How do you come up with a science fair idea?

3 Strategies for an Original Science Fair Project

1. STEP 1: Based on observations, ask a question.
2. STEP 2: Predict the answer to the question (we call that prediction a hypothesis)
3. STEP 3: Design an experiment to generate data to test the hypothesis (easier than it sounds)
4. STEP 4: Analyze the data to determine if the prediction should be accepted or rejected.

How do you make hot ice?

Combine baking soda and vinegar to make sodium acetate, or hot ice! It crystalizes instantly when you pour it, allowing you to create a tower of crystals. Since the process of crystallization is exothermic, the “ice” that forms will be hot to the touch. Science is so cool!

How do I make instant ice?

Turn bowl upside down over a towel (to catch the spills) and place a large ice cube on the bowl. Carefully pour the water slowly onto the ice cube. The water will create a column of frozen ice! In about 20 seconds, the water will get too warm for this trick to work.

How do you make water into ice instantly?

1. How to Turn Water Into Ice Instantly.
2. Step 1: Fill your bowl with ice, rock salt, and water bottles.
3. Step 2: Fill the bottom of a plate with water and put in the freezer.
4. Step 3: Put a thermometer in the ice and watch the temperature drop.
5. Step 4: Carefully pull your bottles out of the bowl and make some ice.

How can you instantly freeze water?

Sharply knock a bottle of supercooled liquid water on the table and it instantly turns to slushy ice before your eyes. You put a plastic bottle of soda pop or water in the freezer for a few minutes to get it ice cold.

How do you make ice in 5 seconds?

The following procedure will allow us to prepare us ice within 5 to 10 seconds. Sprinkle some salt in the water. Then remove it after 2 seconds. suddenly you will observe the whole container which contain water will turn ice.

How do you make shaved ice at home?

Make shave ice: Process ice cubes in a food processor, 2 cups at a time, until cubes stop clattering and look like snow, with no lumps. Or, use a shave-ice machine. Add a scoop of vanilla ice cream to each serving dish. Top with shave ice, then drizzle with either syrup plus a drizzle of sweetened condensed milk.

How do you make ice without electricity?

Mix equal parts water and fertilizer in a bucket or a large bowl, till dissolved. Next, carefully place the smaller metal bowl half filled with water in the bucket. (Note: it must be a metal bowl, plastic will not work.) The bowl of water will freeze, though it takes several hours from what I’ve read.

Will boiling water freeze faster than cold water?

Hot water can in fact freeze faster than cold water for a wide range of experimental conditions. This phenomenon is extremely counterintuitive, and surprising even to most scientists, but it is in fact real. The phenomenon that hot water may freeze faster than cold is often called the Mpemba effect.

How cold is boiling water trick?

It’s important that the water be as close to boiling and the outside air be as cold as possible. The effect is less spectacular or won’t work if the water temperature drops below 200 degrees or if the air temperature climbs above -25 degrees.

Does boiled water freeze faster?

If the water is initially hot, cooled water at the bottom is denser than the hot water at the top, so no convection will occur and the bottom part will start freezing while the top is still warm. This effect, combined with the evaporation effect, may make hot water freeze faster than cold water in some cases.

Is the mpemba effect real?

Under our definition of the Mpemba effect, akin to the definition in the ‘original’ paper by Mpemba & Osborne8 (in which they documented “the time for water to start freezing”) we are forced to conclude that the ‘Mpemba effect’ is not a genuine physical effect and is a scientific fallacy.

Who found the mpemba effect?

The effect now known as the Mpemba effect was first noted in the 4th century BC by Aristotle, and many scientists have noted the same phenomenon in the centuries since Aristotle’s time.

Does hot water kill germs?

Hot water kills germs, though it has to be very hot According to WHO, temperatures of 140°F to 150°F are enough to kill most viruses, and boiling water makes it safe from pathogens like bacteria, viruses, and protozoa.

At what temperature does boiling water freeze instantly?

Boiling Water Turns to Snow This is known as the triple point, and temperatures need to reach 0.01°C (32.018°F) for it to happen, Uttal explains. When you boil water, you’re adding energy to water in its liquid state.

What happens if you throw boiling water into freezing air?

“Because they’re so hot, those tiny water droplets start to vaporize. But since cold air can’t hold as much water vapor as warmer air, the water condenses. Extremely cold temperatures quickly freeze the water droplets, which fall as ice crystals,” Nat Geo reports.

What’s the coldest water you can drink?

The answer definitely isn’t 32 degrees Fahrenheit, even if that’s the freezing point of water. If the conditions are right, water can remain liquid all the way down to minus 55 degrees.

At what temperature would you instantly freeze?

We typically freeze to death when our body temperature drops to 70 Degrees(plus or minus a couple degrees). How long that takes will depend on how much time you spend in the cold and your level of fitness. In general if the temperature is below 40 degrees there is a chance of freezing to death.

How long can a human survive at 0 degrees?

Hypothermia can happen in minutes Hypothermia can develop in as little as five minutes in temperatures of minus 50 degrees Fahrenheit if you’re not dressed properly and have exposed skin, especially the scalp, hands, fingers, and face, Glatter explained. At 30 below zero, hypothermia can set in in about 10 minutes.

What’s the hottest temperature humans can survive?

The maximum body temperature a human can survive is 108.14°F. At higher temperatures the body turns into scrambled eggs: proteins are denatured and the brain gets damaged irreparably. Cold water draws out body heat.
