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.

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.
Lesson Plan Grade: Kindergarten-5th
Students determine the coefficient of restitution (or the elasticity) for super balls. Working in pairs, they drop balls from a meter height… Read more
Lesson Plan Grade: 2nd
When discussing material properties, most of us usually think of solid materials and material properties such as hardness, flexibility, or strength. However, liquids are characterized by distinct properties, too. Some of these properties overlap with those of solids, like density or transparency, but others are more specific to liquids. Viscosity—the resistance of a fluid to flow—and surface tension, are two examples of properties that are specifically used to characterize liquids.… Read more
NGSS Performance Expectations:
  • 2-PS1-1. Plan and conduct an investigation to describe and classify different kinds of materials by their observable properties.
Lesson Plan Grade: 2nd-6th
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.
Lesson Plan Grade: Kindergarten-2nd
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.
Lesson Plan Grade: 2nd
In this lesson, students will build three-dimensional play dough models from pictures that show various landforms and bodies of water. As they analyze and compare their different models, students will realize that there are many different types of landforms and bodies of water on Earth. Based on their play dough models, students will discuss how various landforms and bodies of water can be represented on a map. Read more
NGSS Performance Expectations:
  • 2-ESS2-2. Develop a model to represent the shapes and kinds of land and bodies of water in an area.
Lesson Plan Grade: 2nd
In this lesson plan, students investigate different types of water bodies on Earth by making models of lakes, oceans, and rivers inside an aluminum pan using various materials and real water. By describing each water body and sharing their observations about their differences and similarities, students will be able to identify the typical characteristics of each water body. Read more
NGSS Performance Expectations:
  • 2-ESS2-2. Develop a model to represent the shapes and kinds of land and bodies of water in an area.
  • 2-ESS2-3. Obtain information to identify where water is found on Earth and that it can be solid or liquid.
Lesson Plan Grade: Kindergarten-2nd
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.
Lesson Plan Grade: 2nd
Steel, concrete, wood—real bridges are built from many different materials. How do engineers decide which materials to use? In this activity, your students will expand on the previous paper bridges lesson plan by building and testing bridges made from different materials. Read more
NGSS Performance Expectations:
  • 2-PS1-2. Analyze data obtained from testing different materials to determine which materials have the properties that are best suited for an intended purpose.
Lesson Plan Grade: Kindergarten-5th
What do plants need? Students examine the effects of light and air on green plants, learning the processes of photosynthesis and transpiration. Student teams plant seeds, placing some in sunlight and others in darkness. They make predictions about the outcomes and record ongoing observations of the condition of the stems, leaves and roots. Then, several healthy plants are placed in glass jars with lids overnight. Condensation forms, illustrating the process of… Read more
