Product Description
This is a great activity or sub plan for Valentine's Day! Science articles make great secondary science sub plans, but finding reliable and interesting articles on the internet or in periodicals is very time consuming. Formatting online articles to fit a printed page can also be challenging and can often waste time and paper. Worst of all, it's often difficult to find articles that will engage your students. This is where this article resource comes in! Each science reading article is 1 and 1/3rd pages of reading text with 2/3rd pages of questions. In total, only two pages to print (one page double-sided) for each student.

Pay only $1.99 for this article when you purchase it in the 50 Science Reading Articles MEGA Bundle - Saving you over 40%.

ARTICLE SUMMARY: In this particular article, students will learn about the three scientifically recognized components of love: sex drive (libido), attraction and attachment.
