Three Dynamic STEM Activities to Spark Winter Learning 

As the parent of a dedicated learner, you get a front-row seat to the incredible focus and digital fluency your child develops every day. At Michigan Great Lakes Virtual Academy (MGLVA), we see how virtual learning empowers students to master complex concepts with agility and independence. One of the most exciting ways to celebrate that mastery is by taking the theories learned in our digital classrooms and applying them to physical, tactile projects right in your own home lab. 

Integrating physical experimentation with digital instruction is a powerful way to deepen understanding and ignite a lifelong passion for discovery. Research suggests that interactive, hands-on workshops can significantly increase student enthusiasm and joy while reducing academic fatigue. By turning everyday household items into tools for innovation, these high-energy STEM projects allow students to build engineering skills and see the science in the world around them. It’s time to take those concepts off the screen and bring them to life. 

The Popsicle Stick Catapult Challenge 

Grade Level: K – 5^th Grade 

This playful engineering activity teaches fundamental physics concepts like potential and kinetic energy through a competitive game. 

Goal: Build a device strong enough to launch a small object (like a pom-pom or marshmallow) at a measurable distance. 

Materials  

• 10–12 Popsicle sticks (the more, the sturdier) 

• 3–4 Rubber bands 

• 1 Plastic spoon (the cup end acts as the launch base) 

• A small object (marshmallow, cotton ball, or pom-pom) 

Instructions 

1. Stack the Base: Stack 8 or 9 Popsicle sticks and tightly bind the ends together with rubber bands. This is your foundation. 

2. Create the Lever: Take two separate sticks and rubber band them tightly together at one end only. This creates a hinge. 

3. Assemble the Mechanism: Separate the two hinged sticks and place the stack of 8–9 sticks between them, near the rubber-banded hinge. 

4. Secure the Launch Arm: Tightly rubber band the stack to the bottom stick of the hinge. The top stick should now be sticking up, forming a large “V” shape. 

5. Attach the Spoon: Rubber band the plastic spoon to the end of the top stick (the launch arm). 

6. Launch! Place your projectile in the spoon, push down on the lever to load the potential energy, and release! 

Discussion Prompts: 

• Where did the energy come from? The energy you put into stretching the rubber band was stored as potential energy. When you let it go, that stored energy transformed into kinetic energy, making the band move. 

• How could we make the object go farther? Use more rubber bands or shorten the launch arm. 

The Blubber Glove Experiment (Supervised Activity) 

Grade Level: Pre-K – 5^th Grade 

This is a powerful biology demonstration that uses sensory input to teach students about animal adaptation and thermal insulation. 

Goal: Prove that fat layers (like blubber) are superior insulators against extreme cold. 

Materials  

• A large bowl filled with ice water 

• Shortening (Crisco or solid cooking fat)  

• Two small plastic sandwich bags or rubber gloves 

Instructions 

1. Prepare the “Blubber”: Place a large scoop of shortening into one of the plastic bags or rubber gloves. Ensure it coats all sides of the bag. 

2. Set Up: Have the child put one hand in the empty plastic bag (the control hand). Have them put the other hand into the bag containing the shortening (the “blubber”). 

3. The Test: Have the child place both hands into the bowl of ice water simultaneously. 

4. Observe: Ask them to describe the difference. They will quickly feel the biting cold on the control hand, while the hand inside the blubber will feel relatively protected. 

Discussion Prompts: 

• What did the blubber do? It prevented the cold from the ice water from directly affecting the skin, providing thermal insulation. 

• What animals use this trick to stay warm? (Seals, whales, polar bears, etc.). This demonstrates why some creatures thrive in the Great Lakes or Maine winters! 

The Spaghetti Tower Challenge 

Grade Level: 3^rd – 8^th Grade 

This activity focuses on essential Structural Engineering and Geometry concepts. 

Goal: Build the tallest, freestanding tower possible using only spaghetti and a binding material. 

Materials  

• One box of dry spaghetti (uncooked) 

• A bag of large marshmallows or modeling clay (your binding material) 

• A ruler or measuring tape 

• A tennis ball (for the strength test) 

Instructions 

1. The Design: Give the students 5 minutes to sketch a design. Introduce the concept that the triangle is the strongest shape in engineering. 

2. The Base: Start by building a wide, solid base using triangles by connecting the dry spaghetti noodles with marshmallows/clay. A wide base is critical for stability. 

3. Build Up: Build vertically, focusing on bracing—using diagonals and triangles to connect the sides and prevent wobbling. 

4. The Test: After 30 minutes, measure the height of the tower. Then, gently place the tennis ball on top. The tower must hold it for 10 seconds to succeed. 

Discussion Prompts: 

• Which shapes failed first? (Likely the squares, which buckle under pressure.) 

• Why did the triangles hold the structure together? (The force is distributed evenly across the sides.) 

• How does this relate to buildings or bridges? (Look for triangles/braces in local structures.)  

Why are these STEM activities worthwhile? 

The goal of these dynamic challenges is to celebrate active discovery and interactive learning through physical application. Using everyday household materials and simple steps, these STEM activities empower your learner to apply their classroom knowledge, sparking new levels of creativity and critical thinking. We encourage you to include one of these high-energy projects in your week to fuel your child’s learning momentum all winter long.
