Microscope Fun

We had a great time learning all about microscopes and cells this week.  Please see here for our other microscope introduction and here for the virtual labs and cell rap!

Here is a video taken with my camera through the microscope!  WOW!  If you look closely you can see the little organisms swimming around.

I put together 13 different stations for the kids to explore.  

Making a wet mount of the letter "e"

This was just for fun!

Looking at pond water on the TV microscope

Pond water under the microscope.  See them swim in the video above!

Looking at onion cells - little bricks!

Animal cells

Plant cells

My cell name and function matching activity.

More plant and even bee cells!

Photos labo lumiere

Voici les photos des labos de lumière!!

Here are all the photos from our light lab.  It was a WONDERFUL day!  I loved seeing you all discovering new ideas about light and coming up with your own observtions. If you have any pictures to share please email me them.

Light of my life

We have been learning all about light and optics this unit and will be having a HUGE lab day next week.  In the mean time we have done a few activities that are really fun and help bring the physics of light to life!

Looking at various light sources through a diffraction gradient makes a variety of spectra.

LED

Fluourcent

Incandescent

We also learnt about how green, blue, and red are the primary colours of light (just like your TV pixels) and when you mix them you get white ... well sort of.

Go with the flow

Yesterday we learnt about flow rate and viscosity.  In order to demonstrate the flow rate of a variety of fluids without making a huge mess you can just do this quick demo.  Place a marble inside a test tube and fill it with a fluid and cap it off with a cork and tape it down.  Repeat for a variety of fluids.  Then race them!  It took months for the marble in the molasses to get to the bottom!

Separation

Earlier this week the grade 8s did a fun lab all about separating mixtures.  There were 6 stations with a variety of techniques from chromatography, distillation, evaporation, filtering, magnets and more!

INTRODUCTION À LA MICROSCOPE

1.      Décrivez comment transporter une microscope.

1. Un main sur la potence/bras

2. Un main sur la base

2.      Décrivez comment de trouver le mise au point (“focus”) d’un image sur la lamelle

1.  Placez la LAME sur la platine (en bas) avec le spécimen au centre

2.  Mettez les valets aux cotes de la lame pour tenir en place

3.  Utilise l’objectif la plus faible (4x)

4. Utilise la vis macrométrique pour trouver l’image

5. Utilise la vis micrométrique pour faire l’image plus claire

3.      Décrivez comment préparer un montage humide

1.  Mis une goute d’eau sur une lame propre

2.  Utiliser un scalpel ou pince pour placer le spécimen sur la goute

3.  Ajouter un autre goute d’eau

4.  Prend une lamelle par les cotes et placez-la pour qu’elle forme un angle de 45 dégrées avec la surface de la lame

5.  Baisser lentement la lamelle avec une probe ou crayon

4.      Comment est-ce que l’image de l’objet que tu observe change quand tu le regard par une microscope?   À l’envers et renverser!

Chris Hadfield is my hero

This school year we will be doing a lot of work on the scientific method and using technology in our class.  With that in mind we are also going to do our best to see if we can convince the CSA and my hero, Chris Hadfield, to Skype or (OMG!  PLEASE!) come to the school.  We will shoot for the stars and still be happy to land among the clouds!

Chris Hadfield has opened up the universe to the entire world!  I spent many morning last winter/spring waiting for my twitter feed for him to say "Good Morning Earth!" and show us some of the amazing things he has to share.  His photos and perspective on the earth made me feel like we are all in "it" together.  His brand of humour,  music, and science is exactly what I love about being a science teacher!  So we will figure out how to apply space sciences, the scientific method and experimental design, and Commander Chris Hadfield to our studies of the environment, plants, cells, the earth, chemistry, heat, water, architecture and physics, and so much more!  I can't wait!

More details and the method to my madness TBA!

See my other blog post about him for more cool links and videos!
