STEM Fair Project Ideas for Sixth Graders

STEM Fair Project Ideas for Sixth Graders

Explore these hands-on activities, which range from creating solar-powered ovens to coding instructional games, to pique curiosity and creativity while developing critical thinking abilities.


STEM (Science, Technology, Engineering, and Mathematics) fairs offer a fantastic opportunity for sixth-grade students to explore their interests, develop critical thinking skills, and express their creativity. These projects not only help students gain a better understanding of STEM ideas but also motivate them to apply their knowledge to real-world challenges. We've created a collection of fascinating STEM fair project ideas for sixth-grade students covering various STEM subjects.

1. Solar-Powered Oven

Objective: Design and build a solar-powered oven to harness the sun's energy for cooking.

Materials: Materials include cardboard, aluminium foil, plastic wrap, black paint, a thermometer, glue, and scissors.

Method: Make a box-shaped oven from cardboard, insulate it with aluminium foil, and paint the interior surface black to absorb heat. Use plastic wrap to make a translucent lid. Measure the temperature increase over a sunny day to see how efficient the oven is.

2. Water Filtration System

Objective: Create a water filtration system to filter tainted water from household items.

Materials: Materials include plastic bottles, sand, gravel, activated charcoal, cotton balls, and unclean water samples.

Method: Cut plastic bottles to make filter chambers. Layer the materials (sand, gravel, charcoal, and cotton) in the bottles to simulate the filtration process. Pour polluted water through the system, then assess the clarity and purity of the filtered water.

3. Robotic arm

Objective: Create a robotic arm that can perform simple tasks like picking up objects.

Materials: Materials include cardboard, straws, syringes, string, hot glue, and small lightweight things.

Method: Create the arm with cardboard for the construction and straws for the joints. Use syringes as hydraulic actuators to regulate movement. Attach strings to syringes and manipulate them to simulate arm movement. Picking up objects of different sizes and weights will allow you to test the arm's capabilities.

4. Wind Turbine Experiment

Objective: To investigate the effectiveness of various blade designs for harvesting wind energy.

Materials: cardboard, straws, wooden skewers, hot glue, fan, multimeter, and several blade forms (flat, curved, and twisted).

Method: Make wind turbine blades from cardboard and experiment with different forms and sizes. Mount the blades on a central axis and link them to a multimeter to measure the voltage output when exposed to airflow from a fan. Analyze which blade design produces the most electricity.

5. Coding and Game Development

Objective: Create an instructional game with block-based coding platforms such as Scratch or Tynker.

Materials: A computer or tablet with internet connectivity, Scratch/Tynker software, and imagination!

Method: Design the game around a STEM-related theme, such as space exploration or environmental conservation. Create characters, backdrops, and gaming mechanisms with block-based code. Use instructional features such as quizzes or puzzles to reinforce STEM ideas.
