 # Fall 2021 Conference Demos

Flower Lab

Asking questions, collecting data, analyzing data, and writing using evidence are skills students need to practice. In this basic lab, we allow students the opportunity to practice their investigative skills so they are able to begin the process of becoming science fair participants with original investigations.

Forces & Motion: Introduction

In this  introductory lab, students push sleds down various ramps to explore Newton's first and second laws. Students will see the relationships between motion and forces by changing the properties of the sled and ramp to affect the sled's velocity, time down the ramp, and force on a spring at the end of the ramp.

Convergent: Introduction

In this introductory digital lab activity, students will investigate the geoscience process of plate convergence in both oceanic and continental plates. Students conduct experiments in order to see how time, plate type, and size impact the type of features and earthquakes present at the convergent boundary.

Using Mathematics:

Ramp - Sled Mass and Momentum

beta version

Students use mathematics to investigate the relationship between the mass of a sled and its momentum when it slides down a ramp.

Using Mathematics:

Law of Gravitation - Planet Mass

beta version

Students use mathematics to investigate the relationship between a planet's mass and the gravitational force that planet imparts on objects in space.

Waves on a String: Introduction

The goal of the Waves on a String labs is to allow students to investigate how sound waves can change. Students conduct investigations to understand the relationship between string thickness, length, and tension to the generated sound's loudness, wave speed, and wave form.

Predation

​This activity explores predator and prey relationships by looking at a marine ecosystem and changes in populations over time. Students explore a key component to ecosystem understanding: the back-and-forth patterns that occur as a result of the predation cycle (as the predator numbers increase, the prey population decreases, and vice versa).

Divergent: Introduction

This virtual introductory lab gives students the opportunity to investigate the workings of continental drift at divergent plate boundaries. They will see how plate type, convection current, and distance from the spreading center impact seafloor structures, spreading rate over time, and past plate motions at the divergent plate boundary.

Using Mathematics:

Ramp - Friction and Acceleration

beta version

Students use mathematics to investigate the relationship between a ramp's friction and the acceleration of a sled and it slides down that ramp.

Making Predictions with Math:

Newton's Second Law of Motion

alpha version

Students investigate how the roughness of a road impacts a truck's ability to accelerate. In doing so, students build their own mathematical model, make predictions with them, and explore their model's limitations.
