I know you have been working hard to prepare for your science testabout structures and electricity. Impress me with your knowledge! Write at least three sentences explaining what you know.
Some of the facts that learned are...... Conductors let electricity flow thought easily. A suspension bridge can have trusses in them. electricity and magnetism are related. When building triangles are stronger than squares.
*4 circuits are: Simple circuit, short circuit, series circuit, parallel circuit. *A conductor is a material that lets electricity through, an insulator is a material that does not let electricity through. *Static electricity is an electric charge that builds up on an object instead of flowing though it as a current. *A foundation is part of a bridge that is on the ground and supports the rest of the bridge. *The centering is a wooden frame under an arch bridge during construction. Study hard, Abby
*dead load is the weight of the bridge *tension is a stretch or pull on an object *the keystone is the final rock put into an arch bridge * another name for a bridge tower is a pier * compression is a push on an object
About the short circuit: It does no work And it could make a fire About the series circuit: If you remove a bulb, the others will go out, And a bulb is brighter alone and dimer with others About the parallel circuit: It is brighter than the series circuit, If you unscrew a lightbulb the others stay lit, And it is the best circuit for a house Some facts about bridges: -The dead load is the weight of the bridge -The Live load id the weight of the objects that cross the bridge -Tension is a stretch or pull on an object -Compression is the push on an object -Triangles are much stronger than squares -A cofferdam is built to keep water out when building a pier under water, -And the part of the bridge you drive on is the deck
I learned in science that -the centering is what they put under a arch bridge while they are building it. -touque is a turning force caused by weight and distance -the dead load is the weight of the brigde -the live load is the weight of objects on the bridge -a cofferdam keeps water out when building a pier underwater
In science, I learned that a circuit is a connection of wires that electricity travels through. An Insulator is an object that doesn't let electricity travel through it. A Conductor is an object that lets electricity travel through it. An electromagnet is a magnet that gets its force of attraction from an electric current. A current is electricity moving through a circuit. I also learned that to build a strong bridge, you most likely will have trusses in/on it or arches. Some bridges such as the suspension bridge are in lots of tension. Arches in arch bridges are being compressed. Tension is a pull and compression is a push. They are all forces. Another force is torque. Torque is a turning force caused by weight times distance.
This semester in science I learned... *If a light in a series goes out the rest of the lights go out *An abutment holds up the ends of an arch,truss, or beam bridge *There is seven neutrons,protons, and seven electrons in Nitrogen
I know that a pier is the part of the bridge that goes into the ground to support the bridge. I know that the sign for the light bulb is a 0 with an x in it. I know that live load is the stuff that goes on the bridge like cars or people and dead load is the weight of the bridge itself.
I know that the center stone helps the bridge stay. And that a simple cercet doesn't work. And that the cars bikes or people on a bridg are called the live load.
If alight on a parallel circuit goes out the others will stay on. Triangles are stronger than squares. all bridges can have arches.
ReplyDeleteSome of the facts that learned are......
ReplyDeleteConductors let electricity flow thought easily.
A suspension bridge can have trusses in them.
electricity and magnetism are related.
When building triangles are stronger than squares.
I know that short circuits are dangerous because they get hot. Compression makes things shorter. Tension makes things longer.
ReplyDelete*4 circuits are: Simple circuit, short circuit, series circuit, parallel circuit.

*dead load is the weight of the bridge
ReplyDelete*tension is a stretch or pull on an object
*the keystone is the final rock put into an arch bridge

* compression is a push on an object
About the short circuit:
ReplyDeleteIt does no work
And it could make a fire
About the series circuit:
If you remove a bulb, the others will go out,
And a bulb is brighter alone and dimer with others
About the parallel circuit:
It is brighter than the series circuit,
If you unscrew a lightbulb the others stay lit,
And it is the best circuit for a house
Some facts about bridges:
-The dead load is the weight of the bridge
-The Live load id the weight of the objects that cross the bridge
-Tension is a stretch or pull on an object
-Compression is the push on an object
-Triangles are much stronger than squares
-A cofferdam is built to keep water out when building a pier under water,
-And the part of the bridge you drive on is the deck
wow claire that's a lot of facts

ReplyDeleteI learned in science that
ReplyDelete-the centering is what they put under a arch bridge while they are building it.
-touque is a turning force caused by weight and distance
-the dead load is the weight of the brigde
-the live load is the weight of objects on the bridge
-a cofferdam keeps water out when building a pier underwater
I learned that..
ReplyDelete∙ A keystone is the last thing they put in a arch bridge
∙ Most houses have copper wiring
∙ Most houses are on parallel circuits

ReplyDeleteI learned that..........
ReplyDelete- If you have 7 electrons that you will probably have 7 protons
- that the difference between an anchor and a abuttmance is that an anchor pulls down on a bridge and a abuttmance pushes on a bridge
-that the first orbit in an atom can hold 2 nucleus the second can hold 8 and the third can hold 18

I know that com"press"ion is a push and that tension is a pull. A triangle is stronger than a square. A short circuit is a circuit that does no work.
ReplyDeleteI know that it has to be a complete seercket to light up. And I also no that arch breg has a butmint. And i also no that serec secket wecks
ReplyDelete.

ReplyDeleteI learned that
ReplyDelete- dead load is the weight of the bridge
- live load is the weight of the moving objects on the bridge
- the centering is what holds up a arch bridge when it is beeing built
