrument to play, but you need lots of practice. I play after school. After I’m done practicing I like to fool around and make up my own songs.
Here is a video of two songs that I can play; The Pink Panther Theme by Henry Mancini and Musette by J.S. Bach.
