The Hudson's Ups and Downs
Even rivers have tides. Older elementary schoolers will discuss the Hudson River and how weather, water craft, and the ocean cause tidal fluctuation. They will examine a series of line graphs that depict tidal fluctuation, then analyze...
Curated OER
Chain Across the Hudson
Fourth graders role play as contractors responsible for constructing a chain across the Hudson River. They apply math skills to determine the total weight, number of links, and cost of the project.
Curated OER
Weather Patterns
Students use yearly averages over a five-year period to understand weather trends for a specific area.
Curated OER
Rover Races
Students identify the challenges encountered by astronauts in operating a planetary rover. In this space science lesson, students create a rover using their team members. They follow a command sequence from the driver and navigate...
Curated OER
One, Two, Three...and They're Off
Students make origami frogs to race. After the race they measure the distance raced, collect the data, enter it into a chart. They then find the mean, median, and mode of the data. Next, students enter this data into Excel at which time...

Teaching and Learning Through Objects
Students identify and interpret the function, usefulness or utitlity, form, beauty or aesthetics, and meaning, context or story, of objects and how they learn new skills and make things that they learn traditionally, by observation and...
Curated OER
Concept Structures in Architecture
Students develop a creative building design. In this technology lesson, students create a model of their building using a computer software. They present their final product in class.
Curated OER
Discovering Friction
Students watch a demonstration that introduces them to the idea that friction is a force that impedes motion when two surfaces are in contact. They work in groups to experiment with frictional force using a coffee cup on which they alter...

Populations Lab - Exponential Graphing
Ninth graders investigate the application of populations that exists in one's everyday environment, in order to develop an understanding of how mathematics is a key component in the understanding of population dynamics.
Curated OER
Look at Those Leaves!
Young scholars observe leaves. In this math and science cross-curriculum leaf lesson, students take a nature walk and collect leaves. Attributes are assigned and leaves are sorted in various ways. Young scholars use non-standard or...

Create Your Save and Rave Box
Second graders use empty pizza boxes and pattern blocks to create a Save and Rave Box, which is a 3-D portfolio.
Curated OER
Take Me Out To the Ball Game
Students use a map to graph and locate major league teams of different sports. In groups, they analyze the population data of the United States and compare it with the amount and location of the major league teams. They share their...

Designing a Spectroscopy Mission
In this mind-bending activity, young engineers explore this question of whether or not light actually bends. Using holographic diffraction gratings, groups design and build a spectrograph. The groups then move on research a problem...
Curated OER
Urban Changes
Students explore how landscapes undergo constant changes with urban development. They plan and build their own "city" by including features that have minimal resource demands to sustain the city itself.
Curated OER
Copy Cat
Students examine a Webmath page, and demonstrate how to copy and paste. They create a computer-generated template page presenting the attributes of two- and three- dimensional shapes.

Let's Tesselate
Learners investigate the geometrical concepts of translation, reflection, and rotation. They make different observations looking for the concepts that are displayed in classroom items like floor tiles, carpet designs, and visuals hung in...
Curated OER
Topos, Compasses, and Triangles, Oh My!
Young scholars triangulate using a compass, topographical (topo) map and a view of outside landmarks. They take a field trip to another location away from school and mark discernible landmarks (like mountains or radio towers) and changes...
