Second Grade Lesson Plans (22 results)

Science Buddies' second grade science projects are the perfect way for second grade students to have fun exploring science, technology, engineering, and math (STEM). Our second grade projects are written and tested by scientists and are specifically created for use by students in the second grade. Students can choose to follow the science experiment as written or put their own spin on the project.

For a personalized list of science projects, second graders can use the Science Buddies Topic Selection Wizard. The wizard asks students to respond to a series of simple statements and then uses their answers to recommend age-appropriate projects that fit their interests.

Let us help you find a science project that fits your interests, with our Topic Selection Wizard.

7 reviews
Add a twist to a classic activity with this fun lesson plan. Your students will design and build a ball run for a ping pong ball using nothing but paper and tape. Their goal is to make the slowest ball run possible. How long can they make it take for the ball to go through their ball run? An optional variation is available if you would like to give students an extra challenge. The 2026 Engineering Challenge has ended. You can still do this challenge with students informally. Read more
NGSS Performance Expectations:
  • 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.

"Grasshopper" by Ryan Wood There are thousands of species of insects in our world, and each are adapted to survive in their habitat. In this activity, students will learn what an insect is and what some of their adaptations are. Then they will put their knowledge into play by "creating" an insect that is adapted to live in their assigned environment. Read more

Your students have probably walked or ridden over a bridge at some point in their lives. In this engineering activity they will design and make bridges out of folded pieces of paper, and test how much weight they can hold with pennies. How does the shape of a bridge affect its strength? Let your students explore and find out with this lesson! This lesson can be expanded to a second lesson looking at how the material a bridge is made out of can change its strength; see second lesson for details. Read more
NGSS Performance Expectations:
  • K-2-ETS1-2. 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.
  • K-2-ETS1-3. Analyze data from tests of two objects designed to solve the same problem to compare the strengths and weaknesses of how each performs.
The Role of Interdependence for Pollination and Seed Dispersal

Pollination and seed dispersal are both crucial processes in a plant's reproduction cycle. These processes are helped along by many factors, including different animals. For instance, some animals disperse the plant seeds, while others transfer pollen from one flower to another. In this lesson plan, students will investigate the interdependence between plants and animals for pollination and seed dispersal by creating interdependence webs out of yarn. Based on their created interdependence webs,… Read more
NGSS Performance Expectations:
  • 2-LS2-2. Develop a simple model that mimics the function of an animal in dispersing seeds or pollinating plants.
Make a Miniature Habitat

Get creative with your students in this hands-on lesson plan! Students will use mostly natural materials to build a shoebox habitat that mimics a real-life habitat for an animal of their choice. As they present their miniature habitats to each other, students realize that not all habitats are suitable for all animals. Each animal species needs the resources of a specific habitat to survive. Read more
NGSS Performance Expectations:
  • K-ESS-3-1. Use a model to represent the relationship between the needs of different plants and animals (including humans) and the places they live.
  • 2-LS4-1. Make observations of plants and animals to compare the diversity of life in different habitats.>/li>
Water Transport in Plants

Your students might know that plants need water to survive. But how does a plant "drink" and get water from the soil all the way up to its' leaves? In this lesson plan, students will observe how plants (flowers and celery) suck up dye-stained water, which makes the petals and leaves change color! This allows students to visualize the process of how water moves through a plant. Read more
NGSS Performance Expectations:
  • 2-LS2-1. Plan and conduct an investigation to determine if plants need sunlight and water to grow.

"Close-up of Coral Polyps" © 2009 Mark Yokohama By building an edible coral polyp, students will learn the anatomy of coral and be able to explain why corals are animals, rather than plants. Read more
NGSS Performance Expectations:
  • 4-LS1-1. Construct an argument that plants and animals have internal and external structures that function to support survival, growth, behavior, and reproduction.

Computational thinking is a problem-solving process that is used in everyday life as well as computer programs. In this lesson, students apply their computational thinking skills to explore the life cycle of a butterfly. They'll create an algorithm, or set of instructions, to model the life cycle of a butterfly. They will write this algorithm using conditionals and then program it on a computer. Learning Objectives Students will: Analyze the life cycle of a butterfly. Develop an algorithm… Read more
Designs in Nature: Investigate the Branching Structure of Trees
Lesson Plan Grade: Kindergarten-2nd
Nature is full of objects with many different shapes. Some of these shapes display obvious regularities or distinct patterns, such as stripes, waves, symmetry, or spirals. Each of these natural patterns has evolved over a very long time and serves a specific function that usually helps a plant, animal, or other organism to survive. In this lesson plan, students explore the branching pattern of trees, plants, and leaves. They will make drawings and a leaf rubbing to compare different branching… Read more
NGSS Performance Expectations:
  • K-2-ETS1-2. 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.
