Activity: Dancing Spaghetti

In this activity you will preform a simple experiment creating "dancing spagetti", and you will be making some observations and drawing some inferences about the spagetti. You will be required to sumbit this as a lab report. Details are outlined below.

Materials

1 glass mixing bowl / glass container (500 mL capacity)

3 tsp sodium hydrogen carbonate (baking soda)

4 to 5 tsp vinegar

10-2 cm peices of vermicelli.

Analysis

1. Create a data table to record your observations. Make a seperate colum for your inferences made while performing this experiment.

2. Suppose you weighed three strands of spaghetti, at 2.34g, 2.00g, and 1.976g. What is the average weight on the spagetti? State your answer to the currect number of significant digits.

3. a) Explain what you was making the spagetti dance

b) is your answer to part a) an observation or an inference?

Your resport should including the following:

Title page, purpose statment , hypothesis, materials, apparatus, procedure/Method, observations, analysis, discussion and conculsion

Explanation / Answer

2. add all numbers and divide by 3

ans. 2.11 (after rounding off)

3.

molecules of co2 produced on acid base reaction of baking soda and vinegar stick to suface of noodles that is porus and lift it through the liquid water making it look as if it is dancing.

As more bubbles add to the noodles, the density of the noodles decreases

This experiment shows that an increase in volume while almost same mass will decrease the density.

Thus the dancing effect. once it reaches the top the bubbles burst and the noodles sink again
