THE SCIENTIFIC METHOD

step by step science experiments

  1. How to make a Volcano


Materials:

  • 10 ml of dish soap

  • 100 ml of warm water

  • 400 ml of white vinegar

  • Food coloring

  • Baking soda slurry (fill a cup about ½ with baking soda, then fill the rest of the way with water)

  • Empty 2 liter soda bottle

INSTRUCTIONS:

NOTE: This should be done outside due to the mess.

  1. Combine the vinegar, water, dish soap and 2 drops of food coloring into the empty soda bottle.

  2. Use a spoon to mix the baking soda slurry until it is all a liquid.

  3. Eruption time! … Pour the baking soda slurry into the soda bottle quickly and step back!

How it Works:

A chemical reaction between vinegar and baking soda creates a gas called carbon dioxide. Carbon dioxide is the same type of gas used to make the carbonation in sodas. What happens if you shake up a soda? The gas gets very excited and tries to spread out. There is not enough room in the bottle for the gas to spread out so it leaves through the opening very quickly, causing an eruption!

2. Home Made Play Dough


Materials:

  • 3 cups of flour

  • 1 ½ cups of salt

  • 6 tspn cream of tartar

  • 3 tbspn of oil

  • 3 cups of water

Instructions:


*Junior Scientists must have a responsible adult assistant to help!

  1. Dissolve salt in the water.

  2. Pour all ingredients into a large pot.

  3. Stir constantly over medium heat until a ball forms by pulling away from the sides.

  4. Knead the dough mixture until the texture matches playdough (1-2 minutes).

  5. Store in plastic container. Should last for at least 3 months.

You can even try adding a package of Kool Aid to give the playdough color and a nice scent!

3. lAVA LAMP

Materials:

  • A clean plastic bottle, try to use one with smooth sides

  • Water

  • Vegetable Oil (or you could use Mineral or Baby Oil instead)

  • Fizzing tablets (such as Alka Seltzer)

  • Food Coloring

Instructions:

  1. Fill the bottle up about 1/4th (1 quarter) with water.

  2. Pour the vegetable oil in the bottle until is almost full. You may want to use a measuring cup with a spout or a funnel. You may have to wait a couple of minutes for the oil and water to separate.

  3. Add a few drops of your favorite food coloring. Watch as the color sinks through the oil. Did your drops of color mix with the water immediately or float in between for a few minutes?

  4. Break your fizzy tablet in half and drop part of it into the bottle. Get ready … here come the bubbly blobs!

  5. You can even get a flashlight, turn off the lights and drop in another half tablet. This time shine the flashlight through the lava lamp while the blobs are bubbling!

How it Works:

The oil floats on top of the water because it is less dense or lighter than water. The food coloring has the same density as the water so it sink through the oil and mixes with the water. When you add the tablet it sinks to the bottom then starts to dissolve. As it dissolves it makes gas, carbon dioxide. Gas or air, is lighter than water so it floats to the top. The air bubbles bring some colored water with them to the top. When the air comes out of the colored water blob, the water gets heavy again and sinks. It does this over and over again until the tablet is completely dissolved.

Extra Experiments:

What happens if you put the cap on after dropping the fizzy tablet in? What if you drop a whole tablet in? When it stops bubbling, try sprinkling some salt into your lava lamp. What happens?

4. milk art

Materials:

  • A bowl

  • ½ cup of milk

  • Dish soap

  • Cotton swab

  • Food Coloring, more than one color

  • Pepper (optional)

Instructions:


1. Pour the milk into the bowl. Be careful not to move the bowl, you want the milk as still as possible.

2. Put one drop of each color in different places in the milk.

3. Put just a tiny amount of soap on the end of the cotton swab, then touch it to one of the colors. WOW!

4. Let the experimenting begin!

5. To clean up, just pour the milk down the drain. (Do not drink it)

video tutorial

How it Works:

Milk has fat in it and the food coloring floats on top of the fat. The fat is all connected with bonds. Think of it like the little pieces of fat all holding hands with each other. Dish soaps are used on greasy or oily dishes because it breaks the bonds in fats allowing them to separate. When you add the dish soap to the milk, the fat separates and moves making your magical milk art!

5. snow fluff

Materials:

  • 1 cup corn starch

  • 1 cup shaving cream

  • Food Coloring

INSTRUCTIONS:

  1. Pour the cup of corn starch into a large bowl. Use a spoon to scoop the shaving cream on top of it. Put 5-10 drops of food coloring on top. Stir to mix.

  2. When the mixture looks like grated cheese, use your hands to squish the mixture even more.

  3. Pretty soon the shaving cream and corn starch will form a ball, about the same texture as dough.

  4. If your mixture is really wet and sticky after mixing, it needs a little more corn starch. If it won’t stick together and falls into pieces, add a little more shaving cream.

  5. That’s it! Try sculpting snow angels, snowmen, or make a tiny snow fort!

VIDEO TUTORIAL

How does it work?

The tiny pieces of corn starch get mixed into the shaving cream and suspended in the mixture. Shaving cream is mad of tiny tiny bubbles, and the surface tension on the surface of the bubbles helps ‘float’ the corn starch particles when the two mix.
