  1. This is what I learned in science. Objects that allow electricity to flow through then easily are called conductors. Dead load is the weight of the bridge. Live load is the weight of the objects which is on the bridge. Tension is a stretch or pull on an object. Compression is a push on an object. A cofferdam is built to keep water out when building a peer.

  2. A short circuit is a circuit that does no work. There many parts of a suspension bridge like the cables, hangers, towers, foundations, and anchors. A parallel circuit is a circuit that is parallel - it has two of something like a lightbulb or a fan.

  3. Ok this is some of what I have learned so far: torque is a turning force,suspension bridges have towers, hangers, cable, anchors, an approach on each side, span, and foundations. Another name for a tower is a pier. The wooden frame put under a arch bridge while it is being built is called the centering. For something to balance, the forces must be equal and opposite. The part of the bridge which you drive on is the deck. A connection of wires is called a circuit. A circuit that does no work is called a short circuit. In a series circuit if you pull one light bulb out the other(s) will go out but in a parallel circuit if you pull one light bulb out the other will stay lit.

  4. I learned.
    (1)objects that let electricity through are called conductors
    (2)the bridge is the dead load
    (3)live load is the stuff that cross the bridge
    (4)keystone is the last rock in an arch bridge
    (5)a circuit that does no work is a short circuit
    (6)a parallel circuit wears out the battery twice as fast
    (7)in a series circuit if one light bulb goes out all of them do

  5. 1. In a series circuit if you unscrew one lightbulb the whole thing goes out
    2. A keystone is the last rock put in while making an arch bridge
    3. The whole bridge itself is the DEAD load
    4. The things that cross the bridge is called the LIVE load
    5. I a parallel circuit the light goes out twice as fast because they are both BRIGHT so it wares out the battery faster.
    6. When you build an arch bridge you use a centering.

  6. I learned that short circuits can cause a house fire and it does no work.
    I also learned that there are parallel circuits.
    I also learned that series circuits have two lights or two fans on the circuit.
    I also learned that if the front of your bridge is a square it will only hold 6 books I learned that the hard way.
    I also learned that there are so many bridges in the world.
    I also learned that bridges are fun to build.
    I also learned that bridges have cables, hangers, live load, dead load, decks, foundation, towers or piers and approach.

    I LOVE SCIENCE!!!

  7. Things that I've learned about electricity...
    tension is a stretch or pull on an object, series circuit have a dim light, if one bulb goes out all bulbs go out, and not the kind of circuit you find in houses, an electromagnet is a magnet that gets it's force of attraction from an electric current,current is electricity moving through the circuit, a circuit is a connection of wires that electricity travels through, a short circuit is a circuit that does no work, can start a fire, and wears out battery, a conductor is an object that lets electricity flow through, an insulator is an object that does not let electricity flow, a parallel circuit is a circuit that houses have, both bulbs are bright, if one goes out the others stay lit, and wears out battery twice as fast, static electricity is electric charges that builds up an object instead of flowing through it as a current.

  9. Some of the things I learned ;
    a group of wires are called a circuit a short circuit is a circuit that does no work in a series circuit the lights are dim and if one goes out they all go out in a parallel circuit both bulbs are bright wears out battery twice as fast magnetism and electricity are related

  10. I learned a lot in science in the last unit. In electricity, I learned that
    1. the symbol of a lightbulb is a circle with an x in the middle of it.
    2. the symbol of a switch is an arrow
    3. the symbol of a battery is a series of lines
    4. in a series circuit, if you take a lightbulb out, the others will turn off
    Now here are some facts in the bridge unit
    1. tension is a pulling force
    2. compression is a pushing force
    3. torque is a turning force
    4. abutments push in on an arch bridge
    I learned a lot more but my blog would be so long. Good luck on the test!

  11. Some things I learned in science about electricity…

    1. A short circuit does no work
    2. gets hot/can start a fire
    3. wears out the battery
    4. A series circuit is dim
    5. if 1 goes out they both go out
    6.A parallel circuit are used in houses
    7. if one goes out the other stays lit
    8. both of the light bulbs are BRIGHT
    9. the battery wears out twice as fast
    10. electricity is fun,hard and AWESOME

    Some things I learned in science about bridges…


    1. torque is a turning force
    2. compression is pushing
    3. tension is pulling
    4. tension makes things longer
    5. compression makes things shorter

  12. A circuit that does no work is a short circuit. A circuit is a connection of wires that electricity travels through. Tension is a pulling force and compression is a pushing force. An arch bridge's strength comes from how it's curve carries weight outward in both directions to it's abutments at it's ends. A conductor is something that lets electricity pass through. An Insulator is something that does NOT let electricity pass through.

