WORMS MAKING FOR FREEDOM

October 20th 2019 and after a week of worry I decided it was finally time to investigate the wormeries and see if the kilogram of worms were still with us. I am finding the stress and responsibility of these hard to take.

My plan, empty each wormery on an old piece of vinyl, investigate what is there and remake each one as they’ll be alone for a week. This was made more difficult as a very cute and friendly robin has been following me around the garden for the last fortnight and passes behind you after you’ve moved any piece of garden soil.

It was really heartwarming to see oodles of big fat juicy worms fall onto the vinyl. They weren’t moving much but were certainly a good size and huddled together in some big piles. The bottom of the blue wormery was quite wet, this was the one with no drainage. The paper had gone slimy and the potato skins were still undigested. Katrina, your McDonald’s straw is still there, but I think the bacteria might be thinking about working on it. So a new cardboard base, screwed up paper, the worms and then some partially digested compost. Lid back on and ready for off. The robin was flapping around so I posted a guard at the door.

Even the pink wormery had worms but the bottom was slimy with sand and paper- whoops I forgot to take a photo of this. So I’ve made up the box, with fresh cardboard and moved some of the worms from the blue box to the pink one and added more partially digested leaf mould / compost. Lid back on.

I was in two minds as to whether I ought to hold out one for the robin as a treat, but then Miss Crozier came to mind and I couldn’t bear to sacrifice one of the little cuties. Everything back in order, I stepped inside to get cleaned up and then remembered I ought to take a photo of the robin. It was then I noticed the escapees. I’ve no idea where they came from but at least 10 were making their way to freedom down the cracks in the paving and across the slabs. I couldn’t pull one up (see photos). If the robin gets you it isn’t my fault as I did give you a little tug to put you back.

So to the Sophie and Hollie- I’ve not killed them and they ought to be ready for you to get them through the winter next week!

Sorry the photos are in the wrong order with the escapees first.

Worms move in!

Well, Wednesday 4th September one group in the Climate Catastrophe Group built their wormery. We are going to look into recycling of food and break down of fruit and vegetables. Worms do create greenhouse gases, but play an important part in maintaining the soil, which has taken a hammering over the last 60 years.

Unfortunately the worms arrived late on Thursday 5th September and had to be in the wormery before the weekend. The students hadn’t quite finished the wormery, so many came up during their lunch break and helped get the worms a temporary start. Our biggest concern is the amount of moisture that we need. The wormery isn’t a draining one, so getting the air and moisture levels is important. We also had to put all the worms in the one box as the second box wasn’t ready.

Let’s hope the worms make it through the weekend. The suspense is terrible and the temperature this weekend was pretty warm, the first dry weekend in four weeks- drat.

Climate change

In these posts I’ll try to add content about the most important topic facing our world. I will only use evidence based Science to make my points.

Having Mr Physics on the case helps as he’s been involved in measuring this stuff from the late 1980s to the beginning of the twenty first century.

Here is the definitive link for all things Climate Change, ask an adult if it is too hard.

TermMeaning
At rest not moving, the object is stationary. It is not the same word as pens and pencils which are stationery!
Average Speedthe distance of the whole journey divided by the time for the whole journey.
Braking Distancedistance the vehicle will travel as the brakes are applied.
Displacementhow far you have travelled in a straight line. We would say “as the crow flies” You must quote a direction when writing down a displacement.
Distanceis how far you have travelled. It is another name for length.
Dynamicsthe part of mechanics dealing with Forces.
Instantaneous Speedthe speed at which you are travelling over a very short distance.
KinematicsKinematics means the part of mechanics dealing with motion, speed, acceleration etc
MechanicsMechanics is the branch of Physics dealing with motion (how things move)
Reaction Time the time it takes a person to react to a situation and understand the dangers.
ScalarA quantity that is fully described by a value and unit
Speed is the distance travelled in unit time.
Stopping Distancestopping distance= thinking distance + braking distance .
Thinking distanceis the distance a vehicle will travel in the time it takes you to react to the situation.
TimeTime- is how long your journey took. It is measured in seconds or during our road safety topic hours. We never write sec or secs in Physics to mean seconds
Uniform Speedwhen your speed isn’t changing, it remains constant.
VectorA quantity that is fully described by a value, unit and direction
Velocitydisplacement covered during the journey divided by the time taken. You must quote a direction when writing down a velocity

NEW TASK

1.      Watch the videos

https://www.youtube.com/watch?v=Xo3KBoEMDEo

https://www.youtube.com/watch?v=O22zcaELpaA

https://www.youtube.com/watch?v=hBbxznjLrL4&t=48s

2.      Go slide 108 on the S2 SPEED powerpoint on DISPLACEMENT and VELOCITY

https://www.mrsphysics.co.uk/bge/s2-road-safety/s2-speed-2020-final-3/  work from slides 108- 124, you can do the practical if you have a playmat, car and timer

3.      Complete the sheet on Displacement and Velocity https://www.mrsphysics.co.uk/bge/wp-content/uploads/2018/02/Velocity-sheet-2018.pdf.

