    Geodes form when minerals crystallize from water trickling into holes within rocks. While natural geodes take millions of years to form, you can make your own geodein a few hours or days. Use an eggshell as your “rock” and crystallize salt, sugar, borax, or Epsom salts. Make It an Experiment:Turn this cool project into a science fair experiment by ...

    Explore the principle engineers use to construct buildings to withstand seismic events like earthquakes. Use styrofoam plates as the “ground” and make buildings using craft sticks. Join the craft sticks to each other using mini-marshmallows. Use a sharp pencil to poke holes in the bottom of the plate to insert craft stick supports. These will be th...

    Many color change chemical reaction are clock reactions. What this means is that if you mix the same amounts of chemicals under the same conditions, the color change occurs after the same time interval (like clockwork). The blue bottle reaction and vanishing valentineare excellent clock reactions for 6th grade science projects. Make It an Experimen...

    Many common plastics come from petroleum, but you can make a plastic from milk. Basically, all you do is curdle the milk. Heat 1/2 cup of milk or heavy cream over low to medium heat until it simmers. Stir in lemon juice or vinegar until the mixture starts to thicken. Remove the pot from heat. When the liquid has cooled, rinse the curds with water. ...

    Most leaves look green from chlorophyll, but actually contain several different pigments. In the autumn, plants make less chlorophyll, so you can see the other colors. You can use paper chromatography to see pigmentsin leaves. To do this, grind leaves to break open their cells (a blender works well), place them in a small jar, add just enough alcoh...

    Use a magnet to separate the iron from breakfast cereal so you can actually see it. To do this, pour one cup of crushed cereal into a zipper-lock bag and fill the bag half full of warm water. Shake the bag to mix the contents and allow at least 20 minutes for the flakes to dissolve. Place a strong magnet against the side of the bag and slosh the co...

    Tooth enamel is the mineral hydroxyapatite (hydrated calcium phosphate), while egg shell is calcium carbonate. Egg shell is more porous than tooth enamel, so it stains more quickly. Soak eggs in tea, coffee, soda, and other liquids to determine which ones stain teeth. Common drinks also contain acids in addition to pigments, so some drinks dissolve...

    Learn about oxidation, which includes tarnish, patina, and rust. Explore the cleaning power of common household chemicals. Soak discolored coins in soap, laundry detergent, lemon juice, salt water, soda, ketchup, vinegar, salsa, or any other products you like. After soaking, remove the coins and rinse them to see which ones clean the coins the best...

    Graphite is a form of carbon that conducts electricity. You can draw a line of graphite using a pencil to make a simple circuit. Use a battery with both terminals on top (like a 9V). Turn the battery upside down on the paper and draw heavy pencil lines whether the terminal rest (don’t connect these lines!). Take an LED and bend the wires apart so t...

    Examine the effect of color on perceived taste by coloring different drinks with food coloring and asking subjects to describe their flavor. Make It an Experiment:Compare the flavor of colored and uncolored versions of the same drinks. Start with drinks that don’t have any color so subjects are less likely to guess the drink flavor in advance.

    • Purpose Statement. The purpose statement helps readers understand what you planned to accomplish with your project. Explain the basic reasoning behind the project, why you found the project compelling, and how you think the results of your experiment will be beneficial.
    • Hypothesis. The hypothesis is your rough estimation of what you believe would happen in your experiment. The hypothesis must answer a specific question related to your project.
    • Materials List. The materials list is relatively straightforward. You will simply need to make a list of everything you used to complete your experiment.
    • Procedures. Writing a procedure is necessary so you can perform each section of your experiment consistently. Also, much like the materials list, the procedure section helps another person carry out your experiment if desired.
    • Carbon Sugar Snake. To start off this list, here’s an experiment that focuses on three heat-dependent chemical reactions. By lighting up some baking soda and sugar with a match, you can create a ‘snake’ made from carbon and sugar that continues to grow for up to 20 minutes!
    • Turn Milk into Plastic. With this experiment, you can teach your kids how to make plastic from lots of different materials, even including milk. Once you’ve created the milky plastic, you can even melt and mold the organic casein polymer to make a new product.
    • Which Wheel Works Best? This is a great way to teach kids about acceleration and velocity, and how the material of a wheel can affect the speed and resistance of a skateboard.
    • Baking Soda-Powered Boat. By assembling a plastic bottle with some vinegar, baking soda, and a straw, you can create your very own mini speedboat. The idea behind this experiment is very similar to making a baking soda volcano, as the chemical reaction creates pressure and movement.
  2. May 10, 2019 · One step in this information-sharing is the composition of a project-purpose statement. State the purpose for the experiment. In your first sentence you must clearly explain why you conducted this experiment. Start this sentence with “The purpose of this experiment was to.”. As you finish the sentence, make the importance and applicability ...

  5. Jan 8, 2024 · Engineer the strongest craft stick bridge. Difficulty: Medium / Materials: Basic. This is a classic science activity for the classroom, but it works well for 6th grade science fair projects too. Form a hypothesis about the strongest type of bridge design, then build your own models to test it out.
