A teacher should have reasonable expectations of how long young children can be attentive in certain areas and should know how to supervise and balance  these activities.

Puppets, to be used in the early childhood classroom, may include stick puppets, bag puppets,  hand puppets, finger puppets, wooden spoon puppets, or even puppets made from paper plates, socks, gloves, mittens, cardboard, styrofoam balls, or other materials. 

Young children learn important concepts such as “hard” and “soft” and “same” and “different” through artwork.

Which of the following are health effects associated with exposure to air pollution? 

Which act is responsible for regulating the discharge of pollutants in our waters and the quality of surface water in United States ?

A surface has a hemispherical, spectral emissivity of 0.3 from 0 to 3 µm and 0.8 from 3 µm to infinity. If the surface is at 600 K, what is its total, hemispherical emissivity?

BONUS: A pipe with inner diameter of 1 cm has internal flow with Reynolds number of 1,000. The flow can be considered to be hydrodynamically developed after what distance from the entrance to the pipe?

Assuming that the lump capacitance assumption is valid for the thermocouple in Problem 1, what is the time constant for it? (“A spherical thermocouple (radius of 3 mm, thermal conductivity of 20 W/mK, specific heat of 400 J/KgK, density of 8500 kg/m3) with initial temperature 20°C is suddenly exposed to air at 90°C (h = 200 W/m²·K)”)

Calculate the total heat transfer through a composite wall consisting of two layers (k₁ = 20 W/m·K, thickness₁ = 0.02 m; k₂ = 40 W/m·K, thickness₂ = 0.04 m) with a temperature difference of 20°C across it per unit area.
