1. Materials Required:

  • Two pumpkins
  • Multimeter
  • Alligator clip
  • Zinc strips, galvanized screws, or nails
  • Copper strips or thick copper wire
  • Safety goggles

With these materials at hand, students are poised to embark on an electrifying exploration of the latent power residing within pumpkins.

2. Experiment Steps:

  • Gather all necessary materials and arrange them neatly on a stable workbench or table surface.
  • Affix a copper strip and a zinc strip on opposite sides of each pumpkin. If copper and zinc strips are unavailable, substitute with readily accessible galvanized nails and copper wire, easily obtainable from hardware stores at minimal cost.
  • Establish electrical connectivity by linking the copper element of one pumpkin to the zinc element of the other pumpkin using the alligator clip.
  • Utilize the multimeter to measure voltage. Connect the black lead from the multimeter to the remaining zinc strip and the red lead to the remaining copper strip.
  • Adjust the multimeter setting to the voltage measurement mode (marked as “V” with a line above). Record the voltage reading, which should ideally register at least 1.5 volts or higher. If the reading falls short, double-check all connections for accuracy. Note that voltage readings may vary depending on the specific materials used and the size of the pumpkins employed.

The underlying scientific principle of this experiment lies in the acidic juices present within pumpkins, which facilitate the transportation of electrical energy. As zinc ions relinquish electrons, these particles traverse to the copper element, generating a flow of electricity.

  • Measuring cup
  • Tablespoon
  • Small cups
  • Warm water
  • Dry yeast
  • Hydrogen peroxide
  • Safety goggles

With these materials in hand, students are poised to embark on an exciting exploration of chemical reactions, all while creating memorable Halloween-themed entertainment.

Experiment Steps:

  • Gather all the necessary materials and proceed to an outdoor location to minimize mess.
  • Open the top of the pumpkin to create a cavity for the experiment. Pour one tablespoon of dish soap into the pumpkin.
  • Add approximately 10 drops of food coloring into the pumpkin. Adjust the quantity according to desired color intensity.
  • Pour half a cup of hydrogen peroxide into the pumpkin, ensuring it reaches the bottom.
  • In a separate container, mix one tablespoon of dry yeast with three tablespoons of warm water. Stir the mixture for about one minute to activate the yeast.
  • Carefully pour the yeast mixture into the pumpkin through the opening. Observe as the pumpkin begins to foam, creating an eruptive effect.

Explore variations in ingredient quantities to observe changes in foam density and eruption intensity, providing insight into the dynamics of the chemical reaction at play.

The underlying scientific process driving this experiment is as follows: the foaming action within the pumpkin is triggered by the yeast. Upon addition of warm water, the yeast becomes activated and primed for reaction. As the yeast interacts with the hydrogen peroxide, it catalyzes a reaction wherein oxygen atoms are stripped away, effectively converting the hydrogen peroxide into water.

Consequently, the hydrogen peroxide decomposes into water and oxygen gas. As the oxygen gas is released by the yeast, it interacts with the dish soap, resulting in the formation of foam. The rapidity of this chemical reaction propels the foam outward through the openings in the pumpkin, culminating in the characteristic eruption or “vomiting” effect observed.

Spooky Halloween Punch

While Halloween often conjures images of elementary school parades and parties, high school students also crave the thrill of spooky celebrations and engaging activities. This experiment offers the ideal opportunity to infuse your high school science class with a dose of eerie excitement.

  • Heavy gloves
  • Dry ice
  • Safety goggles

With these materials at hand, students are poised to delve into a thrilling exploration of scientific phenomena, all while embracing the festive spirit of Halloween.

Experiment Steps:

  • Fill the punch bowl halfway with the chosen liquid refreshment, leaving ample space for the “fog” to fill the rest of the bowl and cascade over its edges.
  • Don goggles and heavy gloves for safety. Carefully place several pieces of dry ice into the punch bowl. Immediate bubbling and fog effects will ensue, but allow a few minutes for the spectacle to fully develop.
  • Exercise caution and wait until the dry ice has completely dissipated before serving the punch to students. If serving immediately, utilize a strainer to prevent any dry ice from inadvertently entering their glasses.

The Science Behind the Spookiness:

Dry ice, composed of frozen carbon dioxide, boasts a chilling temperature of -109.3°F (-78.5°C). Unlike conventional ice, dry ice undergoes sublimation, transitioning directly from a solid to a gas as it warms.

This unique process fuels the eerie fog effect observed in the punch bowl, adding a captivating touch of scientific intrigue to Halloween festivities.

How to Show Your Teachers Appreciation

As a building principal, I know there are numerous meaningful ways to recognize and appreciate teachers’ dedication. Drawing from my experience as a former principal, I’ve found various approaches to expressing gratitude that genuinely resonate with educators.

One memorable way to show appreciation is by organizing special events. For instance, I once used the district’s barbecue grills to prepare a freshly grilled lunch for the staff. The weather cooperated, allowing teachers to enjoy an outdoor picnic during their lunch period, creating a delightful and relaxing break in their day.

Another year, I purchased a picture book for each teacher and wrote a personal message on the cover. This book became a cherished resource for reading aloud to students at the start of the school year.

Perhaps the most impactful appreciation event was a weeklong game where teachers earned points for performing positive acts for their colleagues. Teachers recorded themselves engaging in these acts, adding a fun and interactive element. At the end of the week, points could be exchanged for exciting prizes like wearing jeans for a day, class coverage, or car washes. The teacher with the most points won a special lunch provided by the principal. This activity recognized individual efforts and fostered a strong sense of community among the staff.

Traditional appreciation methods may not be feasible due to COVID-19 restrictions, and some staff members are still teaching remotetion methods. However, technology offers new avenues to show gratitude. For example, principals can use Google Forms to collect positive comments about teachers. These comments can be framed and presented to the teachers, adding a personal touch. Another idea is to gift teachers a T-shirt with a catchy slogan that captures the essence of the 2020-21 school year.

Whatever the method, the key is sincerity. Ensuring appreciation efforts come from the heart makes Teacher Appreciation Day an extraordinary occasion, celebrating teachers’ incredible impact on their students and the broader school community.
