Which Sponge Will Absorb Water

I believe the most appropriate and thorough way to collect the data for this experiment was in the way described in the collection of data. I cooked to each brand according to the directions provided by the manufacturer. By following their directions, that would ensure maximum amount of product.

BEFORE CONDUCTING THE EXPERIMENT - You should already have submitted to your teacher an EXCELLENT Investigation Design that included:

Are pennies better clean or dirty? Clean, of course. Clean pennies are probably used more than dirty pennies, but maybe just clean all the dirty pennies with the products: orange juice, coca cola, and taco sauce and see which one cleans the pennies the best, so then just use those. If any of these products cleans pennies, then coca cola will clean the pennies the best. For independent variable it was the products and the dependent variable is the clean pennies. The control group is the coca cola and the experimental group is orange juice, coca cola, and the taco sauce. For this experiment there was only a few steps to do in order to have clean pennies. After all the materials are ready then pour the products into cups and put at least two pennies in each product. Once the products are in the cups then set timer for 30 minutes and repeat this step for three trials. Collect the weight of the pennies after 30 minutes each time and write it down to see which of the products took off most of the dirt on the penny. Collect all the other data that is needed. This is just one way that cleans pennies but

For my experiment I picked 3 different brands of bubble gums. Hubba Bubba gum, Bubble Yum and Bazooka. After chewing each piece of gum for 2 minutes, one at the time, I blow a bubble as big as I could. Then, my partner (my mom) measured and I write down the results. I repeated the same steps 3 times and results was collected in a data chart (see data chart # 1). Then, the average size of the bubble was calculated by adding each result and divided by 3. The average size of the bubble made from Hubba Bubba Gum was 3.8 cm, Bubble Yum was 3.5 cm and Bazooka was 3.3 cm. As a result of my experiment, I found that Hubba Bubba gum makes the biggest bubble (3.8 cm).

6.) Measure out 50ml of water from the wetland. Place filter paper in a cone shape into the glass funnel then place the funnel above an empty beaker and then pour the 50ml and the see for any precipitate, insects and dirt then record results.

This experiment has a goal of testing a household cleaning theory that dark sodas such as Coca Cola or Pepsi can be used as a cleaning agent and cut through dirt and grease effectively as a cleaner.  For the experiment, the researcher/writer has purchased Pepsi products, Pepsi specifically to use as the cleaning product to test.  The researcher/writer will clean six different types of messes (Food stains of ketchup and mustard on a shirt, kitchen counter grime/grease, bathroom counter soap scum, car windshield and battery corrosion on a car battery and bathroom counter/sink).  Each item will be cleaned with Pepsi and soap and water, with the soap

These steps would be repeated for all three paper towel brands. At the end of the experiment, the paper towel that held the most quarters would be the strongest. Data for experiment still needed to give a conclusion to project.

The results of the experiment for the test of absorbency were that the Sparkle brand proved to be the most absorbent. The average amount of liquid that the Sparkle brand paper towel held was 17.4 mL, which was 4.6 mL more than the Decorator brand held. The Decorator brand only held 12.8 of liquid.

Now label the cups with the sharpie and write down your group’s name and the concentration of solutions: 40%, 20%, 10%, 5%, & 0%.

Then, measure the absorbance at the time that was decided as the optimal in step four.

My independent variable is different kinds of liquids i can test and the liquids i will be testing is soda and salt water but it depends if i have the ingredients i will test i want to see if the things will float. If they both float then i will have to test something else and i might use ice water or lemonade. But their is a 50% chance that it will work but their is a 50% chance it will work but i don't think. I think it will fail cause i

The main issue is to find out the best method that suits the nature of

The materials used during the experiment included three plastic cups, three gummy bears, masking tape, marker, balance, calculator, tray, one plastic spoon, a measurement tray, and a ruler. The three plastic cups were used to hold the tap water, salt water, and sugar water. The masking tape and marker were used to label each cup with the

Measure 500ml of tap water in the 500cm3 beaker, then measure 5g of sodium hydrogen carbonate using the 50cm3 beaker and weight scale and place in the beaker of water, using the glass rod to dissolve it into the mixture.

Materials: Observation 1; 1 cup of water, 2 cups of sugar, 1 glass jar, 1 wooden skewer, 1 plate and 2 clothespins. Observation 2; 1 cup of water, 3 cups of sugar, 1 glass jar, 1 wooden skewer, 1 plate, 5 drops of red food coloring, and one plate.
