Name of Resource

Publisher

Standard

HS-PS3-4

Plan and conduct an investigation individually and collaboratively to produce data to serve as the basis for evidence, and in the design: decide on types, how much, and accuracy of data needed to produce reliable measurements and consider limitations on the precision of the data (e.g., number of trials, cost, risk, time), and refine the design accordingly.

Plan and conduct an investigation to provide evidence that the transfer of thermal energy when two components of different temperature are combined within a closed system results in a more uniform energy distribution among the components in the system (second law of thermodynamics).

Description

On this field trip students explore the forms of natural energy - focusing on the harnessing of the energy to convert to electricity. After students could choose a way to harness an energy of their choice and build it. (pizza box oven, foil oven, etc)

* possible building prior knowledge activity: a tank with a solid divider in middle. On one side, add boiling water mixed with blue food coloring. On the other side, add ice cold water with red food coloring. Remove the divider. Over time, you should have purple water. By taking temperatures you can record the thermal difference.

Questions

*3 guiding questions for students to explore

What are the sources of energy on Earth that we can use to convert to electricity?

  • Fossil Fuels, Nuclear Energy, Geothermal Energy, Solar Energy, Wind Energy, Hydropower

How does a solar panel create energy?

  • Solar panels have 2 plates made with varying atoms, one negatively charged, the other positively charged. When photons from the sun hit the negatively charged atoms, electrons released to the positive side create an electric current.

What materials could be used to harness the sun’s power?

  • Batteries, panels, heliostats

Periodic Table

Vida Systems (Google Expeditions)

HS-PS1-1.

Use the periodic table as a model to predict the relative properties of elements based on the patterns of electrons in the outermost energy level of atoms.

Description

Virtually experience the periodic table and learn about the elements, noble gasses, hydrogen, halogens, alkali, alkaline earth metals, metals, metalloids, nonmetals, rare earth metals, and actinide metal.

Questions

*3 guiding questions for students to explore

What do the numbers represent on a periodic table?

  • The top number represents the number of protons the element possesses within its atom.  The bottom number is the atom’s atomic weight.

What are noble gasses?

  • Elements that possess no odor, color, taste, and are not flammable. (Helium, Neon, Argon, Krypton, Xenon, Radon)

What are some differences between alkali and alkaline earth metals?

  • Alkali metals are metals that are generally unstable (especially in the presence of water) and Alkaline earth metals are generally more stable.

Buster VS. Pane of Glass

Publisher

Discovery VR

Standard

HS-PS2-3.

Apply science and engineering ideas to design, evaluate, and refine a device that minimizes the force on a macroscopic object during a collision.

Description

Students will join the MythBusters Jon and Brian as they watch what happens to Buster as he jumps from a 3 story height heading for a pane of skyscraper glass.

Questions

*3 guiding questions for students to explore

What energies must be considered in the following experiment?

  • Gravity, Potential Energy, Kinetic Energy

How could you minimize the force of the dummy on the skyscraper glass so that it would not shatter?

  • Enlarge the ‘footprint’ as to disperse the energy more at the point of impact.

Complete an egg drop from a three story height and prevent it from breaking.

  • *designs will differ but should employ the concept that energy at impact must be dispersed away from the shell of the egg and absorbed by the materials used

Name of Resource

Earthquakes

Publisher

Vida Systems (Google Expeditions)

Standard

HS-ESS1-5.

Evaluate evidence of the past and current movements of continental and oceanic crust and the theory of plate tectonics to explain the ages of crustal rocks.

Description

In this experience students will experience the causes and types of earthquakes, how they are measured, and how scientists record them.

Questions

*3 guiding questions for students to explore

What must be present in order for an earthquake to occur?

  • Fault lines between tectonic plates, convection of earth materials below the plates to cause a shift

What is the difference between an epicenter and hypocenter?

  • Hypocenter is the below ground origin, Epicenter is the point directly above the Hypocenter on the earth’s surface.

How do earthquakes reveal older rocks on the Earth’s surface?

  • Convergent, Divergent, and Transform Fault earthquakes all expose rock previously unobservable in different ways.  Convergent push rock upwards (Himalayas), Divergent separate creating cracks in the crust (deep ocean chasms), and Transform Fault earthquakes slide exposing rocks at one end or the other.
