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.
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.

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 second lesson 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.

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 lesson where students push balls to discover how people use pushes and pulls to change motion.

Teach your students how temperature affects chemical reaction rates in this highly visual experiment! Students will investigate color change during the reaction of food color with bleach, and measure the reaction times using Google's Science Journal app.

HS-PS1-5. Apply scientific principles and evidence to provide an explanation about the effects of changing the temperature or concentration of the reacting particles on the rate at which a reaction occurs.
How does surface area affect the speed of a chemical reaction? Let your students find out in this sizzling lesson plan! In this project, they will explore this correlation by crushing Alka-Seltzer® tablets into different sized particles and measuring how long it takes for them to dissolve in water.

Here is a challenge for your students: you need to send a number to someone on the other side of the classroom. The twist? You are not allowed to talk, write the number down, or use gestures or sign language! How would you do it? In this project, your students will explore different means of transmitting information by sending a message to a phone that can graph light, sound, and vibrations using Google's Science Journal app. They will learn about different sensors and interpreting graphs, and…
