Everything You Need to Know About Fonts for Display Boards

Project Resource

The most important objective for your board is to effectively communicate the facts about your project. You can only achieve that objective if it's easy to read. Over the years, expert newspaper editors, as well as advertisers (Ogilvy 1983, 90) have formulated many rules of thumb for readability that we have translated for use on science project display boards. Use a font size of at least 16 points for your main body text. Anything smaller is too hard to read. (See the… Read more

How to Solder Electronic Components: Electronics Primer

Project Resource

Overview What is soldering and when should you use it? Soldering is a process in which two or more metal items are joined together by melting and then flowing a filler metal into the joint—the filler metal having a relatively low melting point. Soldering is used to form a permanent connection between electronic components. The metal to be soldered is heated with a soldering iron and then solder is melted into the connection. Only the solder melts, not the parts that are being… Read more

Scratch User Guide: Adding Images & Sprites to a Scratch Program

Project Resource

Introduction One fun feature of Scratch is that you can easily add any images and text that you want to your program. Do you want to draw a new Scratch cartoon character directly on the computer?

How To Grow Bacteria on Agar Plates

Project Resource

Growing bacteria, or other microorganisms, on agar plates is a common step in microbiology experiments. There are two methods for inoculating (putting the bacteria on) agar plates: quadrant streaking and spread plating. Which one you choose depends on what you want to do after. Quadrant Streaking Bacteria or Fungi The quadrant streaking technique is used to isolate single colonies of one or more types of bacteria or fungi. To get started, you will need: A clean, sterile work… Read more

All About Agar

Project Resource

An Introduction to Agar With its distinctive smell, one can easily distinguish agar from the other materials commonly found in a laboratory. Chemically, agar is a polymer made up of subunits of the sugar galactose, and is a component of the cell walls of several species of red algae that are usually harvested in eastern Asia and California. Dissolved in boiling water and cooled, laboratory agar looks gelatinous. Although agar's chief use is as a culture medium for various microorganisms,… Read more
