Materials: 5 ft length of schedule 40 PVC pipe 10 inch length 3/4 inch wooden dowel 1 container of potassium nitrate based stump remover 1 bag of bentonite clay based kitty litter 1 bag of powdered sugar 1 roll duct tape Model rocket igniters or fuse 7/32 drill bit Hypothesis: The best ratio for potassium nitrate to powdered sugar is 1 to 3 because Grant Thompson who has experimented with the best ratio of powdered sugar to potassium nitrate has stated that “the 1 to 3 ratio is best for creating the most amount of thrust from your rocket.” This paired with a rounded fin design will get the most distance from our rocket. The rounded fin design will block less air and stabilize the rocket. Purpose: We are doing this this experiment to …show more content…
Cut down the dowel to six inches and mark it at 1-7/16 inches, 2-1/4 inches, and 3 inches. Create three different mixtures of potassium nitrate and powdered sugar; one that is three parts potassium nitrate to one part powdered sugar, one that is two parts potassium nitrate to two parts powdered sugar, and three parts powdered sugar to one part potassium nitrate. Each part is 25 grams. Take the bentonite clay and grind it in a blender until it is at a powdery consistency. Fill a pvc section with one tablespoon of clay (make sure the pvc is on a flat surface). Take the wooden dowel and put it inside the pvc section. Hit the dowel with a mallet 5-10 times until the clay forms a strong plug at the end of the pvc. Pour a mix into a length until it reaches the top of the pvc. slowly push the dowel until it stops allowing you to stick it in farther. The mix will compact. Pour out some of the mix if it goes higher than the second mark on the dowel. If it is below the mark add more white mix until it reaches the second mark on the dowel. Fill the other end with clay powder until you reach the third mark on your dowel. Make hole with a 7\32 drill bit until you reach the white powder at the other
Step4: Put flour on a surface and roll the dough until its ¼ in thickness.
3.) Divide your 30g of white substance into the 4 test tubes evenly. You should put 7.5g into each test tube along with the water.
1) Measure out 200cm3 of water using a measuring cylinder and use a small amount of this to make a paste with 2g of soluble starch.
* Amount of sugar solution in each test tube. * The potatoes have to have the same mass.
Use the stirring rod to dissolve the borax powder in the ‘Borax Solution’ container. Add 3 drops of food
Put half a cup of soil in each of the cups. Pat down to even.
Prepare silica gel column. Add 6 g of silica gel in 20 mL of hexane to make a slurry. Block column with small piece of glass wool, add 5 mL of hexane and then add the silica slurry up to the 10 cm mark.
...how clay holds water. But we were unable to complete this test due to time constraints.
3rd create wells: put a comb template in middle of the tray; wait until the mixture becomes solid. After,
Heat the agarose solution in a microwave to dissolve the powder. Stop the microwave every 10-15 seconds to stir the solution.
Place the dry ingredients in a bowl and then mix them all slowly with the whisk.
0.1M HCl, 10 mL of 0.1N KMnO4, 0.2 g. KI, 5 mL of alcohol, and 5 mL of
To begin, get one of your bowls and your mixing utensil. Then, in your bowl, measure 1 cup of warm water, and pour it in. You can either warm it up in your microwave or set your faucet to the warm setting. Next, measure 1 teaspoon of Borax powder and pour it into the warm water. Be careful during this stage because Borax is a dangerous chemical; I definitely recommend adult supervision. Once, you pour in the Borax, mix until it is dissolved. Then put the mixture aside, as the next step awaits you.

Start by filling a pot with water about 80% full, now add both the black tea and sage powder. Depending on the tea you are
