When ice melts it goes back to its original state of water. The question is, how does this new melted ice affect the amount of water that was present, and does it matter where it melts? The fifth graders were given two tubs of water and rocks. In the first tub they had to put the block of ice in the water, whereas in the second tub they had to put the block of ice on the rocks. The water respresnted the sea and the rocks represented the land. Which tub of water will have a higher level afterwards? Fifth grade found out that because the ice is already in the water it does not influence the amount of water already there.
Today, the fifth grade class learned a little bit about the Arctic and Antarctica. The fifth grade class had the job of finding out what items went into which category between the Arctic and Antarctica. Through this exercise they learned more about the different climates and different species that fit into these two places.
Today was the first day back for the interns but today is a whole new beginning for these 5th graders. They seemed excited, ready to learn, and prepared to have a good day. They were given the task of making a tall tower out of newspaper that could withstand Mrs. Casey’s blow of air from an arms length away. The 5th graders were very excited to build their tall towers, but they were a little disappointed when the wind knocked them down. I guess we can say that the 5th graders had a good first day.
Today in STEM the fifth grade class had to recreate their parachutes only this time they were on a budget. They could not get any more materials other than what they could purchase with their ten dollars. Not only was there a budget but instead of dropping a washer, they were dropping an egg, better known as Eggbert. They had the options of aluminum foil, dark or white plastic, masking tape, cotton balls, a bubble square, or a coffee filter. They could protect their egg with any of these items, however they planned, as long as they did not exceed their budget. All groups used different amounts of items and had different designs. Their choice of material and how they used it affected how Eggbert landed. Manny designs were made, and many parachutes were dropped, but only 1 Eggbert survived. I would like to say that the 5th grade class enjoyed this experiment overall.
Today the 5th grade class made and tested parachutes. They started with basic types of parachutes using only paper and tape. These rough drafts gave them ideas on how to build the real thing. After they tested the examples they began to make ideas about their final project. For their final parachute they had the choice of garbage bag pieces, aluminum foil pieces, or coffee filters. With these materials, tape, and string the 5th grade class had to guide a washer on to a target at the slowest time possible being dropped from a great height. This height was so great that Mrs. Casey was required to stand on a ladder with her arm reaching high. Our slowest time recorded was 1.70 seconds. The time and location of your landing all depended on how it was made, what materials were used, and how you required Mrs. Casey to drop it. It was really interesting to see the 5th graders’ competitiveness and enthusiasm for the project.
Last time at STEM the 5th graders went on a trip to the Peggy Notebaert Nature Museum. First we learned about honeybees, they got to learn all the differences between the three tyes of bees queen, worker, and drone. Then we got to explore the museum. We went to see where the bee hives are kept, even though the hives arent working right now. We also went through the butterfly greenhouse.
Today the 5th graders dicussed and learned about the differences and similarities of the North and South poles. As an expirament they had two containers. Both containers had water and pebbles inside. The water acted as the ocean and the pebbles acted as the land. To distinguish the two a L and W were written on each of the containers. Each group was given two pieces of ice, in L container the ice was laid on top of the land. In the container marked W, the ice was placed in the water. At the end of the project it was shown that the containers where the ice was on the land, that the water level rised more than the containers where the ice was put in the water.
Another short project they did today was being given cards, the cards had pictures of things like penguins, polarbears, seals, scientists, and volcanoes. They had to put the cards into three groups Antarctica, Arctic, and both. Many of the groups were suprised that some of the answers weren’t what they thought.
Watch where you put your hands because that hot plate is at 500 degrees Celsius!! On November 14th the 7th grade class experimented with balloons and a hot plate. The objective was to find out if the heated water in the beaker could make enough steam to blow up a balloon. For this experiment the materials needed were balloons, a hot plate, a beaker, and some water. Throughout the experiment they tested different measurements of water in the beaker to see if the balloons would still blow up. The amount of water in the beaker determined the size of the balloon. The beaker with the most water will have the biggest balloon because it can give off the most steam. In this experiment students learned about the hot plate and another way to blow up balloons.
Today the 5th graders finished testing thier paper airplanes from last week. Then they got to start building and testing thier egg bungees. To test using egg bungees they had to first drop the egg from one meter. When collecting data they had to change the amount of rubber bands used. After that they each dropped the egg from two meters. Each group had to measure the inches from the ground. One group even got as close as 5 inches!
