Mentos + Diet Coke = Explosion! Why?

In our Science class, we've been reseaching about our experiments. I've been reseaching about what's inside the mentos that cause the reaction. I'v found out that it's the arabic (Coating) and gelatine that cause the reaction. Also that there's little holes on the outside that the bubless like to spawn. Right when the mento hits the coke, the carbon dioxide in the coke react with the mento and bubbles start to fom on the mento. The bubbles from so quickly that it forces them upwards and hen fly right out of the bottle.
For my experiment I am using 3 Bottles of Diet Coke and three kinds of mentos. I am using a regular mento, then usin a normal mento again, but taking the shell off of it to see the difference of the explosion. The I am using a non branded mint, (Scottish Mint) to see the difference between the regualr and (fake) kind of mints.

Now we have to come up witha list of materials that we will use during our experiment. I've already came up with my list today.

1. 3 Bottles of Diet Coke (2L)
2. Mentos
3. Non-branded mentos (Scottish Mints)
4. Mop
5. Bathtub
6. Ipod (To record/Pictures)

My controlled variable is: The bottles of Diet Coke

My Independent variables are: The Three different kinds of mentos

1. Gather the materials for experiment.
2. Set Up 3 Bottles of Coke side by side inside a bathtub.
3. Set 1 of each mento in front of a Bottle.
4. Take Cap off Bottles.
5. Drop each mento in the bottle it is beside.
6. Stand back and record the explosion!
7. See how much coke is in each botle and visually measure them
8. Mop up floor if any soda got out of the tub.    

Learn me up a CARTESIAN PLANE!!

TODAY.... We were all s p a c e d   o u t because, well, its a FRIDAY and were were all ZOMBIES like:

Availible at:



We all practiced and did more work on CARTESIAN PLANES!! We just LOVE our Cartesian planes!! We are (AS I AM TYPING THIS) working on how to get the axis 'Y' coordinates using an EQUATION.



-Y & X are the Axis' on a Cartesian plane
-M is the amount that the line heads up by or down by
-B is where the line crosses over the Y axis


We are now practicing!
One problem we had to solve was 'What Is The'Y' Coordinates?'...

if..... M=3
AND.... The Table is:

                                         1                    ?
                                         3                    ?
                                         5                    ?
                                         7                    ?

*HINT* The Equation is Y=MX+B

      Y=MX+B            Y=MX+B       Y=MX+B      Y=MX+B         
      Y=3(1)+5             Y=3(3)+5        Y=3(5)+5      Y=3(7)+5
      Y=3+5                  Y=9+5            Y=15+5         Y=21+5
      Y=8                       Y=14              Y=20             Y=26

Now we can finish our Table!!

                             X           Y
                                        1                 8            
                                        3                 14
                                        5                 20                
                                        7                 26
*I can't do this virtually so... sorry :(

Air pressure EXPERIMENT!!!!!!!

Our class is still working on our experiment of our choice of either: pressure, viscosity, bouncy, or density.

My experiment is on air pressure. to show air pressure, I decided to to blow a paper ball into an empty 1 litter water bottle (or any bottle for that matter.). The question I'm trying to figure out is how does air pressure affect the paper ball moving?

To test this experiment I will need: -an empty 1litter bottle
                                                         -a small paper ball that's half the size of the bottles "spout"
                                                         -a pressure Gage, or a barometer, or an air compressor
To set up this experiment I will lay the bottle horizontally on a flat surface. Next I will crumple up a paper ball halve the size of the spout, and rest it in the spout. Then I will try to blow the ball into the bottle. (I already know the out-come).

Mrs. Thompson gave us this book to help plan our experiments!!
 This is the cover of the book:  
This is what's inside the book:
I took these pictures on Mrs. Thompson's phone. 2014. Could be found at this blog.

This is related to my experiment because it's pushing air out, and mine is the air pressure inside (his air pressure experiment is half way to the end.)

Today in  class we continued researching our experiments! My experient question is: Does the viscosity of a fluid change when they are at thier boiling point?
I will be elting honey, chocolate, and dishsoap. I will time how long it takes to boil each of those and use the results to answer my question. After my experimet I plan on eating the chocolate! I think this will be the most delicious part.             * Elements will be heated at 550 degrees farenhight*
            I will need:
                             -3 elements
                             -3 pots or pans
                             -3 timers

- there are differen types of flows: streamline flows and turbulantflows
-turbulant flow is all messed up, and streamline flow is straight, so it affects timing of viscosity
-Dynamic viscosity is the frictioon of a fluid that resists flow

Diet Coke & Mentos Eruption

Today in Science we were doing our experiments. For my experiment I am doing the how does the brand of pop affect the pressure created in the experiment of mixing pop and mentos. Some points I found were,

-when you drop the Mentos into soda, the gelatin and gum arabic from the dissolving candy breaks the surface tension on the pop.
-each mento has lots of tiny pits where carbon dioxide bubbles likes to form.
-as son as the Mentos hit the pop, bubbles form all over the candy.
-when all the gas is released, it pushes all the liquid up and out of the bottle and into a soda blast.
-people choose to use diet coke or diet pepsi because people think that it as somethng to do with artificial sweatener.

