brown with or without pits?

My project is about if guacamole takes longer to brown if the pit is in it. I did an experiment where i put two containers of guacamole in the fridge, one had a pit and one did not. the link for my project is below.]]> 2021-05-18 17:19:46 UTC https://padlet.com/frankelrivera/42p385it2v8on9xw/wish/1536678781 Fire and Water noaglick https://padlet.com/frankelrivera/42p385it2v8on9xw/wish/1536722048 How do water and fire react to each other?

Our project has to do with fire and water. In our slideshow and on our poster board we used the scientific method to determine would fire or water win.

Have you ever wondered if you are cleaner than a dog? Well, if you did  you are in the right place!!!! Our question is are we cleaner than a dog? We  took petri dishes and touched them, then we waited 3 days to see how much bacteria would grow.  

Hypothesis: Our hypothesis is that there will be more bacteria on choco (dog) plates 

Materials:6  petri dishes   3 cotton swabs 2 humans 1 dog. 

Variables. independent  variables species, and body parts 
Dependent variables  growth rate of bacteria 
Controlled variables  petri dishes 

Results: In the end we saw that chocos (dog )dishes had the fastest growth rate and the most on both of her dishes in the end.

Welcome to Cole and Quincys science fair project, today we well be exploring on what ingredient in soda reacts highly to mentos and baking soda? With our hypothesis, question, materials,  variables ,Experiment and data/results shown below.]]> 2021-05-24 17:37:57 UTC https://padlet.com/frankelrivera/42p385it2v8on9xw/wish/1554696238 Video https://padlet.com/frankelrivera/42p385it2v8on9xw/wish/1554737139 This is a video of the end result.

Our question is what ingredient in soda does baking soda and mentos react highly to?.Our materials for this experiment are soda mentos and baking soda. our variables are mentos and baking soda as the independent variable because it doesn't change and soda as the dependent variable. Our procedure is put three mentos and a teaspoon of baking soda into the different sodas. finally our data and results are that baking soda and mentos react highly to sodium and sugar.]]> 2021-05-24 17:52:22 UTC https://padlet.com/frankelrivera/42p385it2v8on9xw/wish/1554756902 frankelrivera https://padlet.com/frankelrivera/42p385it2v8on9xw/wish/1557875863 2021-05-25 14:43:18 UTC https://padlet.com/frankelrivera/42p385it2v8on9xw/wish/1557875863 frankelrivera https://padlet.com/frankelrivera/42p385it2v8on9xw/wish/1557877466 2021-05-25 14:43:42 UTC https://padlet.com/frankelrivera/42p385it2v8on9xw/wish/1557877466 Frequency & Amplitude avagionfriddo https://padlet.com/frankelrivera/42p385it2v8on9xw/wish/1557911158 Will frequency affect the amplitude of waves?
Our hypothesis is if we move the water faster will the waves be taller. Or if we move the water slower will the waves be taller. we tested using a water bin and a paint pallet to move the water. We tested if frequency will affect amplitude and it did.]]> 2021-05-25 14:51:29 UTC https://padlet.com/frankelrivera/42p385it2v8on9xw/wish/1557911158 avagionfriddo https://padlet.com/frankelrivera/42p385it2v8on9xw/wish/1557921000 2021-05-25 14:53:43 UTC https://padlet.com/frankelrivera/42p385it2v8on9xw/wish/1557921000 Coke And Mentos Experiment clarapopescu https://padlet.com/frankelrivera/42p385it2v8on9xw/wish/1557943429 Which soda will react more strongly to mentos?

Our experiment is Coca Cola and mentos mix and they make an explosion. So if coca cola explodes with mentos, does diet coke work better? Our hypothesis is that diet coke will make a bigger explosion. We are basing this off of the fact that diet coke has more chemicals. We made the explosion by first putting 1 mento in diet coke and 1 in normal coke, diet coke went higher and for longer. Our conclusion is that our hypothesis was correct! Diet coke worked better.

Our science fair project is called Element Colors.
Our question is what colors are in the elements lithium, strontium, sodium, calcium, and potassium.

Our materials are elements extract, a spectroscope, sticks, fire from a stove, and water.

in our experiment we put a little stick in water for 2-3 minutes then we dipped the stick in the element we were using. Then we put the stick in the stove fire and used our spectroscope to see the inside color.

Our data is:
Sodium has a orange and yellow flame and looking through the spectroscope it reveals the real color which was purple, green, and red.

For lithium the flame was purple, green, and red also with a hint of yellow and blue. The inside was pink and red.

Potassium was all of the rainbow colors. The flame color was gold, orange and pink.

Strontium was super liney and it was purple, blue, green, and red. The flame color was pink and red.

Calcium was the linyest and had a green stripe, orange stripe, and a red stripe.

These are the colors of lithium, sodium, potassium, strontium, and calcium.
