control. The classroom observed had all the necessary areas of a preschool room. The room had a house keeping/dramatic play area as well as a block area‚ writing‚ science‚ computer‚ music‚ reading‚ circle‚ manipulative and art areas. All of the areas were appropriately spaced out and comfortable for the children. The house keeping/dramatic play area was the first visible area one would see when entering the class. This area includes a play stove and refrigerator with plastic food.

1. What is the relationship between rate of ion exchange and surface-to-volume ratio? - As the surface-to-volume (SA:V) decreases the rate of ion exchange will also decrease. 2. Why is it important for a cell to have a large surface-to-volume ratio? - If the SA:V is too small then then rate of ion exchange will decrease‚ if this rate of ion exchange is too low then the cell will no longer be viable. 3. Which is more efficient at exchanging materials‚ a small or a large cell? EXPLAIN

decimals in these area students apply their understandings of fractions and fraction models to represent various types of addition | |and subtraction of fractions with unlike denominators. The second standard in which I chose was 3 D shapes. This allows students to relate two-dimensional shapes. It helps them to understand | |and recognize the total number of same sized units of volume that they need to fill a space without gaps or overlaps. They use these shapes and find surface areas and volumes

test is used for fine grained soils like silts and silty clays. For the Variable head test the following formula is applicable: Where‚ k = Coefficient of permeability at To C (cm/sec). a = Cross Sectional area of stand pipe (cm2). L = Length of soil specimen (cm) A = Cross-sectional area of soil sample inside the mould (cm2) t = (t1 – t2) = Time interval for the head to fall from h1 to h2. h1 = Initial head of water at time t1 in the pipe‚ measured above the outlet. h2 = Final head of water

Parachute Experiment Aim: To investigate the effect of surface area on a performance (more the amount of a parachute better the performance) of a parachute. Hypothesis- More the amount of holes in a parachute‚ faster the rate of the fall. Variables: Dependent variable- The time it takes for the parachute to reach the ground. Control variables:Mass > Adding or subtracting mass from the load. > Clay can be molded around the load to increase mass. > Parts of the load can be cut off to decrease the
