Observe Something in Nature Science Projects (16 results)

Go outside into the natural world and carefully observe one aspect to discover the answer to a science question. Take a measurement of stars or the moon, or look underneath your feet to investigate moss or soil bugs.

Suck It Up: Capillary Action of Water in Plants
Science Fair Project Idea
Scientific Method
Have you ever heard someone say, "that plant is thirsty" or "give that plant a drink of water"? We know that plants, and even bouquets of cut flowers, need water to survive, but have you ever thought about how the water moves within the plant? In this science project, you will use colored water and carnations to figure out where the water goes. Read more
Moss is Boss: Using Plants to Determine Direction
Science Fair Project Idea
Scientific Method
Have you ever gone camping, looked up at the stars, and found the Big Dipper? Two stars in the dipper part of this constellation point to Polaris, the north star, which people have used for thousands of years to help them find their way. In this plant biology science fair project, you'll investigate whether plants, like moss, can help you find your way, too. Read more
Jumping For Geodes: Can You Tell the Inside from the Outside?
Science Fair Project Idea
Scientific Method
Have you ever heard the expression, "You can't judge a book by its cover"? What do you think that means? That a book with a very plain cover might have a very exciting and interesting story inside? Well, in this geology science project, you'll see if the same expression holds true for a rock, but not just any old rock, a special type of rock called a geode, which looks rather plain and ordinary on the outside, but inside can hold crystals and beautiful colors! You'll discover if the texture or… Read more
Are There Bugs Under Your Feet?
Science Fair Project Idea
Scientific Method
Look out! When you walk on the grass, you are squishing millions of micro-invertebrates! Just kidding, these animals are too small to squish. Learn how to catch them by making a Berlese funnel in this fun project that will teach you about soil. Read more
How Many Seeds Do Different Types of Fruit Produce?
Science Fair Project Idea
Scientific Method
Do you like your strawberry jelly with or without the seeds? Are you glad to have a seed-free watermelon, or do you enjoy spitting the seeds into the garden? You might not like to find seeds in your fruit, but fruit is the plant's way of dispersing seeds to make new plants. How many seeds can be dispersed for each type of fruit? As they say, in one end and out the other! Read more
Using a Digital Camera to Measure Skyglow
Science Fair Project Idea
Scientific Method
This is a great project for someone interested in both stargazing and photography. Bright city lights and even the light of the full Moon obscure the dimmest stars, which can make identifying constellations more difficult. In this astronomy science project, you will calibrate a digital camera to measure the skyglow in different locations. This can be a great tool to comparing the quality of different star viewing locations. Read more
The Moon and the Stars
Science Fair Project Idea
Scientific Method
Everyone loves looking at the full moon, but are these nights the best time to go stargazing? Can the moon interfere with certain astronomical observations? Read more
How Do Flowers Develop?
Science Fair Project Idea
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
Measuring the Moon's Brightness
Science Fair Project Idea
Scientific Method
Sometimes a full moon can be so bright, you can walk around in the dark without a flashlight. How much brighter is a full moon than the other phases of the moon? How is the brightness of the moon measured? Read more
Froggy Forecasting: How Frog Health Predicts Pond Health
Science Fair Project Idea
Scientific Method
Have you ever heard the expression "a canary in a coal mine"? In the 1900's and earlier, coal miners brought canaries with them into the mines to act as early warning signals. The canaries were very sensitive to low levels of dangerous gases, so if the birds stopped singing, or got sick, then the miners knew to leave immediately, even if they felt fine. As it turns out, our froggy friends are also very helpful at signaling problems, not in mines, but in and around bodies of water. Try this… Read more
