God did it but how: what is a miracle? In the Bible?
- an extraordinary even, produced by God, at a specific time, as a sign of God's activity and purpose in human history - sometimes violates scientific law, sometimes does not - miracles don't have to violate scientific law, but they can, because when God does a miracle, he's doing something different in nature, not against nature
selective breeding
- everything we eat (pretty much) is selectively breed - look at the traits or genes wanted and decide to breed only certain organisms - selectively picking the parents so you get offspring that look like them - mate to get genes that you like and keep mating the ones that are "best"
genetically modified organisms
- taking genes from one species and moving it to another - not natural, you'd have to do this in a lab - example: adding drought resistant gene to a plant

M #1 Using the symbols for a battery and for a light bulb shown below, carefully draw in wires to make a circuit that will cause they light bulb to go on. The batteries shown here are both 1.5-volt batteries. What is the voltage of the combination of batteries shown below? What is the voltage of the combination of batteries shown below? Which, if either, of the combination of batteries shown in parts b) and c) would make a light bulb burn brighter?
negative goes to bottom, positive goes to side if they are both 1.5 the voltage of the combination would be 3 volts the voltage of the combination in parallel would be 1.5 volts because the batteries are working half as hard series would make a light bulb burn brighter because it has twice the voltage. now if we watned the light to burn longer we woudl say parallel. but if we want brighter, then series.

Explain why the leaves of the tree look green to the child, and also sketch in whatever photons you need to help you with your explanation. (Make sure that the sun is included in your picture and that it is included in your explanation.)
sun gives off photons that hit the tree, the leaves of the tree absorb all the colors except green. the leaves reflect the green photons which bounce of the leaves and hit the child's eye. thus, the child sees green leaves because the leaves reflect green photons
M #2 28. Psalm 104:5 says, "He (God) set the earth on its foundations; it can never be moved." Some people in the past have interpreted this verse as a scientific statement. They believe it meant meant that the earth is in the center of the universe, it does not move, and the sun and the moon move around it. Comment on this Biblical interpretation in light of our class discussions.
the Bible helps answer the question of who. who set the earth on its foundation? God did it. The Bible's purpose is not to be a scientific book, it answers who and why questions, not how. The verse is meant to point to God being creator and sustainer, not to try and explain whether the earth can or can't move/ The bible is unchanging, but science is changing. The Bible doesn't make scientific statements
What is the name of the scientific theory for how the universe came into being?
the big bang
M #2 26. Assume you can choose either of the two organisms shown here as a source of nutrition. Which of them would provide a more efficient transfer of energy (less loss of energy) from the sun to you? Explain why.
the corn would provide a more efficient transfer of energy. the corn would be a producer (because it is a plant), it makes its own energy. there is less of a loss of energy in transfer because the corn would not be a high level consumer (like the cow). the corn would lose less energy because it doesn't use or need as much as the cow
What always happens when the temperature of a gas increases? a. The gas expands. b. The gas pressure increases. c. The gas particles get bigger. d. The gas particles move faster.
the gas particles move faster
M #1 27. Consider three identical cars: The first one is not moving, and it is out of gasoline. The second one is not moving, but it is full of gasoline. The third one is moving at 30 miles per hour, but it has just run out of gasoline. Which car has the most energy? a. The one that is not moving and out of gasoline. b. The one that is not moving but full of gasoline. c. The one that is moving but has just run out of gasoline. d. They all have the same amount of energy. Explain your answer.
the one not moving but full of gasoline has the most energy. even though it isn't moving, it has a full tank of gas and lots of potential energy. if our definition of energy is how much change might occur, then the one full of gas would have the greatest potential for change
What would you notice in terms of sound if an object were made to vibrate more rapidly than it was before? a. The sound would reflect more. b. The pitch of the sound would get higher. c. The volume of the sound would get louder. d. The sound wave would travel faster
the pitch of the sound would get higher
Why does Michigan get so many potholes in its roads?
the roads consistently freeze over and then unfreeze with the temperature levels and water freezing. when it freezes, it expands and leaves cracks that the water can get into and thus expands the pavement resulting in potholes
What does evolutionism mean?
the world was created, but there is no God controlling or watching over it now
M #1 What are the three different ways thermal energy can be transported from one place to another, and which one of these ways depends on photons?
thermal energy can be transporrted from one place to another through conduction, convection, and through photons. energy through photons depends on photons.
Speaking from a particle perspective, what is thermal energy?
thermal energy is the total kinetic enrgy of all the particles in a suubstance
3. Why do the lenses of sunglasses look dark?
they look dark because they are absorbing photons and filtering a bunch of photons
Rocks found at the bottom of streams tend to be very smooth. Why?
tossed around a lot and the water and waves have eroded the rock and chunks of it have fallen off
If you are outside on a cold winter day, why would touching a metal pole feel colder to you than a tree trunk?
touching a metal pole would feel colder to us because metal is a really good conductor of thermal energy, the metal "takes the heat energy" from us when we touch it, thus feeling cold to use because it's good at transferring thermal energy
People hardly ever eradicate (remove) invasive species when they appear. Instead, they simply try to control them from completely taking over. Why is that? Why don't we completely exterminate invasive species?
very difficult to completely eradicate invasive species. also completely eradicating them could leave the ecosystem vulnerable and thus unhealthy because it could impact other organisms
How is sound energy produced?
vibrations
What would happen to our ability to do science if God did miracles all of the time?
we wouldn't be able to do science, becasue we would not have structure or order to base off of
What causes rocks in a stream to be smooth? a. Movement of fish b. Weathering c. Earthquakes d. Plate tectonics
weathering
M #2 15. What are some of the most common seeds humans eat worldwide? (List at least three.)
wheat, rice, corn, nuts
What causes earthquakes?
when 2 tectonic plates "crash" into each other
Photographs of the surface of Mars reveal the presence of sand dunes that move around over time. These dunes demonstrate the presence of what phenomenon on Mars? a. Wind b. Precipitation c. Plate tectonics d. Magnetic pole reversals
wind
M #2 29. What would the author of the book God Did It, But How? likely say in response to the little boy in the comic shown here?
yes. God had a hand in the rivers and the canyons. God created and controls the rivers and the canyons. God was directly involved in the the rivers digging the canyon
In terms of nutrition, what is the main difference between a vitamin and a phytochemical?
you need vitamins to survive, you don't necessarily need phytochemicals to survive, but you will live longer and better with them
M #1 Imagine that you had a microscope that was so powerful that you could see individual atoms. What difference, if any, would you notice if you used your microscope to look at the atoms in a hot cup of water and the atoms in a cold cup of water? How would they be different?
you would notice that in the hot cup of water, particles would be moving much faster than in the cold cup of water. Hot cup would have more thermal energy.
