Today in Math
Today in math, our teacher have us M&M'S!!!!!! We used the M&m's to convert decimals to fractions, fractions to percents, and percents to decimals.
Today in science class, we did am experiment. We needed a pipette, water, soapy water, a small beaker, and a penny.
My predictions was that the penny will hold more drops of soapy water than regular water.
In the lab I used two different liquids. Soapy water and regular water. Then I got a 7 mL pipette and a penny. I used the pipette to transfer water on to the penny. The goal of the lab was to see how many drops of water could fit on the surface of a penny until it fell over. I did this with both liquids.
My results were very close together. The average was 33 drops for the regular water. The highest amount of drops I got was 35. The second time I used soapy water. The average drops of water were 16.2.
Due to the data I collected, my prediction was proved wrong. I said that the penny would hold more drops of soapy water. But due to the averages I got, the penny held more drops of regular water.
