In this activity about the baroreceptor reflex (BR) arc (page 123 of the PDF), learners discover the importance of maintaining adequate arterial blood pressure through a role playing exercise.

In this activity, learners predict where a ball will go after it bounces off another object. Learners discover that the motion of objects is predictable based on laws of motion.

In this activity about the brain and sleep (on page 138 of the PDF), learners measure their resting breathing rates. Learners will discover that breathing frequencies vary amongst individuals.

In this activity related to the human circulatory system (on page 10 of the PDF), learners observe the dispersion of a drop of food coloring in water, draw conclusions about the movement of dissolved

In this activity, learners pretend that they are orcas and search for their "pods" using Morse code.

In this activity, learners determine the shape of an unseen object by bouncing a ball off the object.

In this activity, learners investigate feeding relationships. Learners complete a food web and then make a mobile to represent a food chain.

In this math lesson, learners practice reading charts and graphs by creating and interpreting glyphs.

In this activity (on pages 22-24 of the PDF), learners match extreme enviroments with life forms they support.

In this activity, learners will examine various world data maps to combine the information and predict which areas could be tropical rainforests.

Computers store drawings, photographs, and other pictures using only numbers. Through this activity, learners decode numbers to create pictures using the same process that computers use.

In this activity, learners use information gathered from a variety of sources to design and make their own insect.

This fun and simple hands-on astronomy activity lets learners build a scale model of the universe with little more than adding machine tape.

In this activity about computer programming, learners follow instructions in a variety of ways in order to successfully draw figures.

In this activity about neuron/target muscle recognition (page 44 of the PDF), learners arranged in two rows facing away from each other use string to simulate neural development.

In this activity about humans and space travel (page 1 of PDF), learners compare and contrast the behavior of a water-filled plastic bag, both outside and inside of a container of water.

In this graphing exercise (page 2 of the pdf), learners compare their own height to the length of various sharks.

In this activity, learners build bridges using paper and explore how much weight each bridge design can support.

In this simulation activity, learners will raise a pack of wolves under ten different conditions: without human interference and with human interference.

In this computer science activity about finite-state automaton (on page 45 of the PDF), learners use a map and choose various pathways to find Treasure Island.
