21/22 In-Classroom Activities

Learning Undefeated is providing new activities for the Drop Anywhere Labs.  These activities will bring hands-on investigations to concepts students are learning in the classroom. Learning Undefeated will provide the materials needed to complete the activiy and will be available to assist in the classroom as a teaching assistant.

Activity duration: All activities are 45-60 minutes in duration.

Class size: The Drop Anywhere Lab can provide equipment and supplies for up to 40 students at a time for class.

Pandemic-related schedule changes: All schools with pandemic-related cancellations will be able to reschedule for a later date. Learning Undefeated will attempt to reschedule the visit during the current school year or offer priority access to the next school year’s schedule.

What's in a Change?

In this experiment, students are introduced to chemical and physical changes and challenged to use data and observations to determine types of changes.  Students will observe physical and chemical properties of reactants and products to determine if a new product with different properties is created.  Students will look at two reactions: dry ice with water and calcium carbonate with acetic acid.

Mixing Things Up

In this experiment, students are challenged to determine if powdered drink mixes like Gatorade combine with water to create a mixture or chemically react to create a new substance called Gatorade.  Students will attempt to separate the combination by filtration and then by distillation.  Students will calculate the densities of reactants and products to determine if a new product with different properties has been created.

Wait, Weight?

In this experiment, students are if the law of conservation of mass holds true for both physical and chemical changes.  Students observe two color-changing reactions, one physical and one chemical, and use scales to determine if the mass changes throughout the reaction.

MS-PS-1-5: Develop and use a model to describe how the total number of atoms does not change in a chemical reaction and thus mass is conserved.

How Water Moves

In this lesson, students will be asked to predict the movement of water over defined landforms.  Students will have the opportunity to use an Augmented Reality (AR) sandbox to see how water flows over landforms and how the motion changes when the landscape changes. Students will then have the opportunity to view a second model, stream tables, to see erosion and sedimentation in real-time.

Where Did the Sugar Go?

This activity focuses on how sugar moves throughout the body and the effect diabetes can have on these processes.  This activity includes 3 student stations: meal prepping, monitoring, and motion.  At the meal prepping station, students are challenged to plan a meal that fits the carbohydrate constraints of a diabetic patient.  At the monitoring station, students use a glucometer to test simulated patient blood samples taken before and after eating a meal.  At the motion station, students use glucose test strips to test simulated patient plasma samples taken before and after exercising.

MS-LS1-3: Use argument supported by evidence for how the body is a system of interacting subsystems composed of groups of cells.
MS-LS1-7: Develop a model to describe how food is rearranged through chemical reactions forming new molecules that support growth and/or release energy as matter moves through an organism.

It's All in Your Head

In this activity, students will learn about Newton’s laws as they learn about concussions.  Students will use a physical model to investigate the effect of low and high impact forces on the human head.  Students will then have the opportunity to use force plates to test different materials for their ability to reduce impact forces and ultimately inform students’ decisions on which materials to include in a new helmet design.