4.       Answer the Quiz on Displacement and Velocity in Teams.

ALTERNATIVE

5.      OR complete a SPEEDING SURVEY https://www.mrsphysics.co.uk/bge/wp-content/uploads/2016/08/speed.pdf  (page 6) Make a survey after asking your family and friends who drive, but remembering to keep your distance!

This will require some explaining so are you ready.

1)      You are going to go for a walk, or run as part of your daily exercise.

2)      Count the number of steps that you do and keep walking until you can see a direct and safe line to your home

3)      Record the number of steps that you have taken.

4)      When you can see a direct and safe line to your home or starting point stop, face home/ your starting point and walk directly to your starting point. If you have a compass look at the direction you are travelling in.

5)      Record the number of steps that it took to get home.

6)      The number of steps you took on the way out is your DISTANCE TRAVELLED, the number of steps back is your DISPLACEMENT.

7)      Draw that as a sketch on your notes of paper.

8)      Repeat this task but try to time how long it took you to walk out to the place where you stopped. Record the steps and the time it took to get there. This could be in seconds/ minutes/ hours or elephants (nearly seconds).

9)      Walk back again counting the number of steps, but not timing it.

10)   Speed = number of steps out/time to get there

11)   Velocity = number of steps to get back/ time to get there and a direction.

12)   Don’t forget to add you units even if this is in steps/elephant

13)   Can you try to explain, Distance/ Displacement/ Speed and Velocity?

First Week of Lockdown

Work through the Speed Powerpoint that will be on TEAMS and on https://www.mrsphysics.co.uk/bge/transport-2018/

Check the work on TEAMS and on here. We will set an online ASSESSMENT at the end of APRIL.

IN addition try some of the RESEARCH TASKS below

Do  NOT complete the AIR BAG practical until the FULL RISK ASSESSMENT has been uploaded.

 

By the Easter Holidays you should have covered

  • Road Safety and Road Signs
  • Average Speed
  • Instantaneous speed
  • Reaction Time
  • Thinking Distance, Braking Distance and Stopping distance

 

Research Tasks-

Take a note for your SALs Booklets

Welcome to the Lockerbie Academy Additional Work Sheet. Hopefully you’ll be working your way through the power point on TRANSPORT 1 -SPEED, which I am in the middle of updating.

There are plenty of speed distance time calculations you can do and I’ll add work on calculators.

Why don’t you make some suggestions about where Physics and Road Safety meet?

Choose 1 or more of the following 8 tasks to complete. Don’t complete the practical until I’ve uploaded the full risk assessment.

1.      Road Safety Statistics

Are you bored already and need something to get your teeth into?

        https://roadtraffic.dft.gov.uk/custom-downloads/road-accidents

https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/848485/road-casualties-year-ending-june-2019.pdf

Why don’t you select a group of road users, years, speed limits, type of road users, country, Region and research to see if you can find out some of the following

  1. a) On which roads do most road deaths occur?
  2. b) Which group of road user have the highest death toll?
  3. c) Which part of Great Britain has the highest injuries and why?
  4. d) Why are most deaths on roads with speed limits of 21-30 mph?
  5. e) Are there differences between male and female drivers? Are there enough details for you to say who is a safer driver?

Ask yourself some questions to answer

Make sure you try to show your results in a table, graph or pie chart. Why not have a play with EXCEL? I’ll try to update the Excel for 2016 a.s.a.p. but I’ve other things to do first.

2.      Road Signs

How about  trying to learn your road signs?

https://highwaycodetest.co.uk/road-traffic-signs/

If you can’t face doing 157 questions try some of these tests.

https://www.driving-school-beckenham.co.uk/mocktheory5.html

Road and traffic signs 2

3.      Reaction Time When Driving

If you are doing this task you’ll need to graph your results. Do your reactions improve as you play the game? Can you get the scores of your friends and plot data from you and your friends. Do older students have better reactions?

https://www.justpark.com/creative/reaction-time-test/

https://www.humanbenchmark.com/dashboard/reactiontime

4.      SPEED SURVEY

I’ll upload the diagrams when I can get a better quality image.

5.      DRIVER ALERTNESS / PERCEPTION

Will you be an alert driver? Can you spot and react to the hazards. Write a report about what you found out.

https://www.driving-test-success.com/theory-test-alertness/theory-test-alertness.htm

https://www.theory-test-online.co.uk/free-hazard-perception-test-demo.htm

Alertness study test (with hints)

 

6.      Practice Excel

Can you plot this data in EXCEL in a graph? Make it a stacked graph. Search online for a better  diagram.

7.      Road Safety Analysis

Look at the road statistics below. State what you can see in the data and can you give reasons for the massive changes since 1964 in the numbers of road deaths, injuries and severe injuries.

 

8.      AIR BAG PRACTICAL

If you have this material in the house you might want to try this, but you ought to wear googles and you MUST check with an adult before completing.  You’ll need a tray underneath as this could make rather a big mess.
