Explosion of vinegar and baking soda

 

What will happen if we put vinegar and baking soda in a sandwich bag?

We put vinegar in a sandwich bag and added baking soda, and the zipped sandwich bag popped!

Mixing vinegar and baking soda causes the sodium bicarbonate (baking soda) to react with acetic acid (vinegar) releasing carbon dioxide gas and making sodium acetate. The CO2 gas production caused the ziploc bag to pop.

 

 

Fire Resistant Water Balloon

 

 

What will happen if we put a flame under a balloon? What will happen if we put a flame under a balloon filled with water compared with putting a flame under a balloon with no water?  The balloon without water popped when a flame was placed under it. The balloon with water in it did not pop when a flame was placed under it.

The thin balloon allows the heat to pass through very quickly and warm the water. As the water closest to the flame heats up, it begins to rise and cooler water replaces it at the bottom of the balloon. This cooler water then soaks up more heat and the process repeats itself. In fact, the exchange of water happens so often that it keeps the balloon from ever popping! The carbon was deposited on the balloon by the flame, and the balloon remains undamaged.

 

Paper Towels vs. Diapers

-Absorption  “ To take something in”

 

 

What will happen if we pour water in a container containing paper towels and another container containing Sodium Polyacrylate(the stuff in diapers)? Which will hold  more water, paper towels or Sodium Polyacrylate?

The container with the paper towels absorbed some water but not all the water. Some of the water spilled out of the container. The container that had Sodium Polyacrylate absorbed all the water. None of the water spilled out of the container.

The Sodium Polyacrylate holds more water than paper towels and is therefore, more absorbent.

 

Magic Milk Rainbow

Surface Tension

“A property of a liquid keeping an object from going into the liquid”

 

What will happen if we put drops of food coloring on the top of milk in a bowl and place  dish soap in the middle of the milk?

We placed the drops of food coloring(green, red, and yellow) on top of milk in a bowl and we put  dish soap on the end of a Q-tip in the middle of the milk.

When we dipped the dish soap soaked Q-tip in the milk the food coloring swirled!

Food coloring is less dense than milk so it floats on the surface of the milk. When the dish soap touches the milk, the milk’s surface tension changes and the milk begins to move in an attempt to keep normal surface tension. This movement causes the food coloring to mix creating a milk rainbow.

 

Pop Rock Expander

-Chemical Reaction

 What happens when we mix Pop Rock candy and soda? Should we ask Mikey?

 

First, get an entire package of Pop Rocks into a balloon using a funnel and place the balloon over the mouth of a bottle of soda. Grab the balloon and dump the Pop Rocks into the soda. And then the balloon was inflating!

Both candy and soda contain pressurized carbon dioxide gas. When the Pop Rocks are dropped into the soda, aome carbon dioxide is able to escape from the high fructose corn syrup of the soda and, because the carbon dioxide gas has nowhere to go in the bottle, it rises into the balloon.

 

 

Dancing Spaghetti

-Carbonation

What are the bubbles? What will happen when we put cooked spaghetti in a fresh glass of baking soda/vinegar mixture?

We made a “batch” of baking soda/vinegar mixture(2 cups of  water and 2 cups of vinegar). We dropped several strands of cooked spaghetti into the baking soda/vinegar mixture, Add 1 tablespoon of baking soda to the water/vinegar mixture.

The spaghetti sinks to the bottom of the baking soda/vinegar mixture. Then when the baking soda is added bubbles are produced lifting the spaghetti throughout the liquid.

The carbonated bubbles rise to the top “pushing” the spaghetti towards the top of the bowl creating dancing spaghetti,

 

 

Tea Bag Hot air Balloon

What will happen when we set fire to an unused, empty tea bag?

 

First we cut the unused tea bag and discarded the tea leaves and then made the tea bag into a shape of a cylinder. Mr, John set fire to the tea bag, As the tea bag burned, it began to float up.

When the tea bag burns down it gets lighter in weight and the air around the flame gets hotter. Hot air rises and once the burnt tea bag is light enough it gets carried up with the hot air.

 

 

Suspension(chemistry)

-A state of matter “A fluid containing solid particles”

What will happen if we mix cornstarch and water?

We mixed cornstarch and water and slowly put our finger in the mixture. We quickly hit the mixture.

 When we slowly put our finger in the mixture it went into the mix like a liquid. When we quickly hit the mixture our fingers stayed dry, out of the mix. It felt like a solid.

 By mixing the cornstarch and water we created a state of matter known as suspension. When we hit the Cornstarch Suspension it felt like a solid because its molecules line up. But it looks like a liquid and acts like a liquid when no one is pressing on it because the molecules relax.

