In this Biodiversity Counts activity, students create their own aerial insect net using common and inexpensive supplies: net fabric, a coat hanger, a wooden handle, duct tape, a sewing needle, and thread. The online activity page includes illustrated step-by-step directions and a brief introduction to the use of fabric nets.

This Biodiversity Counts illustration shows students how to make a simple killing jar to preserve arthropods for further study. As the labeled drawing shows, all that's needed is a jar with a lid, tape for reinforcement, a few drops of ethyl acetate, and a paper towel.

In this Biodiversity Counts article, students learn how to preserve their plant pressings.

In this Biodiversity Counts activity, students learn how to press and preserve plant specimens. The online page includes illustrated instructions about how to layer and maintain pressings until the specimens have dried.

In this Biodiversity Counts activity, students learn how to replicate an arthropod's natural habitat in order to create suitable guest quarters. The online page includes instructions for what to observe in an arthropod's environment, tips for converting a container, such as a soda bottle or aquarium, into a hospitable habitat with plenty of oxygen, water, hiding places, and other arthropod necessities, notes about what to feed the arthropod and where to purchase both arthropods and their food.

In this Biodiversity Counts activity, students learn how to set up a Berlese funnel and coax tiny arthropods out of their habitat for further study. The page includes a labeled illustration.

In this Biodiversity Counts activity, students learn how to set up a yellow pan trap to attract insects drawn to the color yellow. The supplies required are readily available.

In this Biodiversity Counts activity, students learn how to create and set up a pitfall trap to catch soil dwellers. The online activity page includes easy-to-follow directions for building a trap with recycled plastic containers, stones, wood/cardboard, and a bait of the students' choosing. Students let the trap sit either for a few hours or overnight to see what they have caught. To expand their investigation, students are challenged to experiment with different baits to see if they can attract different arthropods.

This online article, from Biodiversity Counts, is a general-purpose tip sheet for using a dichotomous key. The article outlines a three step process using a tree as an example.

This site assembles the information from the April 1997 American Museum of Natural History symposium on the role humans have played, and continue to play, in the extinction of species. It presents an overview of extinction, the various hypotheses that explain this irreplaceable loss, details about what happened 14,000 years ago and the ongoing role humans play in the extinction process, a bestiary with notes and illustrations about some of the mammals that have gone extinct from the Pleistocene era through the 20th century, and what can be done to prevent another extinction event.

Map of Africa coded by the number of underweight children per square kilometer. It is thus a measure of the absolute density of hungry individuals, a combination of hunger and population density.

Map of Asia color coded by infant mortality rate broken down by nation or subnational units (akin to US states or Canadian provinces). Shows the international differences, but also shows the (less substantial) differences within nations. The categories for the color coding have been changed slightly from the international standards to better fit the situation in Asia.

Map of Europe color coded by infant mortality rate broken down by nation or subnational units (akin to US states or Canadian provinces). Shows the international differences, but also shows the (less substantial) differences within nations. The categories for the color coding have been changed from the international standards to differentiate among the universally low infant mortality rates across Europe.

This is a Project Based Learning lesson plan created for a first grade classroom. In this lesson plan students will use hands on activities to learn about the differences of animal environments and why they differ from one another.

This representation is a cut-away sketch showing select body organs and cells of a young person throwing a basketball. Close-up views of heart muscle cells, blood cells, small intestine cells, and nerve cells are shown. Supporting text accompanies the sketch.

KiteModeler was developed in an effort to foster hands-on, inquiry-based learning in science and math. KiteModeler is a simulator that models the design, trimming, and flight of a kite. The program works in three modes: Design Mode, Trim Mode, or Flight Mode. In the Design Mode (shown below), you pick from five basic types of kite designs. You can then change design variables including the length and width of various sections of the kite. You can also select different materials for each component. When you have a design that you like, you switch to the Trim Mode where you set the length of the bridle string and tail and the location of the knot attaching the bridle to the control line. Based on your inputs, the program computes the center of gravity and pressure, the magnitude of the aerodynamic forces and the weight, and determines the stability of your kite. With a stable kite design, you are ready for Flight Mode. In Flight Mode you set the wind speed and the length of control line. The program then computes the sag of the line caused by the weight of the string and the height and distance that your kite would fly. Using all three modes, you can investigate how a kite flies, and the factors that affect its performance.

In Part I of this hands-on, minds-on activity, students investigate the effects of hypotonic and hypertonic solutions on eggs. Students interpret their results and develop a basic molecular understanding of the process of osmosis. In Part II, analysis and discussion questions guide students as they further develop their understanding of osmosis and apply this understanding to the interpretation of several “real-world” phenomena. This activity is aligned with the Next Generation Science Standards.

The microscopic world is full of phenomena very different from what we see in everyday life. Some of those phenomena can only be explained using quantum mechanics. This activity introduces basic quantum mechanics concepts about electrons that are essential to understanding modern and future technology, especially nanotechnology. Start by exploring probability distribution, then discover the behavior of electrons with a series of simulations.
