Who Wins the Barbeque Showdown Gas vs. Charcoal Grills

Friday, August 21st, 2009

The debate over which grill is better–gas or charcoal–may not induce as many passionate and polarized opinions as a political campaign, but for outdoor cooking enthusiasts it comes pretty close. Die-hard grilling aficionados swear by the flavor and process of cooking with charcoal grills. But with the majority of new grill purchases being gas models, there are obviously fans in that camp, too.

So which grill wins the debate? Let’s look at the arguments for both. The case for gas or charcoal seems to be divided along three main points:

  • Convenience
  • Cost
  • Taste

The Convenience Argument

The clear winner in this category is the gas grill. Most models feature push-button ignitions, a consistent, steady heat source that’s ready to go within minutes, excellent temperature control, and easy cleanup.

But convenience isn’t necessarily a deciding factor for all grill shoppers. Charcoal enthusiasts say it’s the ritual–piling up the charcoal, lighting it, tending the fire, and manually adjusting cooking temperatures by moving food from hotter spots to cooler ones–that makes outdoor cooking worth the effort. They feel that trading the process of the backyard barbeque for the push-button convenience of a gas grill is missing the point.

The Cost Argument

If cost is the most important deciding factor for you, you’ll likely want to look at charcoal grills. They cost considerably less than gas, with basic models ranging from about $30 to $100. If you add features like additional burners and side tables, you can count on something like a $300 to $400 range.

Most gas grills–excluding portable and table-top models–are on the expensive side, ranging anywhere from $300 to $1500, and more for higher end models such as built-ins and smoker/grill combinations.

The Taste Argument

Though some barbeque fans swear they can’t tell the difference between food cooked on gas grills and food cooked on charcoal, the charcoal purists insist otherwise. According to them, the flavor that is infused from the smoke of charcoal briquettes or wood coals is what distinguishes an outdoor feast from a standard kitchen meal.

In an effort to address the taste issue, some gas grill manufacturers have built models that add ceramic flavor bars. These bars catch grease drippings and vaporize them into smoke that infuses more flavor into what’s being cooked.

So who’s the winner in this category? The jury is still out on this argument, and it probably always will be. Taste is such an individual decision; you may just have to try both grills and see for yourself.

For Those Who Still Can’t Decide . . .

As you can see, there are pros and cons to owning a gas grill, just as there are advantages and disadvantages to owning a charcoal model.

Still aren’t sure which one is right for you? Do what many families have done in recent years–buy both! If you truly enjoy outdoor cooking, it makes sense to own two models that you use for different purposes. For example, you can use the gas grill for cooking quick barbeque meals during the week, and break out the charcoal grill for when you want to take your time on the weekend.

There are a couple of options available to you if you want to own both a gas and a charcoal grill. There’s the obvious one: buy both grills. But if your budget is tight, or you’re limited on patio space, check out a combination gas/charcoal model. These grills convert from gas to charcoal and back again with just a little preparation and effort.

So what will it be–gas, charcoal, or both? In the end, the decision comes down to your lifestyle and what features work best for you and your family.

Measuring Your Shadow

Saturday, August 8th, 2009

Have you ever shined a flashlight against a surface in the dark. If you point the flashlight straight toward a wall, for instance, you’d see a small circle of light. But if you slant the flashlight upward, the circle gets larger.

In the same way, sunlight is more concentrated in one area when it hits the earth directly, and when the sunlight hits the earth at a slant, the sunlight spreads out, making it less intense.

In the following activity, ultraviolet will be referred to as sunlight.

Purpose of this activity

To learn about the angle of the sun to the earth and how it affects you.

What you will do

Observe and measure your own shadow. Choose a weekend to perform this activity when you’ll be able to return to the same location throughout the day. If you’re a child wishing to complete this activity and you need help, ask a parent or older brother or sister to assist you.

What you’ll need

Measuring tape, notebook, pencil or pen, and chalk.

Procedure:

  1. Begin this experiment around 8 or 9 a.m. on a sunny day.

  2. Stand in the same place, your back to the sun.

  3. Draw a circle around your shoes with the chalk.

  4. Observe your shadow. Is it long or short?

  5. Draw another circle around the head of the shadow.

  6. Measure the distance from one circle to the next.

  7. Write the time of day and the distance in your notebook.

  8. Continue to do this every one or two hours until around 4 or 5 in the afternoon.

  9. Record in your notebook what you observed about your shadow. For instance, did it get longer or shorter throughout the day or did it increase and then decrease in size? When was your shadow the longest? Shortest? Did it change direction?

What’s happening

You observed the sun’s movement as you were watching your shadow. When your shadow is long earlier and later in the day, the sunlight is less intense and at a lower angle. When sunlight is more intense between 10 in the morning and 4 in the afternoon, but particularly an hour before and after noon, try to stay in the shade and wear sunglasses, sunscreen, a hat with a wide brim and clothing that covers you.
