Objectivity means science should be free from personal bias, ensuring accuracy and allowing experiments to be repeated reliably.
Create a question, formulate a hypothesis, identify variables, run the experiment or tests, and present the results.
Adhesion allows water to stick to other charged surfaces, influencing how it interacts with different materials.
Pressure people feel when they risk confirming a negative stereotype about their social group.
Diversity improves the real-world relevance of research by bringing multiple perspectives, benefiting different communities globally.
Science can cause harm if stereotypes influence frameworks or if research only considers one group, ignoring others.
The factor deliberately changed or manipulated to observe its effect.
The outcome measured or observed that changes in response to the independent variable.
The standard or baseline that experimental results are compared against.
The group that receives the experimental treatment or manipulation.
Large biological molecules made of smaller units called monomers linked into polymers.
Monomer: monosaccharide; Polymer: polysaccharide.
Provide energy and form structures in organisms.
Monomers: fatty acids and glycerol; Polymers: triglycerides, steroids, phospholipids.
Store energy and form cell membranes.
Monomer: amino acids/peptides; Polymer: polypeptides.
Help cells keep their shape and speed up chemical reactions.
Monomer: nucleotide; Polymer: nucleic acid.
Store and transmit genetic information.
Hydrophilic: water loving; Hydrophobic: water fearing parts of the soap molecule.
A cluster of soap molecules that forms when mixed with water, trapping oils inside.
Soap molecules surround oils with hydrophobic tails and hydrophilic heads, allowing oils to dissolve in water.
Water is a polar molecule with two hydrogen atoms bonded to one oxygen atom, creating partial charges.
High specific heat, cohesion, adhesion, universal solvent, and liquid water is denser than ice.
Water absorbs a lot of heat energy before its temperature rises significantly.
Water molecules stick to each other due to hydrogen bonding.
Water molecules stick to other charged or polar surfaces.
In ice, molecules are more spread out and slower, making solid water less dense than liquid.
