Teach Hypothesis Using Möbius Strips

By Janice VanCleave

Demonstrations are great for starting a class. The more magical the better. I suggest that you give no clues about what is going to happen. In fact,  make it as mystical as possible. Even prepare your materials in advance. Instructions: Students are asked to prepare for the demonstration. Regardless of age, all students are asked […]

Science Fair Projects: Parents Do’s & Don’t

By Janice VanCleave

Do’s and Don’ts 1. Do Be Positive. If you hated science when you were in school, now is not the time to discuss it. It takes time to design, develop, and prepare a display for a science fair project. So, it’s important to start on a positive note. 2. Don’t help too much. Remember that […]

How to Write An Experimental Science Project Question

By Janice VanCleave

The direction of the plant's leaves depends on the direction of the Sun. Sunlight is the cause—independent variable—and a change in the direction of the leaves is the response—dependent variable.

Building an Experimental Science Project Question New Science Terms causeeffectcontrolled variablesdependent variableexperimental questionindependent variablevariables An experimental question is a cause-effect question. Note: Things that can be changed or change on their own are called variables. In an experimental question, the variable that causes another variable to change  is called the independent variable. The  variable that […]

Einstein’s Messy Office

By Janice VanCleave

I enjoyed seeing the office of Albert Einstein as well as the offices of the other brilliant minds shown in the photos below. My first thought was that I must be brilliant because my office is often as messy as these. It just depends on how many projects I am working on. One technique that […]

What Is the Scientific Method?

By Janice VanCleave

The Scientific Method is a Problem Solving Process The scientific method is not a set of steps that must be followed in order with fidelity. The scientific method includes Research, Questions, Hypotheses, Experimenting, Collecting Data, Making Conclusions. But, the order is not set in stone nor is there a rule that all the steps are […]

Vortex Bottle

By Janice VanCleave

You can create a vortex by stirring a oit of water with a spoon. But a vortex bottle provides the opportunity to investigate different variables. You can construct your own vortex bottle using instructions here:   VORTEX BOTTLE 1. Making the vortex bottle is part of your research. Other things to research would be to read […]

Project Research: Primary vs. Secondary

By Janice VanCleave

Project research is the process of collecting information.  I suggest that you start with fact finding research, which is called secondary research because it is knowledge already discovered by others. These facts are found in books, magazines, software, and from knowledgeable people, such as librarians, teachers, parents, scientists, or other professionals. While it is not […]

Science Project: Paper Towel Water Absorbency Rate

By Janice VanCleave

A straight sided container with a tape scale 0-11. A folded paper towel standing in the red water in the container.

  Comparing the Water Absorbency Rate of Different Paper Towel Brands A TV advertisement  claims that Brand X paper towels are the best. You could compare the water absorbency rate of Brand X with other paper towel brands. Water absorbency rate is the amount of water absorbed in a certain amount of time. Science projects […]