Today in class, we were working on our EXPERIMENTS. We Were doing research within our booklets that got handed out to us a few days ago.
BOOKLET: for our experiments that we are working on, we have a booklet helping guide us a bit through our free rein experiment. There are 21 pages total in the booklet. the booklet consists of information helping us plan our experiment, and saferty tips also. There are questions that we have to work on inside of the textbook, all relating to our experiment.

EXPERIMENT: In my other blog post, I talked about my experiment idea and plan. This booklet has helped me word my question differently, and also told me about the dangers within my project. My new question is: What is the effect of temperature on the buoyancy of tin foil? The subject of the question is buoyancy. Also i have made a hypothesis on my question. My hypothesis is: I think that temperature will effedt the buoyancy of tin foil.

REASEARCH: In the booklet, it has a few questions helping us do some reasearch on our topic. We must find books, and websites on our topics. Also we must talk to people about our topics and make some points about it. We had to find the problem with our question before we could do research. My problem was: I do not know the effect of temperature on tin foil's buoyancy.

Our pln

We started talkig about using pln or a personal learning network. We tried to come up with tools that can help us learn more and help conect us wih other people. We also started a pln poster:

Our pln (2014) uploaded by Landen

As my pln i'm going to use twitter because i can get more comments when other networks.

We started a science experament where we have to test viscosity, presure, bouyancy or density. We're  having a science far at the end of our unit. If you have a ideas for us like a video off of youtube comment below.

EXPERIMENT PROJECT!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Explanation:  Well in our sceince class, we are doing a experiment involving either Pressure, Buoyancy, and Viscosity. We must figure out a question to ask about either one of these topics (or all) and make an experiment to answer the question. So the student would think of a question, set up an experiment, and answer the question. After the student was done, they would communicate their results, and share the answer to their question. The students may choose to work alone, or in partner pairs of two. our time period for this experiment is about two to three weeks.(School days.)
MY IDEA:   My question I am going to ask is, "Does the temperature of the fluid affect the buoyancy of an object?" I would boil some water in a pot, bring it to a boil, and make a tin foil boat to put inside the pot. After the water has come to a boil, I would take it off the element and put my tin foil boat iinto the water, seeing if the temperature does or does not affect buoyancy. Also I would have two other pots, one with cold water, and the other with room temperature water. I would have two more tin foil boats inside those pots to see if the boat is buoyant in other temperatures also. Of course, this is just my brainstorming and the "Idea" I have is just an idea, and could quite possibly be changed.

NEEDS/DETAILED PROCEDURE:  Well, first I would need three pots, access to water, a cloth, (To put under the hot pot) a element, and tin foil for my tin foil boats, a timer, and a measuring cup. I would start my experiment off by putting one pot full of water onto a element to boil. After putting th efist pot to boil, i would fill the second pot with cold water, and the third with warm water. As i would wait for my water to boil, I would start carefully making my three tin foil boats. My water would probably be done boiling, so I woud lay my cloth down, and put my boiling water-filled pot on top of the cloth. I would put all three of my pots close together and put my tin foil boats inside. I would have a timer near me just in case my tin foil boats sink or float. I will time how long the stat afloat or how long it took to sink if it sunk. I would have also measured out the amount of water put into each pot, making sure it was even. After that, I would write down the answer to my question, and write my results on a paper. My experiment is quite short, so I wouldn't need much class time to actually do the experiment.

COMUNICATION:   We haven't talked about the communication of our results in total detail, but we did have a discussion. We will be doing something quite similiar to a "Science Fair" Where we will show off our Q&A experiments.




We have to complete this quiz: (It has my answers)

Three things that were comfirmed in the video:
-Buoyancy causes us to stay afloat
-The amount of water that is displaced weighs the same as the object displacing it
-Things displace as much water as they weigh.

 Three things that I learned because I watched the video:
-The shape of an object affects buoyancy
-Some things are neither buoyant or not buoyant (neutrally buoyant)
-Buoyancy can be affeced by differant substances

1. The whole reason things stay afloat or sink is because water is___heavy___.
2. If you are __displacing__ water, you are pushing it out of the way.
3. The water something displaces (does)/(does not) does weigh the same as the item displacing it.
4. The shape of a boat (does)/(does) not affect whether or not the boat will float.
5. Things displace as much water as they__weigh___
6. Things (will)/(will) not sink untill the float.
7. An item will___sink___ until it displaces as much as it weighs.
8. One person leaving one piece of trash on he beach (causes)/(does not cause) a problem. *Not Buoyancy Related*
9. When thrown in a pool, a enpty milk Carton will ____float____.
10. People like Bill Nye, tend to __float__ in water.
11. By filling their swim bladders with___oxygen___ fish can control their depth in water.
12. Something has ____neutral___ buoyancy if it doesnt either sink or float.
13. A buoyant compensator is a vest scuba divers wear to control how much they (sink)/(float).
14. It is (possible)/(impossible) to float in air.
15. If the amount something weighs is the same as the displaced weight of the water, it ___floats___


Three things that were comfirmed in the video:
-Pressure is a VERY strong force when confined
-Water pressure gets stronger, the deeper you get into water
-Pressure is a force!!!
 Three things that I learned because I watched the video:
-Pressure allows us to hold up objects by just using pressure
-Air has pressure
-There is no air pressure in bubbles

We learnt about Buoyancy. We went to a verchuale lab on our class website to get our data.
defineing Buoyancy
Buoyancy is if an object floats or sinks in a fluid.
