Velocity, acceleration, and inertia definitely affected my egg in a negative way. This is what my egg project looked like the basic: a lot of things went wrong with this project. Another thing is that there was too much glue that made up the project so it added mass to the project which is exactly what i didn?t want. Here is a rough example of what i would have done next time side view: this i believe would be more effective because this kind of looks like other peoples whose egg survived.

Critical Analysis of a Qualitative Research Paper

Velocity is the quantity that designates how fast and in what direction a point is moving. An opposition any agency attempts to put a property of a body by virtue in, if its moving, to change the magnitude or direction of its velocity is inertia. The point when the egg was being dropped, velocity designated how fast and which direction the project was moving.

My egg drop project definitely had a direction and magnitude i didn?t want it to have. Your project will have two parts: first you must write an essay with three body paragraphs. The first has to explain what pressure is, how it is created, measured and calculated.

The second paragraph will include examples and explanations of where increased pressure and decreased pressure is found and used in the real world. The third paragraph will be a description and explanation of the egg drop device, including their rational for how they designed their device and a picture/plan for how the device will be built. The devices will be built to handle the pressure on an egg when it is dropped from a height of 3.5 meters. The supplies you will have are: remember that nothing can be taped or glued to the egg, but you want, you can build your device around your egg. You will not be able to start the construction of your project until you have done a sufficient job completing your essay. You will have one class on wednesday, two classes on thursday, two classes on monday and two classes on tuesday.

project 3: the egg drop experiment: a hands on investigative activity background on investigative activities student participation in hands on investigative activities or laboratory activities that develop inquiry and intellectual skills is an essential component of meaningful instruction. Investigative activities give students an opportunity to appreciate the spirit of science and promote understanding of the nature of learning. From a constructivist perspective, investigations can allow students to pursue learning autonomously, and offer a variety of multisensory experiences, though sometimes these activities fail to go beyond cookbook activities.

Furthermore, the evidence suggests that investigative activities fall short of achieving the potential to enhance student learning with understanding. as a result, most teachers today have not fully incorporated investigative activities as a means of allowing students to solve problems and thereby construct knowledge of science. The classic egg drop experiment has been a standard in science instruction for many years. Essentially, students are asked to construct some type of container that will keep a raw egg from cracking when dropped from ever increasing elevations. But with some further thought, this activity can be both engaging and completely in accordance with the national science education standards developed by the national research council in 1995. National science education standards with this activity, students will gain the ability to design a product a container , evaluate the product, and communicate the process of design modification. The problem or, more appropriately, the challenge in this scenario is to drop an egg from a specified height usually in increasing incremental steps from 1 story to 3 stories and ensure that it remains unharmed.

The egg may be considered to be an analogical representation of some precious cargo, such as a human being, that ideally would not be harmed upon reentry into the atmosphere from space. For protection, the egg can be encased within a regular size quart container of milk or orange juice original liquid removed. Generally, parachute devices are usually discouraged initially but can be incorporated at the discretion of the instructor if desired. Students should be encouraged to experiment with a number of different designs for this task. The project assignment is to keep a record field journal of:

the various designs rationales for the designs any experiments performed subsequent to the actual egg drop in this manner, we are attempting to record the developmental process that takes place over a series of a couple of weeks as students devise designs and evaluate their effectiveness.

As the students' hands on experimentation develops, teachers must be conscious of instructional opportunities that will present themselves and warrant benchmark lessons. A benchmark lesson is instruction that aims to raise the general level of subject matter knowledge of the entire class. In the egg drop project, benchmarks may include the interrelationships between free fall, force, and gravity. Evaluation of the field journals can be made at various points during the unit or the teacher can have groups present their initial findings via some type of presentation demonstration, videotape, multimedia. As opposed to cookbook exercises in which students follow prescribed procedures, effective laboratory and investigative activities can be designed to encourage opportunities for:

experimentation prediction independent interpretation laboratory activities can also foster learning and student enthusiasm when they are geared to students' needs and can give students the satisfaction of finding out that they can overcome challenges. Recent advances in science education suggest that experiments in laboratories should be written according to several criteria:

Experiments in science should also include topics for which current knowledge is incomplete or not understood even by scientists. Students should be required to prepare in advance, in their notebooks or journals, a plan for how to proceed with the experiments, rather than using manuals.

even with these criteria, there remain a number of challenges to investigative instruction in the middle school science classroom.

Clarifying the role of the investigation in developing inquiry skills and determining the value that the investigation has in developing an understanding of the subject content. Students who do not yet understand the principles of the subject area will be at a disadvantage when they are supposed to observe and identify the intended phenomena of a particular investigation. Investigative activities have historically been seen as auxiliary and as a dispensable aspect of the traditional classroom by teachers, curriculum designers, and policymakers. A number of different groups can be set up to search for initial ways of approaching this problem.
