Science Fair Project Idea
Do you like to climb trees? The branches of trees are what make them so fun to climb. Each branch starts out as a tiny shoot that grows out from a stem. How is the growth of shoots along a stem regulated? Read more

Science Fair Project Idea
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thumbnail Do you like to watch outdated science fiction and cheesy horror movies? Many fictional tales of cloned organisms have been created based upon the scientific method for cloning animals or plants. In the real world, the cloning of plants is a common method used in modern farming. How do you clone a plant? In this science project you will get to find out by making your own cabbage clones!

Science Fair Project Idea
Leaves grow in a different pattern than stems and shoots. They do not elongate along one axis, but instead spread out over time. Do all regions of the leaf grow equally? You can use markings on different regions of a growing leaf to see if the whole surface grows, or if growth is focused in a particular region, like the veins or edges of the leaf. If you look along a leafy stem, you may notice that leaves at different positions along the stem are different sizes. You can do an experiment to… Read more

Science Fair Project Idea
Ladybugs are common insects in North American gardens that prey upon aphids, making them all the rage in biological pest control. Ladybugs can be bred in captivity making them a good insect to study. Just chop off an aphid infested plant stem for food, make a water soaked cotton ball for water, and add to a small plastic container with a lid to make a breeding box. You can use ladybugs collected from the wild, or buy ladybugs from your local nursery. The most common species is the 12-spotted… Read more

Mushrooms are not plants, but are fungi. Fungi include mushrooms, molds, and lichen. They do not produce seeds to reproduce like some plants. Fungi produce spores, like more primitive plants do. The spores of a mushroom are contained in the tiny folds around the stem underneath the mushroom cap. Different species of mushrooms have different types of spores, with different colors and different patterns of folds. You can make mushroom prints by removing the stem from a mushroom and placing the… Read more

Safety Do not eat any mushrooms that you find growing in the wild.
Science Fair Project Idea
Some sequences of RNA can catalyze biochemical reactions, much like protein enzymes. These catalytic RNA sequences are called ribozymes. The function of a ribozyme depends upon the primary sequence of the RNA which folds into a 3-D structure. How do different ribozyme sequences fold? You can search for ribozyme sequences using Entrez BLAST (NCBI, 2006). Then you can use a program like MFOLD () to submit your sequence for an analysis of its predicted 3-D structures based upon thermodynamics… Read more

Germination is the process by which a seed emerges from the seed coat. Many different variables can effect the process of germination. Try to sprout seeds from different species of plant to see if different species vary in germination time. Are weeds faster germinators than vegetables? Try measuring seeds and then germinating them to see if big seeds sprout at a different rate than small seeds. Try sprouting seeds in different environments to test the effect of different environmental… Read more

Science Fair Project Idea
Some plants grow only in water-logged environments. These plants are usually native to wetlands and are important for the sustainability of aquatic ecosystems. Wetland ecosystems are very fragile and susceptible to the toxic dumping of sewage and fertilizer run-off from neighboring farm land. One very common aquatic plant called duckweed inhabits many wetland marshes. Duckweed grows by asexual reproduction and floats at the surface of the water with tiny roots extending into the water below.… Read more

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
