Brain Patterns experiments

What to do in this anatomy experiment. Pat the top of your head with one hand At the same time, pat your stomach with your other hand Keep patting your head, but start to rub your stomach in a circle movement Swap over. Now, rub you head while patting your stomach.   What’s happening It is easy for the hands to do the same pattern of movement. but it is hard to do two different movements at the same time.   Why is this? When you repeat the same movement, you get used to moving your hands in then same…

Bubble Snakes experiments

When you blow air through your Bubble Snake bottle, you are creating hundreds of tiny bubbles. As the air wiggles through the cheesecloth or towel, bubbles are continuously being made. The bubbles attach to each other when they come out of the fabric.   This is due to the surface tension of water. Surface tension of water tends to make bubbles unstable and due to this force they don’t last very long. But on adding soap the surface tension is lowered but still the bubbles aren’t very stable due to the force that water exerts on it so to reduce…

How do animals see the world? Experiment

Experiment #1 Cut a piece of card stock paper 28cm (11in) long by 9 cm (3.5 in) wide 2) Cut an arch halfway on the card to fit your nose. 3) Put the card to your face. Your nose must fit in the arch, and the card must touch your forehead. 4) Bend the sides of the card slightly away from your head. 5) Flex the ends of the card so what you see is clearly in focus. 6) What is different about the way you now see things? What’s happening You can see from either side of your head…

Awesome WINDBAG Science Experiment

PROCEDURE Tie a knot in one end of the Windbag, leaving the other end open. Ask a friend how many breaths would it take to fill the bag? Hold the bag horizontal and start. You can fill the bag by holding the mouth of the bag at arm’s length. and blowing once directly into the bag. The entire bag will inflate in one breath.   EXPLANATION The Windbag is a long, narrow plastic bag that is about 8 foot long and about 8 inches wide. The bag can be blown up the old fashion way like Grace tried in the…

Balloon Center of Gravity Experiment

The balloon without the coin is easy to move, but the balloon with the coin is not that easy to move and control.   Why is this? When you toss the balloon with the coin in the air you can’t tell which way it’s going to go. This is because the balloon center of gravity.   The center of Gravity is where the majority of and object weight is located. In the case of the empty balloon it’s leaning towards the mouth and with a ball its in the center.   Because the coin adds more weight to the balloon…

Not the glass with the extraction liquid. – Remove the green stems from the strawberries. – Put Strawberries into the ziplock bag and…

Can you put a Ping Pong ball into a glass? Experiment

RULES No moving the cup No touching the ball or scooping the ball No sucking the straw (You can blow into the straw)   Grace is blowing air into the straw and is flowing out of the funnel at a high velocity. The ping pong ball is placed under the funnel, the low pressure created by the high velocity air going around the ball will keep it in the funnel. Once Grace stops blowing the ball will fall out of the funnel.  

The Paper Helicopter Experiment

Cut along the SOLID lines. Fold along the DASHED lines. Fold flaps C and D inward, then fold the bottom up; this will create a handle of sorts. you can also make your own design like Grace did. Let us know in the comments below how long it took your helicopter to go down.   EXPLANATION As a result, there is less air pressure on top of the wing; this causes suction and makes the wing move up. A helicopter’s rotor blades are wings and create lift. An airplane must fly fast to move enough air over its wings to…

Baking Soda & vinegar exploding bag!

AWESOME! No other words for this experiment. We all know what’s going to happen, but when. If your bored and have nothing to do then this experiment will add some excitement to your afternoon.   What happens inside the bag is a chemical reaction – the baking soda and the vinegar eventually mix (the paper towel buys you some time, as it’s like a fuse) When they do mix, you create an ACID-BASE reaction and the baking soda and vinegar work together to create a gas, (carbon dioxide) The carbon dioxide starts to fill the bag, and keeps filling the…

Static Electricity with soda can Experiment

First start by rubbing the balloon on wool or your hair or your dogs hair.   When you rub the balloon on your hair, tiny parts of the atoms in your hair, called ELECTRONS, collected on the balloon. These electrons have a NEGATIVE charge. Now that the balloon has a negative charge, it is attracted to things that have a POSITIVE charge.   When you bring the negatively charged balloon near the faucet it is attracted to the POSITIVE force of the water. The attraction is strong enough to actually pull the water towards the balloon as it is flowing!…

Electromagnetic Experiments

Use a cloth or gloves, as the battery will get very warm. Grab the ends of the battery with your gloves or cloth and try to pick up some metal objects.   Now the iron nail has become a magnet. This is really awesome.   Because the electricity flowing through the copper wire it passes through the iron nail. This makes it magnetic, Electromagnetic! When I remove the battery it is not magnetic anymore, this is because electricity is not flowing through the copper wire without the battery.  

