Science teacher Wiese (Cosmic Science, not reviewed) is back with
40 quick and often intriguing science puzzles and activities to
promote understanding of the human body. Activities are grouped in
body systems: Brain and nervous system; Senses, Digestive;
Respiratory; Circulatory; Muscular, Skeletal, Reproductive and the
Skin. For each section Wiese gives an introduction and a series of
projects and experiments. He lists materials, procedures, provides
an explanation of what happened, and often gives more fun stuff to
do. Most projects and experiments require only a few minutes and
items easily found in the kitchen: straws, plastic soda bottles,
paper plates, ruler, balloons, bread, and scissors. Drawings show
boys and girls having fun with science. Some activities are more
crafts than science: in Blood and Gore, children make a batch of
fake blood, from white corn syrup, corn starch, and soy sauce. The
fake-blood project continues, creating a cocoa and petroleum jelly
scab. Later the author explains the real components of blood.
Sometimes the explanations are less than satisfactory. In Bony
Blocks, he has the reader balance a book on a toilet-paper roll set
on its side and standing on end. This, he explains, shows a hollow
tube is almost as strong as a solid rod. However, whether the roll
is on its side or on its end, it is still a hollow tube. There is a
lot here to engage curious young people. The index was not seen.
