In this self-measuring activity, learners observe and record how many times a minute they blink, take a breath, and chew, as well as how many times a minute their heart beats.

In this outdoor activity/field trip, learners explore the concept of population density.

In this outdoor activity, learners simulate an oil spill using popcorn (both oil and popcorn float on water), and estimate the spill's impact on the environment.

In this activity, learners build their own magnetometer using an empty soda bottle, magnets, laser pointer, and household objects.

In this outdoor activity, learners measure familiar objects in nature to practice working with the metric system.

Esta actividad enseña la proporción y razón por hacer que los aprendices hagan "ensaladas" que combinan tres tipos de frijoles en tres combinaciones diferentes.

In this outdoor activity, learners search for the warmest and coolest, windiest and calmest, wettest and driest, and brightest and darkest spots in an area.

In this outdoor activity, learners use only their senses to to find the extremes of several environmental variables or physical factors: wind, temperature, light, slope and moisture.

How do you measure a bubble when it's floating? You can't really, but in this activity, learners can measure the diameter of the ring of suds a bubble leaves on a flat surface.

In this outdoor activity, learners race small boats, made of cork, balsa wood, popsicle sticks etc., to investigate the rate and direction of currents in a stream or creek.

In this activity, learners make their own pinhole viewer in order to measure the size of the sun.

This game teaches ratio and proportion by having learners make "salads" that combine three types of beans in different combinations.

In this outdoor activity/field trip, learners conduct experiments to explore where dragonflies and damselflies perch or rest, and how the flies change behavior in reaction to other flies or fly decoys

In this outdoor activity, learners plan a simple foot path and create an environmental impact study of the natural area where the path would be.

In this outdoor activity/game, learners use thermometers to simulate how lizards survive in habitats with extreme temperatures.

In this fun sticker activity, learners will create a size wheel with images of objects of different size, from macroscopic scale (like an ant) to nanoscale (like DNA).

In this outdoor activity, learners saw sections from fallen trees, then count tree rings and look closely at patterns of tree growth.

How do scientists measure how clear or murky water in a lake is? How does water clarity (clearness) affect what lives in the lake?

In this highly physical outdoor activity, learners construct and compare experimental trail sections to select the best trail-construction technique for their site.
