  • 1.1 Observing
  • 1.2 Working in the lab
  • 1.3 Density
  • 1.4 Hearing sound
  • 1.5 Light and color 

Slide 4 - Tekstslide

1.1  Properties of substances
examples of properties are:
  • color
  • phase at room temperature (liquid, gas or solid)
  • smell
  • taste
  • appearance

Slide 6 - Tekstslide

1.2 What is the meaning
of this safety symbol?
A
Toxic
B
Danger for the environment
C
Health hazard
D
Harmful/Irritant

Slide 7 - Quizvraag

1.3  Density
The unity of density is g/cm³ or g/mL

Density = mass / volume                           


/100                                                       /100                     so:   4g/mL
Mass
Volume
400g
100mL
4g
1mL

Slide 8 - Tekstslide

1.3 A box has the following measurement:
mass = 132 g & volume = 12 cm³
What is the density? (use your calculator)

Slide 9 - Open vraag

1.3  Density


/12                                                       /12                     so:   11g/cm³
Mass
Volume
132g
12cm³
11g
1cm³

Slide 10 - Tekstslide

1.4 Hearing sound

Slide 11 - Tekstslide

1.5 How do we see color?
The human eye sees color when light bounces (reflects) off an object and goes into our eye. The color of light that gets reflected is the color that we see.  

All other colors of light get 
absorbed by the object so that 
we don’t see them.

Slide 12 - Tekstslide

1.5 A Blue light shines on a green grass.
What color grass do you see?
A
Blue
B
Green
C
White
D
Black

Slide 15 - Tekstslide

Learning Goals:
  • I know the difference between an atom, molecule or particle 
  • I can explain what atoms are in a molecule based on their formula
  • I can explain the process of photosynthesis and know the chemical equation
  • I know the parts of the plant cell and can label them on a diagram

Slide 16 - Tekstslide

Key words:
Particle
Atom
Molecule
Photosynthesis
Organism

Slide 17 - Tekstslide

Looking at different levels
Macroscopic level is what you can see with the naked eye. Microscopic level we need tools like a microscope to see.

Slide 18 - Tekstslide

Particles vs molecules vs atoms
Particle is a general term for a small piece of matter.

An atom is the smallest particle of a substance that still has the properties of the substance.

A molecule is formed when atoms 
are bonded together to form a 
different substance.

Slide 19 - Tekstslide

Build the molecule
Go to the classroom and complete the assignment ''building molecules''



You have until the timer runs out.
timer
10:00

Slide 20 - Tekstslide

Building bigger molecules

Small molecules can be combined into bigger molecules. Energy is needed to build these molecules.

A good example is photosynthesis in plants.

With photosynthesis plants use water from the soil and carbon dioxide from the air to build sugar.


Slide 21 - Tekstslide

Photosynthesis
In photosynthesis the sugar that is built is called glucose. The energy that is needed for building comes from the sunlight.


We can write this 
in a chemical
equation

Slide 22 - Tekstslide

Slide 23 - Video

Plant cell
Nucleus: controls the cell
Cell wall: shapes the cell
Cell membrane: controls the 
contents of the cell
Cytoplasm: inside of the cell
Vacuole: storage bag
Chloroplasts: photosynthesis

Slide 24 - Tekstslide

vacuole
cell wall
cytoplasm
ribosome
cell membrane

Slide 25 - Sleepvraag

Slide 26 - Video

Scientific drawing
Goal: to show the structure of what you see
Important:

  • No sketching/coloring/shading: only outlines!
  • Only draw what you see
  • Everything with pencil, no pens

Slide 27 - Tekstslide

Slide 28 - Tekstslide

Prepare for microscopy
  • Only need pencil, ruler and notebook, everything else in the bag, bag in front of the room
  • Place the tables like this:



  • Work in pairs  --> but everyone makes their own drawing

Slide 29 - Tekstslide

Microscopy draw plant cell
Microscopes are expensive (250+ euro) so make sure you use them carefully

  • One person can grab the microscope
  • Want to go to another magnification, ask me or the TOA
  • Make a drawing of the plant cell (think of the drawing rules)

Slide 30 - Tekstslide

Learning Goals:
  • I know the difference between an atom, molecule or particle 
  • I can explain what atoms are in a molecule based on their formula
  • I can explain the process of photosynthesis and know the chemical equation
  • I know the parts of the plant cell and can label them on a diagram
