Sandwich Stratigraphy
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....

Bread Cells
Fifth graders examine plant and animal cells. In this plant and animal cell lesson, 5th graders define what cells are, label their parts, and describe how plant and animal cells are different. They observe cells at a number of web sites,...

What is an Aquifer?
Learners examine how an aquifer operates. They discuss the implications of the groundwater becoming contaminated. They work together to create an aquifer model to observe the connection between surface water and groundwater.
Curated OER
Jello Cells
Students create a three dimensional model of a cell. For this cellular structure lesson, students use gelatin, plastic bags, plastic containers, and fruit to construct a model of a cell. They compare the cells structures and stack them...

Bioaccumulation of Toxins
In 2015, Peter Cook found that sea lions with high levels of exposure to toxins suffered permanent brain damage if they survived at all. Scholars learn about the accumulation of toxins at various levels of the food chain. Using...

DNA/Genetics
Students delve into a study of DNA. In this science lesson plan, students gain an understanding of DNA, which is the genetic material for every person and every other living thing.
Curated OER
Necessary Nitrogen
Students view a video that presents the biogeochemical cycle of nitrogen. They compare types of soils and consider how different fertilizers affect soil composition.

Owl Pellet Lesson Plan
Students construct and identify a skeleton from the bones dissected from an owl pellet. They glue the bones on construction paper, label the page, and identify the animal.
Curated OER
The Colors of Nature
Students explore their outdoor environment, looking for varieties of color. Color samples from the outdoor environment are collected and used to create a sample page of colors that students label.
