Others Like “Growth and Age”

Project Idea
Trees grow more during the early spring than they do the rest of the year. Because of this period of dormancy, or lack of growth, each year of growth is marked by a line called a tree ring. You can count the number of rings in the cross section of a tree trunk to show how old the tree is. You can also count the number of rings in a stem to see the age of a stem or branch. One way to measure the rate of growth of a tree is to count the number of rings per inch. Trees with high numbers of… Read more

Plant stems grow through a process of elongation due to cell divisions within the stem. Does the entire length of the stem elongate evenly? Or do certain regions along the plant stem grow more or less than others? Regions that are involved in active growth are called vegetative. You can conduct an experiment to show which regions of a bean seedling are involved in vegetative growth. Use a marker to mark one inch sections along the main stem of a young bean seedling. Number the regions 1-6… Read more

thumbnail In the first decade of the 21st century, scientists found ways to make one adult cell type turn into a completely different cell type. This has huge implications for the medical field, including being able to take some cells that a person could spare, such as skin cells or blood cells, and turn them into another cell type that might be much more important for that person to have, such as cells to make a new kidney. How are scientists able to accomplish this amazing feat of "reprogramming" the… Read more

The conversion of forested to unforested areas has been occurring since humans began to impact and change their environments during the agricultural revolution. Recently deforestation has become a global problem, particularly for developing industrial countries and countries with very large populations. You can use satellite mapping resources to investigate the connection between urbanization, population growth and deforestation. You can also investigate the connection between deforestation… Read more

thumbnail Have you ever wondered where acne comes from and how you can treat it? One major cause of acne is the colonization and infection of clogged pores with bacteria. In this science project, you'll test different acne medications and treatments to determine their effectiveness at killing bacteria. Read more

Time Required Long (2-4 weeks)
Prerequisites None
Material Availability This science project requires access to some laboratory equipment, such as a 37°C incubator, as well as some specialty reagents, which can be ordered online. See the Materials and Equipment list for more details.
Cost High ($100 - $150)
Safety This science project involves the use of the bacterium E. coli. Standard microbiology and bacterial safety guidelines should be followed, see the [# ProjectGuide Name="Advanced.MicroorganismsSafetyGuide" Value="HtmlAnchor" HtmlShortTitle="true" #] for more details. To maintain a sterile environment, you will be working near a lighted Bunsen burner. Keep all flammables, including hair and clothing, away from the flame.

Reclaimed (treated) wastewater can be used for many purposes, including landscape watering and freeing up valuable fresh water for other purposes (like drinking water). It's a great way to conserve water, but is it really safe? This science fair project is designed to find out. Read more

First came the and now (drum roll please) the . Confused? Not surprising as the Human Proteome Project has not received the kind of press that the Human Genome Project did. Nonetheless it is a major, and potentially important, scientific undertaking. Just as the genome is the complete set of an organism's DNA, the proteome is all the proteins expressed in an organism. Why study the proteome? It is because proteins are the work horses of biological systems, performing all of the biochemical… Read more

Project Idea
thumbnail The human kidney is the most commonly transplanted organ in the United States, numbering more than 17,000 transplants in 2010 alone! But kidney transplantation technology faces a lot of challenges, including a shortage of kidney donors and the need for recipients to take immunosuppressant drugs to keep their bodies from rejecting a transplanted kidney. In this science project, with the help of bioinformatics databases, you will explore how a kidney could be bioengineered using stem cells,… Read more

Some people worry that modern electronic devices can give off harmful electromagnetic radiation, called EMF. Test your computer, radio, cell phone, computer, TV, or microwave for electromagnetic radiation. You can also try growing a sensitive organism, like flies, yeast or worms, to see if a potential source of electromagnetic radiation has an effect on them. Is it a myth, or will your cell phone fry your brain? Read more

thumbnail 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
