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.
Have you or your students ever felt frustrated at not being able to access a favorite website or online game? Did you realize the site might have been a victim of a cyber-attack? If you aren't careful about online security, your own computer could even be used to launch the attack! In this fun lesson plan, you and your students will model one type of attack (a denial-of-service attack) and figure out how to protect the network against it (no computer programming required)!

NGSS Performance Expectations:
MS-ETS1-3. Analyze data from tests to determine similarities and differences among several design solutions to identify the best characteristics of each that can be combined into a new solution to better meet the criteria for success.
MS-ETS1-4. Develop a model to generate data for iterative testing and modification of a proposed object, tool, or process such that an optimal design can be achieved.
Are paper airplanes a nuisance in your classroom? They don't have to be! Those distractions can be a constructive learning opportunity: use them to teach your students about the engineering design process. In this fun lesson, you will be the "customer" ordering a paper airplane, and your student teams will be engineering companies that will manufacture planes. Before they start making planes, they need to define the criteria and constraints of this engineering problem.

3-5-ETS1-1. Define a simple design problem reflecting a need or a want that includes specified criteria for success and constraints on materials, time, or cost.
If you love doing arts and crafts with your students, this lesson plan is for you! Teach them about energy, electricity, and circuits as they build light-up sculptures, using something they are all familiar with—play dough! Clear step-by-step instructions are provided and no previous experience with circuits is required.

NGSS Performance Expectations:
4-PS3-2. Make observations to provide evidence that energy can be transferred from place to place by sound, light, heat, and electric currents.
Does human activity impact the environment? If so, how can we measure our impact on the environment? How can we use these measurements to change our behavior? In this project, your students will explore these questions by designing and building an electronic circuit that can measure environmental parameters like water quality or light pollution.

NGSS Performance Expectations:
MS-ESS3-3. Apply scientific principles to design a method for monitoring and minimizing a human impact on the environment.
How does our body fight an infection when we get sick? In this lesson, students will build a model of our immune system to find out how our body responds to invading bacteria or viruses that cause diseases and to investigate the role of memory cells.

NGSS Performance Expectations:
MS-LS1-3. Use argument supported by evidence for how the body is a system of interacting subsystems composed of groups of cells.
Do your students think making things float in mid-air is a magic trick? Show them how you can do it with science! In this lesson plan they will learn about interactions between magnets and figure out how to make them float.

NGSS Performance Expectations:
3-PS2-3.
Ask questions to determine cause and effect relationships of electric or magnetic interactions between two objects not in contact with each other.
How is it possible that our eyes can see things that are not really there? In this fun lesson plan, your students will explore how our vision works with the help of two short experiments that involve some fascinating optical illusions. Let your students discuss why they see a hole in their hand, or why they see colors that were never there, and let them construct their own explanations.

NGSS Performance Expectations:
MS-LS1-8.
Gather and synthesize information that sensory receptors respond to stimuli by sending messages to the brain for immediate behavior or storage as memories.
In this fun lesson plan, students will measure how the amount of carbon dioxide in their exhaled breath changes with exercise levels. Carbon dioxide is a product of cellular respiration, so the lesson highlights how breathing is connected to cellular respiration and energy production in our body. They will make the measurements using a simple colorimetric test and a phone with Google's Science Journal app.

NGSS Performance Expectations:
MS-LS1-7. Develop a model to describe how food is rearranged through chemical reactions forming new molecules that support growth and/or release energy as this matter moves through an organism.
Explore genetic variation through the world of taste in this problem-solving lesson plan. Working both individually and collaboratively, students figure out what kind of tasters they are, what this means about their own genetics, and how genetic mutations can lead to functional differences. This activity provides a hands-on, personalized opportunity to learn about how genotypes and phenotypes align.

NGSS Performance Expectations:
MS-LS3-1. Develop and use a model to describe why structural changes to genes (mutations) located on chromosomes may affect proteins and may result in harmful, beneficial, or neutral effects to the structure and function of the organism.
MS-LS3-2. Develop and use a model to describe why asexual reproduction results in offspring with identical genetic information and sexual reproduction results in offspring with genetic variation.
Kindergarten students associate the sun with light and warmth. This lesson helps them expand this knowledge by getting their hands dirty! They will fill cups with soil, water and rocks and place them in the sun and shade for a while. By finding out how they can tell where a cup has been stored, they will learn how the sun affects Earth's surface.
In a follow-up lesson, , students figure out how to protect a territory from getting too hot in the sun.
