"Compost" © 2014 Philip Cohen In this two-part inquiry-based activity, students will practice using the scientific method while learning about decomposition, exploring how some types of garbage will decompose while others will not. Students can then go on to design their own experiment to test different variables affecting the rate of decomposition. Read more

NGSS Performance Expectations:

5-LS2-1. Develop a model to describe the movement of matter among plants, animals, decomposers, and the environment.

Cricket Wicket Knockdown Challenge for Grades 6-8

Lesson Plan Grade: 6th-8th

Teach your students about the engineering design process with this fun lesson plan. They will design and build a ball-launching machine to knock down a target. Optionally, they can enter their designs in the 2020 Engineering Challenge for a chance to win a cash prize for your school! Teachers, note that elementary school and high school versions of this lesson plan are also available. Read more

NGSS Performance Expectations:

MS-ETS1-2. Evaluate competing design solutions using a systematic process to determine how well they meet the criteria and constraints of the problem.
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.
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.

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.

In this lesson, students are challenged to design and build a controlled-release tablet, which will be made from different colored bath tablets and a variety of water-soluble plastics. First, they will have to test the properties of each of the different plastic materials. Then their task will be to create a tablet that releases three different colors, each at a pre-determined time after the tablet has been submerged in water. As students design and build their controlled-release tablets, they… Read more

NGSS Performance Expectations:

MS-PS1-2. Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred.
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.

Forests are the green lung of the Earth and home to millions of different plant, fungi, animal, and bacteria species. Unfortunately, today many forests are threatened by deforestation, which causes significant biodiversity loss. Ongoing reforestation efforts across the world intend to counteract the effects of deforestation. As planting trees by hand does not scale well, machines on the ground, as well as flying drones have been developed to help plant tree seedlings or seeds. In this lesson,… Read more

NGSS Performance Expectations:

MS-LS2-5. Evaluate competing design solutions for maintaining biodiversity and ecosystem services.
MS-ETS1-2. Evaluate competing design solutions using a systematic process to determine how well they meet the criteria and constraints of a problem.
MS-ESS3-5. Ask questions to clarify evidence of the factors that have caused the rise in global temperatures over the past century.

Digital Photos and Dynamic Range

Science Fair Project Idea

Scientific Method

Digital cameras can be a great way to learn about photography. Most digital cameras today have LCD screens, so you get instant feedback on your photo. If you make a mistake, no problem, you just delete the picture. It's nice that you don't have to worry about the expense and bother of developing film! This project can help you learn to take better pictures. Read more

Each student will get the chance to identify their own uniquely interesting STEM careers by tapping into the insights of the Career Discovery Tool. Remote learning adaptation: This lesson plan can be conducted remotely. During the Engage section, students can "order" their favorite ice cream using a poll on video chat. During the Explore section, students can access the Career Discovery Tool remotely as long as they have a device and access to the Internet. They can complete the Explore… Read more

Divide and Conquer: Proving Pick's Theorem for Lattice Polygons

Science Fair Project Idea

Scientific Method

If you like to play Tetris, then you might like this project. You will learn something interesting about the mathematics of complex shapes as you try to prove Pick's Theorem. The strange shape below is an example of a lattice polygon, which is a polygon whose vertices lie on points in the plane that have integer coordinates. As you can see, it is a complex shape, but there is an easy way to calculate its area, by simply counting lattice points! If you count the number of lattice points on… Read more

To slow the spread of COVID-19, the CDC recommends wearing a mask or cloth face covering—particularly in places where it is impossible to maintain social distancing (staying at least 6 feet away from others). This recommendation is for everyone age two or older (children under the age of two should not wear masks). Many instructions to make your own mask are available online. This activity will help you think through the process of designing and making a mask as an engineering problem.… Read more

Most modern smartphones and video game controllers have a built-in accelerometer used for motion control. In this project you will program an Arduino® to use an accelerometer to control the steering of a miniature popsicle stick drone. See this page for a complete list of our mini drone projects. You may wish to do the projects in order. Read more
