Magnetic Force (4/4-4/8)

Link

Summary:

This week we were learning about magnetic forces. A magnetic force is the power that is forming between things that are magnetic. We did a science experiment to see what can break a magnetic force. What do you think will break a magnetic force?

In the science experiment, we were testing to see what different things can break a magnetic force. We have tested a lot of objects: a shoe, paper, hand, rubber band, necklace, cardboard. But... they did not break the force.

At the end, we found out that the only thing that can break a magnetic force is space. What does that mean? Have you ever tried putting 2 magnets close together and fee them attract? Well, if you put them further apart, there is not a magnetic force anymore which means that the magnets are too weak at this point to attract.

The stronger the magnet is, the further the magnets will attract from. Some magnets are really weak, and those magnets will only attract from only a close distance.

Opposites Attract

Have you ever heard the saying "opposites attract"? Well, it is true with magnets. There is a north pole and a south pole on every magnet. The south pole is generally the positive side. If you are pointing two north pole sides together, the magnets will repel. Have you ever felt that? Sometimes the magnets are so strong that even if you force them together you will not be able to. However, if you are pointing north and south together, the sides will attract easily and it can be difficult to separate it.

Attracted to Magnets

The three elements that are most attracted to magnets are iron, cobalt, and nickel. Steel has some iron in it so it is also attracted to magnets. Does it ever happen to you when you are holding something magnetic, and then something else gets attached to it such as a paperclip? That thing that gets pulled to it is most likely made of iron, cobalt, or nickel.

SP3: Planning and Carrying out Investigations


As a group, we performed an experiment to test our hypotheses. We thought that something really thick such as a book would break a magnetic force, but we proved that we were wrong and the only thing that can stop a magnetic force is space.

Conclusion

I hope you learned something about magnetic forces today from my examples and explanations. It was really fun in class when we were trying to break the magnetic force many different ways but none worked. After that, we figured it out!

Musical Instruments and Sound- Weekly Blog (3/11-3/15)

Sound Energy - Musical Instruments by SolPass Summary We understand how sound is produced, and how sound waves can travel through different mediums, but how do musical instruments produce sound? There are hundreds of instruments in the world, producing various pitches, tones, and chords. There are three main types of instruments: wind, percussion, and string. The sound is produced differently based on the type of instrument. The first type of instrument is a string instrument. In a string instrument, the sound is created from the vibration of strings. For example, when you play guitar, you pull on the strings. As the strings vibrate, the air molecules start vibrating as well, producing sound. The next type of instruments are wind and brass instruments and are made when we blow sound into them. The shape and position of the instrument affect the overall tone and pitch. The most common kind of wind instrument is a reed instrument. Blowing on the reed causes it to vibrate, mak

The Food Chain (10/26-10/30)

This is an example of a land food chain http://www.sheppardsoftware.com/content/animals/kidscorner/foodchain/foodchain2.htm Summary: This week in class we started to learn about the food chain. We watched a video about the food chain, and then we had to answer a few questions. First you need to know that food chains always start with plants and end with animals. But remember, humans are animals. Humans are usually at the top of the food chain. But that does not means that they are always at the top, what if a lion ate the human! Then the lion would be at the top of the food chain. There are different types of food chains. If you want to see a full list then go to this website: http://examples.yourdictionary.com/examples-of-food-chains.html . In the video they talked about the ocean food chain. The ocean food chain is a food chain that happens in the ocean. Here is an example of an ocean food chain: phytoplankton (tiny little plants), get eaten by zooplankton (tiny animals

Three Sisters - Plate Tectonics (3/19 - 3/23)

https://upload.wikimedia.org/wikipedia/commons/5/5f/The-Three-Sisters-Szmurlo.jpg Summary: Do you ever wonder how some famous landforms such as mountains and islands are created? There are eight main tectonic plates on the surface of the Earth that make up the lithosphere. The movement of these plates is what causes landforms such as mountains and more. The three sisters mountains in Oregon were created by the movement of tectonic plates over a very long period of time. The three sisters mountains were created by the collision of subduction zones. Subduction zones are a type of convergent boundary where one of the places contains oceanic crust, and the other contains continental crust. The two plates collide, causing the oceanic crust to move downwards into the asthenosphere. The collision that created the three sisters mountains was between the Juan de Fuca tectonic plate and the North American tectonic plate. These amazing landforms were also created by land erosion.
