Biomedical Engineering 7-28

Biomedical Engineering 7-28

Students began the day with a discussion of how fluid mechanics played a role in the design of their heart models, and also discussed how the heart compared to other kinds of pumps. Next, they were given the chance to reflect on the design process of their BristleBots, which they had been working on all week. As a class, students put the finishing touches on the big heart model, and worked together to label the parts of the heart. They also prepared to present all of their projects to the parents at the end of the day.

Ask your student: Which parts of your BristleBot design were most effective? Which material would be the most versatile for building a BristleBot?

MYTHconceptions 7-28: Own Your Own Myth

MYTHconceptions 7-28: Own Your Own Myth

This week, students worked in groups to test their own myth. They used steps from the traditional scientific method in order to refute or support a claim. Today, students finalized their conclusions and shared their observations and results with the class. They made posters of their results and gave small presentations to the class.

Ask your student: What claim did your group test? Was it a myth?

Belleville MicroSTEM 7-28: Applied Circuitry

Belleville MicroSTEM 7-28: Applied Circuitry

Today, in MircoSTEM, the students examined real circuits in a calculator to see how a calculator functions and explore how numbers are displayed. Students focused on the display of the calculator, in particular how numbers are displayed using a 7-segment display.

Ask your student: What type of numerical display do most four function calculators have? (7-segment) What type of numerical display do most graphing calculators have? (Dot matrix)

Chemapalooza 7-28: So Sublime

Chemapalooza 7-28: So Sublime

Today students observed first-hand how regular ice and dry ice differ in their behaviors. Students studied both types of ice in one scenario, and used their observations to predict what would happen in a different scenario! Finally, collected evidence to make claims about the strange phase-changing properties of dry ice, created models, and presented them to the group.

Ask your student:  What is it called when a substance goes from a solid straight to a gas? (Sublimation) Ask your student to tell you some of the differences they observed between dry and regular ice.

Belleville Engineering Explorations 7-28: Rube Goldberg Competition

Belleville Engineering Explorations 7-28: Rube Goldberg Competition

Today students finished their Rube Goldberg machines, and took turns demonstrating them to the rest of the class! Using the Rube Rubric, each team was evaluated for the competition, and had the opportunity to observe all the different machines that were made.

Ask your student: How well did your Rube Goldberg machine perform?

Belleville STEMvironment 7/28: Air Pollution

Belleville STEMvironment 7/28: Air Pollution

Students today worked as scientists working for the environmental protection agency! As agents of the EPA, students collected their particle collectors, and observed the materials that were collected. By joining the data of the entire class, we were able to map the areas of greatest air pollution, and evaluate just where the most pollution occurred.

 Ask your student: What gas do we need to breathe to survive? (Oxygen) What is the best way to deal with air pollution? (Prevention) What is done to clean air we breathe indoors? (Air filtration)
