What science ideas did you learn?
This week in science class we learned a little more about a project we work on last week. For this project we had to figure out why so many kids were out from school. This week we found out the restaurants they ate at and which ones they got sick at. Then we wrote our observations and made a hypothesis. We also learned what a petri dish was and how to use it. Another thing we did this week was learn about macroscopic, microscopic, and sub-microscopic and what they are.
How did you learn these ideas?
We learned these ideas in many different way. For the project, were we had to find out where the students got sick, we looked at the results and made a hypothesis. That gave us an idea were the student may have gotten sick. Also, to learn more about petri dishes, we went to the bathroom and got a swab. After that we rubbed the swab against something we thought had a lot of bacteria or, then something that didn't have so much bacteria. Then we divided the petri dish into two parts and rubbed the swab with the bacteria on one side of the petri dish and the swab with no bacteria on the other side. We learned then when rubbing the swab you must be very careful.
Why is it important to know this idea?
It is important to know these ideas because when we had to look at the results from the restaurants we practiced making an observation and hypothesis. Even knowing how to use a petri dish is important. It is important because if you want to test something else, you would need to know how to use one.
