Evaporation and Transpiration: What’s Your Function? Middle School Activity

Published on October 20, 2021

What’s the difference between two common agricultural methods? What are the roles engineers play in designing better methods? In this activity, students calculate evapotranspiration rates--the amount of water lost from evaporation and transpiration in a growing media (such as a pot or jar) and plant surfaces-- for living plants using soil and hydroponics. By recording changes in plant weight, students calculate evapotranspiration rates and determine which of the two growing methods is best for their design.

Paper Towers and Pool Balls Design Challenge High School Activity

Published on October 19, 2021

How can teamwork and project-based learning help us understanding engineering practices? In this activity, students are presented with two problems that must be solved physically. In the first problem, they must construct the tallest tower possible out of limited materials. In the second problem, they must find a way for a rolling pool ball to take a set maximum time to cover a specified distance. Students create and follow a design and are assessed by the performance of their creations. The students use the Engineering Design Process (EDP) to complete the two hands-on activities. This is an experiential learning experience for the student where they learn to collaborate ideas between teams, while also competing against each other. The sharing of knowledge is the path.

Using the iodine solution process as a control, student teams plan how to image the cells, evaluate the results and make recommendations to improve the imaging process.

preview of 'Mathematical Modeling- Linear Approximations' Lesson

Mathematical Modeling- Linear Approximations High School Lesson

Published on August 6, 2021

Students investigate the idea of linear approximation. Students apply mathematical modeling, specifically linear approximation, to an already collected data set to make a prediction. In this lesson, students first engage in a warm-up that is not a perfectly linear data set, being exposed to this for the first time. Students take on the role as a packaging engineer to learn the process to apply linear approximation modeling: collecting data, creating a graph, drawing a line-of-fit, creating a model in the form of an equation, defining the model’s variables, and evaluating with the model. Students ultimately use their linear model to predict the net weight of cereal in grams contained by 260 square inches of cardboard packaging.

preview of 'Judgement with Jellybeans' Activity

Judgement with Jellybeans High School Activity

Published on August 6, 2021

Students collect data and apply mathematical modeling, specifically linear approximation, to predict what will happen in a specific situation. In this activity, students collect data to determine the number of Jelly Belly jelly beans it takes to fill up the respective tube. Students plot their data, graph a linear approximation model, and write an equation representing their model. Students use their linear model to predict the number of Jelly Belly jelly beans that are in a similar cylindrical tube with a given height. Students discuss the accuracy of their results and limitations in their model and data collection process. They then apply their predictions to make suggestions to Jelly Belly for potential packaging of jelly beans based on quantity instead of net weight.

preview of 'Using Jupyter Notebooks to Explore Waves' Activity

Using Jupyter Notebooks to Explore Waves Middle School Activity

Published on June 30, 2021

As an introduction to analyzing sinusoidal waves, students learn how to use a Jupyter Notebook. They learn how to identify the frequency, wavelength, amplitude, period, and phase of a simple sinusoidal waveform. As they learn how to label the parts and properties of the waves, they connect these characteristics of waves to various real-world wave examples such as ocean waves, visible light, and sound. Students will examine a mathematical model of a sinusoidal waveform and connect each variable to its corresponding wave property. They will manipulate each variable of the model using Python code in a Jupyter Notebook and examine the effect of changing each variable on the resulting waveform.

Students consider cases where schools were forced to close due to outbreaks, then collect data and evaluate real-world procedures designed to prevent outbreaks. Their evaluation will lead students to determine how common processes are falling short and use that information to provide recommendations to their own school.

preview of 'Modeling Nuclear Damage from Cell Movement' Activity

Modeling Nuclear Damage from Cell Movement High School Activity

Published on May 26, 2021

This engineering design activity simulates building a model to visualize and measure DNA damage within the nucleus as the cell migrates through the extracellular matrix (ECM). As students learn more about the structural composition of the ECM and the nucleus, they come to understand that both the ECM and the nucleus vary in stiffness and elasticity. Mechanobiologists have recently discovered that this feature plays an influential role in regulating numerous cell functions, as cells have the ability to “sense” their mechanical environment. The stiffness of the ECM is particularly important in the spread of cancer throughout the body. In this activity, students model the movement of a cell through a stiff matrix and measure the impact on the nucleus as DNA damage caused by the stress of this movement in relation to the amount of nuclear lamins, the major architectural proteins of the animal cell nucleus, present.
