What Measurement device gives the most accurate Measurement
A)Beaker B) Flask C) Test Tube D) GraduatedCylinder
Graduated Cylinder
What is the smallest part of an element that still has properties of that element
An Atom
List the 4 Macromolecules
1. Carbohydrates
2. Lipids
3. Proteins
4. Nucleic Acids
Which macromolecule will the body digest first
Carbohydrates
Contrast Accurate vs Precise
Accuracy is how close you are to the correct answer, and precision is how specific the answer is. it is also how frequently you get that answer
What properties of water allow for Life to exist below a frozen surface
1) Adhesion 2) Cohesion 3)Terrific Solvent 4) High specific heat
High Specific Heat. Takes a lot of energy to warm or cool water
Which Macromolecule makes up the majority of the cell membrane
Lipids ( more specifically phospholipids)
Compare and Contrast Inference vs observation
Inference is a guess using the information from an observation
A) Observation B) Inference
What is a meniscus and what should
you do with it
The curve that is created with a liquid inside a graduated cylinder, you should always measure at the bottom of the meniscus
Which macromolecule would be responsible to movement and muscle contraction
Protein
List and independent and dependent variable and create a hypothesis using those variables
answers will vary
Write a hypothesis for IV=Caffeine and DV= Breathing rate of goldfish
If you increase the amount of caffeine in goldfish then their breathing rate will increase
Why does oil and water not mix
Oil is hydrophobic and a nonpolar substance
Water is a polar substance (Polar and Nonpolar does not mix)
What do must animals store their Energy reserves in.... and why
Fat (Lipids) because you can store twice as much energy in lipids then in Carbs
Mr. Campbell Has a dog (Technically 2 now)
What type of dog is she (bonus points for name)
(Luna the Goldendoodle is a new addition)
Create an experiment. List the IV, DV, Constants and Experimental group. How would you set up a control group?
List and Describe 3 qualities of water
1) Cohesion/Adhesion : The ability for water to stick to its self or other objects
2)High Solubility: Water is the universal solvent, dissolves all polar substances
3)High Specific Heat:heat required to raise the temperature of the unit mass of a given substance by a given amount
4) Surface tension: tension of the surface film of a liquid caused by the attraction of the particles in the surface layer
List monomers and polymers for each macromolecule
Carbs: Monosaccharides and Polysaccharides
Lipids: Fatty acids and Triglycerides
Proteins: Amino Acids and Polypeptides
Nucleic acids: Nucleotides and Nucleic Acids
Difference between Technological design and Scientific investigation
Technological Design is in the Creation and Application and Technology
Scientific Investigation is about the steps of testing and creating experiments and research activities
