The death toll from the Indian Ocean tsunami of Boxing Day, 2004 was nearly 300,000, so this will be at the top of most people's lists.
Huge floods in China in 1887, 1931 and 1938 killed at least half a million people each time, with some estimates of up to 4 million for the 1931 one.
The volcanic eruption of Mont Pelee on Martinique in 1902 killed nearly 30,000 people. But nearly 40,000 died when Krakatoa erupted in 1883, and over 90,000 in another Indonesian eruption in 1815.
In 1908, an earthquake in Messina, Italy killed about 70,000. In the 1920's there were three separate earthquakes in China and Japan which killed about 200,000 each. A 1970 one in Peru killed 65,000, and another Chinese one in 1976 killed some 250,000. But a 1556 earthquake in China killed over 800,000!
The Chicxulub (Yucatan) asteroid strike about 65 million years ago killed the majority of not just individual organisms, but whole species like the dinosaurs, although there were no humans.
The only two bigger asteroid strikes (Vredefort, and Sudbury) were about 2,000 million years ago, so there were no life forms to suffer any ill effects.

heaviest how?
in terms of how big the disaster can be, it would have to be a meteorite. During the history of the Earth there have been at least 5 impacts from large meteorites. Each has lifted so much dust in the air that it has caused a "nuclear winter", wiping out anywhere between 90 percent and 75 percent of the species (the one that killed the dinosaurs was one of the small ones, at just 75 percent of animal species killed).
After that, earthquakes are probably what can cause the most destruction and death, and they're also what releases the most energy. Some earthquakes have killed in the 100'000 and that's a lot to me.
Then would come volcano eruptions, which can be massive but will never kill 100'000 unless you're really unlucky.
Floods will typically have less total energy than, say, an earthquake, but some very bad floods can kill 100'000 or more (for example a simple flood in a coastal area), even if they will look "quieter" than a big earthquake.
Hurricanes, compared to all the above, contain much less energy, and for all the Katrina talk, cause much less destruction or death. But they can be more frequent.
Hope this helps

I'm not sure in exactly which terms you mean, but the worst recent ones I can think of were the San Francisco earthquake of 1906, Krakatoa exploding (they heard the noise in New Zealand), the volcanic eruption in Martinique (1920's? not sure), Vesuvius burying Pompeii and Herculaneum in 79AD, the recent Middle Eastern earthquakes and the awful tsunami that hit Asia the year before last.
Going further back, one of the theories about the extinction of the dinosaurs was that Earth was hit by a large meteorite which screwed up the climate so that it was winter for several years.
I've probably missed several out, but that's all I can think of right now. Good luck to your son!

Not sure what you mean by "Heaviest", but in terms of most deadly, traditionally volcanic eruptions have killed more people than other deadly disasters. This is because in addition to those killed in the immediate area (see Pompei, and Krakatoa), they often cause earthquakes and Tsunamis, killing thousands more.
The deadliest disaster of all time, however, is meteor strikes. It is estimated that millions of years ago, a single meteor killed 90% of all lifeforms, and began the ice age.

Tthe biggest killer of humans of all time was the "Spanish" influenza epidemic of 1918 -1919. It's estimated though that 74,000 years ago a volcanic eruption in what is now Indonesia killed off all but 2000 humans and we are all descended from them. So it's a matter of proportion, also of what you define as a natural disaster.

Hurricanes and earthquakes cause a lot of monetary damage but don't really "destroy" the environment. They change the environment but don't have as much of an impact as other natural disastors.
Tsunami's and volcano eruptions cause much larger environmental damage. A lot of the earth's "surface" within the range of a tsunami or lava flow will get obliterated.

I agree that bh8153's answer is the most complete. I only add that the Chicxulub strike killed most of the more developed species and allowed the lower level, mammals, to survive ... beginning the age of the mammals which evolved into today's structure.

The biggest natural disaster ever in U.S. history, was actually Hurricane Katrina. Weird to think how that JUST happened. =(

Not any natural disaster is less effective. All will mark human 's life as the slap of god!.
