20 Easy Stem Activities for Second Grade Students – K-2 Stem Activities

STEM is an essential part of a child’s education. Especially in the early stages of education, providing students access to quality STEM lessons positively impacts their comprehension, retention, and willingness to continue learning STEM in the future. Parents and educators have the unique opportunity to introduce STEM to K-2 students for what could be the first time. This first-time experience can be used to create a positive connotation with STEM learning and build student confidence when interacting with complex concepts. In this article, STEM Sports® has compiled a list of twenty (20) STEM activities for second grade students. 

Rain Cloud in a Jar

The Rain Cloud in a Jar experiment is easy to implement with second grade students at home or in the classroom. Fun Learning for Kids also includes a printable worksheet students can use to track their progress and comprehension of the lesson. Throughout this lesson, students will learn more about the weather system and how rain leaves clouds and interacts with air as it falls toward the ground.

My Five Senses Sorting Cards

When students are starting out in their education, they will likely have questions about why something is happening and how. Using the Five Senses Sorting Cards, students will learn to differentiate what things interact with each of their senses. This is a foundational element students will use as they continue science learning in the future.

Popsicle Stick Catapult

Creating a catapult using popsicle sticks is a great way to transform students into engineers. In this lesson, students will build their base and test the effectiveness of their catapult when launching their bottle cap and cotton ball. This is a great lesson to introduce students to the Engineering Design Process (EDP). They will work through the process to figure out how to make their catapult more efficient and usable.

Binary Code Writing Experiment - No Screens!

To implement this lesson, educators or parents will print the code cards and worksheets that students will use to practice their binary coding without screens. Students will practice implementing their code strings and adding their answers to their worksheets. At the end of the lesson, students can compare their code with classmates and have their teacher provide correct answers and guidance when needed.

STEM Activity A Top of a Tower

The ‘A Top of a Tower’ STEM activity uses common household and classroom supplies to help students exercise and improve their engineering skills. This can become a challenge between family members or classmates to see who can make the sturdiest building. Once students have completed their towers, you can use pennies to see how much weight each student’s structure can hold. 

Teacher Tip: Before testing the structures, students can write predictions about how many pennies they think their structure can hold before breaking.

STEM Pattern Block Challenge

Pattern block activities are a great way to introduce STEM into the classroom – especially at the kindergarten, first grade, and second grade levels. Students exercise their problem solving, critical thinking, and motor skills while creating their pattern blocks. The STEM Laboratory has included all necessary cards and printed materials for free. If you have access to blocks, students can use those and, if not, they can color their own paper cut-outs and use those to execute the lesson.

Jelly Bean Engineering Challenge

In this engineering challenge, students are tasked with building a structure using only jelly beans and toothpicks. This activates the creative side of students’ brains and teaches fundamental problem-solving skills. This activity can be changed depending on the time of year to make it a seasonal STEM challenge! For example, as the holidays approach, students can use Christmas colored candy to build their structures.

Colorful Rainbow Density Jar

The Rainbow Density Jar experiment is a great way to introduce students to density in a colorful, engaging way! As students add additional liquids to their jar, they can see it move to a specific layer. To complete this activity, have students rank the density of the materials they used and compare their answers with classmates.

Can you Save Fred?

This activity is based on the idea that Fred the gummy worm needs to be saved. The catch is that students (the rescue team) only have paper clips. Students are tasked with working in teams to think creatively about how they can save Fred using their limited materials. This disguised learning activity turns students into engineers while teaching 21st century skills without them even knowing!
