Seed Selection for Genetic Variation
Students will research the origin of corn, analyze factors that contribute to shorter and longer growing seasons, and use the scientific method to answer the question: Did seed selection contribute to the successful movement of corn from...
Curated OER
Steppin' Out
Students are presented with the question: "Do longer legged people run faster than shorter legged people?" Students conduct an experiment, collect their data, create box and whisker plots using a computer and graphing program, and...
Curated OER
In a Giants Garden
Learners explore the effect of the earths rotation and its relationship to the suns position and the effect that the longer and shorter amount of daylight has on a pumpkin plant which they have planted.
Curated OER
Structural Geology Laboratory
Young scholars explore modeling of geologic structures in experiments. They study how compressive and tensile forces produce these structures. The compression makes the flatlying strata shorter and tension make the strata longer.
Curated OER
Special Right Triangles
Using the Pythagorean Theorem to solve for missing angles, young scholars evaluate right triangles and their properties.

Outbreak: Infection Detection
Explore the mathematics of infection outbreaks with activities that ask learners to use coordinate grids to locate infected patients. They calculate amounts of ingredients for antidotes and determine which groups of people should be...
Curated OER
Investigating Leaves Through Printmaking
Students create leaf rubbings as they study the parts of a leaf. They describe the leaves and chart their observations.
Curated OER
Counting Sentences' Words
Explore language arts by completing a worksheet with class. They read the story Owl Moon and discuss the rhythm of the writing and how action verbs are used appropriately. Then complete a writing worksheet which discusses writing...

Step Into My Shoes
Students order their classmates from smallest to largest foot length. In this ordering their classmates from smallest to largest foot length lesson, students trace each of their classmates foot. Students read a story called, 'How Big...
Curated OER
Classification and Identification
Young scholars, after exploring and analyzing diagrammatic and taxonomic keys and their association to marine sciences, identify and classify objects and organisms based on visual attributes/characteristics. They research and create...
Curated OER
This Is a Stick Up
Learners create a sundial and track the movement of the sun throughout the day. Modifications to the lesson are provided for both lower and upper elementary students.
Curated OER
Reading Fiction: Analyzing Sentences
Students investigate sentence construction in fiction. In this sentence construction lesson, students examine examples of fiction work and discover why sentences are a certain length. Students create their own passages playing with...
