He wondered, Does the position of the pot determine the growth of the stem?<span>
He hypothesized that the plant’s stem grows perpendicular to the soil.
</span><span>To test his hypothesis, Brian placed the pot horizontally. He checked the plant after two weeks.
</span>
<span>Brian observed that a plant’s stem grows against gravity.
</span><span>On analysis, Brian found that the plant grew parallel to the soil. He modified the hypothesis, and then retested the experiment.
</span><span>Brian communicated the results to his science class.</span>
When ice forms, one water molecule's hydrogen atoms form weak hydrogen bonds with the tops of the oxygen atoms of two other water molecules. Lining up the water molecules in this pattern takes up more space than randomly arranging them.
<h3>What is polarity?</h3>
A physical property of compounds that connects other physical properties like melting and boiling points, solubility, and intermolecular interactions between molecules is referred to as polarity.
When ice forms, one water molecule's hydrogen atoms form weak hydrogen bonds with the tops of the oxygen atoms of two other water molecules.
Lining up the water molecules in this pattern takes up more space than randomly arranging them.
When water freezes, the water molecules slow down enough that their attractions arrange them into fixed positions. Water molecules freeze in a hexagonal pattern, with molecules further apart than when the water was liquid.
Thus, because of this frozen water take on the pattern it does.
