Strive for perfection. Based on peer feedback, groups identify ways to improve their prototypes of the solution to the plastics problem. Members must come up with at least two ideas for improvements. This is the eighth instructional...

High school classes can use manipulatives too! Offer hands-on, interactive lessons that venture away from the typical day in your algebra class. Young mathematicians will be involved in collaborative learning, visual...

This is a comprehensive lesson on creating and solving equations and systems of equations and inequalities. Problems range from basic linear equations to more complex systems of equations and inequalities based on a real-world examples....

Learn to code, play, then repeat. The fourth of nine installments in the Intro to CS with MakeCode unit focuses on how to apply iterations in Minecraft. Scholars use the Agent feature and have it dance and build a farm.

Let's go fly a kite ... oops, a paper airplane! The 13th segment in an aviation unit of 22 relates the parts of an airplane to paper airplanes. Pupils learn the functions of the control surfaces of a plane to really make their knowledge...

Groups work together to design a lighthouse, from designing and drawing the wiring diagram, to creating prototypes of the switch and circuit, to envisioning and building a scale model along with a blueprint. By including different...

Students investigate the concepts of area and perimeter with the use of chocolate bars. They calculate the perimeter and area of different size rectangle chocolate bars and record the statistics. Then students make a visual comparison...

In this numerical analysis worksheet, students solve systems of non-linear equations. Examples and explanation are provided. This two-page worksheet contains approximately three problems.

Tiny particles can provide big learning opportunities! Middle school scientists explore the world of nanoparticles through reading, discussion, and experiment. Collaborative groups first apply nanotechnology to determine water...

Enough with the talking, let's build something! In the fifth step in the engineering design process, young engineers build a prototype to test their ideas. The activity walks them through the process of evaluating it step-by-step....

Take a look at linear functions in a new environment. A three-stage algebra project first asks learners to model the salt concentration of an aquarium using linear functions. Then, using iterations, pupils create a set of input-output...

Need a activity? Problem solved. Scholars learn about the problem-solving process in the sixth installment of a 25-part Energy Systems and Solutions unit. The particular process in question is the Technological Method of Problem Solving.

Collect a set of collections. Professional development material provides teachers with information about collections that are in AP Computer Science. Materials include teaching strategies, sample labs, and worksheets. Educators use the...

Once your geometers know how to apply the formula V = l w h, they will be ready to take on the fractional volume of a fish tank. Have your number crunchers swap heights so they can see that the fractional volume will not change. 

There are a billion reasons to use the resource! Well, not quite. A demonstration using food color and water shows scholars the meaning of nano. An iterative process results in diluting the concentration of food coloring by one tenth...

Students solve exponential functions and inequalities. In this algebra lesson, students find the roots of equations and use it to graph and evaluate exponential functions. They simplify exponents using the law of exponents.

Compound machines, nothing more than a combination of simple machines working together, are the focus of an activity that asks class members to use the provided information to take a look at the way innovators combine simple machines to...

Second graders identify the hour and minute hands. They tell time by the hour, nearest quarter hour, half hour, and determine the relationships of time (e.g. minutes in hour, days in a month, weeks in a year). They create over-sized...

Young scholars practice measuring items with non standard units. In this units lesson plan, students measure shapes, lengths, and classroom objects.

Don't drop the ball on the resource ... drop an egg instead! A teacher-led demonstration has the class consider how to drop eggs into glasses when a tray is in the way. Hint: If you've ever seen a magician pull a tablecloth off a table,...

Concentrate to determine the best reflector design. Pairs use the engineering design process to build a reflector to increase the current output of a photovotaic panel. Teams arrive at a final design and present it to the class along...

Boxing takes on a whole new meaning! The second installment of the three-part series has groups create lidless boxes from construction paper that can hold the most rice. After testing out their constructions, they build a new box....

Kids will compare creating fractions from pieces of paper to chips. They begin with a fractional part and work back to a whole. Then order fractions from smallest to largest. They also complete a worksheet to find the missing pieces to...

The engineering design process meets laparoscopic surgical robots with an activity that is the last part in a series of 10 and brings all the lessons of the unit together. Teams design and build a remotely controlled laparoscopic device....
