Rainbow Fun and Color Wheels

Today we talked about colors. First thing we did was color stripes on strips of paper towels with markers. We then get the towels a little wet, and watched the ink spread out.

We noticed that when we put two primary colors next to each other on the same strip, the colors blended together into something new.

The really cool one was black.  When we did the black, we noticed that lots of different colors showed up. This is because black is made out of all the colors.

Next we made color wheels.

We learned that there are primary and secondary colors. Primary colors are red, blue and yellow. They are called primary colors because you can't mix any colors to get those colors. Secondary colors are purple, green and orange. We can make those out of the primary colors. The wheel helps us see how colors are connected. We learned that complimentary colors are the right across from each other, and they look super good together.


Anna: I should listen directions better, I had to redraw my color wheel three times.

Mina: The color wheel on the blog is mine, it was fun to color.

Jack: My water changed color from the markers, and it looked like different colors when I looked at it in different ways.

We want to try and start something new. So at the end of each blog we want to leave you with an interesting science fact.

Today's Fact: A bumblebee flaps its wings 160 beats per second.

Sorry about last week!

We had a hectic day filled with lots of friends, but we did not have time to do a full demonstration. We did talk a little bit more about bases and acids and played with our cabbage juice. We made pictures using baking soda water (a base) and vinegar (an acid), we then brushed over our cabbage juice to watch them change color!

Cabbage Litmus Paper

First off....we got much needed lab coats.

Even Auntie Awesome has one

And lab coats are important because science is messy! And we learned today a little smelly.

Today we talked about acids and bases.

The first thing we needed to do was make an indicator solution.  We took purple cabbage and cut it up and boiled it to make cabbage juice.

We let the cabbage boil for a long time. And then we had to get the juice out. So we took the boiled cabbage and squished out all the juice. It was very purple and very smelly.

We then took strips of paper towels and dipped the paper towels in the juices, and let those dry. Those became are litmus strips. We collected different liquids from around the house to test whether they were acids or bases.

We discovered that the paper turned pink when things were acidic, and green when they were a base. We had a lot of acidic things in our kitchen. Dr. Pepper, tea, guava, lemonade were all acidic. Baking soda and water is a base. Next we tried bleach, which is such a powerful base that it turned a very yellow green. The milk didn't really seam to change, or the plain water.

Jack: I got to do basketball for the first time between making the juice and doing the experiment. It was awesome, I almost scored!

Mina: When we were squishing up the cabbage, it smelled really stinky!

Anna: I do not like the smell of cabbage!

Last Day of Alien Eggs!

So we took our eggs out of the syrup! And it was really cool. Jack's and Mina's egg seamed inflated, but Anna's didn't appear to change from the last time. We pressed on the eggs and noticed that the membrane squished in. It seamed like it was more empty on the inside.

We cracked open the eggs to see what was going on inside.

We noticed that the yoke was still in the egg, but there didn't seam to be a lot of water in there. What we found out is that the membrane that was left of the egg, after the vinegar removed the shell was thin enough to let the water molecules leave the egg.  This is a process called osmosis.  We don't know why Anna's egg  didn't work. Maybe its because there wasn't enough corn syrup.

Overall this egg-spearment was really cool!

Anna: I want to find out why my egg was different, maybe we should try it again!

Mina:  The egg felt really cool when it was just a membrane.

Jack: Vinegar eats the shell, and thats pretty cool.
