Will the balloon racer go farther with or without weight?


Hypothesis

If I add various weight to the middle of the balloon racer, then it will move farther than a car without weight.

Problem

Will the balloon racer go farther with or without weight?

The following is the procedure used to make my car:

Materials for Balloon Car Racer:

  • Piece of cardboard
  • 1 rubber band
  • 1 balloon
  • 4 wheels
  • 2 non-flexible straws
  • 1 flexible straw
  • Tape


Step 1:  Cut a piece of cardboard measuring 8” x 6”.  Decide which side is going to be the top and which one is the bottom.

Step 2:  On the bottom side of the cardboard, place two straws (without a flexible center) about 1” from the front and back of the cardboard.

Step 3:  Insert a dowel rod, smaller than the straw, inside the straw.  This will be the axle rod of the car.

Step 4:  Place four wheels (I used wooden, premade wheels), on the ends of the dowel rod.

Step 5:  Tape ends of dowel rod so wheel won’t fall off.

Step 6:  Take a straw with a flexible middle, bend it in half where the flexible part is, and cut two ends, the same length, making a piece about 5” inches long.

Step 7:  Cover the flexible piece of straw with a balloon.  You want to have about 1 ½” of the straw inside the balloon neck.

Step 8:  Secure the balloon on the straw with a rubber band.

Step 9:  Blow into the balloon to make sure there is no air leaking out.

Step 10:  Position straw with the attached balloon, to the bottom of the racer.  The straw needs to be sticking out about 1½’ from the edge of the cardboard.

Step 11:  Flip the car over and you are ready for a test run.

Procedure/Experiment

Materials for experiment:

  • 1 set of lungs
  • 1 balloon car racer
  • 1 tape measure
  • 3 pennies, nickels, dimes and quarters


Step 1:  Decide to use kitchen floor to run experiment.

Step 2:  Draw three circles on the top and in the middle of the balloon racer.

Step 3:  Tape three pennies on top of each circle.

Step 4:  Blow three puffs of air into the balloon.

Step 5:  Pinch the balloon closed with fingers.

Step 6:  Place racer on starting line on the kitchen floor.

Step 7:  Let go of the balloon.

Step 8:  Measure distance from starting line to finish line with tape measure.

Step 9:  Remove pennies from the racer and replace with the next set of coins.

Step 10:  Repeat experiment with three nickels.

Step 11:  Repeat experiment with three dimes.

Step 12:  Repeat experiment with three quarters.

Results

The car, when no weight was added to it, went further than any of the times when weight was added to the car.  The car, when the three dimes were added, went the second farthest.  The car, when the three nickels were placed on it, went third farthest, followed by the three quarters then the three pennies.

No weight added to the car:
Three dimes:
1.     70 ¾”
2.     92”
3.     108 ¾”
1.     62”
2.     62 ¼”
3.     67 ¾”
Three pennies:
Three quarters:
1.     47”
2.     40 ½”
3.     40 ½’
1.     51 ½”
2.     44”
3.     47”
Three nickels:

1.     48 ½”
2.     54”
3.     51”

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...
