This week we took a break from rocks and we learned about heating and everything like that. then we started a lab about lab where we brought rocks in and investigated

This week

This week we had a test on the unit of rock formation. Finley was out for that. After that we headed on studying rocks. We did an experement with looking at rocks that were the same types. We had to disquinguish the rocks and describe it. rocks cryatalize larger when they take longer to cool rather than when it cools quickly the cryatlas are really small that was basically our week

The Week

This week we leared about crystals and rocks. We did an experement wit cryatalization to see if our class hypothisis of crystals form biger when a rock cools slower than faster. In our experement we had moth balls and we melted them... We put them in different cups in diffrent cooling places. One in a cool area where that would resmeble where the rock would cool faster. Another in a room temp. area to see a mix of cool and warm and lastly a hot area to show the rock cooling faster. the next day we saw that the cooler area had tiny crystals the area of room temp. had a decient sixe crystals lastly the warmer area had the biggest cryatals. So we proved our hypothisis correct.. Lastly in the week we began a lab on rocks and trying t distinguish one type from the other. Some trays had the same types. Some rocks wrer very light some crystaly, some layerly. We've yet to finish it.

Week after X-mas

This week we started to talk about heat and 3 types of heating sourses. Conduction Convexion and Radiation. Monday we started to review review heating because we were off for holiday break. Tuesday we learned about convexion and that oven mitts are only ventelators to protect your extremities from the potentual dangers from the heat. We also learned about how when you put a spoon up to a burner that the paritcles heat up and warm up the spoon and you feel the heat.

Wendsday we learned about lava lamps and that when they get lifted by the particles It falls down. On thursday mr.finley was out and we reviewed this. Friday we took a quis and chilled out

This week

This week we mainly studyied tetonic plates and how the planet evolved over billions of years. The reason why we have a core full of magma was because a world like mars crashed into the Earth and mixed the land ind inner fratures together. Plates came together gorming mountains, or volcanos. As the volcanos erupted new land developed. We learned about the 3 different types of bounderies, Divergent, Convergent, and Transform Bounderies. Divergent bounderies is when plates move apart, Convergent ones are when the plates push together,this causes mountains and higher elevations/land to form, lastly their are Transform Bounderies this is when plates scrape past eachother

This picture is showing all the bounderies
These are the earths major plates

This week we stared to look at gelogical phenomineons. We discovered that once in New Jersey two plates spepperated and now it is a valley. We have discovered the different types of rocks. Metomorphic, Ignious, and lastly Sedmemntary. Ignious is formed from lova/magma that has been cooled and hardens, Sedementary forms sedement mud or clay that has been pressed together by pressure Metomorphic is formed by rock that undergoes through both pressure and heat. We also did a test about if citric acid made a difference in erosion compared to water. We emidiatly saw acid bubbling in the container and the chalk got smaller sat to the water the only real difference was the color. That was my week.

This week we learned about maps and contour lines indexes and more. We put to gether a map of new jersey and we saw that we saw that their was a valley or something inbetween mountains. We think this accures by earthquakes and that the plates shifted and thats why this valley is running throught NJ
