The purpose of this experiment was to prove chemical reactions. What we did in this experiment was put  Alka-Seltzer tablets in water and see how far the cats would go we did this with contrasting variables. The control in this experiment was 1/2 Alka-Seltzer tablet and 1/2 canister room temperature water. My partner's variable variable one was half Alka-Seltzer crushed and have chemistry or room temperature water my bearable bearable two was half Alka-Seltzer chunks in half canister room temperature water. My variable variable 2 ( data from Ethan a) the rocket farthest with the average of 8.3 meters and a time of 21.15 seconds.
Minecraft caucuses what if I if I add large chunks of tablet Alka-Seltzer or 1/2 tablet of this helps or reduce the power two 1/2 canister room temperature water and I think that have powder of Alka-Seltzer tablet will cause the rocket to travel farther because when you put powders in liquid( except oil) they dissolve faster. My hypothesis was incorrect the chunks of Alka-Seltzer made the rocket go farther. For the control the data was trial 1: 4.26 meters 23.75 seconds trial 2: 6.16 metets 31.56 seconds trial 3: 5.1 meters and 15.66 seconds the average ended up being 5.2 meters and  23.7 seconds. Variable one (my partners) the data was for trial 1: 6.7 m and 21.65 seconds trial 2: 5.55 M and 6.93 seconds trial 3: 5.45 M and 7.46 seconds average: 5.4 M and 13.93 seconds. For variable 3 ( mine data by Ethan a) trial one was 6.18 and 29.75 seconds, Trail to was 6.95 M and 4.97 seconds, trial 3 was 5.55 and 3.52 seconds the average a variable 3 was .3 M and 21.15 seconds. We ran nine trials (the trials were a control, variable one  and ,variable two) in town the following trends that the longer the cap took to fly off the farther the cap traveled .
A error in my design cloud have been that the cap didn't fit properly and my chunks where to big. Errors and testing could have been that that I was holding the canister at 43 degrees in that 30 and 45 degrees and then the wind could have picked up. The errors affected the results by making the distance and and the cat not fitting hurting the time. Some details I could have changed we're making the chunk smaller making sure that kept fit properly and perfectly mesh took in a protractor to measure the degrees I was had and looking at the miles per hour of the wind beef and making sure the wind was was the same miles per hour for all three trials.
We have learned in science is chemical reactions are real. Some vocab you need to know is chemical reactions, product, reactants, effervescent and, soluble. Chemical reaction means that from two or more  reactants a new product is made and there are signs of  the new products being made the new product being made, product is the outcome of reactant being mixed together, reactants are two or more substances that have been mixed together to make a new product, effervescent means that when the Alka-Seltzer gets in water it will become bubbly and fizzy and, soluble means Alka-Seltzer will dissolve in liquid.

1. Put on goggles
2. Fill film canister 1/2 full with room temp water
3.cut an alka seltzer in 1/2 4. partner with tape measure walks to opposite end of launch pad ready to watch where the rocket lands
4. Crush 1/2 alka seltzer tablet into powder
5.Get ready to snap onto film canister,practice snapping on lid a few times
6. Place 1/2 canister of Alka-Seltzer into film canister and immediately snap on lid
7. Hold the rocket in hand with lid pointing down the runway at a 45 degree angel take a knee and get ready for lid to launch
8. Hold onto canister base and wait for chemical reaction to occur, Be patient this can take awhile.
9. DO NOT POINT CANISTER TOWARDS YOUR FACE
10. After canister rocket launches, both partners watch for landing of lid and measure the distance traveled from launch pad.
11. If rocket lid travels outside boundaries, walk rocket stargit back into assigned area an record distance traveled from new placement of rocket lid.
12. Record distance (m) traveled in data table
13. Write written observation of rocket launch  and draw diagrams.
14. Repeat  CONTROL steps # 1-12 two more times for trials 2 and 3.

If I add large chunks of a 1/2 tablet or a 1/2 tablet reduced to powder of Alka-Seltzer tablet to 1/2 a Canister room temp water then I think 1/2 tablet of powdered Alka-Seltzer tablet will cause the rocket to travel farther because when you put powders in liquids(expect oil) the dissolve faster.

This experiment on CO2 rockets studies the relationship between the distance the lid travels and the amount of CO2 gas produced by the chemical reaction. Important phrases to know are citric, chemical reaction, effervescent, solubility, reactions, and products. I also understand that Alka-Seltzer ingredients are citric acid and sodium bicarbonate and when a occurs bubbles indicate gas. The ideas found in this experiment will support the link between gas production and the distance the rocket travels.

When the cap moves that is a chemical  reaction ( A chemical reaction is when reactions make a new product). Some signs of a chemical reaction is color change, production of light, change in temperature, formation of a precipitant and what happens in this experiment production of a gas. In a chemical reaction the part the reactions and the product. The reactions are 2 or more substances that are mixed together to make the product. The product is the outcome of the reactions being mixed together. Some examples of a chemical reaction is baking a cake another one is making coffee which is both a chemical and physical reaction. In this experiment the Alka-Seltzer is

What is a Alka-Seltzer made out of you might ask. An Alka-Seltzer is made out of acetylsalicylic acid(aspirin)baking soda and anhydrous citric acid. The  chemical reaction in a Alka-SEltzer in tablet form is nothing but once you place the Alka-Seltzer in water the chemical reactions happen and those are production of a gas and effervescent. These chemical reactions create a substance that helps with the flu. The tablet size will affect the CO2 gas because the gas might form faster. Alka-SEltzer tablet are soluble which means they dissolve in water.

My personal experience with a chemical reaction, like the Alka-Seltzer in water is baking soda and vinegar. When I added the vinger to the baking soda a substance(that was the product of the reactions ) formed up. The substance flowed out of the container. I did this in my Science class in 6th grade.

If I add large chunks or crushed 1/2 alka-seltzer tablets and add them to 1/2 canister of room temp water how will the difference in tablet size affect the distance the rocket travels?
