How Do Hang Gliders Work? Jennifer Boothroyd Lerner Publishing Group
Who hasn’t dreamed of
flying? Jennifer Boothroyd’s How Do Hang
Gliders Work? fulfills that dream vicariously and answers its title's question. I suspect
the target age is K-3 with its simple sentences and large font, pointing out “The
hang glider is high in the sky!” Equipment vocabulary is listed without complication. This pays off later when the text puts them
into action.
Basic scientific
terms like gravity and lift (including ridge and thermal) are introduced. Concepts such as weight shifting the glider
like a tire swing are brilliantly brought to the kid’s level, using objects kids
are likely to have used or seen.
The appendix contains
a diagrammed illustration, a glossary, an index, further reading (websites and
books), and fun facts like hang gliders have flown for 400 miles. Of course, I would have liked a little more
explanation of lift (I suspect the higher end of the target grade levels could
have handled it), but this book takes a technical subject and allows readers to
feel they can go hang-glide immediately after.
Well done.
