As Fundamental Forces Go, Gravity Is Pretty Weak. It Can Easily Be Overcome By Air Pressure, As This

Using a series of sensors, Dua’s bot detects when a person is about to run into something and beeps to them. The project took her a total of four days to build. Her prize is every Marvel fan’s dream.

Materials: 1. 3 white carnations 2. Scissors 3. Food coloring 4. 3 small cups 5. Water

Steps: 1. First, get the 3 small cups and add ¾ of the cup with water. 2. Next, in each cup at 8 drops of food coloring of your choice. (Make sure to pour different colors for in each cup to create more multi colorful flowers) 3. Then, snip the last centimeter of the carnations’ stem and place each flower in the colored water. 4. Finally, wait for 2-4 days to see the results.

Lesson: Transpiration is when plants draw water up through its stem, and , thus, the water evaporates from the leaves’ stomata. As the water evaporates, it creates pressure that brings more water into the plant. Since the water had color, it made the flowers become that color.

Materials: 1.jelly crystals 2.small cups 3.iron filings 4.calcium chloride 5.zip lock bag 6.water 7.adult Steps: 1.First, Fill one cup with 9 ounces of water 2. Next add a scoop of jelly crystals to the water and wait until the crystals are fully grown. ( The crystals are done growing when there is no more water in the cup) 3. Then add 4 tablespoons of the full-grown jelly crystals to a Ziploc bag 4. Next add 1 tablespoon of iron filings to the bag 5. Then, add a one and a half tablespoons of calcium chloride 6.next, mix everything in the bag by squishing the bag with your fingers 7.then, when everything is mixed, seal the bag 8.finally, squish and squeeze the bag to feel the heat coming out from it Lesson: When the water and Iron is contacted with air, rust is made with a byproduct of heat. Calcium chloride and water produces an exothermic reaction which starts the oxidation of the iron.

That is what it looks like it you try to burn biscuits straight out of the packet.

This is what it looks like if you try to burn biscuits after you soak them in liquid oxygen:

Adding liquid oxygen means that the biscuits (the fuel in this reaction) can burn to their full potential. When you just burn them in air, there isn’t enough oxygen (one side of the fire triangle of heat, oxygen and fuel), and that limits the reaction.

Materials: 1. Water 2. A clear plastic bottle 3. Vegetable oil 4. Food coloring 5. Alka- Seltzer Steps: 1. First, pour water into into the plastic bottle until it's one quarter full 2. Next, pour vegetable oil until the bottle is nearly full. 3. Then, wait until the oil and water have separated. 4. Next, add 12 drops of any food coloring of your choice into the bottle. 5. Then, watch as the food coloring falls through the oil and mixes with the water. 6. Finally, cut a Alka-Seltzer tablet into 6 smaller pieces and drop one of them into the bottle. Lesson: Oil and water do not mix, so the oil stays on top because it has lower density than water. The piece of Alka-Seltzer tablet releases carbon dioxide gas that rises and takes the colored water to the top. The gas escapes and, thus, the colored water falls down. Alka-Seltzer fizzes because it contains citric acid and baking soda, which are reactive with water creating sodium citric acid and carbon dioxide.
