Science Buddies' first grade science projects are the perfect way for
first grade students to have fun exploring science, technology, engineering, and math (STEM). Our
first grade projects are written and tested by scientists and are specifically created for use by students in the
first grade. Students can choose to follow the science experiment as written or put their own spin on the project.
For a personalized list of science projects,
first graders can use the Science Buddies Topic Selection Wizard.
The wizard asks students to respond to a series of simple statements and then uses their answers to recommend
age-appropriate projects that fit their interests.
It is fun to shake up a snow globe and watch the "snow" slowly fall. You can imagine that if the snow fell down very quickly it would be disappointing. But there are times when scientists in a laboratory want this to happen. Scientists use samples that have liquid mixed with small, solid pieces (like the inside of a snow globe), and they need all of the solid pieces in a clump, separated from the liquid. Instead of waiting for the pieces to slowly fall out of the liquid, scientists speed up…

You will need to purchase the centrifuge tubes online. See the Materials and Equipment section for details.
Have you ever ridden on a hovercraft? It is like gliding on a cushion of air! In this science project, you will make your own mini hovercraft using a CD or DVD and a balloon and investigate how the amount of air in the balloon affects how long the hovercraft hovers.

If using epoxy, adult assistance is required, use caution, and follow all of the instructions and safety warnings on the packaging.
Can you remember all of your ABC's? Computers need to "remember" letters too. Every time we use a computer to write a story, the computer needs to "remember" the letters in the story by saving them to the computer's memory as a file. In this experiment find out how much memory it takes for the computer to "remember" a series of letters.
Are you good at remembering addresses and phone numbers? How many numbers do you think you can remember? Try this experiment to test your digit span, the maximum number of digits that you can remember.
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!
Worms are slimy, wiggly, and gross. But did you know that they have many unique abilities? One of the neatest things that worms can do is regenerate, or re-grow, parts of their body. After a piece of a worm is cut off, it can grow back with all of the necessary new parts. How much of a worm can you cut off and still get regeneration? Is one end of the worm better at regenerating than the other? See if you can make heads or tails of this wiggly problem!
Have you ever been swimming at the beach and gotten some water in your mouth by mistake? Then you know that the ocean is very salty. But what about other bodies of water? How much salt do they have compared to the ocean?
Juice boxes are so convenient—just poke the straw in and sip away! But have you ever noticed that some juice boxes don't seem to have much juice, even when they have a lot of packaging? It might surprise you how much thought goes into the design and manufacturing of a juice box. Each manufacturer has carefully calculated how big each side should be to hold a certain amount of juice inside. In this science project, you will find out how different brands of juice measure up.
