Physics
What are Newton's Laws of Motion? Hint: there are 3 of them
1st Law An object in motion stays in Motion an object at rest stays at rest. Unless it is acted on by an outside force.
What is the similarities and differences between Protons Neutrons and Electrons?
Protons are positively charged. Neutrons are not charged. Both of these live in the Nucleus of the atom and are the same size.
Electrons are negatively charged they live in energy levels outside the atom. they are about 1/1000th the size of a proton.
What role does DNA play in our bodies.
DNA is the instruction manual for our bodies telling it what it needs to make.
What is a hypothesis?
a guess that is written in a it then statement. as to explain what is going to happen.
What's the difference between weathering and erosion?
Weathering is the breaking down of rocks into smaller pieces.
Erosion is the movement of rocks to a new location.
If you are ever in a car accident explain what happens to your body using Newton's law.
Newton's first law shows that an object in motion will stay in motion so when the car accident happens you will stay in motion unless something stops you.
What does Reactivity mean?
How easily something reacts.
What is the difference between a dominant allele and a recessive allele?
Dominant allele will always show up when it is present in the offspring. DD, Dd
Recessive will only show up if the dominate version is not present in the offspring. dd
Make 3 observations an one inference about Mr. Huddleson.
answers will vary.
What are the 3 types of rocks how are they made?
Igneous - lava cools down
Metamorphic - heat and pressure applied for a long time.
Sedimentary - little pieces of rocks getting stuck together.
Explain the difference between Mass and Weight.
Mass is how many particles of atoms are packed in a certain space. Weight is the effect gravity is acting downwards on those particles.
What is an Ionic Bond?
Ionic Bonds are bonds where electrons are stolen from element and held onto by another. Example would be table salt NaCl
A green pea plant was breed with a yellow pea plant. Green is the dominant color and the green pea plant is heterozygous. What are the resulting phenotype and genotype from this cross?
Phenotype 50/50 green and yellow
Genotype 50% Gg 50% gg
How do we know a chemical reaction took place.
Change of color
Temperature change
participate forms
gas or bubbles form
Rock plantes earth mercury venus mars
Gas planets Uranus jupiter neptune saturn
you are measuring your speed while you are running to try to improve your time for an upcoming race. You run 2 km in 10min, then 3 Km in 20 min then 2 km in 12 min and finally 1 km in 8 min. What was your average speed?
2+3+2+1=8Km= distance
10+20+12+8=50 min = time
8/50=6.25 min per km
What does a family tell us about an element on the periodic table? What does a period tell us?
Families tell us how they are going to react. all elements in the same family react similarly in situations.
Periods tell us how many valance electron levels they have.
What is made at the end of Meiosis?
4 cells that are all haploid ready for reproduction.
What are the two types of variable what is different about them?
Independent - the thing the scientist changes during the experiment
dependent- the thing the scientist measured during the experiment.
what are the difference between a convergent boundary transform boundary and divergent boundary?
Convergent move towards each other makes mountains volcanoes and earthquakes.
Transform slid past each other makes earthquakes.
Divergent move away from each other and make ridge valleys and earthquakes.
A car accelerates on the interstate from 40mph to 75mph in 5 seconds what is its acceleration ?
vi= 40
t= 5 35/5=7 Mi/Hr2
What is the difference between a Nonpolar covalent bond and a polar covalent bond?
Nonpolar is when they pull with the same strength so they are evenly shared.
What are the steps of Meiosis? explain what happens at each step.

Protein synthesis. DNA is read and copped by Mrna then it is brought to a ribosome where it is read and codons bring amino acids to make new proteins called trna.
Describe a big stars life span from birth to death.
Born in a nebula grows old by burning up all its hydrogen while it is a main sequence star. Transitions into a red giant by running out of hydrogen and burning helium. When no more fuel blows up in a supernova becoming a black hole or a neutron star.
