While the instructional activity focuses on right triangles, this activity offers a great way to practice the area of all triangles through an interactive webpage. The activity begins with the class taking a square paper and cutting in...

It's always nice to have a plan B. Pupils investigate an alternate formula for the area of a triangle that uses sine. A set of challenge questions shows how the new formula relates to the well-known formula of (1/2)bh.

Teams must determine the size of cavern needed to house the citizens of Alabraska to protect them from the asteroid impact. Using scaling properties, teams first determining the number of people that could sleep in a classroom and then...

Students identify the radius and diameter of a circle. In this geometry activity, students calculate the volume and area of a cylinder and circle. They relate the circumference of a circle to Pi.

Students explore eight career and technical areas and make connections with business, family and consumers, and technology. They examine and describe how agriculture and natural resources impact our quality of life. They explore and...

Young scholars investigate acoustical ceilings.  In this acoustical ceilings lesson, students construct a blueprint for an acoustical ceiling.  Young scholars use area and perimeter of rectangles to construct their...

How are raptors and airplanes alike? Combine science and language arts in this fun and interactive project. Young scientists research the animal in order to design their own aircraft, and compete in a contest for farthest, fastest, and...

Two activities are included in this resource. In the first, junior geologists model sedimentary rock layers, apply the Law of Superposition, and demonstrate folding and faulting of the Earth's crust. The model is technically a sandwich....

Building a doghouse is easier with a little mathematical help! Young scholars use sliders to adjust the length of the doghouse and watch as it affects the width and area. They then answer questions that help them discover the question...

A link to a comprehensive macroinvertebrate guide gives you the information needed to prepare for this field study activity. Sample macroinvertebrates are collected from areas representing different environmental conditions. Junior...

Class members connect engineering with an understanding of linear programming using a technical resource. Scholars learn about linear programming (linear optimization) and how it applies to engineering design in the first of two modules....

Build a soccer field through a little mathematical analysis. Individuals manipulate the dimensions of a soccer field as they drag points to new positions. The simulation shows the corresponding intercepts and area. As pupils explore the...

Flipped classrooms and online tools killed the chalkboard! An awesome, hands-on technology workshop asks teachers across all content areas. to examine model lessons, become familiar with research, and explore tech tools they can...

Sixth graders are introduced to the concepts of area and volume. In groups, they work together to build models of square centimeters in which they are given no instructions. To end the lesson, they record the dimensions of each model...

Explore the volume of solids with a real-life connection. Learners calculate the volume of a deep-dish slice of pizza to determine its price. They model the slice as a part of a cylinder and create a formula for calculating the cost.

Students explain what El Nino is, where it is located and how it is created. They describe the weather changes caused by El Nino. They draw the patterns of El Nino on a world map. They predict economic effects El Nino has on the areas it...

Students are introduced to Delaware's waterways as precious resources used for drinking water, water for agricultural and industrial uses, recreational areas, and as habitats for wildlife. They are introduced to wastewater discharges,...

Students examine abiotic and biotic factors. They define biotic and abiotic, categorize a list of items onto a Venn diagram, label various items from areas on the school grounds as biotic or abiotic, and diagram a magazine picture.

Students explore the components of a watershed and the factors that affect it. They read a topographical map and use geometry to determine the area of a watershed. Students estimate the volume of a body of water and perform runoff...

Students examine the characteristics of living things. They list the differences between living and non-living things, explore areas around the school, and create a Venn diagram for items found in the school areas.

Fifth graders explore nutrition by viewing video clips discussing world hunger. In this malnutrition lesson, 5th graders discuss the reasons people cannot afford food in rural areas and read assigned text discussing our agriculture...

Students explore food choices by researching the food pyramid in class. In this healthy eating habits lesson, students discuss each layer of the food pyramid and identify areas they need to improve in their own lives. Students visit the...

Students develop code systems to transmit information between groups. They explore, explain and apply techniques used to transmit remote sensing data to better understand remote sensing images.

Andree Walker thought of everything when he wrote this resource. It includes a detailed list of materials and background information links for the teacher. In addition, it has procedures, a macroinvertebrate identification key, and tally...
