🥪 The Soggy Sandwich Dilemma

The script introduces a relatable problem of a soggy sandwich and leads into a discussion of the scientific method as a means to solve everyday issues. The protagonist observes a consistent issue with their peanut butter and jelly sandwich being soggy, particularly on the jelly side, and decides to investigate the cause. The scientific method is outlined as a process involving observation, questioning, research, hypothesis formation, experimentation, data analysis, conclusion drawing, and result communication. The protagonist applies these steps to their sandwich problem, initially hypothesizing that the bag causes the soggy condition, which is tested and found to be incorrect. Further research leads to a new hypothesis about the sandwich's assembly method, which upon testing, proves successful in preventing sogginess.

Keywords

💡Scientific Method

The scientific method is a systematic approach to investigating and understanding phenomena through observation, hypothesis formation, experimentation, and analysis. In the video, it is the core process used to address the everyday problem of a soggy sandwich. The method guides the protagonist through making observations, asking questions, conducting research, forming hypotheses, testing them, and drawing conclusions.

💡Observation

Observation is the first step in the scientific method where one notes and describes phenomena without influencing the system. In the video, the observation is the soggy sandwich, specifically the soggy area on the jelly side, which prompts the question of why the sandwich becomes soggy.

💡Hypothesis

A hypothesis is a proposed explanation for an observation, which can be tested. In the script, the protagonist initially hypothesizes that the sandwich becomes soggy due to being in a bag, and later hypothesizes that using peanut butter as a barrier will prevent sogginess.

💡Experiment

An experiment is a controlled procedure carried out to test the validity of a hypothesis. In the narrative, the protagonist conducts experiments by packing the sandwich in a container and then by using peanut butter as a barrier, to test the hypotheses regarding the cause of the soggy sandwich.

💡Data Analysis

Data analysis involves examining the results of an experiment to draw conclusions. The protagonist analyzes the results of their experiments with the sandwich to determine whether the hypothesis was correct or if a new hypothesis needs to be formed.

💡Conclusion

A conclusion is the final judgment or inference drawn from the experiment. In the video, the conclusion is that peanut butter acts as a barrier to prevent the bread from becoming soggy due to the jelly.

💡Container

A container is a receptacle used to hold something. In the context of the video, the protagonist uses a container as part of the experiment to test if the packaging of the sandwich affects its soggy condition.

💡Peanut Butter and Jelly Sandwich

A peanut butter and jelly sandwich is a common food item consisting of peanut butter and jelly spread between slices of bread. It is the subject of the video, serving as the basis for the scientific method application to solve the problem of sogginess.

💡Soggy

Soggy refers to something that is wet and soft, having absorbed liquid. In the video, the term is used to describe the undesired state of the sandwich, which is the central issue that the scientific method aims to address.

💡Barrier

A barrier is something that prevents or inhibits movement or access. In the context of the video, the protagonist discovers that peanut butter serves as a barrier between the bread and the jelly, preventing the bread from becoming soggy.

💡Research

Research is the systematic investigation and study of materials and sources to establish facts and reach new conclusions. In the video, the protagonist conducts research by asking friends and reading online to inform their hypothesis about the soggy sandwich.

💡Kindness

Kindness is the quality of being friendly, generous, and considerate. While not directly related to the scientific method, the video ends with a message about kindness, suggesting that positive actions can have a multiplying effect on others, which is a broader theme of community and interpersonal relationships.

Transcripts

you sit down next to your friend in the

cafeteria to have yourself a

sophisticated meal consisting of an

apple a slice of cheese and a peanut

butter and jelly sandwich upon taking

your sandwich out of its bag You observe

that once again it is soggy this is the

third day in a row you have opened your

bag to find a sad and Soggy Sandwich

the other days with no more than a

little sigh you resign yourself to your

fate and ate your sandwich today however

you have had enough of soggy sandwiches

you are determined to get to the bottom

of this problem

welcome to moomoomath in science today

we will be talking about the scientific

method we will cover the definition the

steps and a real life example of this

helpful process

the scientific method is a process of

experimentation that is used to explore

observations and answer questions it is

a very helpful process that can help us

find practical solutions to Everyday

problems or help scientists ensure that

the conclusions they draw are accurate

and not based on false assumptions

the steps of the scientific method are

as follows make an observation and ask a

question

conduct research form a hypothesis test

the hypothesis with an experiment

analyze your data and draw a conclusion

communicate your results

returning to the case of the Soggy

Sandwich you have completed the first

two steps of the scientific method you

made an observation that your sandwich

was soggy and specifically that the

sandwich was only soggy on the jelly

site you also asked a question why is my

sandwich soggy you then decide to

conduct research research can take many

forms such as trusted scientific

journals online resources conversations

with friends books and articles you

start by asking your friends who also

eat peanut butter and jelly sandwiches

and also go online and discover that

most people prefer their PB and J in a

solid container you form a hypothesis

which is a proposed explanation that

serves as a starting point for further

investigation you hypothesize that bread

gets soggy in bags but with not in a

container you make a hypothesis if I

pack my sandwich in a container then it

will not get soggy so the next morning

you test your hypothesis you make your

sandwich the same way you always do but

you pack your sandwich in a container

instead of a bag hoping this will serve

as a soggy sandwich problem

when you take your sandwich out at lunch

you are dismayed to find that your

sandwich is still wet you think for a

while and conclude that the way your

sandwich was packed was not the problem

after additional research you propose a

new hypothesis

if I put peanut butter on both sides of

the bread with jelly in the middle then

my sandwich will not get soggy

at lunchtime you open your sandwich and

discover that your hypothesis held true

the peanut butter acted as a barrier

between the jelly and the bread which

caused the sandwich to not become soggy

let's review the steps of the scientific

method as it relates to our example

observation you made the observation

that your sandwich was wet on the jelly

side and you asked the question why is

my sandwich soggy research you as

friends about their sandwiches and

conducted read articles online

you formed a hypothesis in fact you made

two hypotheses the first was that the

bag made your sandwich soggy while a

container would not this hypothesis was

not supported by the result of the

experiment so you made a second

hypothesis that the sandwich making

method determines whether the bread gets

wet or stays dries and that jelly soaks

the bread you tested the hypothesis you

conducted experiments to test your

predictions in a true scientific

experiment you would repeat the

experiment many times to make sure that

your results are accurate

you formed a conclusion you concluded

from running the experiment and

observations that peanut butter acts as

a barrier and prevents the jelly from

making the sandwich soggy

if it was not supported you would need

to repeat the process by forming a new

hypothesis and running new experiments

and finally you can communicate your

results to others

thanks for watching and remember

kindness multiplies kindness
