Suggestions for Science tomorrow: Find Mrs Joyce A Fabulous Experiment

Science Experiments

Students of 5/6J please find Mrs Joyce a fantabulous science experiment that we can do in tomorrow’s Science Lesson. I am open to ideas that will not cost a lot of money to but supplies.

I will look forward to reading your ideas.

    Making Plastic Milk

    •One cup of milk
    •4 teaspoons of white vinegar
    •A bowl
    •A strainer
    •Adult help

    1.Ask your friendly adult to heat up the milk until it is hot, but not boiling
    2.Now ask the adult to carefully pour the milk into the bowl
    3.Add the vinegar to the milk and stir it up with a spoon for about a minute
    4.Now the fun part, pour the milk through the strainer into the sink – careful it may be hot!
    5.Left behind in the strainer is a mass of lumpy blobs.
    6.When it is cool enough, you can rinse the blobs off in water while you press them together .
    7.Now just mold it into a shape and it will harden in a few days. – Cool!

    Plastic? In milk? Well, sort of. You made a substance called CASEIN. It’s from the latin word meaning “cheese.” CasEin occurs when the protien in the milk meets the acid in the vinegar. The casein in milk does not mix with the acid and so it forms blobs. True plastics, called poymers, are a little different. If you want to make a true plastic and learn more about polymers, try the Homemade Slime experiment. Have fun!

    The project above is a DEMONSTRATION. To make it a true experiment, you can try to answer these questions:

    1. Will more vinegar make more casein?
    2. Will you get the same results with low-fat milk, soy milk?
    3. Do all types of vinegar work?
    4. Will other acids, such as lemon juice and orange juice work?

    A 1 liter plastic bottle
    * Ketchup pack from a fast food restaurant
    * Salt (using Kosher salt helps keep the water from becoming foggy)

    1.Remove any labels from the bottle and fill it all the way to the top with water.
    2.Add a ketchup pack to the bottle.
    3.If the ketchup floats, you’re all set – go to step 4. If the ketchup sinks in the bottle, go to step 5.
    4.For the floating ketchup pack simply screw the cap on the bottle and squeeze the sides of the bottle hard. If the ketchup sinks when you squeeze it, and floats when you release it, congratulations, you’re ready to show it off. If it does not sink when you squeeze it, try a different kind of ketchup pack or try a mustard or soy sauce pack.
    5.If the ketchup pack sinks, add about 3 tablespoons (45 ml) of salt to the bottle. Cap it and shake it up until the salt dissolves. (Kosher salt will keep the water from getting too cloudy, although it will usually clear up over time if using regular table salt.)
    6.Continue adding salt, a few tablespoons at a time until the ketchup is just barely floating to the top of the bottle.
    7.Once it is consistently floating, make sure the bottle is filled to the top with water, and then cap it tightly.
    8.Now squeeze the bottle. The magic ketchup should sink when you squeeze the bottle and float up when you release it. With some practice you can get it to stop in the middle of the bottle.

    This experiment is all about buoyancy and density. Buoyancy describes whether objects float or sink. This usually describes how things float in liquids, but it can also describe how things float or sink in and various gasses.

    Density deals with the amount of mass an object has. Adding salt to the water adjusted the water’s density to get the ketchup to float. Sound complicated? It is, but here’s the basics on the ketchup demo…there is a little bubble inside of the ketchup packet. As we know bubbles float, and the bubble in the ketchup sometimes keeps the heavy packet from sinking. When you squeeze the bottle hard enough, you put pressure on the packet. That causes the bubble to get smaller and the entire packet to become MORE DENSE than the water around it and the packet sinks. When you release the pressure, the bubble expands, making the packet less dense (and more buoyant) and, alas, it floats back up. This demonstration is sometimes known as a CARTESIAN DIVER.

    The project above is a DEMONSTRATION. To make it a true experiment, you can try to answer these questions:

    1. Do different food packs (ketchup, mustard, soy sauce) have the same density?

    2. Does the temperature of the water affect the density of the ketchup packet?

    3. Does the size of the bottle affect how much you have to squeeze to get the packet to sink?

    Make a Crystal Snowflake!

    Learn how to make a snowflake using borax and a few other easy to find household items. Find out how crystals are formed in this fun crystal activity, experiment with food coloring to enhance the look and keep your finished crystal snowflake as a great looking decoration!

    What you’ll need:

    •Wide mouth jar
    •White pipe cleaners
    •Blue food coloring (optional)
    •Boiling water (take care or better still get an adult to help)
    •Small wooden rod or pencil


    Grab a white pipe cleaner and cut it into three sections of the same size. Twist these sections together in the center so that you now have a shape that looks something like a six-sided star. Make sure the points of your shape are even by trimming them to the same length.

