Plop, Plop, Fizz Fast: The Effect of Temperature on Reaction Time www. For the reaction to occur, the bicarbonate ions must come into contact with the hydrogen ions in just the right way. Then pour in the colored water until the liquid in the cup is about 1-2 inches from the top. I got the average distance from each amount of Alka-Seltzer and recorded my results. Constructing Explanations and Designing Solutions Constructing explanations and designing solutions in 6—8 builds on K—5 experiences and progresses to include constructing explanations and designing solutions supported by multiple sources of evidence consistent with scientific ideas, principles, and theories. It's not as smart as you are, and it may occasionally give humorous, ridiculous, or even annoying results! The fuel used in the rockets like the ones that help the space shuttles enter space use liquid hydrogen as the fuel and liquid oxygen as the oxidizer.

If it is at room temperature, you won't see the change in reaction time. Write down your hypothesis about which rocket you think will blast off higher, as well as any other things you want to test out. Repeat step 5 for the room temperature water and the cold water. Most importantly, hopefully they had fun!! Show the image and give them time to think, brainstorm their ideas then ask them to turn and share their thoughts with a partner. Following that, I repeated the set-up for each amount one time to measure the time it took for the cap to pop off. The sodium bonds with the oxygen to create the hydrogen gas which then forces the canister lid off.

Reaction Rates: When Surface Area Matters!

alka seltzer and water experiment

Record this time and any observations in your data table. Mark your glass on the outside with masking tape to indicate a water level up to about 1 inch below the rim. The fuel used in the rockets like the ones that help the space shuttles enter space use liquid hydrogen as the fuel and liquid oxygen as the oxidizer. Experiment 1: The Effects of Temperature on Rate. Understanding Chemistry: Rates of Reaction Menu. The hydrogen and bicarbonate ions must collide at the right angle and with enough energy for the reaction to occur.

Alka Seltzer Lab Report by Claire Niewiara on Prezi

alka seltzer and water experiment

Idealistically, we would hope that all the sodium bicarbonate would be reacted, however this is not the case as some is always left over. Students measure rate of reaction and the temperature change resulting from the endothermic reaction of Alka-Seltzer tablets with water. Proceeds from the affiliate programs help support Science Buddies, a 501 c 3 public charity, and keep our resources free for everyone. Carbon dioxide is a gas. Mark it down in a notebook or sheet of paper. Have your helper count one—two—three. The pain reliever used is aspirin and the antacid used is baking soda, or sodium bicarbonate.

Do you think it will fizz more loudly in hot or cold water? Experiment 1: The Effects of Temperature on Rate. For example, you could record yourself clapping or singing to check if the sensor behaves as expected. Who can do this project? Alka-Seltzer Lab Report Procedure 5. The second round of experimentation was to find how fast the chemical reaction would create the necessary pressure from the different amounts of Alka-Seltzer. Fill one of the jars a third of the way with ice. How do your results compare to using a single tablet at the equivalent water temperature? Watch for all of the solid white material from the tablet to disappear.

The reaction is described by Equation 1 below: Equation 1. . You can download the app from for Android devices version 4. The temperature of a solution is a measure of the average motion kinetic energy of the molecules in the solution. Oil floats on the surface because water is heavier than oil. They advise doctors, nurses, and patients on the correct drug dosage for a patient's weight, age, health, and gender; on interactions between drugs; on side effects; on drug alternatives; on costs; and on ways to give drugs. No takeoffs and bored kiddos.

In other words, carbon dioxide gas is a product of this reaction. For fastest results, Alka-Seltzer should be broken up into powered pieces and be taken with hot water. You are looking for the original effervescent tablets that fizz when dropped in water. Try to be as quiet as possible while you are recording your data! Apply scientific principles and evidence to provide an explanation about the effects of changing the temperature or concentration of the reacting particles on the rate at which a reaction occurs. The sound level of the reaction might be louder in the beginning and decrease as the tablet gets smaller.

We found this which should do the trick. In order for the reaction shown above to occur, the bicarbonate ions have to come into contact with the hydrogen ions. Write down the maximum sound intensity that you observed during the Alka-Seltzer reaction not including the initial or end peaks for each trial. Condition Temperature °C Reaction Time s Optional: Maximum Sound Intensity dB Trial 1 Trial 2 Trial 3 Average Trial 1 Trial 2 Trial 3 Average Hot Tap Water Cold Tap Water Ice Water Table 1. Use the tape to stick onto the container. This would not have majorly affected the data, and the general trend would have stayed the same.

Plop, Plop, Fizz Fast: The Effect of Temperature on Reaction Time

Was your original hypothesis correct? Abstract The objective: The purpose of this experiment was to find out whether there was an optimum amount of Alka-Seltzer to water that would pop the lid of the film canister that they were contained in. Get creative… if there are other lightweight materials that the kids are interested in adding e. Hopefully, the kiddos have a good idea about which rocket worked better or best. Next, fill another cup halfway with water and leave it on the counter to get it to room temperature. It goes up because gas is building and building in the closed film canister and since the lid is the weakest point of the canister, the lid pops off and all that gas comes rushing out of the end of the canister.

Data Analysis — What does the data tell us? Explain to the students what they will be doing in this lab by going over the lab first. Let the children take turns adding a piece of an Alka Seltzer table to the cup. Any sound that you make will be recorded and could affect your data. To take the tablets, they're fully dissolved in water, where they famously undergo a chemical reaction that produces lots of carbon dioxide bubbles—or fizz. In this science project, you can even measure how long and loudly your tablet fizzes using Google's app. Calculate the average for each of the three water temperatures and record your results in the data table in your lab notebook.
