Answer

Brief Explanations:

An observational study just observes and records data without interfering. A controlled experiment manipulates variables. For "How does the daytime temperature affect the formation of dew at night?" and "Why does a rolling ball slow down as it moves?", we mainly observe natural - occurring phenomena. For "How effective is a new toothpaste in reducing cavities?", we can have a control group and an experimental group using the new toothpaste. For "Which is a better absorber of heat, an object painted black or the same object painted white?", we can control the painting of the object. For "Can plants prepare food even in artificial light?", we can set up an experiment with artificial light and a control with natural light.

Answer:

Observational Study: How does the daytime temperature affect the formation of dew at night?, Why does a rolling ball slow down as it moves? Controlled Experiment: How effective is a new toothpaste in reducing cavities?, Which is a better absorber of heat, an object painted black or the same object painted white?, Can plants prepare food even in artificial light?
