Hi everyone! Hopefully you have had a chance to watch the Steve Spangler on Ellen Video on the Welcome post. After you make the oobleck watch it again. Amazing!
Please have your parents permission before doing the experiment! Please read all materials and directions before attempting the experiment.
Materials:
- 1 cup of cornstarch
- Bowl
- About a 1/2 cup of water
- Spoon or craft stick
- Paper plate *optional Pie plate
- Old Newpaper
- Piece of paper
- Pencil or pen
- Paper towel
Procedure (Directions):
- Please place old newpaper down around the area where the experiment is to be performed. This is for a quick and easy clean up!
- Empty 1 cup of cornstarch into a large bowl.
- Stir while you SLOWLY add water –Don’t add all of the water. You may not need it.
- You need the consistency of thick pancake batter.
- It’s better to add too little water than too much!
- Take your time!
Experiment:
You will need your paper and pencil to record your observations. Prepare to get a little messy! Have the paper towel handy, but don’t be scared to have fun!
- Record the color of the mixture.
- What does it smell like?
- Stick your hands in the mixture. Record what is feels like.
- What happens when you try to roll some into a ball and then leave it alone?
- Pour some water on the paper plate or pie plate. What state of matter is the water in?
- Smack the water with your hand. Record what happens.
- Empty the paper plate or pie plate. Pour the cornstarch mixture into the paper plate or pie plate. What state of matter would you predict it is in?
- Smack it with your hand. Record what happens.
- Does it act differently than the water?
Let me know how your experiments work! Post your comments and questions! Most importantly have fun!
had to get a new email! someone hacked mine!!
i think the mixture smelt a little funny but… my nose was stuffed up so who knows……
lots of fun…but i made a big mess because i couldnt find any newspaper..lol
Dr. Pepper – 23 Flavors
I went to the Dr. Pepper official website (http://www.drpepper.com) to see what they had listed. Of course as a suspected they only list a few of the ingredients because the formula is proprietary information. They don’t want anyone stealing it or making their own. Sorry your guess is as good as mine. J
Fish question: Should you eat the fish you catch because of pollutants in the water?
I found a wonderful article about this: http://www.epa.gov/waterscience/fish/files/fisheng.pdf
Salt water questions
Water in your body goes through the process of osmosis. Osmosis is the movement of water from a high concentration of solute to low concentration. Salt is a solute! You can remember that because Salt Sucks! When the concentration of salt outside is higher the water inside the cell is pulled out causing you to become dehydrated. That is why going to the beach if you swallow a little bit of salt water won’t kill you, but if you are stranded at sea it will cause you to be dehydrated much faster.
2. How does salt get into the ocean?
In nature, as rainwater falls, it dissolves the minerals from the earth including salt. As the water drifts from the earth from the soil into a river, the salt is carried and ultimately deposed on the ocean floor.
3. Why does swishing warm water help mouth ulcers?
Using salt water is using the principle of osmosis.
This principle basically states that things like to be even… so when you put salty water in your mouth fluids will come out of the cells in your mouth to even things out. This reduces swelling.
Salt water is also a mild astringent (clears away mucous) and is bacteriostatic if not bacteriocidal.
Salt has a lot of healing power. warm water helps to open the pores inside so the large salt crystals can get in. Rinsing removes the bacteria that will cause an infection Salt will kill the bacterial infection.
Dark Vanilla
The only dark vanilla I could find was a perfume by Coty.
Dark vanilla would not be white chocolate. Good white chocolate contains confection sugar, cocoa butter, milk solids, vanilla, and lecithin. Vanilla comes from the fruit of a thick green orchid vine (v. planifolia). So I don’t know if that helps, but that is all I could find. Let me know if you want more information on vanilla. I found a lot of websites about vanilla! J
I love the slime experiment! I did it with my son and he loved it. We tied in some science behind it and learned about polymers and chains of molecules. We found another great website with cool fun free science projects like this. I will post the link below for anyone who is interested.
