30 Inventive 6th Grade Science Projects

What makes ice melt fastest? Air temperature, humidity, and how cold something is affect this. Some factors matter more than others.

Build your own Roomba Maze game using just Lego. This project is easy and fun for anyone trying something new.

Build a pumpkin launcher is one science project. Students build a catapult from Legos. They also make a tower to launch a pumpkin. This catapult project teaches physics lessons in class.

Lemon volcano experiments show how a chemical reaction changes based on different factors. These factors affect the reaction's final result.

A shaker slime is powder that coats your skin, making it feel slimy and wet. People who have done this know the feeling of getting goo on them.

This project shows how lemons react to different acids, like vinegar and baking soda. The results look interesting and work well for younger students starting science.

Eggs are fragile and daunting. Tiny eggs have a delicate yolk and shell. Saving eggs from breaking is a difficult and fun challenge.

Making giant soap bubbles is a fun, simple science project. Kids can do this in class, at home, or anywhere. It makes learning fun.

Build a model rocket that launches into the sky. Design it for maximum height. Attach parachute-like fins at different points for rocket stability.

A paper cup anemometer is perfect for a 6th-grade science unit. It is easy to build, lasts long, and serves as a great tool for students.

Lava lamps are novelty lamps. Their fluid looks like actual lava flow. This experiment teaches you how lava lamps work.

Traffic lights operate interestingly. A sensor on the road detects vehicles passing over it. When a car passes, it sends out a radio signal at about 10 kHz.

This experiment extracts and amplifies strawberry DNA. You get this DNA by crushing a strawberry and running it on a gel.

A crater is a bowl-shaped hole or ground sunk below the surrounding area. Different geological processes create craters based on the material involved.

First, think about the questions you want to answer in a science project. This experiment sought to find out if raisins move when they are not on the top or bottom shelves.

The paper ball is a simple toy. It lets people have fun and use their creativity. This simple design gives the paper ball many uses. Paper ball runs are one type; people build a device to move the balls or let gravity do the work.

Oobleck is a non-Newtonian fluid. Its viscosity changes based on pressure. Mixing corn starch and water to the right consistency creates this goopy mess.

Examine how gumminess relates to pH level in the simplest gummy bear project for 6th graders. Students test this idea by taking a tray of gummy bears with fruit juice, half with water, and half with vinegar.

Many children ask parents to make an upside-down water experiment. This is a fun, easy science project. It shows density and how liquids act when turned upside down.

This experiment shows students how an invisible object can act as a fire extinguisher. The experiment uses water, detergent, and paper towel to make an invisible smoke cloud. This cloud can put out real fires, like ones in a lab or on stage.

Caffeine is a compound plants use to boost chlorophyll and nutrient absorption. Using data from real experiments, this offers a science review of how caffeine affects plant growth.

Clouds in a bottle is a popular science fair project. Many 6th graders create their own cloud. They place it on a soda can and freeze it to make a portable cloud to keep at home.

This project is a STEM activity a 6th grader might build for science fair. The goal is to make the tallest paper tower possible. Students must think about materials and how they will build the tower.

An electromagnet is an object, usually a wire coil. It generates an electromagnetic field when electric current is applied. The coil's shape and current strength direct this magnetic field.

A marble run is a popular elementary school science experiment. It is easy to build and simple to test. You build a marble maze and place marbles at different points on the track, testing how fast they go down to the bottom.

Science offers many fun methods. Make a toy robot or gadget to do science. This project shows you how to build a Wiggle Bot, like the one we made in class, using only paper, tape, and an elastic band.

Kids enjoy making buzz wire games at home and showing them to friends. The buzz wire game uses an old shoelace and hanging beads so the wires jingle as they move up and down. These games teach kids gravity, motion, and math simultaneously.

This experiment made the water in the bowl feel alive. You use a light bulb to create a small amount of electricity in a copper wire. Then, place two metal sheets on opposite ends of the light bulb to form a bridge with equal metal on both sides.

This article covers how solar cells function and their efficiency. It includes a scientific chart ranking solar cells and their energy conversion efficiency. People use solar cells daily to generate electricity for homes and businesses.

Use ice, cold water, and salt. Use snow. Put it in the freezer. Blow on it hard enough to build condensation on the edge of the can or bottle cap.
