What is the effect of the mass of candy on the speed and going through a funnel?

• The mass affects the speed of a falling object
• Gravity takes a huge part in mass and falling objects
• The weight/mass plays a huge role in how hard the object falls
• Mass is the only factor used for how fast objects drop
• Items float off on it’s own without gravitational pull
• Gravitational pull helps drop objects and the more pull, the harder and faster it goes down
• The quantity of matter in a body regardless of its volume or any forces acting on it
• The force of the mass depends on where it is.
If the type of candy is changed then the mass of the waterfall will grow because different types of candy have different types of mass, therefore some types will have more mass than others
~ Medium sized cardboard box.
~ Kitchen scale that can measure in grams
~ Cup for scooping the candy. (Hershey Kisses, Skittles, and M and M’s.)
~ Medium sized mixing bowl
~ Metric ruler
~ Lab notebook
~ 5 different granular materials
1. Gather your materials.
2. Cut a hole in one side of the cardboard box. The hole should be wide enough that your plastic funnel can rest in it.
3. Record the characteristics of your granular materials.
4. Use your kitchen scale to measure at least 25(g) of your first granular material.
5. Plug the bottom of the funnel with your hand or with one of the cardboard cut-out pieces from your box. Pour your granular material into the funnel and make sure none is leaking out the bottom.
6. Get your stopwatch ready.
7. Remove your hand from under the funnel and pour the candy in.
8. Watch the funnel closely.
9. Record the mass of the material and the time it took to leave the funnel in the first row of your data table.
10. Repeat steps 5-8 to do at least two more trials with the same material.
11. Repeat steps 5-9 for each of your materials.
12. Record your results.
Trial 1 Trial 2 Trial 3 Avarage
Cho. Rai. 5.67 5.02 3.46 4.67
M & M's 5.02 4.21 4.36 4.71
Skittles 4.8 4.86 4.37 4.51
The graph represents the effect of the size of a funnel on how fast the candy can go down. Some interesting features are how the larger the funnel, the faster it goes down because more candy can fit through the hole. The graph tells that the type of candy does affect how fast the candy goes down the funnel.
In conclusion, the purpose of this experiment was to discover how fast candy falls down three different sized funnels. It was hypothesized that the bigger the funnel, the more candy would go down and the hypothesis was supported. A larger sized funnel had more space for the candy to go down. Three errors may be that the stopwatch didn’t stop at the exact time we wanted it to, the candy was smaller than normal, and the portions of candy varied.
What could be done differently is three different types of candy could have been used. The purpose of this experiment was to find out if larger funnels held more candy. The results can tell us that the larger funnel held more space. Some areas for future research or experimentation were the type of candy could have been different, therefore changing the results.
In conclusion, the purpose of this experiment was to find out if larger funnels meant larger space and it was found that yes, the larger, the more space.
Have you ever wondered why items with more mass fall down faster than items with smaller mass? In this experiment the type of candy will be changed to see if it affects how fast the candy goes down the funnel. Research states that the more mass the candy has, the faster it will go down the funnel due to gravity. The problem in this investigation will be what is the effect of the type of candy on how fast the candy goes down the funnel.
In this experiment we observed the difference of three different types of candy’s speed on how fast it would go down three different types of funnels.
We also observed the difference of candy on how it would actually go down the funnel.
The mass of our candy included Skittles (1.34g), Chocolate Raisins (1.45g), and M & M (1.8g), so in conclusion and newton’s law of physics the Chocolate Raisins will fall faster do to its weight and size.
In conclusion, this experiment was to find how fast candy went down different sized funnels. This helps in real life for construction workers or road builders because they need to know how fast concrete can go down there “funnel” so they can build the sidewalks. For future research, change the three different types of candy to something else and use different sized funnels.
