STEM Activities for Forth Graders

STEM Activities for Forth Graders

Discover detailed hands-on tasks aimed at instilling curiosity and developing critical thinking abilities, such as creating paper bridges and coding with Scratch.


In fourth grade, children can explore STEM (Science, Technology, Engineering, and Mathematics). Participating in hands-on STEM activities not only piques interest, but also promotes critical thinking, problem-solving abilities, and a lifelong love of learning. We've collected a collection of thorough STEM activities designed exclusively for fourth-grade students, to inspire young minds and cultivate a love of exploration and discovery.

1. The Paper Bridge Engineering Challenge

Objective: Use paper bridges to teach basic engineering principles.

Materials: Testing materials include index cards, tape, scissors, books, and weights.

Method: Challenge kids to design and construct paper bridges with only index cards and tape. Encourage students to experiment with other bridge designs, such as truss, arch, or suspension bridges, and to test the strength of their structures by stacking books or weights on top. Explain the concepts of load bearing, tension, and compression.

2. Solar System Model

Objective: Create a scale model of the solar system to explore and learn about its planets.

Materials: Styrofoam balls (various sizes), paint, paintbrushes, string, wooden dowels, and glue.

Method: Instruct students to examine the characteristics of each planet in the solar system, such as size, distance from the sun, and distinguishing traits. Then, encourage students to paint Styrofoam balls to represent planets and build a size model of the solar system out of string and dowels. Encourage originality and accuracy while arranging the planets relative to the sun.

3. Ecosystem Exploration

Objective: Conduct a hands-on investigation to learn about ecosystems and food chains.

Materials: Terrarium or miniature aquarium with dirt, plants, and small plastic creatures or insects.

Method: Help students create a mini-ecosystem in a terrarium or tank using soil, plants, and plastic animals representing various trophic levels. Discuss the concept of a food chain and how energy moves across an ecosystem. Encourage children to examine relationships between living organisms and explain the value of biodiversity.

4. Simple Machines Scavenger Hunt

Objective: Identify and classify simple machinery in ordinary things using a scavenger hunt.

Materials: Materials include simple devices (lever, pulley, inclined plane, wheel and axle, screw, wedge) and ordinary things.

Method: Give students a list of simple machines and ask them to discover instances of each in their environment. Encourage them to document their findings with sketches or photographs, and talk about how each gadget makes their job easier. Facilitate a group conversation about the various types of basic machines and their uses.

5. Coding in Scratch

Objective: Use interactive coding projects to teach basic programming concepts.

Materials: Materials include computers or tablets with internet connectivity, as well as the Scratch coding environment.

Method: Guide students through beginning coding exercises in Scratch, a block-based programming language. Encourage children to make animations, games, or stories by dragging and dropping code blocks to sequence commands. Encourage kids to problem-solve and explore various coding concepts like loops, conditionals, and variables.
