Students brainstorm and discuss the different types of materials used to build houses in various climates. They build small models of houses and test them in different climates.

Students will construct CD hovercraft and apply Newton's laws of motion to make them work. They will also investigate how hovercraft reduce friction; learn how the technology is used in training astronauts for space missions; and design their own hovercraft competitions.

Students learn how to program using loops and switches. They see how loops enable us to easily and efficiently tell a computer to keep repeating an operation. They also see that switches permit programs to follow different instructions based on whether or not preconditions are fulfilled. Using the LEGO MINDSTORMS(TM) NXT robots, sensors and software, student pairs perform three mini programming activities using loops and switches individually, and then combined. With practice, they incorporate these tools into their programming skill sets in preparation for the associated activity. A PowerPoint® presentation, pre/post quizzes and worksheet are provided.

Building on the programming basics learned so far in the unit, students next learn how to program using sensors rather than by specifying exact durations. They start with an examination of algorithms and move to an understanding of conditional commands (until, then), which require the use of wait blocks. Working with the LEGO MINDSTORMS(TM) NXT robots and software, they learn about wait blocks and how to use them in conjunction with move blocks set with unlimited duration. To help with comprehension and prepare them for the associated activity programming challenges, volunteer students act out a maze demo and student groups conclude by programming LEGO robots to navigate a simple maze using wait block programming. A PowerPoint® presentation, a worksheet and pre/post quizzes are provided.

A lesson plan for 4th grade science. Kids create a version of the marble roll project to simulate a manufacturing process.

Objectives:
* Illustrate the problem of food waste in the United States.
* Inspire students to make conscious efforts to reduce their food waste.
* Use the mini food waste audit activity to demonstrate to students how they are contributing to the problem

Students are introduced to the basic principles behind engineering and the types of engineering while learning about a popular topic - the Olympics. The involvement of engineering in modern sports is amazing and pervasive. Students learn about the techniques of engineering problem solving, including brainstorming and the engineering design process. The importance of thinking out of the box is stressed through a discussion of the engineering required to build grand, often complex, Olympic event centers. Students review what they know about kinetic and potential energy as they investigate the design of energy-absorbing materials, relating this to the design of lighter, faster and stronger sporting equipment to improve athletic performance and protect athletes. Students consider states of matter and material properties as they see the role of chemical engineering in the Olympics. Students also learn about transportation and the environment, the relationship between architecture and environment, and the relationship between architecture and engineering.

In this activity, students will learn to identify different opinions related to an issue as well as the things (information, values and beliefs) that influence those opinions. They will use an opinion spectrum to analyze the range of opinions in their classroom on environmental issues and understand how these spectrums can be valuable to engineering design.

In this activity, students filter different substances through a plastic window screen, different sized hardware cloth and poultry netting. Their model shows how the thickness of a filter in the kidney is imperative in deciding what will be filtered out and what will stay within the blood stream.

The purpose of this activity is to demonstrate how aircrafts have decreased the amount of time it takes to transport people and cargo. Students will compute the time it takes to travel between two cities for several modes of transportation including trucks, trains and airplanes. Students will also do some critical thinking to determine why airplanes are not always used.

Learn how to make a water filter using materials from around your home or classroom.

Student groups are challenged to program robots with light sensors to follow a black line. Learning both the logic and skills behind programming robots for this challenge helps students improve their understanding of how robots "think" and widens their appreciation for the complexity involved in programming LEGO® MINDSTORMS® NXT robots to do what appears to be a simple task. They test their ideas for approaches to solve the problem and ultimately learn a (provided) working programming solution. They think of real-world applications for line-follower robots that use sensor input. A PowerPoint® presentation and pre/post quizzes are provided.

After reading the story "Dear Mr. Henshaw" by Beverly Cleary, student groups create alarm systems to protect something in the classroom, just as the main character Leigh does to protect his lunchbox from thieves. Students learn about alarms and use their creativity to devise multi-step alarm systems to protect their lockers, desk, pets or classroom door. Note: This activity can also be done without reading the Cleary book.

In this solar oven lesson plan, students will learn about renewable energy by constructing their own solar ovens using simple materials like cardboard boxes, aluminum foil, and plastic wrap. They will explore the science behind solar energy, including how sunlight can be converted into heat energy to cook food. The activity will involve assembling the ovens, placing food items like s'mores inside, and observing the cooking process under direct sunlight. Through hands-on experimentation, students will gain an understanding of the environmental benefits of solar energy and its practical applications.

In this engaging lesson plan, students will dive into the principles of engineering and structural design as they construct spaghetti bridges. They will learn basic principles of structure and stability while working in teams to design and build their bridges using simple materials. Through a fun and friendly contest, students will test their creations to see which bridge can hold the most weight. This hands-on activity promotes teamwork, creativity, and problem-solving skills in a playful and educational environment suitable for young learners.

The basic processes involved in manufacturing systems are demonstrated while students produce their own picture frames. They learn about cutting, shaping, assembly, joining and finishing, as well as attention to quality, safety and production quantity.

Students design, build and test model race cars made from simple materials (lifesaver-shaped candies, plastic drinking straws, Popsicle sticks, index cards, tape) as a way to explore independent, dependent and control variables. They measure the changes in distance travelled with the addition of mass to the vehicles. Students also practice the steps of the engineering design process by brainstorming, planning, building, testing, and improving their "mint-mobiles."

To ceIebrate Earth Day, students investigate solutions they can take to support climate action. Then, students share this information by creating a #MyPlanetMyPledge sign. Suitable for all grade levels.
