Carson Dellosa Stem Challenges Learning Cards Bundle - 60 Hands-On Science Projects for Grades 2-5

Ignite hands-on curiosity with STEM challenges

Designed for grades 2–5, the Carson Dellosa Stem Challenges Learning Cards Bundle brings 60 full-color challenges into one portable set. Students typically ages 8–12 can explore seasons, life, physical, earth, and space science through engaging, kid-friendly activities. Each card is crafted to be approachable yet meaningful, inviting learners to experiment and observe without requiring specialized tools.

Two-sided design that guides inquiry

The front side presents the task and a visual list of materials, while the back offers hints, guiding questions, and succinct explanations of the science behind each activity. This structure helps students build plans, test ideas, and reflect on outcomes in their own words.

Real-life activities and everyday materials

Examples include building marshmallow igloos, constructing paper rockets, and executing simple experiments that travel well in a classroom center or homeschool routine. The activities are designed to be accessible with common materials, helping teachers spark curiosity with minimal prep.

Organization that supports classroom flow

Two boxed sets come with sturdy dividers to keep 60 cards neatly organized. Each card is sized for easy handling, and the dividers make it simple to rotate topics or set up focused STEM stations.