 


A Peek Into Art Class | May 2018

With Ms. Renee

Week of May1st
This week we talked about what a portrait and a self portrait means in art. Each of the students drew a picture of themselves using crayons and colored pencils and then we made a “silly” self portrait similar to Pablo Picasso famous cubist art! The students loved talking about their silly portraits and what crazy things they were adding to their faces!
 
Week of May 7th
The students enjoyed making clay pots a few weeks ago so we got out the clay and created some goofy monsters! Watching them use their imaginations to create something only they could envision was so much fun. Each one was truly unique!
 
Week of May 14th
This week we talked again about self portraits and how we could make a portrait more “life-like”. Using construction paper, the students created 3D portraits that resembled themselves. They really enjoyed finding ways to create hair that stuck out from the paper!
 
Week of May 21st
For our final art class in Tallmadge I created art stations that involved some of the students’ favorite mediums. We had a really fun sculpture station, a chalk and oil pastel station and a watercolor/paint stamping station. Giving the students time at each one to explore and create was the perfect way to end the school year!

Eggs in different liquids:  We decided to do an experiment by placing eggs in different liquids to see how the different liquids would affect the egg shells. We chose to place an egg in water, milk and vinegar. The water and milk had caused the eggs to gain weight. The vinegar caused the egg not only to gain weight but striped off a layer of the eggshell making the egg squishy.

Parachute: We created two parachute’s one out of paper and one out of plastic. Then, we dropped both parachute’s to see what would happen. When we dropped the parachutes the strings that were attached to the plastic and paper pulled down, which in turn made the parachute’s open to full size. When the parachute’s opened to full size it created a large surface area and more wind resistance. The more wind resistance there was the slower the parachute’s went down.


A Peek Into Music | February

February was so much fun in Miss Lisa’s class! We reviewed Peter and the Wolf, started learning about the piano, practiced our listening skills and played some fantastic games! Check out our fun pictures below to see more details of these fun lessons!

Here Miss Lisa is introducing the piano. It is so neat that she can bring in her piano synthesizer to us! She teacher us about the difference between the white and black keys to start with.
Here we are reviewing our February story Peter and the Wolf. We learned the named of many new instruments last month and the sounds they make!
Here are two friends exploring the piano synthesizer. This week we were exploring the black keys only. In pairs, we played our own creative duet for our class. We practiced taking a big bow after our duet!
One of our favorite games we play is cat and mouse! This game helps reinforce our listening skills. The mice have to get the cheese while the high music is playing, with the best audio systems from https://holoplot.com/software/. When the low music starts, the cats come home and the mice hurry back to their hole!
One of the great features of the piano synthesizer is that it can play all sorts of sounds! We had a blast playing a guessing game. Miss Lisa played us sounds of different types of transportation, people noises and animals this month. We had a great time guessing! This game also helps us practice patience, which at our ages isn’t always easy!

 

We can’t wait to see what fun activities Miss Lisa has planned for us next month!


A Peek Into Art – February

We had a fun month together in Art Class!  We continued our travels back in time, all the way to Ancient Greece! We learned about the Ancient Greeks and how they told their stories through art on vases. We talked about how important story-telling is in art and how the ancient artists displayed their artworks all around them (on ceilings, floors, walls and their every day objects). We learned about the different styles of Greek vases and what the parts of the vases were called. Then we made Greek vases and told our very own stories, about our families, on them using colored pencils. It was really special to see each student draw their families and pets on their vases!
In celebration of Valentines Day this week, we used our liquid watercolors and q-tips to practice the art of Pointillism. The students very carefully traced hearts and then carefully added dots of color along the edges and inside of the hearts. Watching the students focus on this art project was wonderful, as they worked on placing their dots on the lines.
In Art this month we also learned about Eric Carle’s Draw Me a Star and talked about the color and methods this author, illustrator and artist uses in his work. Then we got to work making our very own star, similar to the one in the story! Each student was given a pre-drawn start and asked to carefully cut and glue squares of tissue paper onto it. After they finished, each student cut out his or her star and glued it onto a blue “sky” background. For the finishing touch, we added fingerprints of white paint on top of the tissue paper to recreate Eric Carle’s beautiful work! The students enjoyed cutting and pasting the tissue paper on to create a colorful collage!

Bouyancy – A force in a liquid pushing against an object in the liquid

In Science class we wanted to find out what would happen when we place peeled and unpeeled oranges into a tank of water. We hypothesized that the peeled orange will splash. Consequently we thought the unpeeled orange would make bubbles. First we peeled one orange. Next we left the peel on the second orange. Last, we dropped the oranges in the water. We observed the peeled orange sank while the unpeeled orange floated. We discovered that the orange peel traps air. So even though it is heavier, it is more buoyant. The peeled orange had no air, so it sinks.

 

Density- the mass in a specified volume

In a similar experiment, we wanted to see what will happen if we drop a lemon and a lime in the water. The lemon floated and the lime sank. We can concluded the lime is denser than the lemon.

