INTRODUCTION TO LABORATORY EXPERIMENT AND MEASUREMENT Purpose a. To take some simple measurements to use for statistical analysis b. To learn how to use a Vernier caliper and a micrometer screw gauge. c. To learn about how straight line plots may be used to extract physical quantities by comparison of experimental data with a theoretical expression

Frog Pith Preparation

Frog Pith Preparation

+

Pithing Procedure Before the experiment, you need to render the frog insensitive to pain. Pithing is one procedure to accomplish this. Pithing will destroy the brain, which is loed between the eyes. (For some experiments, pithing will include severing the spinal cord.) Pithing is relatively painless to the frog.

Volcanic Eruption Science Project. Volcanoes erupt when magma, redhot liquid rock, seeps up through a vent in the earth. These vents can be at the top of a mountain or on a flat area. Volcanoes can even erupt underwater if there is a vent in the ocean floor. Magma is formed when part of the earth's mantle gets hot enough to melt.

The Acceleration Due to Gravity

The Acceleration Due to Gravity

+

All we need to do is drop an object through a known distance (x) and then measure how long it takes to fall (t). If we know both x and t, we can solve Equation (6) for g. g = 2x t 2 (7) Thus, by measuring the distance traveled and the time of travel for an object falling from rest, we can determine the gravitational acceleration. Procedure: 1.