Electrostatic Toothpick Experiment

Now I blew up a balloon, and rubbed it across my hair (freshly washed hair works best). Now we have a negatively charged the balloon. You can test your balloon by seeing if it will raise the hairs on your arm, if it can then your ready. If not rub the balloon more on your hair. If you don’t want to rub it on your hair, try your dog they love it.   With my balloon negatively charged and bring it closer to the cup….. The toothpick moves. The positively centered toothpick is attracted to the negatively charged balloon, which…

Static Electricity Butterfly Experiment

What makes the butterfly move its wings? When we rubbed the balloon onto our hair, or carpet the electrons were lost from our hair/carpet and gained by the balloon giving it a static charge. When the negatively charged balloon gets close to the positively charged tissue paper they are attracted to each other, and the pull of attraction is so great that the lightweight tissue paper moves toward the balloon.  

ElectroMagnetic Train Experiment

Safety Note: Neodymium magnets are extremely strong and definitely not for kids who put things in their mouths.   What you need: 18 gauge copper wire, AAA Battery, (6) Neodymium Magnets, 5/8 inch electrically pipe & Wire cutters   We put 3 magnets on each end of the train. The magnets need to be placed on the battery with the poles facing opposite directions. Otherwise, the train will not work.   The coils need to be wrapped pretty closely around the train. I wrapped the wire on a 5/8 inch (1.59 cm) electrically pipe. I used 18 gauge copper wire…

Microwave LIGHT BULB experiment

Materials Light bulb Glass Microwave   Safety Precautions: Perform this experiment with only adult supervision. Do not perform this experiment for longer then 15 seconds. Wear safety goggles.   Place a light bulb in a glass filled halfway with water. Place in the center of the microwave and turn on for no more than 15 seconds. Observer   Explanation: The light bulb will light up when the microwave is turned on! This is possible because the tungsten filament within the light bulb is able to absorb the microwave radiation. AS this filament absorbs energy, it becomes so hot that is…

GELATIN STALAGMITES experiment

Procedure Pour a small pile of unflavored gelatin on the tabletop or plate. Rub a balloon in your hair and bring it near the gelatin.   Explanation The particles of gelatin will arrange themselves in columns resembling stalagmites as the charged balloon is brought near. The gelatin particles are normally neutral, but become temporarily polar when brought near the balloon. The negatively charged balloon repels the negative charges and brings the positive charges closer to the surface of the gelatin particles. The polarity is transmitted to the neighboring particles, until you eventually have a long chain of molecules held together…

FUN-FLY-STICK – Static Electricity experiment

The magic force of the FUN FLY STICK is static electricity. It is the same static electricity that you generate when you rub a balloon on your hair or walk across the carpet. IF you touch someone conductive and get shocked, you know that you had static charge.   The FUN FLY STICK is a portable static electricity generator simply by running a rubber belt over two rollers. The semi-conductive cardboard coupled with the much smaller electrical charge generated by the Fun Fly Stick, eliminates risk of being zapped.   IF you love science like I do, and want to…

Opposites Attract Static Electricity Experiment

PROCEDURE 1) Fill plastic tube with small amount of styrofoam balls. 2) Close end of tube 3) Rub the outside of the plastic tube with the styrofoam balls inside with wool, your hair or something to charge it up for about 15 to 30 seconds.   You should start to see the styrofoam balls jump, dance and then stick to the walls of the plastic tube.   EXPLANATION By rubbing the tube we transferring electrons from the wool cloth to the surface of the plastic tube. The electrons now on the surface of the tube are attracted to the protons…

Copper quarters Experiment

Copper quarters – Using some long pliers, take a quarter and insert it into the flame. You’ll want to rotate it every few seconds to heat it evenly. After about 20 seconds it should be glowing red, to avoid overheating it, you’ll want to remove it at this point.   Immediately drop the quarter into a 100 ml (3.3 oz) beaker filled with roughly 60 ml (2 oz) of Heet. It will begin to boil vigorously and then slow down to almost nothing, only to start boiling again in one short burst.   Watching the process again. Watch how quickly…

One minute Ice cold beer

An important part of chilling beer fast is to maximize how much of the can/bottle’s surface area is in contact with the chilling agent, whether it’s ice, water, or cold air.   Salt-water lets you chill a warm beer really fast — much faster than a freezer. Pour cold water, ice, and salt into the cooler to create a salt-water-ice bath.   The ice will cool the water down and the salt will allow the water temperature to drop below 0°C. The beer will then be fully submersed in sub-zero water, maximizing the surface area in contact.
