Science Review Pt. 1

Roll a marble down the ramp from a height of 10 cm, 20 cm, and 30 cm.

Pour 50 milliliters of water down four inclined surfaces.

Take the mass of five rocks separately and then determine the average mass in grams (g).

Conduct four trials of counting the bubbles produced by a water plant for 1 minute (min) each.

It does not represent the main parts of a cell.

It does not contain the correct number of nuclei.

It cannot represent a living cell, since a true cell is three-dimensional.

It cannot represent a living cell, since the cytoplasm should be in constant motion.

Binomial nomenclature is assigned to a recently identified plant species.

An endangered monkey species is put in a reserve for protection from extinction.

A newly discovered chemical element will be added to the periodic table of the elements.

A nonnative plant species will begin to reproduce rapidly after being introduced into a swamp ecosystem.

The discovery of new evidence resulted in changes to the atomic theory.

Advancements in atomic models proved the atomic theory was accurate.

The atomic theory was modified with the discovery of every new element.

Changes in atomic models showed that the atomic theory was based on opinion.
