It is that sad time of the year again where we wish we had 20 sessions instead of 17. The STEM school year is at its end and we have enjoyed every part of it. Our projects were successful in launching their projectiles. I believe the fifth graders had fun and their parents enjoyed seeing them at work. The highest average of the day for the distance of our projectiles was around 252 cm. We have had an educational year and I am glad to have been the intern for the 5th grade class.
EggBert has returned and is now better than ever. He now wants to complete his goal of having a successful bungee jump but he needs the fifth graders to keep him alive. The fifth graders are learning about elasticity and a little about gravity. They are testing the number of rubber bands’ influence on how low the egg can drop without breaking. Lets wish Eggbert a terrific jump and hope that he survives.
Throughout the last two sessions the fifth grade class has been working on an educational website and answering questions from different worksheets while they did the activities. With this knowledge gained they can use it to help them with their end of the year project. This work is challenging and time consuming but the fifth graders managed to get through it.
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.
Today, the 5th graders made slime and balls. Both projects had a mixture of glue, borax, and water. The bouncy balls had corn starch also. Everyone enjoyed the project, even though it got a little messy.
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.
