Two activities explore the concept of size, especially small sizes down to the nano. Scholars practice determining volume, mass, and density and calculate exponential increases and decreases. They then predict and test the effect of size...

High schoolers are able to identify the components of the cardio-vascular system. They are able to describe the way the heart works to pump the blood. Students are able to explain the function of the cardio-vascular system. They are...

In this nephron worksheet, students color the parts of the nephron and answer five questions about the structures and functions of the parts of the nephron.

This plant structure and function PowerPoint addresses the main organs and the factors that affect its development as well as going into detail about the specializations at a cellular level.   The cell functions and system...

Students review the structure and function of DNA, genes, and chromosomes and are engaged by a demonstration illustrating the relative size of DNA, genes and chromosomes. They also describe through analogy and model the structure and...

Students discover how coroners use insect life cycles to estimate the time of death in cases. they describe how forensic entomologists combine environmental factors with insect life cycles to note the changes. Students examine an...

Adaptations must be made as environments change. This fabulous presentation features Icelandic icefish, a transparent, scaleless specimen that even has colorless blood. Genetics and adaptations concepts are explored as scientists study...

Junior geologists work through three mini-lessons that familiarize them with the formation and location of fossil fuels. Part one involves reading about petroleum and where it comes from via a thorough set of handouts. A lab activity...

Young water cycle enthusiasts discover the water they have been using has been cycling around the earth for billions of years. Through presentations, learners will understand that water has three states and how these forms...

The concept of a how pesticides and other chemicals pass through a watershed can be difficult for younger learners to grasp without a concrete example. In the activity here, some blank paper, markers, and a spray bottle are all you need...

Everything evolved from a common ancestor, but how did modern plants and animals develop so many more genes? Scholars use an online interactive to learn about the process. They begin to understand common genes with an animation, multiple...

Students plot earthquakes on a map. In this lesson on earthquakes, students will explore recent earthquake activity in California and Nevada. Students will plot fault lines and earthquake occurrences on a map.

Just because we can't see it doesn't mean it isn't there! A growing concern for environmental scientists is toxic nanoparticles in our air and water. Young scholars conduct an experiment to demonstrate how these particles can cross our...

Students solve the mystery of dead Mr. Potato Head using physics and algebra. They discuss Newton's Law of cooling as it applies to the mystery scenario involving a cooling baked potato as the "victim". They manipulate algebraic...

In this asteroids and planets worksheet, students read about the formation of planets from asteroids. Students solve 6 mathematical problems including finding the rate of growth of a planet, determining the mass of a planet at a given...

Students explore DNA microarrays. In this genetics lesson, students model DNA microarrays that are used by scientists. Students work to determine levels of breast cancer genes in patients. They will determine the treatment required based...

Learners, using 15 years of sunspot data, plot data on a classroom graph. They discuss why the pattern from their individual sheets did not and could not match the class graph.

Students research carnivorous plants and how they trap insects. They role play as botanists to write a research field guide about a newly discovered imaginary carnivorous plant.

Students explore lead poisoning and how it relates to ceramic dishes. They perform an experiment to discover if any of your ceramic ware is leaching lead which might cause lead poisoning.

Pupils explore the amount of lead in ceramic plates through an experiment. Students determine if everyday dishware is leaching lead into food. They chart their results and discuss how much lead in ceramic dishware may cause lead...

Learners explore the changes in the Sequoia forest ecosystem. They evaluate reasons for the changes and discuss opposing views of human activity, logging and fire management practices. Students observe a video, describe the location of...
