I think from my research that the 46 year old will have the fastest reaction time

If I increase the amount of salt then the freezing point will lower because the salt will make it colder.

If the type of fruit changes, then the amount of DNA extracted will vary because different fruits, like strawberries, contain more DNA due to the seeds, with each seed contributing its own genetic material in addition to the fruit itself.

If a person listens to music for a certain amount of time then it will affect their heart rate because of the instruments in the genre.

Aarav Hypothesis

If the material of a basketball affects its bounce height, than the rubber ball will bounce highest. It will bounce the highest because, it is the heaviest ball out of all three, and retains the most energy after the ball hits the ground.

If the amount of yeast changes, then the balloons diameter will change because yeast releases carbon dioxide which inflates the balloon, so if the amount of yeast increases the amount of carbon dioxide will increase too, making the balloon grow bigger and bigger.

My hypothesis is, If age effects the average heart rate of a dancer, and the age range changes, then the younger aged Irish dancers heart rate would be higher than the older dancers.

My hypothesis is that after rubbing the sandpaper across the polish they all will change. But the cheap polish will lose most of its surface area. And the expensive and regular polish will only change a bit and will look mostly the same.

Does changing the type of surface on the ground effect how high a ball will bounce.

If the concentration of salt soliution is increased, then I think the size of salt crystals formed after a week will be larger. Sandman R

Vihan's Hypothesis

If PSI is a measurement to measure how much air used to make soccer balls easy to dribble, and a ball is filled with 12.5 PSI, then I think it will travel further than the 8.5 or 16.5 PSI soccer balls because it has a balance between too much and too less air.

I think that the diet coke will work best because their is different ingredients since it is diet which could make it "explode" higher.

Hypothesis

hoodmh2 — 2025-02-24 15:32:49 UTC

I think the basketball will bounce the highest on concrete because it is the hardest.

Hypothesis

knellar — 2025-02-24 15:49:08 UTC

My hypothesis is that if the ELFudge Elfwich Cocoa Vanilla sandwich cookies stay in 150mL of milk for 30 seconds, then they will absorb more compared to the other types of cookies. This is because the website "The Tasting Table" stated that keebler brand cookies are overall very absorbent; It has been shown by multiple studies.

Science/ Hypothesis

colemmc — 2025-02-24 15:49:11 UTC

If the batteries act up on citrus, then the lemon will have the most electricity because it has the most citrus out of the apple and strawberry.

Cora🧪

alletcl — 2025-02-24 15:50:27 UTC

My hypopthesis is that the cheap nail polish will decrease the most in surface area because its ingredients are cheaper and worse quality.But the regular and expensive polishes surface area will change the least. They will stay mostly the same. Because the ingredients are more high quality and long lasting based on research.

Katie Cole New Hypothesis

colekg — 2025-02-24 15:50:37 UTC

If a person listens to music for a certain amount of time, Then it will affect their heart rate because of the instruments in the genre like Guitar, Saxophone, and Violin.

If the concentration of salt solution is increased, then the size of the salt crystal formed after a week of crystalization will be larger.

I forgot my name on my original one - Annabella K.

My hypothesis is that if the ELFudge Elfwich Cocoa Vanilla cookies stay in 150mL of 1% milk for 30 seconds, then they will absorb more compared to the other types of cookies. This is because a website called, "The Tasting Table" stated that the Keebler brand cookies are more absorbent; shown by multiple of their own studies.

Hypothesis

upadhs1 — 2025-02-24 15:54:36 UTC

If the amount of yeast increases in the mixture, then the balloon will grow bigger, I know this because the mixture of sugar, (warm) water and yeast releases carbon dioxide due to a process called fermentation, so the more the yeast, the more the carbon dioxide, the more the carbon dioxide the more bigger the balloon will grow.

Leila Entsuah

entsula — 2025-02-24 15:55:18 UTC

If I double the amount of baking soda then the cookie's surface area will increase because baking soda acts as the leavening agent which causes the cookie to rise or expand giving a greater surface area

According to my research I think the heavier ball is going to bounce the highest because the more force that is pushes to the ground the more force it pushes the ball up.

My hypothesis is, if age effects the average heart rate, and the age changes, then according to my research, the younger aged Irish dancers heart rate would be higher because the heart muscles pump blood less efficiently with time, therefore the older aged Irish dancers heart rate tends to run slower.

goldbgp — 2025-02-24 15:57:59 UTC

I think the diet coke will work best since it is diet it has different ingredients like: sugar substitutes like aspartame which is something that can be used as a sugar substitute which could make the mentos react more.

If salt crystalizes in water when their is a lot of salt then I think that the freezing point will lower with the most amount of salt because the salt will crystalize and make the water colder.

If a gummy bear is placed in water then the gummy bear will swell. This will happen because the gummy bear will absorb or lose water depending on the concentration of solutes in the liquid. Which causes that to be the reaction from the process osmosis.

If the amount of yeast increases, the size of the balloon grows bigger, I know because when mixed, sugar, (warm) water and yeast, releases carbon dioxide due to fermentation. So the more yeast, the more carbon dioxide, the more bigger the balloon.

My hypothesis is that the cheap polish will lose its surface area the most because they have cheap ingredients such as dibutyl phthalate (DBP), toluene, and formaldehyde. Which are bad for your skin and not durable. While the expensive and regular have better ingredients. So they will last longer.
