In honor of National Engineers Week, fifth graders used the engineering design process to design the most affordable windmill that could lift the most weight. As a part of our data unit, they were examining the relationship between cost and efficiency, quickly learning that there was no relationship between the two variables. What's this mean? That both cheap and expensive designs could lift both low and high numbers of washers. Great work engineers (and mathematicians)! |

Fifth graders are seeing how they can collect new types of data based on different amounts of potential and kinetic energy! Between changing the ramp height and the mass of a car, students collected distance and time data to see the relationship between a car's potential and kinetic energy! Way to go 5th grade!

]]>We kicked off our study of energy by looking at two simulations. They've given students an understanding of both potential and kinetic energy and their various forms. They've also given students an understanding of how energy can transform from one form to another!

As fifth graders wrapped up their plant investigations, they had a chance to create a group graph of the data they collected. Each graph was a mathematical model to answer the question they originally set out to answer, and students had to identify any of the trends their model showed. Students began defending the reasons behind the trends...awesome work fifth graders! |

We continue to gather plant data on our grass seeds...so check out the post below!

Students saw a repeating pattern as the amount of the moon illuminated decreased and then increased. They could determine when the next approximate full moon would be, as well as the next new moon.

"So that's how we could know when the next full moon would be even though that day hadn't happened yet!!!"

YES!

]]>"So that's how we could know when the next full moon would be even though that day hadn't happened yet!!!"

YES!

As fifth graders dig deeper into understanding the importance of data collection and analysis in science, they are designing their own investigations around plants to collect real-time data themselves. We'll be using a wide-variety of tools to help us do this, practicing metric conversions, finding averages, and looking for trends in the data. Way to go 5th grade! |

Using sunrise and sunset data, fifth graders are determining the amount of elapsed time between when a city on Earth first faces the sun (sunrise) and when that same location no longer sees the sun because it's turned away from it (sunset).

Using the elapsed time data, students are graphing them to see what this looks like at four different cities over the Earth, all of which have a different latitude (Chicago, USA; Nuuk, Greenland; Quito, Ecuador; and Buenos Aires, Argentina. Check back soon as we look to uncover trends in the data!

After organizing the data, students had to work in teams to display it and analyze it. Then after finding the mean, median and mode of the data (if they were able to!), students had to determine which statistic best represented the data.

We had some INTENSE but meaningful discussions in class, and surprisingly, the mean wasn't always the best way to show what was typical of the class. We'll be uncovering how scientists can use these statistics in their data collection as they work to answer questions. Keep up the great work 5th grade!

Working like scientists, fifth graders are taking data they collected and are working to organize it, display it graphically how they can best represent it, and then analyze it! It's incredible to see how their thinking evolves as they uncover more about data analysis!
