FAQ
How do I use this periodic table worksheet?
⌄
Begin with the blank table and the history sheet, then move through the family sheets one at a time. Use the crossword, move card game and review quiz for practice, and keep the reference page in student notebooks.
What does this worksheet teach?
⌄
Read how nitrogen, phosphorus, oxygen and sulfur serve living things, then write their ions. The directions on the page read: Read the text and the table. Then answer the questions on page 2. An answer key is included.
Can I use this periodic table worksheet for homeschool or classroom?
⌄
Yes, both. We made it for 7th grade matter, and it works the same at home or at school. At home, a student can work through it alone and then go over it with you, which shows quickly what is solid and what needs another look. In class it works as independent practice, homework or a warm-up, and you can print one copy or a full set.
What is the difference between a group and a period?
⌄
A period is a row and a group is a column. Students use this on the move card game, the clue hunt and the review quiz.
Which periodic table trends do students graph?
⌄
Students graph melting point down group 1, atomic radius across period 2 and down group 1, and melting points across period 3. Each graph is followed by questions that ask for the trend and its reason.
Are there answer keys for the periodic table worksheets?
⌄
22 of the 23 sheets have answer keys. The periodic table reference page is made for notebooks and has no key.
Do the sheets cover how Mendeleev built the table?
⌄
Yes. One sheet places Döbereiner, Newlands, Mendeleev, Moseley and Seaborg on a timeline and asks how close Mendeleev's predictions came.
