A Brief Note On The Independent Research Project

Procedure: Measure the volume, mass, length and temperature of a variety of items. Create dilution of sugar water.

2. Used a test tube clamp to held the test tube and gently heated the tube in a laboratory burner flame for about 30 seconds.

***Repeat steps 2-4 for each of the following: 5 mL of oil and 2 g each of cornstarch, sodium chloride, and sodium bicarbonate.

The independent variable in my experiment is watering my bean plants with different type of liquids. The dependent variable in my experiment is the plants height measured using a centimeter ruler. The control variables in my

The materials that were used to carry out the experiments on the water samples were ten testing kits. We ran 10 tests on all

Next inserting a rubber stopper wit tubing connector into each of the test tubes and into each of the test tubes using a piece of parafilm around the stopper and tubing to fully seal the test tubes. Obtain a 1mL pipette and dip the free end into a tube of colored water and tap the pipette until the water reaches the first marking of the pipette (0.1mL). Then, connect the pipette to the tubing on the rubber stopper, double checking that all tubing connections are secure. After connecting the pipette and tubing together place the pipette horizontally on the ring stand, keeping the pipette leveled. Let it sit for five minutes to equilibrate, this will be used as a zero starting point.

Close the test tube and shake for a moment then leave the test tube back into the water bath. Wait for the data collection to finish. 8. Afterward, dispose of the solution as your instructor has announced. 9.

To start this experiment you would would get the petri dish and put a cross on it then in one quadrant you put a C (control) then you would number the other quadrants

6. Now place the delivery tube that is attached to the bung underneath the 100ml measuring cylinder in the water.

2. Add a chemical scoop of NaCl (sodium chloride) to a quantity of water (about 5 mL) in a test tube. Shakes

Test tubes 1 and 6 were placed in the 10˚C water bath, test tubes 2 and 7 in the 20˚C water bath, test tubes 3 and 8 in the 30˚C water bath, test tubes 4 and 9 in the 40˚C water bath and test tubes 5 and 10 in the 50˚C water bath.

4. Spot the solution on a TLC plate and check with UV light to see

2. Add 100 ml of water and 1.5 grams of detergent powder as surface active agent.