A note from Mr. John:

I did some research for more information. According to the USDA website, a lime is 88.26% water by weight and a lemon is 87.4% which is a minimal difference. This could mean that lemons have higher air content, but I’m still researching why the lemon floats and the lime sinks.

Dancing Hearts: We put candy hearts in Sprite to see what would happen. The students had hypothesis like they will dissolve, float, sink and make a rainbow. We observed the carbon dioxide pick the candy hearts up and float on top of the Sprite. Then, when the hearts reached the top the bubbles burst and the candy dropped down again.

 

Upside down glass of water: We filled a glass up with water, placed a piece of cardboard over the top and turned it upside down. We discovered that the air pressure around the glass was greater than the weight of the water. Therefore, the air pushing up from underneath the water was strong enough to hold the piece of cardboard in place so the water would not spill out.

 


A Peek Into Music | January 2018

January was full of cold and snowy days but we stayed warm and active with Miss Lisa! We focused on rhythm and tempo this month. We used rhythm sticks and scarves to practice these skills.

Here students are using scarves to follow Miss Lisa dancing to the music. This lesson was focusing on the tempo of the music.

 

Here Miss Lisa is collecting rhythm sticks from students. The rhythm sticks help teach students about counting the beats and keeping a rhythm of the song. When they are collected Miss Lisa always encourages them to use their imagination to become an animal with the sticks.

 

A new unit we started at the beginning of January and finished at the end was “Peter and the Wolf”. We learned about the characters, the instruments and the story line of this classic tale.

Here Miss Lisa is introducing the instrument of Peter in “Peter and the Wolf”. Before listening to the entire story, students learn and identify which instruments indicate which character in the story.

 

Here the class is listening to “Peter and the Wolf”. Miss Lisa has illustrations to go along with the music of this tale.
Here is a great view of the wolf. Check with your student to see if they remember what character he goes after!

We had so much fun this month leaning about ” Peter and the Wolf”. The illustrations and music told such a vivid tale we will not forget anytime soon! We also learned about all sorts of instruments. Try listening to this with your student and see what they can identify at home.

Absorption – To take something in.

What will happen if we pour water in a container containing paper towels and another container containing Sodium Polyacrylate? What is Sodium Polyacrylate? It is the material in diapers. All the children shouted,  “Ewwww”~ for diapers.

Mr. John took the container with the Sodium Polyacrylate and water, and dumped it out above the children’s heads. No water spilled out! We had fun learning about absorption!

Leak Proof Baggy

Polymers – Polymers chains working together.

“What? You poked holes with a pencil in a baggy filled with water? It didn’t come out?”

Yes! We slowly, but firmly pushed sharpened pencils through one side of a zip-locked bag filled with water. The water doesn’t leak at all!

Why? Plastic bags are made out of Polymers which are long chains of individual molecules, called monomers. So poking the bag with water means separating polymer chains without breaking them.

SCIENCE ROCKS!

Play Dough Shapes

Buoyancy- A force in a liquid pushing against an object in the liquid.

We dropped different shaped (a bowl and a sphere) Play dough in water. The sphere shaped dough sank while the bowl shaped play dough floated. The sphere is dense and cannot push enough water out to stay a float. The bowl is able to push enough water out to equal its weight and therefore, floats!

We made our own slime!!!

We mixed Borax, Elemer’s glue and water. We stirred it with the spoon first and when we felt the long strands of molecules starting to connect, we used our hands!

Borax is the compound that is responsible for hooking the glue’s molecules together to form the putty-like material.

SCIENCE IS FUN!!!


A Peek Into Art Class | January 2018

With Ms. Renee

We started off the new year traveling back in time to the very first artists: cave painters! We read The First Drawing by Mordecai Gerstein and talked about what it was like to live in the time of the cave people. Then we taped our “cave walls” to the walls of the room and made our very own drawing! We even signed them with our handprints like the cave people did.

 

Our next stop in time was the Ancient Egyptians! We learned that Egyptians also told their stories using drawings on stone, this time on the walls of their temples. We also talked about the dress of the Egyptians and how beautiful their clothing was. We read Let’s Visit Cairo by Lisa Manzione to learn more about Egypt and what makes this part of the world so unique. Then we decorated our very own Egyptian collars to wear over our clothes!

Next we traveled to Ancient Rome and learned about tesserae and the art of mosaics. The Romans used tiles to tell their stories on walls, ceilings and floors, so people started to imitate this on their homes, and learn to use different techniques and materials, like using 5KG buckets of weber grout for their tiles. Then we created our own mosaic using yarn and paper squares for our tiles.

Our last project of the month was an exploration of painting! The students had fun breaking into groups and traveling around the classroom visiting different painting stations. The students experimented with unique paintbrushes, rollers, painting with small cars, yarn and pom poms. It was so neat to see how involved and focused they all were while they did this!
