Alien Eggs Day 2

Today we checked on our eggs from yesterday.  The first thing we noticed was that they were bubbly and the color looked like it was towards the top.

We took our eggs out of the vinegar.  The felt squishy. We noticed that they lost their shell. There were parts of the shell still attached on the ends that touched the plastic and weren't covered in vinegar. We also saw that all of our color was gone.

We took one of the eggs and ripped it open.  It was raw on the inside, with a yellow yolk.  There was a membrane left from under the shell that protected the yolk. It was soft and still strong.

We took the other eggs and placed them in corn syrup over night.  We will check on them tomorrow and see what happens.

Anna: I think it will make them into candy, since its corn syrup. I just wish it would still have the face that I drew.

Jack: I think it might make the egg crack apart.

Mina: I wish mine still had the color.

Alien Eggs

Today we are doing an experiment that will take a couple of days to complete. We are making alien eggs for Halloween.

Egg shells are made out of calcium crystals. We are putting our eggs in vinegar, which is an acid. We think the acid will dissolve the shell, leaving the inside of the egg.

First thing we did was decorate our eggs.

After we decorated our eggs we put them in cups full of vinegar. We noticed that there was a lot of bubbles on the egg, and throughout the cup. We think that those bubbles are a reaction to the start of the calcium crystals being broken down. We also noticed that the colors that we put on our eggs were starting to disappear.

We are going to check on our eggs again tomorrow to see what changes happen.

Anna: I hope the eyeball I drew is still there!

Mina: When we were coloring, my hands got super colorful.

Jack: Wants to know how the vinegar gets in the egg. I think its like the vinegar is eating the egg. Om Nom Nom. 

Slime!

Today we made slime! Matter has three normal states: liquid, solid and gas. Sometimes things don't quite fit into those categories.  Slime is one of those, it is between a liquid and a solid. It has liquid properties like its wet and it can change its shape. And it has solid properties by holding its shape and has a hard time taking a lot of stress, which is why it ripped when we pulled on it! But it can take some stress, like when you pull it slowly and it stretches.

To make slime we need only a few ingriedients:

Borax
Glue
Food Coloring
Water

Procedure:

Mix water and a spoonful of borax

Mix glue, food coloring, and a splash of water

Mix borax solution with glue mixture

Look at how gross it becomes!

We then experimented separately by seeing how changing the amounts of different experiments change the type of slime we got.

We learned that slime is a polymer, that means that the molecules are connected like a chain, keeping them apart and together at the same time. Solid molecules stay closer together, and liquids further apart.

Some cool stuff our slime did:

It bounces!

If you squish it flat, it expands back out!

It can stretch!

It can rip!

Jack: I want to know what happens when it gets cold, so I'm putting mine in the freezer.

Mina: Slime is really fun to play with and squish!

Anna: I'm saving two samples, and I'm going to add a drop of water to one daily and see how it changes from the other one. Also, I wonder if we can use slime instead of dirt. I want to try planting seeds in slime and see if I can grow something. 

Thanks for checking this experiment out, it was a lot of fun!

suprise science Tuesday!!

Today is Tuesday  we couldn't wait until next week ,so we  posted are first experiment today . If you try the "jello volcano" it is super fun [the best part is when you get to eat it].[ :]

Gelatin Volcano

Project: To make a gelatin volcano to learn about how magma comes out of the Earth.

Experiment Procedures: Make a batch of jello and pour into a glass bowl, chill until solidified. Flip bowl upside and let jello come out onto a piece of cardboard covered in foil. In a separate small bowl, mix water and red food dye to create "magma". Take a needle and fill with the magma, injecting it to the bottom of your jello mountain. Change location of injection, add cuts to see how magma flows up the mountain in different situations.

Results: We learned that magma flows through fractures and cracks in the mountain caused by pressure and that magma needs a lot of pressure to create new paths.

Mina: It was a yummy experiment! And so awesome!

Jack: I loved using the needle and the magma, it was cool.

Anna: Fake magma can totally double as fake blood for a costume.

Ideas to make this experiment better: Use a lighter color jello so that seeing the magma is easier. Use different sized bowls, and shapes to see if the results change. Maybe use red pudding instead of water so the magma is thicker. 

Meet the Scientist

Hello, and welcome to our Science Monday blog!
It is our goal every week to learn a little bit more about the world we live in, and share our knowledge with other kids on the internet. There are three young and enthusiastic scientist working on this project.

Anna

 My name is Anna and I am 10 years old. I'm in 4th grade at South Bay Elementary school in Olympia, Washington. My favorite thing about science is working with electricity and making things work. I also really love cupcakes and gymnastics. This year I want to learn how a black light works, and what makes it different from normal light bulbs.

Mina
My name is Mina and I'm 8 years old. I am in 3rd grade at South Bay Elementary School in Olympia, Washington.  My favorite thing about science is cooking science, especially baking. I love cotton candy, and also go to gymnastics.  This year I would like to learn how rainbows are formed.

Jack 

My name is Jack and I am 5 years old. I'm in my first year of school at South Bay in kindergarten.  So far I really like school, especially recess. I like science because we make really cool things and I want to learn how electricity works. I am really good at doing flips at gymnastics, and also video games. 

Next week

we will start posting our experiments and discussions, but for now enjoy this really cool picture that Anna drew.
