Relationship between the strength of the electromagnet(#of paperclips picked up) and the diameter of the nail
Number of Paper clips picked up by different lengths of Diameter of the nail
Treatments
(Diameter of Nail)
Number of Paper Clips picked up
Treatment 1 (2mm)
8 paperclips
Control (3mm)
14 paperclips
Treatment 2 (4mm)
19 paperclips
Treatment 3 (6mm)
23 paperclips
Hypothesis
If the diameter of the nail influences the strengths of the electromagnet. Then an increase of the diameter of the nail will cause and increase of the strength of the electromagnet. Discussion
In our experiment that we conducted, our collected data shows that the larger length of the diameter of the nail caused an increase in strength of the electromagnet. According to the graph, the increase of diameter of the nail will cause an increase of strength of the electromagnet. This reflects my hypothesis stating that the diameter of the nail influences the strengths of electromagnet. It shows a positive relationship between the diameter of the nail and the strengths of the electromagnet.
Since the number of wraps is a control variable and only forty wraps are allowed. Therefore a nail that has a larger diameter requires more wire than a nail with a smaller diameter. Since the nail and the wire is a control variable, the materials of every nail and wire conductivity will be the same. Therefore, the nail that has a larger diameter will require more wire to wrap around it. This will cause an increase in strength of electromagnet and it has equivalence to having more wraps

Introduction A greenhouse is a glass building in which plants are grown that need protection from cold weather. The natural level of greenhouse gases in our atmosphere, which keeps the planet about 30ᵒC warmer than it, would otherwise be- essential for life as we know it. Water vapour is the most important component of natural greenhouse effect. Greenhouse gasses are gas that contributes to the greenhouse effect by absorbing infrared radiation. Some of the greenhouse gasses are carbon dioxide, nitrous…

Haunted Science Lab Narrative

The haunted science lab wasn't just a name. I was the coolest kid in the seventh grade and kids like me aren't supposed to believe in things like that. We are supposed to act all tough, mature, and older than we are. That’s my least favorite part about being the coolest kid in seventh grade if i feel like messing around my friends don't want to “ruin” their reputation. No one else may believe in the haunted science lab but i sure do. It all started in sixth grade. My older sister Joe…

Unit 3 Science Lab

Science lab-Building an electroscope Observations: Discussion questions: 1. The charge on the electroscope was positive. It was positive because the rod used had a negative charge and the charge on the electroscope for induction is always opposite to the rod. 2. The charge on the electroscope was negative. It was negative because the rod used had a negative charge and the charge on the electroscope for conduction is always the same charge as the rod. 4. Charging an ebonite rod with fur and…

Science Inquiry Process Lab Report

In science class, we have been working on science inquiry process. Science inquiry has a lot of steps to make the whole process. We asked questions, made a hypothesis and we set up our experiment and gathered our data for 6 days. And ended the experiment with our conclusion. The purpose of the potato lab was to use the steps of science inquiry process to investigate a question. We did research to see what are other people's opinion for the best ways to have a potato to sprout at home, we used this…

DNA Science Lab: Review Test Essay

Reagents Used in Lab: ● Lysis Buffer: Disolves the cells’ nuclear membranes and the phospholipid bilayer, allowing for the DNA to be released ● Protease: Breaks down cellular proteins. We used protease to DESTROY DNAses and the histones. ● Cold Alcohol: to precipitate the DNA out of the solution. The DNA is less soluble in alcohol, so it WILL become visible. The human genome refers to the 46 chromosomes that are found in human cells. The difference in ?? FOOD DYE LAB Purpose:…
