ANEMOMETER FOR KIDS WINDOWS

The specific humidity is defined as the mass of water vapor in one kilogram of air. Evaporation contributes to water vapor in the air. Optional: waterproof paint, paint brushes and other materials to decorate their hygrometer.įigure 1.outside on a not too hot day), or drinking glass cooled by ice-cubes.

Optional: windows that face a colder area (e.g.

Wet sponge or small towel (either paper or cloth).

Resealable bag (large enough to fit the wood inside and have a little room to spare).

Two short nails (must be longer than the diameter of the straw).

Scrap piece of wood (about 25 cm long and 15 cm wide).

Glue (fast drying glue or a glue gun work best).

Drinking straw (preferably a wide, non-bending straw).

(strands from straight, wavy or curly hair are fine, frizzy hair makes it a little more difficult).

Two long strands of human hair (about 20 centimeters each), one to use and another as backup.

1 tsp rubbing alcohol (70% isopropyl alcohol works well).

Events that occur together with regularity might or might not be a cause and effect relationship. Scientists record patterns of the weather across different times and areas so that they can make predictions about what kind of weather might happen next.Ĭause and effect relationships are routinely identified, tested, and used to explain change. Use evidence (e.g., measurements, observations, patterns) to construct or support an explanation or design a solution to a problem.

This lesson focuses on these aspects of NGSS Three Dimensional Learning: Science & Engineering PracticesĬonstructing Explanations and Designing Solutions. Obtain and combine information to describe climates in different regions of the world. Represent data in tables and graphical displays to describe typical weather conditions expected during a particular season. This lesson helps students prepare for these Next Generation Science Standards Performance Expectations: Record qualitative humidity data taken with a hygrometer.Understand and give examples of processes that increase and decrease humidity.

Explain what humidity and evaporation of water are.A great way to make humidity visible! Learning Objectives What do a crazy hair day, a wooden door stuck in its frame, and the weather have in common? Humidity! In this fun hands-on weather lesson students explore surprising information about human hair, the air around them, and the weather by building a hygrometer from a strand of hair, a straw, a wooden panel, and two nails.
