TTTTTTTT eeeeeeee aaaaaaaa cccccccc hhhhhhhh eeeeeeee rrrrrrrr ssssssss NNNNNNNN oooooooo tttttttt eeeeeeee ssssssss This book features twenty crosswords, each on a different theme of Science. They provide excellent supplements to core learning activities.

The puzzles require students to research the internet or reference books to obtain some clues’ answers. As such, they are ideal to work on in library sessions, make excellent home assignments, and are suitable activities for fast finishers.

Students will enjoy finding answers to the clues. If an answer is already known it can be printed on the crossword directly; if not known, a few key words typed into a computer’s search engine will bring up the solution.

Teachers choosing to use many of the puzzles with one class may ask their students to keep each of the completed two-page puzzles together in one place... perhaps pasted in an activity file or homework book.

Ideas Follow-up:

About a week after every student has completed a crossword give the class a check-up test by asking them the crossword questions. Students write their one-word answers in their books or on a piece of paper. Research Plus!

Under each crossword there is room for the student to write something of interest –over and above the clues’ solutions- about the topic. If read out to the class everyone’s knowledge will be broadened. Incentive:

Award a small prize for the neatest completed crossword with all solutions correct. Create Your Own Science Crossword:

Using the blank crossword at the end of the book your students can create their own Science Crossword Challenge. They can swap these with classmates.