    Take the top of one of the pipe cleaners and attach another piece of string to it. Tie the opposite end to your small wooden rod or pencil. You will use this to hang your completed snowflake.

    Carefully fill the jar with boiling water (you might want to get an adult to help with this part).

    For each cup of water add three tablespoons of borax, adding one tablespoon at a time. Stir until the mixture is dissolved but don’t worry if some of the borax settles at the base of the jar.

    Add some of the optional blue food coloring if you’d like to give your snowflake a nice bluish tinge.

    Put the pipe cleaner snowflake into the jar so that the small wooden rod or pencil is resting on the edge of the jar and the snowflake is sitting freely in the borax solution.

    7.Leave the snowflake overnight and when you return in the morning you will find the snowflake covered in crystals! It makes a great decoration that you can show your friends or hang somewhere in your house.

    What’s happening?

    Crystals are made up of molecules arranged in a repeating pattern that extends in all three dimensions. Borax is also known as sodium borate, it is usually found in the form of a white powder made up of colorless crystals that are easily dissolved in water.

    When you add the borax to the boiling water you can dissolve more than you could if you were adding it to cold water, this is because warmer water molecules move around faster and are more spread apart, allowing more room for the borax crystals to dissolve.

    When the solution cools, the water molecules move closer together and it can’t hold as much of the borax solution. Crystals begin to form on top of each other and before you know it you have your completed crystal snow flake!

    A clean 16 ounce plastic soda bottle
    • 1/2 cup 20-volume hydrogen peroxide liquid (20-volume is a 6% solution, ask an adult to get this from a beauty supply store or hair salon)
    •1 Tablespoon (one packet) of dry yeast
    •3 Tablespoons of warm water
    •Liquid dish washing soap
    •Food coloring
    •Small cup
    •Safety goggles

    NOTE: As you can see from the picture, foam will overflow from the bottle, so be sure to do this experiment on a washable surface, or place the bottle on a tray.

    1. Hydrogen peroxide can irritate skin and eyes, so put on those safety goggles and ask an adult to carefully pour the hydrogen peroxide into the bottle.

    2. Add 8 drops of your favorite food coloring into the bottle.

    3. Add about 1 tablespoon of liquid dish soap into the bottle and swish the bottle around a bit to mix it.

    4. In a separate small cup, combine the warm water and the yeast together and mix for about 30 seconds.

    5. Now the adventure starts! Pour the yeast water mixture into the bottle (a funnel helps here) and watch the foaminess begin!

    Foam is awesome! The foam you made is special because each tiny foam bubble is filled with oxygen. The yeast acted as a catalyst (a helper) to remove the oxygen from the hydrogen peroxide. Since it did this very fast, it created lots and lots of bubbles. Did you notice the bottle got warm. Your experiment created a reaction called an Exothermic Reaction – that means it not only created foam, it created heat! The foam produced is just water, soap, and oxygen so you can clean it up with a sponge and pour any extra liquid left in the bottle down the drain.

    This experiment is sometimes called “Elephant’s Toothpaste” because it looks like toothpaste coming out of a tube, but don’t get the foam in your mouth!

    The project above is a DEMONSTRATION. To make it a true experiment, you can try to answer these questions:

    1. Does the amount of yeast change the amount of foam produced?
    2. Does the experiment work as well if you add the dry yeast without mixing it with water?
    3. Does the size of the bottle affect the amount of foam produced?

    Crystal Gardens
    – Three new dry sponges
    – Aluminum pie tin or cake pan
    – Measuring cup
    – 1/4 cup table salt
    – 1/4 cup water
    – 1/4 cup laundry bluing (You can buy bluing at the grocery store under the brand name of Mrs.
    Stewart’s Liquid Bluing.)
    – 2 tablespoons ammonia
    – Mixing bowl
    – Metal spoon
    – Blue and green food coloring

    Process To Make Crystal Garden
    1. Place the sponges into the pie tin.
    2. Mix the salt, water, bluing, and ammonia in the bowl and stir well.
    3. Pour the entire mixture onto the sponges. Spread out the thick stuff over the tops of each sponge
    4. Take you food coloring and drip small drops over the sponges in random patterns.
    5. Leave the pie tin out to sit for a couple days and observe the results.

    The Science Behind Crystal Gardens.
    In a crystal, atoms or molecules join together in a pattern that repeats itself over and over to create a
    certain shape. Crystals grow by adding atoms or molecules to all its sides in the exact same pattern
    as the atoms and molecules that were added before. Now go make a crystal garden with some
