tuning fork lab

Guiding Question: How does the density of a material affect the properties of sound travelling from a tuning fork?

Hypothesis: I think the sound will travel slower through more dense material.

Materials:
Tuning fork
table
door
chair


Procedure:
1. Thought of which materials to use
2. We got a tuning fork
3. Banged it on the table to see how the sounds were
4. Banged it on the door to see hoe the sounds were
5. Banged it on the chair to see how the sound were
6. Wrote our analyzes

Conclusion: The sound of the table was the deepest of all. The door had a higher sound because f the material it was made of. The Chair had a quiet sound. The thing that was interesting is that all of them had long sounds for some reason. I would want to know why the lenght of the sounds were all the same.

Further Inquiry: If i could change this experiment i would have used different tuning forks. And maybe also change the materials we used.

Properties of sound lab

1cm= shortest sound
2cm= short sound
3cm= middle sound
4cm= fast sound
5cm= fastest sound

Earthquake safty

During an earthquake you should drop, cover and hold. Here is how to do it.

MY ROOM

The safest place in my room would probably be under my desk. my bed wouldnt be that good beacuse it's very old and it has broken down already a few times. If i was sleaping during an earthquake, i would probably die beacuse my bed is right next to a big window. I also have unstable shelves in my room. My closet it very safe to. it is atached to the top of the cealing.
But the worst thing of all it that the balcony of my parents is the roof of my room.

MY BROTHER'S ROOM

His room has big window's too. the safest place in his room would probably be under his table, it's very stable. His bed doesn't have any space underneath. His bed is also next to a very big. window which could fall on him. His closet is just like mine to, they are both attached to the roof of our bed rooms, but being in the closet inst the safest place to be in. But the worst thing of all it that the balcony of my parents is the roof of his room, just like mine.

MY SISTER'S ROOM

My sister's room is not that safe, the most safest place would probably be the windows. She has really small windows. she doesn't have any where to go and stay safe in her room. She has too bed's. One is pretty safe but it doesn't have a hole at the bottom to go in and hide. Her other bed does but it's not stable so it would fall on her. the safest place in her room would probably be the doorway.

MY YOUNGEST BROTHER'S ROOM

His bed doesn't have space to go under. His desk has wheels so it's not safe either, his bed is not next to a window or under a light. His room is probably the safest of all in my house.

MY PARENT'S ROOM

my parents room is on the top floor, so they have the best place to stay safe in. There bed it under huge pictures, and that is not very safe. there shelves are all atached and the pictures are too. Their bathroom is safe to, all liquids are safe secured. Their safest place to be in is probably just their room, they don't have any where to go.

MAKE SURE NOT TO HAVE THESE OBJECTS NEAR YOU DURING AN EARTHQUAKE OR IN THE NIGHT

Tsunami Essay

Tsunami


A violent submarine volcanic eruption can create enough force to uplift the water and generate a tsunami. Generally, tsunamis formed by submarine landslides and volcanic eruptions dissipate quickly and rarely effect coastlines unlike the Pacific-wide tsunamis caused by earthquakes. Around the Pacific Ocean, denser oceanic plates slip under continental plates is a process known as subduction. Subduction earthquakes are particularly effective in creating tsunamis.Tsunamis differ from ordinary wind concentrated waves and are sometimes incorrectly called "tidal waves."

As tsunamis near the shoreline and shallow water, the speed decreases. The energy contained in the tsunami, which is dependent on both wave speed and height remains constant. These tsunamis have great erosion potential, stripping beach sand that may have taken years to accumulate, and destroy coastal vegetation. They are capable of flooding hundreds of meters inland past the typical high water level, and the fast moving water can crush homes and other coastal structure.

Through out history there have been numerous examples of the massive destruction caused by tsunamis. One tragedy occurred in Prince William Sound, Alaska, in 1964. On March 27, Good Friday, a massive tsunami was formed after an earthquake measuring 8.6 on the Richter scale had taken place. The tsunami reached 40 feet in height and caused mass destruction that lead to the death of many of the Alaskan people. The destruction caused 107 deaths and 84 million dollars in damages.
