Habits of Science and Periodic Table Study Guide
Habits of Science:
Review your last study guide. All tests are cumulative.
1. What equipment would be used to measure the variables mass, volume, and length? List the units for each instrument as well.
Mass
Volume
Length
Sandy wanted to find out if the color of food would affect food choices. She put food coloring into 4 identical bowls of mashed potatoes. The colors were red, green, yellow and blue. One bowl of mashed potatoes was left as the regular white color. Students were given the choice to choose the bowl of mashed potatoes of their choice. Each day she recorded the choice of 100 different students. She did this for five days.
What was the independent variable in her experiment?
The control group?
The constants?
The dependent variable?
Periodic Table
2. On a separate sheet of paper, draw a rough sketch of the Periodic Table. Show where the metals, metalloids, and nonmetals are. You don’t need to be exact.
3. Below your drawing give a few characteristics of each group.
Write the group names of the following groups on the periodic table. (See questions 3 and 4.)
Group 1 ___________________ , ,
Group 2 ___________________ , ,
Groups 3-12 ___________________ , ,
The stair step __________________ , ,
Group 17 ___________________ , ,
Group 18 ___________________ , ,
Give characteristics (two or three characteristics) that are unique for each family in the previous question.
5. How is the periodic table organized and what does each tell us? (Include the words period, group, atomic number, and protons.)
Columns?
Rows?
Number Order?
Atoms and the Periodic Table
For each of the following elements, use the periodic table to identify the atomic number, symbol, and atomic mass:
Sodium (Na)
Chlorine (Cl)
Carbon ©
Neon (Ne)
13. What particles do objects most likely lose or gain to become electrically charged?
14. What particles are located in the nucleus? And what is the charge of the nucleus—positive, negative, or neutral?
Atoms and Molecules
15. Draw a representation of an atom and a molecule? Explain your drawings.
