Clay itself sinks, but clay boats float. Why? Young engineers build clay boats to learn about buoyancy. They test the weight the boats can hold using washers and then tweak their designs to make improvements, following the engineering...

Clay's as good a material as any to build a boat, right? An introductory lesson sets the stage for two activities associated with buoyancy. The first involves building boats out of clay, while the second uses these boats to measure the...

Students build a boat out of cardboard and tape. They apply Archimedes' Principle to their design.

Working in small groups students develop three alternative boat designs. They discuss the rationale for the type of hull, propeller, location of ballast, and type of building material used in their design. They build their boat.

Young scholars define the purpose of several different types of boats. They develop a list of materials one would ideally use in the construction of a particular type of boat. Students work cooperatively in a group to decide what type of...

Whatever floats your boat. Young engineers learn about density by measuring the masses and volumes of boxes filled with different materials. Using their knowledge of densities, they hypothesize whether objects with given densities will...

Build a scale model of a home built out of shipping containers. A hands-on activity has scholars watch a video about a home built from shipping containers and then design their own home. They build scale models of their designed homes...

Students build a boat and make predictions. In this geometry lesson, students design a cargo boat. They must show that the boat they designed can carry the cargo.

Building on young mathematicians' prior knowledge of three-sided shapes, this lesson series explores the defining characteristics of different types of triangles. Starting with a shared reading of the children's book The Greedy...

You've located buried treasure, now what? Explore how to use algebraic and geometric methods to determine where to place a recovery ship based on the location of the treasure.

Ancient Egyptian's had a fantastic number system and your class gets to use it to practice basic math skills! They are presented with several examples of Egyptian numbers which they use to complete several addition and subtraction...

Doubling a network or combining two networks is quick and easy when utilizing matrices. Learners continue the network example in the second lesson of this series. They practice adding, subtracting, and multiplying matrices by a scalar...

In this algebra worksheet, students solve 6 word problems. Problems include the necessary equations. Students solve 5 formulas by isolating the indicated variable.

In this right triangles worksheet, students use trigonometric ratios to determine the length of a side of a triangle or a missing angle measurement.  This two-page worksheet contains 20 problems.

In this angle measurement worksheet, 10th graders solve and complete 9 different word problems. First, they read the word problems carefully. Then, students draw a picture that represents each problem and solve. Finally, they find side...

Students experiment with common objects such as spools, string and soap to determine how pulleys make it easier to move large objects. They look at the difference between fixed and movable pulleys. They examine the many uses engineers...

In this angles of elevation and depression worksheet, 10th graders solve 6 word problems that include finding angles of elevation and depression. They solve each problem, rounding the measures of segments to the nearest hundredth and...

In this single step operations worksheet, students solve word problems. In his short answer worksheet, students write answers to eight problems.

This math lesson focuses on coins - specifically the nickel. Students use plastic nickles in order to gain practice counting by fives, and adding amounts of cents. Students complete a worksheet where they tally up different amounts of...

Second graders define "pound," estimate and compare weights, and classify objects as weighing more or less than a pound.

Students calculate their carbon footprint. In this environmental technology instructional activity, students listen to a lecture on climate change. Students brainstorm solutions to reduce environmental impact based on travel options....
