Life on Land, Plant Biology Science Projects (30 results)

The United Nations Sustainable Development Goals (UNSDGs) are a blueprint to achieve a better and more sustainable future for all.
These projects explore topics key to Life on Land: Sustainably manage forests, combat desertification, halt and reverse land degradation, halt biodiversity loss.

Plants provide us with so much — oxygen to breath, food to eat, materials to make clothing and paper, and beautiful flowers and leaves to admire! How can plants be so diverse and survive in so many kinds of climates? How do they know how to grow towards the sun? Why do some plants not have seeds? Explore the amazing and beautiful world of plants.

Scientific Method
Have you ever seen a (non-carnivorous) plant eat? Probably not! Plants do not get the energy they need from food, but from the sunlight! In a process called photosynthesis, plants convert light energy, water, and carbon dioxide into oxygen and sugar. They can then use the sugar as an energy source to fuel their growth. Scientists have found an easy way to measure the rate of photosynthesis in plants. The procedure is called the floating leaf disk assay. In this plant biology project, you can… Read more

Scientific Method
As we humans zip from place to place, we often forget to stop and smell the roses. Compared to our fast-paced lifestyle, plants seem rooted to the spot. Don't be deceived by appearances however, plants are on the move! This experiment will investigate the stimulus/response relationship in plants and prove that plants can move up and down in response to gravity. Read more

Scientific Method
Up, up, and away! If you have ever made a wish and blown the fluff of a dandelion, you have witnessed how some plants are adapted to spreading their seeds using the wind. The tiny, furry parachute allows the seeds to be picked up by the wind and to be carried far away from their parent plant. In this experiment, you will make models of seeds and fruit to investigate dispersal by wind and to evaluate the relationship between the structure of the seed and its ability to be dispersed by the wind.

Scientific Method
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

Scientific Method
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

Scientific Method
Plants move—not very quickly compared to animals, but they do move. Their roots grow downward in response to gravity, and their stems grow upward toward the Sun. In this plant biology science fair project, you will investigate how young plants respond through movement to light. Read more

Scientific Method
To be able to live on Mars, humans need breathable air, clean water, and nutritious food. Spacesuits can provide oxygen to breathe, ice on Mars can be a source of water, but how could we get nutritious food? Today's astronauts bring food with them. But a manned trip to Mars would require food that was either successfully grown in space or on Mars, as taking the extra weight of food for such a long time—it takes 6–9 months one way—is just too costly. In this project, you will… Read more

Scientific Method
Global warming is how scientists describe the gradual warming of our global climate. Scientists think that the trend towards global warming can be attributed to the build up of greenhouse gases in the earth's atmosphere from industrialization. Another problem is deforestation, as we remove plants and trees from the environment to meet a high demand for lumber or by clear cutting fields for farming and urbanization. By removing trees from the earth's environment, are we changing how greenhouse… Read more

Scientific Method
Flower development is an important part of plant growth. When a plant has reached maturity, it needs to develop flowers in order to reproduce. The male and female parts of the flower have specialized structures for reproduction that develop as the plant matures. How do flowers develop over time? Which structures develop first? You can answer these questions by dissecting the flowers of a gladiola. Gladiola flowers grow and develop along the stem, with the most mature flowers opening at the… Read more

Scientific Method
Everyone loves the beautiful colors of fall, but where do they come from and how does the change in colors happen? In this project, you will uncover the hidden colors of fall by separating plant pigments with paper chromatography. What colors will you see? Read more