    There is much more that I do not have time to write right now.

  13. Objects that allow electricity to flow through them are called conductors. Objects that don't let electricity through them are called insulators. Dead load is the weight of a bridge. Live load is the weight on a bridge. Tension is the stretch or pull on an object. Compression is a push on an object. The wooden frame put under an arch bridge while it's being built is called the centering. The keystone is final rock put into an arch bridge. The part of the bridge you drive on is the deck. The part of the bridge which is in the ground and supports the rest of the bridge is the anchor. Another name for a bridge tower is a pier. A cofferdam is built to keep water out when building a pier under water. For something to balance the forces must be opposite and equal. A circuit that does no work is a short circuit. In a parallel circuit if one bulb is removed, the others stay lit. Torque is a turning force made by weight times distance. If an atom has 10 protons then it will have 10 electrons. The difference an abutment and an anchor is that an abutment is on an arch bridge and pushes, an anchor is on a suspension bridge and pulls. On a seesaw heavy object have to be closer to the center of the seesaw. The closer the object is to a tower the easier it is to hold up. A suspension bridge can have trusses in it. An egg is strong because it has many arches. To make a square stronger, put a piece across a corner to make a triangle in a square. The main force that pulls on structures is gravity. A parallel circuit uses more electricity from the battery than a series circuit. Electricity and magnesium are related. 8 parts on a suspicion bridge are: The approach, live load, dead load, cables, hangers, deck, span, tower (or pier), and anchor. That's all I have for today!
    SEE YOU NEXT TIME @MS.PAPADAKES'HIDEAWAY!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

  14. There are many different types of bridges. Like a suspension bridge, a beam bridge, an arch bridge, and a ton more. An arch bridge will fall down if it doesn't have its keystone which is the to piece. The main force on an arch bridge is compassion. The main force on all the bridges is gravity. A short circuit does no work witch means the electricity just keeps going around the wires and doesn't give electricity to anything. A conductor is something ( usually a metal object) that electricity can go through. A insulator is something ( usually plastic or a metal object and some other things) that electricity can't go through. A torque is a turning force. Compression is a pressing force. Tension is a pulling force. In a series circuit the light bulbs are more dim because the bulbs share the electricity. In a parallel circuit the bulbs are bright because the battery gives twice as much electricity and the battery runs out twice as fast.

  15. I have learned a lot in science and I am going to list some of the stuff that I have learned:
    a) A short circuit is a circuit that does no work
    b) Something that is on a bridge that is not a part of the structure is called the live load
    c) The whole bridge structure is called the dead load
    d) A series circuit is a circuit that has two light bulbs and they are in line on the same wire so they share the electricity and are both dim
    e) a parallel circuit has two light bulbs but they are on different wires so they don't share the electricity on the same wire so they are both bright
    f) When a bridge is under construction, a cofferdam must be used to build the support piers which is also called the tower
    g) The parts of a suspension bridge are: the deck (the road), the hangers, the cables, the foundation, the pier, the tower, the anchor, the live load, the dead load, the approach and the span

  16. A short circuit is when a circuit does no work. They are really dangerous because the electricity is going round and round and is heating up. House fires are caused by this a lot and short circuits wear out your battery twice as fast. A series circuit is if when one appliance goes out the rest do to. But on a parallel circuit if one appliance goes out the rest stay on. Now onto bridges. Every thing that was not part of the bridge when it was built is called the live load. For example a car driving on it would be a live load. Every thing that was part of the bridge when it was built is called the dead load. For example the deck was part of the bridge when it was built so it is dead load. A force that is pushing is called compression and a force that pulls is called a tension. A force that turns is called torque.

  17. A short circuit is a circuit that goes around and around and does no work. A pushing force is compression and a pulling force is tension. Every thing that is a part of the bridge is dead load and everything that goes across the bridge is live load.

  18. 1. Everything that is not the bridge is the live load like a car
    2. The bridge itself is the dead load
    3.Compression is a pushing Force
    4. Tension is a pulling force
    5. A short circuit is dangerous because the wires can heat up and cause a fire
    6. Objects that let electricity flow in them are called conductors like metal
    7. Objects that don't let electricity flow through them are called insulators like plastic
    8. Torque is a turning force
    9. A keystone is the last rock to put in while making an arch bridge
    10. A circuit is a connection of wires that electricity travels through.
