• Middelbare school
• havo, vwo
• Leerjaar 1

Get ready:

• Your Macbook (join the lessonup)
• Your notebook
• Your textbook
• Pen 
• (highlighter)

Topic 1: Observing the World

Plan for today

• Homework check T1.5
• Theory T1.6 

• Making scientific drawings

Information:

• Week after autumn break: Microscopy

(People that do not do the microscopy LessonUp will get ''HW forgotten'')

• Week after that (15 nov): Proefwerk about Topic 1 

Homework for today:

• Answers for topic 1.5 are in the classroom
• Correct your answers in a different color (Answer wrong? write down the correct answer in the different color)
• I will call people to show me their homework (Everyone else will stay seated!)

Topic 1: Observing the World

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

Key words:

Particle

Atom

Molecule

Photosynthesis

Organism

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.

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.

Build the molecule

Go to the classroom and complete the assignment ''building molecules''. 

You have until the timer runs out.

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.

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

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

Homework:

• Complete the exercises on page E38 & E40
• Study glossaries of Topic 1 (T1.1, 1.2, 1.3, 1.4, 1.5 and 1.6)
• Do the LessonUp lesson ''Skills-How to work with microscopes'' (after autumn break)

Week after autumn break (15 nov) = Proefwerk Topic 1 (4x)

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

Prepare for scientific drawing

• Only need pencil, ruler and worksheet, everything else in the bag.

• Work in pairs (person sitting next to you)  --> but everyone makes their own drawing

• One apple for each pair!

Scientific drawing (apple)

2 apple drawings:

• Outside view
• Cross section

Grade the person next 

to you (use the rubric 

provided)

Both apple drawings + rubric should be glued in your lab journal

Homework:

• TODAY: hand in a photo of your scientific apple drawing + rubric in classroom!
• Complete the exercises on page E38 & E40
• Study glossaries of Topic 1 (T1.1, 1.2, 1.3, 1.4, 1.5 and 1.6)
• Do the LessonUp lesson ''Skills-How to work with microscopes'' (after autumn break)
