Big Bang Balloon Lab Report

Measuring with your fingers helps to make your balloon animal come out in the correct proportions.

11) The gas accumulation in the balloon was measured and recorded at one minute intervals for a total of 10 minutes (qualitative observations were included)

___The helium in the tank must be more dense than the helium in the balloons. ______________________________________________________________________

This problem wasn't solved until the 1920s, when Edwin Hubble devised the first method of extragalactic distance measurement. His technique relied on stars known as Cepheid variables, whose luminosities can be easily determined by measuring their rates of pulsation. Comparing this luminosity with the stars' observed brightness allowed Hubble to estimate the distance to Cepheid stars in such galaxies, affirming their extragalactic location.

The teacher then does a complete demonstration of the process of making the metric tablet. Begin by showing how to mix a ball of clay until it has a pliable

5. Zoom Out by clicking on the green arrow next to the Save button. Click on the Stockroom and then on the Clipboard and select Balloon Experiment N2. Again, set the temperature, pressure, and moles to 298 K, 1.00 atm, and 0.300 moles, respectively. You may have to click on the Units button to change some of the variables to the correct units. Repeat the experiment with this gas labeling the data link ‘Real Gas N2.’

3. Bring the charged balloon close to the paper scraps from Part 2. How does the rubbed balloon

It is easy to flip to the index of an astronomy textbook to discover that, say, the Sun lies 150 million kilometers away from Earth. It is far more difficult (if not impossible), however, to picture this distance in our mind. In this exercise, we will learn to access the often unpalatable distances encountered in astronomy by simply scaling the huge distances to more recognizable, familiar numbers. So long as every distance within the system of interest is scaled by the same

Use a metric ruler to measure the displacement of the tip of the second hand every five

Get a metric ruler and an envelope with metal blocks from your teacher. Write the unknown number from the envelope on the data table.

After we had the balloons with filled with 10mL of vinegar each, we attached them to the baking soda test tubes. After all the components had been situated, we carefully lifted each balloon to pour the vinegar in. We made sure to closely compare which balloons had inflated more than others, and to see if any baking soda was left behind. A good technique to utilize would be to take pictures of the results; a technique that my group could have benefited from should we have used

Gather the following materials-a piece of paper, 11 pieces of Dubble Bubble chewing gum, a pen or pencil, and a mass scale.

The hotter the air became, the more inflated the balloon was. The colder it became the smaller the balloon was. 4) Describe what happens to the marshmallows when the piston is pulled out and pushed in again. What is the gas particle basis for your observations? When the piston was pulled out the marshmallows grew in size, and when it was pushed in the marshmallows shrunk and wrinkled.
