Ruben's Tube

Objectives/Goals  If the smaller the holes on top of the tube would it differ from the size of the flames and the volume? If I drilled the holes 1/2inch from each other, then how about if I do it in a differ measurement will it change any part of the experiment?  If I use a smaller tank of propane verses a bigger tank of propane will it make a difference to the size of flame that will be emitted from the tube? What if I want to measure the wavelengths of the soundwaves is it possible to measure it with the use of an algebraic equation to figure out the solution?  Methods/Materials Ventilation Ducting Brackets x2 Propane Tubing Hose T Connector Hose Splicers x2 Latex Sheets Scrap Wood Drill Hammer Tape Measure Knife or Scissors Silicone Sealant Epoxy Putty Duct Tape Masking Tape Teflon Tape Results  1 The smaller the hole the less gas escapes the tube but there's more pressure inside the tube thus the emitted flame is more defined.The bigger ...

Seeing Through the Haze

Objectives/Goals   My objective was to find out how light of different wavelengths penetrates smoke. The hypotheses that I tested were that light penetration through smoke is independent of the a) type and b) amount of smoke it passes through.  Methods/Materials  Two different types of smoke were obtained by burning canola oil and juniper needles. A beam of white light was passed through the sample of smoke, and the amount of light at different wavelengths transmitted through the smoke was measured with a homemade spectrometer. An attempt was made to control the amount of smoke (high, medium or low density) per sample.  Results  The two different types of smoke did not have the same pattern of light transmission. At high densities (Approx. 20% light transmitted) canola oil smoke allowed more light of blue wavelengths to pass through.  However at lower densities transmission of reds was equal to blue and yellow and green were less f...

Chill Out

Objectives/Goals  To study if distance between warm bodies placed together and then apart affects their cooling rate. Methods/Materials I studied the cooling rate of one warm body with respect to the cooling rate of two bodies and then three bodies touching the maximum surface area. Then I studied if placing the warm bodies at a distance from one another would affect their cooling rate and what that affect would be. Glass bottles of equally warm water were used to simulate the warm body and temperatures of the bottles were taken over time at equal intervals (2-10min.).  MATERIALS LIST   Three glass bottles of exactly the same size and shape; Three laboratory thermometers scaled up to 200°F;  Metal Pot;  Stove Top;  Plastic Wrap;  One Timer;  Measuring cup;  Grid sheet with intervals of one(1) inch;  Towel;  Oven Mitts.  Results  # The triple bottles touching retained the most heat over ti...

The CD Balloon Hovercraft

Purpose My purpose is to see how far a CD balloon hovercraft will go with a push, compared to a push with air under the hovercraft sustaining it. Hypothesis I think that a hovercraft with air sustaining it will go farther with a push rather than pushing a hovercraft with no air sustaining it. Apparatus balloon CD strong glue pop-top  lidruler Method 1) Put the balloon over the pop-top lid. 2) Open the pop-top lid and blow through it, blowing up the balloon, then closing it. 3) Put some strong glue (I used a glue gun) around the bottom rim of the pop-top lid and glue it to the center of the CD, cover the hole. 4) Push opens the pop-top lid, and the hovercraft glide! Observations 1) I placed the hovercraft on a level table and gave it a slight push. The distance was 40 cm. 2) I pushed the hovercraft again, this time with air sustaing the hovercraft. The distance was 77 cm. Conclusion My hypothesis was right. ...

Lick Your Wounds Away

Introduction There are two types of wounds: closed wounds and open wounds. A closed wound is a wound that happens under the skin and may cause internal bleeding. An open wound is a wound where the skin is broken and foreign material can get into the wound. A wound such as this can be a scratch or a cut. An open wound can get infected where as a closed wound cannot. When the skin is broken an open wound is formed. Wounds can sometimes get infected and the infection can get serious if not treated properly. Infections may result in death. Normally, the skin acts like a barrier and will keep bacteria, viruses, and germs from getting into your body. When bacteria enters the body through an open wound, they will start multiplying quickly. A person can get infected as long as the wound stays open. When a wound occurs, a blood clot will develop. The blood clot will then form a scab which will eventually come off once the skin is repaired. This will stop any further bacteria fro...

