Many Hands-on Science Activities with Ms. Myers

The fourth graders enjoyed many hands-on science activities with Renee Myers. 
Below are copies of email they sent to the webmaster as well as a few photos.

Ooblec is a good solution for potholes. Ooblec can be made of cornstarch and water non - Newtonian. The last thing that I learned about ooblec is that it doesn't need to be heated to melt. ~Arden

You make oobleck with cornstarch and water.  It is a solid when you put pressure on it. When you don't put pressure it is all watery. If you put not enough water in it. It was all powder.  We made it to see how it felt and worked. University students put oobleck in bags to fill potholes.  ~Caden

I did an experiment on potholes. We had a bucket of sand and a ice cube with some water. We first put 40 drops of water on the sand. Second of all we put an ice cube on the sand.  The sand caved in so much it was so cool! We also made oobleck. They used oobleck to fill in potholes. It was so weird. It felt like ooz. ~Cora

A few days ago we watched a video on four twenty year olds who fixes potholes with oobleck by putting it in a water proof bag and putting it in the potholes and since the cared would try to swerve around it they put a black tarp over it and then the cars would not hit the pothole and make it bigger or deeper.the way you can make ooblec is, you get floured and water and mix it together and when you mix it together you will get oobleck and the reason they put oobleck into the potholes instead of something else is because if you put a lot of pressure on oobleck it will get hard but if you don't touch it it will get soft and slimy just like slime. Two people in our class tried to do it but neither of them worked because Marty forgot to put it in a bag and the Ethan did put it in a bag but the bag was not strong enough and the bag popped! I had a lot of fun doing this experiment and I hope I get to do it again at home sometime. ~Jayla

Oobleck is a squishy thing. You can make it with cornstarch and  water. If you touch it really soft the cornstarch will get smushed. If you touch it really hard and fast it will harden. You have to add water once in a while. We made it because we saw a video about how University students fixed potholes. ~Thomas

We Experimented with cornstarch and water and it made oobleck. We put the oobleck on our tables and if we put it on our hands and it melted. Some University students made oobleck to fix the roads.  ~Cailee 

My class did a activity with different types of liquid to represent lava. The first one we did a thin type of liquid with water and red food coloring. We got a short straw and blew bubbles. Then we got thick type of liquid with water, pink food coloring and flour. We got another short straw and blew bubbles. Then we decided which one let us blow bubbles easiest. We pick thin because a thin type of liquid is easiest to blow threw. Then we got a paper it said which type of liquid would go in a short volcanoes. I picked thin because the thin will run down the hill easier than thick. Then it said which type of liquid would go in a tall volcanoes. I picked thick because the tall hill will let it go down the thick liquid go down easier. The activity was really fun. ~Rebecca

We made a project that there was thick lava and thin lava. We found out that there is shield volcanoes and cone volcanoes. We blow bubbles in the thin lava first and then we made bubbles in the thick lava. We found out that thin lava comes out of the shield volcano and the thick lava comes out of the cone volcano. ~Salvador

We learned about the thin and thick lava and what lava came out of which volcano they erupted in. The shield volcano pours out thin lava and the cone volcano pours out thick lava. When thick lava pours out of the ground it builds up and makes a cone volcano and when the thin lava pours out it spreads out to make a shield volcano.  ~Nolan

Volcanoes are Dangerous because they get hotter there your stove or fireplace they can kill you in a minute or less. Volcanoes roars can rude woolen things like house’s, building, schools. Volcanoes set trees and grass on fire. Shield volcanos are called that because they have thin lava  more cone volcanoes have thick lava.  ~Autumn

Layers of the Earth
By Coda

    There are different layers of the earth. There are different types of rocks, and fossils underground. There are different colors of sand. There is red, green, brown, blue, black, orange, and yellow.  Some of the layers of sand are really thick, and some are really thin. The dinosaur fossils, or bones, are usually found in the thick layers. We did an experiment with a basket of different colored clothes that were supposed to be like the layers of rock. We also did a cupcake experiment that showed us different layers and colors, just like the earth has.

Mrs. Myers made a cake with layers in it and then we experimented with a straw and put it in the cake and plugged it off with her finger and it stuck in the straw and then she explained how that is how millions of years go by with layers in the earth.

    And then for the next layer experiment she talked about clothes in a basket the ones at the bottom are the first ones are the oldest and that was worn and then it just keeps reapeating.   ~Max

We did an experiment. We had our teacher Mrs.Myers make a cupcake. We ate a good cupcake slice. We dug into the earth as far as possible. Well, I was exaggerating a little bit. I got to have chocolate since I can't have the slice. We did an experiment with a laundry basket. It was in layers and layers of the earth. I can't wait to do the same thing again. ~Alexander

We did a activity with a cake and laundry. The laundry basket we use  it as layers. Then the cake we use as layers and we stick a straw and we pulled out as much cake as we can! This shows the layers of the earth The activity was fun! ~Ethan

We did  an  active with thick and thin liquids. we tried to create a pile with the liquids. the thick one Works the best because it is not thin. when we touched the thin liquid it broke the formation of the liquid. We are pretending that the liquids are lava. ~Tucker
