1 cup with string several hex nuts several strings of spaghetti and two desks.
Spaghetti and marbles post lab analysis and refelction.
The independent variable we tested was the number of standard spaghetti strands and the dependent variable we tested was the strength the spaghetti strands could hold before breaking in hex nuts.
Continue until the spaghetti breaks completely in two.
In eighteen minutes teams must build the tallest free standing structure out of 20 sticks of spaghetti one yard of tape one yard of string and one marshmallow.
For every 1 2 added spaghetti strands 6 3 marbles were added to the strength.
Visit the marshmallow challenge website for more information.
The design of the bridge will determine how many marbles can be supported therefore the number of marbles is the dependent variable.
The group hypothesized that if there were more strands of pasta then the spaghetti bridge would be able to hold more mass because spaghetti is able to hold more mass when there are.
Iv spaghetti strands dv strength marbles hex nuts cv the initial setup what you re testing on same size cup marbles hex nuts the placement of the cup on the spaghetti the type of spaghetti we were discussing the difference of the variables.
Answering the question asked in our purpose we discovered that for every strand of spaghetti added 10 5 marbles were added to the measurement of the strength.
Calculate the average mass for each spaghetti pattern and record on your.
In this experiment we will be testing the strength of the spaghetti of strands.
The lab was designed in order for the class to test the relationship between the strength of a spaghetti bridge and the number of strands of pasta used to make it.
Gently place the marbles one by one into the dixie cup.
The marshmallow needs to be on top the marshmallow challenge was developed by tom wujec who has done the activity with hundreds of groups around the world.
When there are 0 strands of spaghetti the strength is 5 marbles.
New paragraph looking at the data analysis we discovered that as the number of spaghetti strands increased the strength measured in marbles also increased linearly.
The strength is 5 marbles rather than 0 marbles because our set up of materials was possibly off on different trials and.
This lab involves students being exposed to identifying independent and dependent variables collecting data and creating and analyzing a graph.
Ask the students to measure and record the value for all of the other variables on the board which must be held constant or controlled.
Strength 6 3 marbles 1 strand spaghetti 5 marbles great.
The purpose of this lab was to determine how many hex nuts it takes to break a bridge made of x standard spaghetti strands.
The control variable was the length of the spaghetti.
Find the total mass of the clip cup and marbles used on each trial and record on your data table.
Repeat steps 5 8 for each group of spaghetti.
