Two Types of Experiments Extension __Experiment Write-up__ For the ___ experiments write a paragraph that includes the following: Results of the experiment The purpose of this paper airplane experiment is to see which model of paper airplane flies the best. This was a comparison experiment because there is only one set of numbers and you are comparing things, in this case the paper airplane models. The control in this experiment is the standard model, and the independent variable is the model of airplane that we are testing. The dependent variable is how far the plane flies. To conduct this experiment we first made three models of paper airplanes, the Dart, the Standard Model, and the Arrow. Then we laid out four meter sticks on the ground and we flew the airplanes, measuring how far they flew in centimeters. The Arrow flew the best, at a travelling distance average of 780.5 cm, with the Arrow following behind at 611 cm. The standard model, to our surprise, came last, flying only 560 cm on average. The purpose of the rubber band experiment was so that we could see how the thickness of the rubber bands would change how far the rubber band flew. This is a relationship experiment, because we are testing if the width of the rubber band changes how far it flies. ISP Reflection 1. How do stick-em ball stick onto the whiteboard with different substances? (water, oil, and sprite) 2. I found that None sticks best, water works second best, sprite works third best, and oil works the worst. 3. I feel that my experiment went smoothly, and it was good. I could do things to improve this experiment and extend it. 4. I thought that it was really fun, and I want to do this again! ISP Job Reflection Physics teacher relates to my ISP experiment because I can teach forces (suction cups and vacuums!) and how they work. (among other things) and explain to a student how physics is related to their favorite sport. Someone in this career teaches physics. A typical day on the job would be to assign homework, and teach physics. My Model before research I found that there was more inside the vacuum than outside of them. (I took my robot vacuum apart.) There is a motor for five things, a the fan, the wheels (3), and the brush. The batteries in the vacuum are rechargeable. After research (and taking apart the vacuum!) T3 Wiki Entry 4 Review the activity in the “Atomic Nature of Matter” where you proved a rock, water and air are matter. Then, in your Science 6 Wiki, underneath your past entries, summarize the materials & method and results & discussion for each experiment you did. Proving a Rock, Water and Air are Matter. Rock DEFINE THE PROBLEM Is rock matter? MATERIALS & METHOD The mass of the tube will be measured, then the rock was dropped in. Then the tube with the rock will be measured on the balance beam, and the weight subtracted from the empty tube to find the rock's mass. RESULTS & DISCUSSION The tube's mass was 96.25 grams, and the mass of the tube and the rock was 109.5. the mass of the rock was 13.25 grams. Water DEFINE THE PROBLEM We will prove that water is matter by finding its volume and mass. MATERIALS & METHOD To find the volume we will fill a tube with water and measure how much there is. To find the mass we will empty the tube and put it on the triple beam balance. Then we will fill it with 50 ml of water and measure. RESULTS & DISCUSSION The tube had a mass of 96.2 and the tube with 50 ml of water had a mass of 145.2. The fact that the tube was filled with water also proved that it had mass (with the amount that we filled the tube up with, 50 ml) and 145.2-96.2=49 so the water also has mass. Air DEFINE THE PROBLEM We need to prove that air is matter by measuring its mass and volume. MATERIALS & METHOD The balloon was placed on the triple beam balance and weighed for its mass when it was not blown up. It was then blown up and weighed to find the mass. To find the volume, we used cubes (equal to 1 cubic centimeter) to estimate. RESULTS & DISCUSSION When the balloon wasn't blown up it weighed 2.4 g. When it was blown up it weighed 2.7 g. The balloon has a volume of 340.0 cubic centimeters. T3 Wiki Entry 5 Third Trimester Matter Wiki Entry 5 For this Wiki entry you will be researching about table salt and also including a picture of a model you have made about table salt. First, research the following: 1. What is table salt’s chemical formula? Table salt's chemical formula is NaCl. (Sodium Chloride) 2. What makes something a __salt__? Salt is any of a class of compounds formed by the replacement of one or more hydrogen atoms of an acid with elements or groups. 3. What is a __crystal__? Crystals are solids that form by a regular repeated pattern of molecules connecting together. In some solids, the arrangements of the building blocks (atoms and molecules) can be random or very different throughout the material. In crystals, however, a collections of atoms called the Unit Cell is repeated in exactly the same arrangement over and over throughout the entire material. 4. Why is salt considered a compound? Salt is considered a compound because it is composed of one atom of sodium bonded to one atom of chlorine. 5. What other types of salt are there besides table salt? There is alkali salt, sea salt, bamboo salt, artisan salt, Hawaiian sea salt (Which is red volcanic salt from Hawaii)…..

This is the salt crystal that we made. The pink is the chlorine, and the white is the salt. This model was made with toothpicks and colored marshmallows.

T3 Wiki Entry 6: The Separation Challenge We filtered the dissolved salt and the sand with a coffee filter and the salt water went into the beaker, and the and stayed in the filter. The water from the sand was left to evaporate. The salt water was put onto the burner and turned on to evaporate the water from the salt. Then the beakers and the salt in the beaker with the sand in the beakers were weighed, and the weight of the beakers were subtracted from the salt in the beaker and the sand in the beaker. The results were this: Salt=4.7 g Sand=2.4g
