Landslides

Science Fair Project Idea

Scientific Method

What causes landslides? The USGS Landslide Hazards Program conducts research needed to answer major questions related to landslide hazards. Where and when will landslides occur? How big will the landslides be? How fast and how far will they move? What areas will the landslides affect or damage? How frequently do landslides occur in a given locality? Investigate the patterns of landslide occurrence in your area. Are they related to locations, geology, or topography? Are they more frequent… Read more

Latitude and Weather

Science Fair Project Idea

Scientific Method

How does temperature vary with latitude? What happens as you move away from the equator? Test this by comparing weather data from weather stations at different latitudes. (FI, 2006; GLOBE, 2006; NCAR, 2006; NOAA, 2006; Unisys, 2006; Weather Underground, 2006; WMO, 2006) Read more

Lichenometry: An Accessible Method for Dating Recent History (Geological and Manmade)

Science Fair Project Idea

Scientific Method

Have you ever noticed an old stone wall and wondered how long it has been there? If there is lichen growing on the wall, the lichen has most likely been living there since the time the wall was made, so if you could figure out how old the lichen is then you could deduce the age of the wall. Geologies use this method, called lichenometry, and other methods to establish dates and temporal sequences as they seek to construct a history from the available evidence. In this geology science project,… Read more

Your liver is important for cleaning up any potentially dangerous substances you consume. But how does it do it?—With a little help from some complex chemistry. Within your liver, as within every tissue in the body, many chemical reactions occur. Often these reactions require "help" to happen at a faster speed, and this can be supplied by enzymes—tiny types of proteins. The liver uses specialized enzymes to help it break down toxic substances and make them safer for the… Read more

Lunar Crater Counting

Science Fair Project Idea

Scientific Method

Get good photographs of the Moon showing lots of craters and count how many craters you find in a range of diameter classes. One useful source is the Consolidated Lunar Atlas (Kuiper et al, 2006). Make a histogram that shows the distribution of diameters. Most of these craters were formed during the first billion years of the Moon's formation, but you should confirm that this is true for the the Moon areas you've selected in your photographs by doing background research. Is cratering uniform… Read more

Macro for Micro?

Science Fair Project Idea

Scientific Method

If the prefix "macro" means large and "micro" means small, then why will the macro setting of a digital camera help take a better picture of a small object? Do this experiment and get the big picture. Read more

Magic Squares

Science Fair Project Idea

Scientific Method

A magic square is an arrangement of numbers from 1 to n2 in an n x n matrix. In a magic square each number occurs exactly once such that the sum of the entries of any row, column, or main diagonal is the same. You can make several magic squares and investigate the different properties of the square. Can you make an algorithm for constructing a Magic Square? Can you show that the sum of the entries of any row, column, or main diagonal must be n(n2+1)/2? Are there any other hidden properties of a… Read more
