Pizza can be a model of the earth.
The cheese and toppings simulate the lithosphere. The continental crust, and the oceanic crust. Some are more dense than others, and some are above the cheese and some are below the cheese, but they are all floating on the sauce. The sauce simulates the asthenosphere. It is between the "mantle" and the "lithosphere" The crust simulates the mantle. It is under the "asthenosphere" There was some magma see, and it wanted to be cool. So it shot up out of the volcano and became lava. Then it got real cool. So cool, infact, it hardened and turned into an igneous rock. But it still wanted to be cooler, so it jumped into a nearby stream and made friends with some bedrock. There it got broken up into smaller pieces. and they, along with their new friends decided to take a break and hang out in the side of the stream with some dirt and clay for a while. The longer they sat there, the further into the ground they got pushed, and they started sticking together. Soon, they were all part of the same rock, a conglomeration if you will. Now the pressure was on. It was getting warm too. As the rock traveled through the layers of the earth, it noticed it was starting to melt. soon, The rock was right back where it started. Not cool, and wanting to be.
You can use candy to simulate an igneous rock. We used a heath bar. It is smooth just like an igneous rock.
Sedimentary rocks, specifically sandstone, can be modeled by rice krispy treats. Sand is represented by rice krispies and the cement (glue) is represented by the marshmallow. Butterfingers analogue a foliated metamorphic rock, such as schist or phylite. They have very thin layers when you bite into them, just like a foliated rock. recipe:
4 pipe cleaners rectangle of sponge bits of charcoal briquet 3 oz. water 3 oz. liquid bluing 1 oz. epsom salt 1 oz. table salt 1 oz. rock salt 1 oz. ammonia was then poured into the solution Variables: sand, plaster, water
Cup 1: sand-100mL plaster-100mL water- 50mL Cup 2: sand-150mL plaster-50mL water-50mL Cup 3: sand-175mL plaster-25mL water-50mL 2 requirements for a fossil to be a fossil: 1- Must be the remains of a living thing. 2- Must be at least 5,000 years old. Cup 1 gave the best results. Cups 2 and 3 had too much sand and they were crumbly. Cup 1 was harder, but the shell wasn't too hard to get out. Relative ages are determined by the chronologic order of a sequence of events. Explain the most important methods of establishing relative ages:
1. superposition, origianal horizontality, and lateral continuity,
3. crosscutting relations- The rock that is cutting through the layers is newer than the rock that it is cutting through. 4. Inclusions- The rock that is included in another rock is older than the rock it is included in. 5. Unconformities-
What is Half-Life? Half lie is the amount of time it takes for an element or substance to decompose into half of what was there to begin with. How can you demonstrate this process to your kids? You could use skittles or m&m’s and you put them on a grid with 100 squares. You put them in a cup and shake them up, and count the ones that are face up. You then take the face-up candies and shake those up in a cup and count those face up candies. You continue that until you get to 0 candies that are face up. THIS IS WHAT I TOUGHT
What's the difference between weather and climate? weather is what we experience day to day. it is the precipitation, temperature at a given time, winds, etc.. Climate is the patterns that happen over a long period of time. This includes the dryness of the air, pressure, the amount of precipitation in a given area, average temperatures, etc... Name the tools to measure: air pressure- barometer Temperature- thermometer Humidity- hair hygrometer cloudiness- not a clue wind speed- wind direction- rooster on top of the barn precipitation- solid-ruler liquid-bucket How much does a cloud weigh? It depends on the size of the cloud, and the amount of moisture in it. What are the components needed to make a cloud? Water, atmospheric gasses, heat. THIS IS WHAT I NOW KNOW Name the tools to measure: air pressure- barometer Temperature- thermometer Humidity- hair hygrometer cloudiness- cloud chart wind speed- wind sock wind direction- rooster on top of the barn precipitation solid- board and meter stick liquid-rain guage What are the components needed to make a cloud?How much does a cloud weigh? It depends on the size of the cloud, and the amount of moisture in it. What are the components needed to make a cloud? moisture, pressure(or temperature change), and condensation nuclei. Could be dust, ash, salt, smoke. -The Hopi's emergence into the present Fourth World. The more prevalent is that Spider Grandmother caused a hollow reed (or bamboo) to grow into the sky, and it emerged in the Fourth World at the sipapu. The people then climbed up the reed into this world, emerging from the sipapu. The location of the sipapu is given as in the Grand Canyon. -It also contains a myth of the proto-Indo-European origin, in which the creation arises out of the dismemberment of a cosmic being (the Purusha) who is sacrificed by the gods. |
