How mass affects the swing of a pendulum

In our class we have been doing science experiments for this one we did pendulum science. First there is the normal one then the one were we did painting. Here is mine.

How mass affects the swing of a pendulum

Question:

How long does it take to stop swinging depending on its mass.

Aim/Hypothesis:

We think that objects with more mass will go for longer

Results 

This is how long it took for each of the objects to stop singing.

Bottle 2mins 59 secs . 63

Microphone   2 mins 48 secs . 98

 Blue pen 2 mins 7 secs.40

Highlighter 2 mins 41 secs.19

Conclusion: It is true objects with more mass do swing for longer

Here is my second one

Science Report Pendulum Painting

Aim/Hypothesis: 

Our hypothesis was that it was going to be easy to make a pendulum painting device. Our aim was to make one.

Results:

First we tried using paint but it didn’t work because it was too watery.
So we tried again but the hole was too small. So the paint was to thick to fit
threw the hole or we are just unlucky. We tried to make a bigger hole and
the paint was still to thick. So we tried flour and it didn't go through the
funnel so we gave up.

Conclusion:

In the end our hypothesis was wrong and we didn’t achieve our aim
nothing worked. Maybe next time we could plan more and come up with
a better mix.