The Metronome of a Chemical Reaction

Objectives/Goals  The objective of this project was to test the effect of temperature on the rate of a chemical reaction. I thought that reaction rates would increase with increasing temperature. Methods/Materials Sodium Thiosulfate, Potassium Iodide, Potassium Bromate, Hydrochloric Acid, distilled water, and 2-3 drops of soluble starch were mixed to start the chemical reaction.  When the reaction reached a certain point, the solution would turn blue. To compare the speed of the reaction at different temperatures, the time taken to reach the color change was measured with a stopwatch (in seconds).  All of the reactants were cooled or heated to the appropriate temperature before they were mixed to ensure accuracy.  The experiment was conducted at three temperatures: room temperature (19.5 degrees Celsius), in an ice bath (4.5 degrees Celsius), and in a heat bath (30.5 degrees Celsius).  Results  The results of the experi...

The Magic of Metal Corrosion

Objectives/Goals  Analyze the corrosive behavior between metal fully submerged in liquid versus metal partially submerged and determine whether corrosion reacts similarly when using three types of liquid: An acetic acid, a sodium bicarbonate solution, and salt water. I hypothesized that metals fully submerged will have more corrosion and that the metals will react similarly when tested in different liquid solutions, whether partially or fully submerged.  Methods/Materials  Six-inch strips of aluminum, brass, copper, and iron were cut into two-inch pieces and placed in three different types of liquid: An acetic acid consisting of one cup of full strength white vinegar; a sodium bicarbonate solution consisting of two teaspoons of baking soda dissolved in one cup of distilled water; and salt water produced by dissolving one cup of distilled water with 8 grams of sea salt. Each strip was divided into a 3x5mm hand drawn grid to track and measure the rate of corro...

Grow a Gummy Bear

This is a neat and easy science project for younger children. All you need is a package of gummy bears, some small see-through containers, water, and a marker. The time frame for this project can vary depending on how much time your child is given for the project. The project can be done in as little as a week (7 days) or it can be stretched out over a couple of months. Here are the basics: Take the small containers and the marker. Label the containers for the number of days your child is going to do the project. (Day 1, Day 2, Day 3, etc.) I recommend empty baby food jars with lids since the day can be written on the lid. Fill the containers about half full of water – cold or room temperature, not hot. For each day of the project, drop a single gummy bear into one jar and close the lid. I sorted my gummies by color, but this is optional.) Store containers in a cool space so that the water in the container does not get too warm and melt the gummy bear. (I stored the...

Fooling Your Brain with a Mirror

Aim: To prove that what we see is often affected by what we expect to see with the help of the mirror image experiment. Materials required: 1. Mirrors – 2 in number, square in shape, 12 inches (30 cm) a side, could be either made out of plastic or glass. 2. Epoxy glue and duct tapes. 3. Wooden dowels – 2 in number with diameter as 1 inch (2.5 cm) and 12 inches (30 cm) long. Procedure: 1.      Stick the mirrors together by pasting their backs. If you have a glass mirror then for safety, tape their edges using the duct tapes to seal the sharp edges. Take the two wooden dowels and paste them right in the centre of the mirrors vertically. 2.      Hold the dowels with each hand and as you look at one side of the mirror move the hand which is on the other side. What do you actually see? What happens? Your brain expects the image in the mirror to move as it is fooled to believe that the image it sees is actually your othe...

The Mathematics of Sympathetic Vibrations

Objectives/Goals  Which notes on a piano can induce sympathetic vibrations on an open string? Mathematical relationships between test note and open string frequencies will be used to predict which notes cause sympathetic vibrations. I predict the three test notes in my sample that are harmonics of the open string will resonate the longest. Methods/Materials  Materials used were: a piano, a stopwatch, a frequency chart, and a helper. I depressed a piano key, the damper lifted and the string was "open," or free to vibrate. I played all the notes in one octave higher than the open string. My helper timed the durations of the tone coming from the open string. I averaged and graphed the results.  Results  The thirteen test keys in each sample caused the open string to resonate. Seven test keys caused brief resonance; the vibration inside the sound box caused the open strings to produce a tone.  Three test keys produced tones of intermedi...
