When the sun's rays can't reach the producers in a food web, where does all the energy come from? Extreme environments call for extreme food sources. Young scientists investigate creatures that appear to get their energy from methane...

How can you launch an object that isn't propelled by air? The resource provides directions to build a launcher to launch rockets made of two-liter bottles. The launcher, built mainly from materials found at the local hardware...

Apply, apply, apply! A measurement lesson applies a number of concepts to help learn a new construction. Scholars learn to divide a segment into n equal parts using a method that uses the Side Splitter Theorem and a method that...

Explore constructions through an interactive online lesson. Given an example of an angle bisector construction, learners investigate the markings to determine the method used. Challenge questions help solidify the steps. 

Explore angle relationships associated with transversals. Pupils construct parallel lines with a transversal and find the measures of the angles formed. They figure out how the different angles are related before constructing...

What better way to study survey design than to design your own survey! Bring a versatile data analysis project to your AP Statistics class, and encourage them to apply the practices from their instructions to a real-world survey...

Will that structure survive the force? The differentiated lesson allows pairs to choose the structure they would like to construct and the building materials they wish to use. Individuals record their findings in...

Groups plan their escape carefully. Three three-tiered puzzles help a story character escape their situation, each involving integer sequences, transformations, and geometric constructions. The teacher resource includes...

 A short assessment asks participants to find the original radius required to replace a table top. The problem provides a hypothetical situation of having a segment of a broken glass table top. Pupils find the radius of the...

What does viscosity have to do with splatter? An activity shows that the viscosity of a substance is inversely proportional to the distance of its splatter. Learners conduct the experiment by collecting data, graphing, and analyzing...

How much does the sun heat up a lake or ocean? Scholars use a cup and a strong lamp to investigate the heat transfer and thermal layers in the ocean to come up with the answer. They collect data and graph it in order to better understand...

How do scientists know what Earth's climate was like millions of years ago? Young environmental scholars discover how researchers used proxy data to determine the conditions present before written record. Grouped pupils gain experience...

Create bending joints—but don't break! The activity shows how to make a puppet using straws and fishing line. Pupils create cuts to make joints that rely on the elasticity of the straw to bend and return to their original shapes.

Your learners connect the new concepts of transformations in the coordinate plane to their previous knowledge using the solid vocabulary development in this unit. Like a foreign language, mathematics has its own set of vocabulary terms...

Learn about the characters of Natalie Babbitt's Tuck Everlasting with a character biopoem. Readers fill in a poem format to detail the character traits of Winnie, Jesse, Miles, and Mae, and share their finished poems...

Investigate polygons from rectangles to triangles to octagons. Each level of the five-problem series targets a different grade level. Beginning with the level A problem, learners examine the relationship between area and perimeter by...

Put your heart into it. Scholars design and build replacements for mitral heart valves. Obviously, they can't test their creations on a real heart, so a box with marbles (to represent blood cells) will suffice.

It is hard to determine whether there is a relationship with the categorical data, because the numbers are so different. Working with a familiar two-way table on super powers, the class determines relative frequencies for each...

Rainwater doesn't stay where it falls. Learners use modeling to demonstrate how rainwater disperses once it hits the ground. The activity includes an investigation of the height of the water table in an aquifer and how it is affected by...

Leaf by Leaf: Autumn Poems by Barbara Rogasky is the foundation of this lesson plan on theme identification. Critical thinkers read three different poems from the book then attempt to find the message the author is sending her readers....

Don't just teach learners to fish, but to create fish. The class discusses fish heads and predicts whether where the fish might live and what it eats. Given an index card with a fish adaptation written on it, pupils construct an...

This creative cut and paste activity requires learners to identify the colors red, brown, green and orange, as well as follow directions. Students color a group of shapes, and following the directions, paste each piece onto a sheet of...

Develop novice script-writers. Small groups sift through a sample script, noting any script-writing conventions to share with the whole class. Using these conventions and plot structures, these groups compose a script for a 10-minute...

Help bring subconscious stereotypes to the surface to stop it in its tracks. Pupils first read an excerpt describing the experience of prejudice and analyze how this process connects to World War II. Then, they write a creative story...
