Ohm's Law P8

Today we're going to start working on the electricity assignment for physics.  Complete the following on paper, then hand it in with a plastic pocket:

  1. Draw a circuit diagram with the parts listed on the assignment sheet. Use the symbols as shown on this page.
  2. Use some photos from the shared area to show how different circuits are made (copy and paste these into a word document).
  3. Write down the equation from this interactive, then use it to solve the first 3 questions that follow. Write the working out as well as the answers.
Make sure you name all your sheets and keep them in the plastic pocket you are given.

Ohm's Law

Today we're going to get ready for teh next assignment which we'll complete in class next week. Answer the following in yoru books:
  1. What is resistance in a circuit?
  2. Copy Ohm's Law into your books, including the units.
  3. What are 2 things that affect the current in a circuit? (Use the image above)
  4. Draw the symbols for a battery, light bulb, ammeter and voltmeter
  5. What do series and parallel circuits mean?
  6. How do ammeters get connected to a circuit?
  7. Show what a voltmeter connected to a circuit should look like using circuit symbols (use the link above):
  8. What is the unit for resistance?
  9. How could you calculate the resistance in a circuit?
  10. Try this activity, or try and complete the one from last week!

Electricity

The next assignment will be on electricity. Answer these questions in your books:
  1. What particles move to create electricity?
  2. Are electrons positive or negative?
  3. What is static electricity?
  4. Watch this video. How can static electricity be dangerous?
  5. Watch this animation. What does current measure?
  6. What does voltage measure? Use the link above.
  7. List three ways that electricity can be generated:
  8. What are some problems associated with using fossil fueals like coal to produce electricity? Use the link above:
  9. Try this activity.  What charges attract each other? What charges repel each other?
  10. If you have time, try and build a city using less fossil fuels.

Science activities

I was hoping to do a practical today, but couldn't book a room where the gas worked. Try these activities looking at what we've covered so far this year -

  • Physics skate park - What types of energy can you see?
  • Thingdom - What gets randomly given to offspring when the things reproduce?
  • There are lots of good activities on this link, try whatever you like.
  • In this game, you have to build a city that saves energy.
  • In Pandemic, you play as a disease and have to infect everybody in the world!
  • There are also lots of activities here to do with the human body.
You can also watch any of the videos posted in this site if you want to.

Energy

Today we're going to be starting the next assignment topic - energy.  Answer the following in your books:

  1. What is energy?
  2. Name two different types of energy:
  3. Can energy ever be created or destroyed? What can happen to it?
  4. What happens to the atoms in this metal bar when you heat it?
  5. What is the chemical energy in the methane being converted to here? Try and name two types of energy:                                                                                   
  6. What does  a sankey diagram look like?
  7. For a light bulb (at the bottom of this page), what is most of it's energy transferred to?
  8. Use the activity on this link, explaining when the skater has the most potential energy and when they have the most kinetic energy.

Physics P3 and P4

Today we'll be finishing and printing the powerpoint from yesterday.  Once Mr. Cole has checked yours, you can print it and put it in a plastic pocket with your name on the assignment sheet.

Next, answer these questions in your books about the bubbles for tomorrow.


  1. What is methane?
  2. What two elements make it up? Use the picture below to help:
  3. Watch the video below.  What are the three sides of the fire triangle here?
  4. Is the explosion here exothermic or endothermic?
  5. Use the bottom of the link from question 4 to explain what happens when you add sodium hydroxide to hydrochloric acid.
  6. Why can water absorb a lot of heat
  7. Why do you think it will be important to cover your hands in water tomorrow before holding burning methane bubbles?                                                                                               

Physics P3 and P4

Today we're starting the first assignment for physics.  You will need to work in a powerpoint, which we will print off later. Questions 1, 2, and 3 are for P3, 4 and 5 are for P4.

  1. Find a good image for the electromagnetic spectrum, and copy it into the middle of your slide. Find something like the ones below with different waves labelled would be good:                                                                                        
  2. Use this link to briefly explain what 5 of the waves are used for, eg. 'microwaves are used for cooking.' Write these in text boxes with lines to where the waves are in the spectrum.
  3. Copy and complete this sentence - Radio waves have a high wavelength and a low frequency, while gamma rays have a high                and a             wavelength. Use this page to help if you aren't sure.
  4. Use this page to explain what types of ionizing radiation there are, and what it can do to cells in our bodies.
  5. Explain what makes up the three types of ionizing radiation, using a table like this one:
    Radiation:
    Made of:
    Alpha

    Beta

    Gamma
