In this activity about gravity (page eight of the pdf), learners will very simply explore how gravity affects objects using balls and toys.

In this activity, learners build a sled kite that models a type of airfoil called a parawing.

Make a kite out of a garbage bag, shower curtain, painting tarp--anything light, thin, flexible and plastic!

This is a quick, yet dramatic activity/demonstration that introduces learners to the concept of energy transfer. A small ball is placed on top of a large ball and both are dropped together.

In this engineering activity (page 3 of PDF), young learners investigate how a pole can be made stable by “planting” its base in the ground or adding supports to the base.

In this activity (located at the top of the page), learners make an easy river strainer and see what they can catch.

In this activity, learners will explore the physics of liquids and gas by playing with both! Learners of any age use their own breath to move drops of water across a smooth wax paper surface.

In this fun physics activity (page 9 of the pdf), learners take part in a paper airplane design challenge.

In this activity, learners will explore how and why weight distribution works.

This is a great activity for investigating the basics of lift and drag as they pertain to flight. Learners will discover how to avoid "taking a nosedive" by building their own paper airplane.

In this hands-on activity, children create their own kites that can fly indoors. Learners are exposed to basic concepts of gravity and air resistance.

In this activity, learners discover how hard their hearts work to pump blood.

Make a copy of the first stethoscope with only a cardboard tube! René Laennec invented the first stethoscope in 1819 using an actual paper tube!

In this three part activity, learners explore and experiment with shadows to learn about the Sun's relative motion in the sky.

In this activity, learners model the flow of energy from the sun as it enters a photovoltaic cell, moves along a wire and powers a load.

In this activity, learners explore properties of water and watch evaporation happen by "painting" with water in the sun.

In this activity, learners participate in several full-body interactive games to model the process of self-assembly in nature and nanotechnology.

In this sunny day, outdoor activity, learners observe changes in shadows over time. The activity also helps to develop a sense of the Earth's motion.

In this activity, learners will observe how air interacts with a paper helicopter. Learners will test different variables of weight, size, and shape.

Use the Zoo Calendar (page 1 of PDF) to involve learners in interdisciplinary, whole language, and writing activities about ecological concepts.
