This is our first STEM project of the year. Our goal was to see who could build the tallest tower with only using index cards and plastic cups. We learned that it is okay to not succeed on the first try. We learned from our mistakes and found better ways to create our towers.
CSI Identification- Examining Cells; We had to put on our lab coats for this one. Our goal was to observe and analyze 30 different cells. We had to identify them as an animal cell, plant cell, or not a cell at all. We had to figure out who broke into Mr. Worrywart’s house based on the clues left at the scene. Our three suspects each carried a bag made of different materials. We had to match the cells to the correct bag.
We’ve learned about the different symbiotic relationships within ecosystems. We had to research and create an ecosystem that displayed the three types of symbiotic relationships: mutualism, commensalism, and parasitism. We had to be able to explain how the organisms in our ecosystems created a food chains and food webs.
This is our first visit to the STEM Lab. Our goal was to explore the different types of microscopes and make a guess about what we were looking at. We had to use what we learned about cells to come up with a hypothesis.
When we discussed asexual reproduction, one way that plants reproduce is through their cuttings. We have philodendron cuttings that we are continuing to observe. Each day, we place our cuttings in the sun and continue to water each plant. Our goal is to continue to nurture these cuttings to create a mature plants.
Our chia plants are growing! We worked together with other grade levels when we were discussing photosynthesis and reproduction. We know that plants need water, carbon dioxide, and sunlight. In the STEM lab there is one window. We experimented with our chia plants. Our plants were growing towards the window, sunlight. The next day, we turned the plants around to see if the plants would change directions. They did! The students were very excited to see their hypotheses was correct.
Holiday Fun! Our room parents introduced an activity using candy canes. The students were asked to work together to move the candy canes from the middle of the group to the their plate at the end of the group. The students were not able to touch the candy canes with anything except for their candy candy that they had in their mouth. Through trial and error, the students found various ways to reach their goal quickly.
Building Bridges We were given the task of creating a bridge using at least 200 popsicles but no more than 500. We were only allowed to use hot glue, with our teacher’s help of course. Our bridge had to span at least 14 inches. When completed, our bridge needed to withstand 20 pounds (of sugar) for at least 1 minute. Our teachers started the process by showing us six different types of bridges and allowing us to research and decide what bridge would be best for our project. Then we were allowed to pick from several different group jobs. We were all able to choose a role that was important to the design of our bridge. Throughout the process we learned how different students excelled with different jobs, but in the end, we all came together to build two successful bridges. We challenged one another to go farther, to brainstorm on different ideas, and to complete our task.
