Valentine's Day STEM Activities Cardiac STEM Challenges Sound Force and Motion
Try these Valentine's day STEM challenges with your students! If you are exploring the heart, sound, or biomedical engineering, this is a great hands-on activity for students to try. They will create a stethoscope to hear a heartbeat (or sound through earbuds or a speaker). Students will also explore force and motion with a paper heart tower that is easy to set up but tricky to master. Students will need to use trial and error as well as balancing skills to craft this tower! ❤️ What You'll Get

STEM Activities & Challenges: 2nd & 3rd Grade Simple Machines Leprechaun Trap
St. Patrick's Day Leprechaun Trap STEM Project-Based Learning is here! This STEM activity and challenge for 2nd-3rd graders uses the concepts of simple machines (pulleys, levers, inclined planes/ramps) and the engineering design process to engage students in the challenge of building a leprechaun trap that can trap and contain a marble or ping pong ball (representing a leprechaun). Step-by-step directions and materials list are both provided for the teacher to allow for maximum student success.

Snowball Launcher — Projectile Motion STEM Challenge (Grades 3–12, NGSS Aligned)
Title: Snowball Launcher — Projectile Motion STEM Challenge (Grades 3–12, NGSS Aligned)Description (emoji-friendly): Launch into winter physics! ❄️ Students test a paper-ball or pom-pom “snowball” launcher to explore projectile motion. Teams hold pullback constant and vary launch angle, measuring distance vs. angle to discover the peak near 45°. They graph data, justify conclusions with CER, and (optionally) estimate launch speed using the range formula. 🎯📈 NGSS Alignment: 3–5: 3-5-ET

Cranberry Bog Boat — Buoyancy & Density STEM Challenge (Grades 3–12, NGSS Aligne
Make buoyancy click with a seasonal engineering lab: students design a small foil “bog boat” that carries the maximum mass (cranberries/coins/washers) before sinking. They plan, build, test in a water bin, record data, and iterate to optimize stability and displacement—perfect for stations or a full-period lab. What students do Plan & sketch under material/size constraints, predict capacity. Test in rounds, adding equal-mass items until failure; record max mass, freeboard, and failure mode.
