FAQ

What does this worksheet teach?
⌄
Read why two rows print below the table, then mark where they belong in periods 6 and 7 on a diagram. The directions on the page read: Read the text. Circle the letter for questions 1 and 2. Then go on to 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.
