Color and appetite
This science fair project was performed to investigate the effect of the color of our surroundings on our appetite. The science fair project experiment involved placing squirrels in colored boxes and observing their daily consumption of nuts.
Tick-tock, Biological clocks!
This science fair project was conducted to find out how the biological clocks of singles and couples adjust to changes in the environment. The science experiment involved shifting daylight hours for single hamsters and paired hamsters.
What are the best places on your body to meassure your pulse?
The pulse represents the variation in blood pressure from diastole to systole. During diastole blood pressure falls, but increases after systole as the heart pumps more blood into the arteries. You feel this difference when taking your pulse. Doctors use a device called a sphygmomanometer
How does the pulse relate to the heartbeat and how does it differ when the body is in different positions?
Take your pulse at mutiple sites. Relate the pulse to heartbeat.
How to make a glass sphere microscope
Events happen in nature in many dimensions. Most of them pass unnoticed by observation because their scale is too big or too small. In fact, we would have to be giants, to follow the path of clouds over continents! And who knows how big we should be, to be able to contemplate the majestic rotations of our galaxy! On the contrary, if we were as small as an ant, we could see the amazing miniature wo
Do changes in the environment such as temperature and light affect shrimp in their choice of habitats?
In this lab, you will examine the habitat preferences of the brine shrimp, Artemia. You will use controlled experimentation to determine the thermal, pH, and light environments selected by Artemia. Based on your experience with this lab, you will design an experiment that could be used to survey other variables and other organisms.
Do boys and girls have different resting pulse rates?
The purpose of this experiment was to determine if gender in seventh graders affects resting pulse rate.
Which Apple Type Changes in Sugar Content Most After Removal From Cold Storage?
The purpose of this experiment was to measure the amount of natural sugar content change in three different types of apples over time out of cold storage. The information gained from this experiment would help people know why and which apples are changed the most in sugar content when taken out of cold storage.
The Effect of Shampoos on the Tensile Strength of Hair
The purpose of this experiment was to determine how various shampoos affect the tensile strength of human hair. The information gained from this experiment will help people know which shampoo will make their hair stronger so it won’t break off easily. Consumers will also know which brand to buy so that their hair is stronger and healthier. I think that this will be very beneficial for the ha
Build a stereoscopic microscope
Why build a microscope? The following is a guide on how to build a stereoscopic microscope. This guide allows you to assemble, at a relatively low cost, an instrument that is useful for observing natural objects such as insects, plants, minerals, fossils and flowers.
