In the ``Science Experiments for Young People'' series, some disappointing experiments on ecosystems, life cycles, pollution, and conservation. Though simple household materials are employed and the authors give plentiful warnings, procedures, observations, and things to try, few of the experiments follow scientific method. Some are merely observations (``What kinds of animals can you find under a log or rock?'') or definitions (``What is Indoor Pollution?''). Multiple variables are not always adequately controlled, and some conclusions are puzzling. In ``Do Plants Use Carbon Dioxide?'' the authors use three samples to test five variables: more samples and controls are needed, and the experiment doesn't prove either that the resulting gas is oxygen or that the gas is a result of photosynthesis. A hot topic, but poorly explored. Index. (Nonfiction. 10-12)

Remarking that ``nothing about the weather is very simple,'' Simon goes on to describe how the sun, atmosphere, earth's rotation, ground cover, altitude, pollution, and other factors influence it; briefly, he also tells how weather balloons gather information. Even for this outstanding author, it's a tough, complex topic, and he's not entirely successful in simplifying it; moreover, the import of the striking uncaptioned color photos here isn't always clear. One passage—``Cumulus clouds sometimes build up into towering masses called cumulus congestus, or swelling cumulus, which may turn into cumulonimbus clouds''—is superimposed on a blue-gray, cloud-covered landscape. But which kind of clouds are these? Another photo, in blue-black and white, shows what might be precipitation in the upper atmosphere, or rain falling on a darkened landscape, or...? Generally competent and certainly attractive, but not Simon's best. (Nonfiction. 10-12)

Miranda’s book counts the monsters gathering at a birthday party, while a simple rhyming text keeps the tally and surveys the action: “Seven starved monsters are licking the dishes./Eight blow out candles and make birthday wishes.” The counting proceeds to ten, then by tens to fifty, then gradually returns to one, which makes the monster’s mother, a purple pin-headed octopus, very happy. The book is surprisingly effective due to Powell’s artwork; the color has texture and density, as if it were poured onto the page, but the real attention-getter is the singularity of every monster attendee. They are highly individual and, therefore, eminently countable. As the numbers start crawling upward, it is both fun and a challenge to try to recognize monsters who have appeared in previous pages, or to attempt to stay focused when counting the swirling or bunched creatures. The story has glints of humor, and in combination with the illustrations is a grand addition to the counting shelf. (Picture book. 3-8)
