The purpose for this experiment is to see how long a paper airplane can be in the air. This experiment is a comparison experiment because you compare the average times which each other. The control is the copier paper because it is the paper that we usually use to make paper airplanes out of. The independent variable is the type of paper airplane because the air planes are made out of different types of paper that would affect how long the paper air plane is in the air. The dependent variable is the amount of time the airplane stays in the air. The results to the experiment were that the recycled paper flew the best. Then the copier paper was the second best and the construction paper was last. This is because the construction paper weighs more than the other papers.

The purpose for this experiment is to see how far the rubber band goes with a different stretch length. This experiment is a relationship experiment because you stretch the same rubber band different lengths. The control is 6 cm because that is what we picked. The independent variable is how far the rubber band is stretched because that affects how far it goes. The dependent variable is the distance it goes from start. First, you use the same rubber band. Then, you shoot the rubber band three times in each different stretch length. You record how far the rubber band flies from the starting point and record it in your table. At the end average each distance. First, we first made each plane the same. Then, one person threw each air plane three times. Then we measured from the starting point from where they landed. We took the average of all three trials and put them into a chart. The results are that the 8 cm stretched rubber band went the farthest and then the 6 cm stretched rubber band. Last is 4 cm stretched rubber band is the shortest time.

The effect of weight on ice was the problem that I solved. The solution to the problem was the heaviest weight melted the ice fastest and the lightest weight melted the slowest. I think the experiment went well and I did not have any problems. I felt that the science project wasn't that hard but it wasn't easy. The hard part about it in my opinion was that you get nervous when you present to the parent and visitors. My research was kind of hard because when I searched something up something else would come up and not be what I am looking for.

The career I picked was a physicist teacher. Teach about the scientific method. Spending time with children and a small amount of time planning and meeting.This relates to my ISP because my ISP has to do with chemical properties of ice and water.

Old Refrigerator



New Refrigerator



The 2 refrigerators look the same but they are different. The difference is the ice and water dispenser that has more choices on how you want your ice to be and your water to be. The new refrigerator can preserve foods for weeks while the old refrigerator can only preserve food for a few days. The outside of the new refrigerator looks nicer than the old refrigerator.

//Three Types of Matter:// The first type of matter is a solid. This is how my group did it. We first got the materials. We got a graduated cylinder, triple beam balance, and a rock. First we filled the graduated cylinder was filled with 75 ml of water.The graduating cylinder was filled the measuring tube with 75 ml of water. The rock was dropped into the graduating cylinder. The amount of the water rose was recorded and converted to cubic cm (6 cm3) to get the volume of the rock. The rock was retrieved from the water. The rock was then placed on the triple beam balance and it's mass was recorded (15.6 grams).

The second type of matter is water. This is how my group did it. We first got the materials. The materials are a graduated cylinder, triple beam balance and water. The graduated cylinder was placed on the triple beam balance and it's mass was recorded. The graduated cylinder was then filled with 60 ml of water. The graduated cylinder was then weighed again with the water inside of it. The weight of the empty graduated cylinder taken from the weight of the full graduated cylinder and the final weight was recorded (68.5).

The third type of matter is air. This is how my group did it. We first got the materials. The materials are a balloon and a triple beam balance. To find if air has mass, put a balloon on a triple beam balance while it has not been blown into, and find its mass. Then, find the mass of the balloon after it has been blown into. The difference between these two masses is the mass of the air inside of the blown up balloon. To find if air has volume. The mass of the balloon before it was blown into was 2.9 grams, and its new mass was 3.0 grams. Therefore, the mass of the air inside of the balloon is 0.1 grams. The volume is 750 ml.

Wiki Entry 5

Table salt is used in food, and beverages. Some salt can be in different colors. The chemical formula for table salt is NaCI that means Sodium Chloride. There are more types of salts with a different symbols. A salt is made when an acid and base are combined to form a compound. A crystal is made by an arrangement of atoms. Salt is a compound because there are 2 different atoms making the compound so it is a compound. Other types of salts beside table salt are sea salt, organic salt, and sour salt. But some of the salts are poi sonous to feel, touch, or smell.




 * MATERIALS AND METHOD **
 * Hot plate
 * Two sets of goggles
 * Sand and salt mixture in 20 mL beaker
 * 2 250 mL beakers
 * 1 600 mL beaker
 * Filter
 * Rubber Band
 * Rubber Tongs
 * Triple beam balance
 * 1 scoopula
 * 200 mL water

A filter was set up by attaching a coffee filter to a 600 mL beaker with a rubber band. The sand/salt mixture was then poured into the filter. 200 mL of water was then slowly poured into the filter. This allowed the salt to dissolve and flow through the filter into the 600 mL beaker with the water, and kept the sand above the filter. The salt water was poured into the 250 mL beaker and the coffee filter with sand was inserted into another 250 mL beaker and allowed to air dry over the weekend. Boiling the water out of the wet sand would have also worked. The beaker with salt water was put onto a hot plate with rubber tongs and the hot plate was turned to 200 degrees Celsius. The beaker was left to boil for about 40 minutes. The beaker was then removed using the rubber tongs. When the water boiled off only salt was left inside the beaker. When dried, the sand was poured and scraped from the filter using a scoopula into a 250 mL beaker. The mass of the salt and the beaker was found with the triple beam balance. The beaker of salt was rinsed thoroughly and dried. The mass of the beaker was found and subtracted from the mass of the beaker. The same was done for the sand.
