Data Table 1: Drops of liquid on a penny. Record your data in the table below and calculate the average for each liquid. Values provided in the table were attained from a “test run” of the experiment, and are provided to indicate the range of values you might expect to see during the experiment. Student results will vary.
The zinc (which was already silver) coated the penny. The NaOH dissolved the zinc. (that was what made the water murky) And small pieces of zinc adhered to the penny (coated) It was a physical change because no NEW color was created.
Take out all of the pennies that are tails up. Those pennies have decayed. In the Data Table record the number of pennies you removed (decayed) and the number of pennies left in the box (radioactive). Repeat steps 2 and 3 four times.
In Lab 6, the table that showed colors for different elements said that Fe 2+ [iron(II)] was a greenish color and Fe 3+ [iron(III)] was a yellow color. The yellow color of our dissolved iron(II) sulfate indicates that there is some iron(III) sulfate in the solution.

Students will make salt from water. In this lab ordinary table salt will be used, but in reality the "salt" in salt water consists of various other compounds as will be discussed in the post lab. Water can just take so much salt. Have the students measure about 10 ml of water into a jar. Have the students stir in 1 ml of salt.
Cleaning copper pennies can be a lot of fun for kids! You can turn them from a dull brown to bright and shiny. I decided to turn it into science experiment to test a few different substances and see what works best to clean old brown pennies.
The chart that describes data as points connected by straight lines is called as line graph or line chart. It is useful in displaying the continuous change of data over time. This is an online graph generator/ maker that creates a line chart for the data you enter.
Sep 12, 2019 · The risk of an infinite loop: Compared to a cursor, you don’t have a fixed set of data to loop (i.e. the data returned by the SELECT statement in the cursor declaration), instead when using a WHILE loop you have to define a boundary with an expression that is evaluated to true or false. Building the Test Environment for Cursors and Loops
and blue light is transmitted (Table 1). The amount of red light absorbed is directly proportional to the concentration of the copper (II) ions in the solution as defined by Beer's Law. In this experiment we will measure the absorbance of several copper (II) solutions. Table 1.
