Free science lesson plans designed to engage students through hands-on experiments and activities. Chemistry, life sciences, physics, engineering and more, for elementary, middle and high school teachers.
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 for details.

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.
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 by building and testing bridges made from different materials.

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.
What goes up, must come down in this thrill-seeking lesson plan! How much energy does a roller coaster car need to make it through a loop? In this lesson your students will learn about kinetic and potential energy as they build their own roller coasters from simple classroom materials.

NGSS Performance Expectations:
MS-PS3-2.
Develop a model to describe that when the arrangement of objects interacting at a distance changes, different amounts of potential energy are stored in the system.
MS-PS3-5.
Construct, use, and present arguments to support the claim that when the kinetic energy of an object changes, energy is transferred to or from the object.
Do your students have their own online accounts like email or social media? What about a login for the school computers? If so, they might have to pick passwords. Have you ever had trouble creating (and forgetting) good passwords? This fun lesson plan involves a guessing game that can teach your students how to make their passwords harder to guess. Learn how to keep your accounts safe!

We are surrounded by sounds every day, ranging from unpleasant ones like traffic noise to enjoyable ones like music or singing birds. What makes these sounds different? Why are some louder or higher pitched than others? In this lesson plan, your students will investigate how the properties of a sound wave, like frequency and amplitude, affect the sounds we hear. They will do this using Google's Science Journal app and a homemade musical instrument—a rubber band guitar!

NGSS Performance Expectations:
MS-PS4-1. Use mathematical representations to describe a simple model for waves that includes how the amplitude of a wave is related to the energy in a wave.
Learn about potential and kinetic energy the fun way—by launching ping pong balls across the classroom with a catapult!

MS-PS3-5. Construct, use, and present arguments to support the claim that when the kinetic energy of an object changes, energy is transferred to or from the object.
You might have read about the negative impacts modern human civilization has had on the environment, like pollution, deforestation, and extinction of animal species. How can we use modern technology to help protect the environment? In this project-based lesson students will design an electronic circuit that can measure something in the environment like water quality and light pollution, and develop a plan for how their circuits could be used to solve a real-world problem.

NGSS Performance Expectations:
HS-ESS3-4. Evaluate or refine a technological solution that reduces impacts of human activities on natural systems.
Your kindergarten students are used to moving objects. They throw balls, play with toy cars, and sweep the floor, but how much do they think about these actions? In this fun, hands-on lesson, you will use a game (rolling balls) to explore how pushing and pulling affects an object's motion.
This lesson can be expanded with a exploring how objects can push each other, and how weight influences motion.

NGSS Performance Expectations:
K-PS2-1.
Plan and conduct an investigation to compare the effects of different strengths or different directions of pushes and pulls on the motion of an object.
Don't just teach your students about Newton's laws of motion using diagrams in a textbook — try something hands-on! In this project, students will build their own cars using craft materials and explore the relationship between force, mass, and acceleration. Students can graph data and make observations in real-time using Google's Science Journal app or use a low-tech approach with a meter stick and stopwatch.

NGSS Performance Expectations:
MS-PS2-2. Plan an investigation to provide evidence that the change in an object’s motion depends on the sum of the forces on the object and the mass of the object.
Experimenting with balls is fun! In this hands-on lesson, you and your students will make them collide and study how balls can push each-other and people too! While exploring, students will also feel how pushing a light ball is different from pushing a heavier ball. Weight is important.
This lesson fits well together with a where students push balls to discover how people use pushes and pulls to change motion.
