Students will love these STEM Challenges! These NGSS STEM activities will have students using design thinking and conducting fair tests for these engineering challenges. Teachers will love that the materials are inexpensive and easy to find.

In this second set of STEM challenges, students will experience different challenges than in STEM Engineering Challenges Set One NGSS STEM Engineering Challenges 3-5-ETS1-1, 3-5-ETS1-2 and 3-5-ETS1-3 All of these challenges can be used separately and in any order.

NGSS STEM Engineering Challenges for 3rd through 5th grade!

Students will watch a slideshow about Fair Tests and variables. Students will learn about fair testing, variables, and design thinking. Students will create a prototype, test it and record the results, students will then adjust the design by changing the independent variable. Test the new design and record the results.

This resource includes 5 different STEM challenges. Each challenge has a detailed lesson plan with photos of student work samples. Response pages are included. Tips for teachers, questions for discussion, and BIG Science ideas are included for each challenge.

Students will use critical thinking, collaboration, communication, and creativity in these fun activities.

Great for STEM camps, Science Camps, Summer Science, School Programs, and in-class activities. Would you like to see the balloon cars in action?

This resource is designed to meet the NGSS standards for 3rd-5th grade.

3-5-ETS1-1. Define a simple design problem reflecting a need or a want that includes specified criteria for success and constraints on materials, time, or cost.

3-5-ETS1-2. Generate and compare multiple possible solutions to a problem based on how well each is likely to meet the criteria and constraints of the problem.

3-5-ETS1-3. 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.

Students will use ALL Science and Engineering Practices

Asking questions (for science) and defining problems (for engineering)
Developing and using models
Planning and carrying out investigations
Analyzing and interpreting data
Using mathematics and computational thinking
Constructing explanations (for science) and designing solutions (for engineering)
Engaging in argument from evidence
Obtaining, evaluating, and communicating information
Students will enjoy these easy to do STEM Challenges
