Do you want to build a Snowman? In this Winter STEM Challenge, students receive a letter from the STEM snowman stating that there is a snowman building contest. In order to win, students must build the tallest snowman using only the materials provided. This is an excellent engaging activity for students to work on during the winter months! The Engineering Design Process: Students plan, design, and execute their own ideas. After they have completed their activity, there is time for reflection on what worked and what didn't. They follow the six step Engineering Design Process: Ask, Imagine, Plan, Create, Experiment, Improve. Aligns with NGSS(Next Generation Science Standards).

"I started teaching in December and knew that I wanted to incorporate STEM into my classroom as much as possible! I used this as my first STEM lesson in my class and the students loved it! They really did great! Now we do a STEM project weekly!!" - Miss R. "I've been so excited to start STEM activities this year with my second graders. I know they are going to love this pack and the part I'm most excited about is the little booklets I can print to give to each of my students for them to plan and reflect on their project. That makes it so much more meaningful to them. Thank you!" - Aimee B. "This activity offered my students a nice "break" from our traditional flow while still requiring them to think and to communicate and reason with one another! It was a great addition to our winter fun!" - Elizabeth A. "I used this for our school's Science Discovery Night and it was extremely popular! Our table was packed with kids for the hour and a half! We had a blast!" - Cresta H. "My first graders worked with their kindergarten buddies on the snowman stem project. They were challenged, creative, and had fun at the same time." - Heather H. "I did this with my fifth graders who all thought it was going to be super easy but they found out it wasn't as easy as they hoped. They really had to think! Thanks for a great resource!" - Rebecka S. More Winter STEM Activities that your students will love!

K-2-ETS1-2 Engineering Design Develop a simple sketch, drawing, or physical model to illustrate how the shape of an object helps it function as needed to solve a given problem. Grades 3-5 3-5-ETS1-2 Engineering Design Generate and compare multiple solutions to a problem based on how well each is likely to meet the criteria and constraints of the problem. 3-5-ETS1-3 Engineering Design Plan and carry out fair tests in which variables are controlled and failure points are considered to identify aspects of a model or prototype that can be improved.
