Science: Lesson 7

Get Ready:

• Textbook
• Notebook
• Macbook
• Google Classroom
• Kwizl
• Lessonup

Plan for today: 

1. Check your homework. (check your homework for mistakes and discuss this with your group members.)
2. Start Topic 1.6. (Read the text, take down new notes and get instructions for upcoming lessons).
3. Microscope time. (Working in the lab to prepare a video).

LSN 7-1.6: Observing Microscopically 

• 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

p. 38-42

Keywords:

• micro
• particle
• atom
• molecule
• photosynthesis
• organisms
• cell wall
• cell membrane
• vacuole
• nucleus
• cytoplasm
• chloroplast

p. 38-42

Levels

Macroscopic level is what you can see with the naked eye. For the microscopic level we need tools like a microscope.

p. 38-42

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.

p. 38-42

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

p. 38-42

Photosynthesis

• 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

p. 38-42

vacuole

cell wall

cytoplasm

ribosome

cell membrane

chloroplast

Homework for next time:

• Questions 56 until 66
• Complete your video in pairs and upload it to Google classroom.
• Complete the mindmap. 
• Study for the Glossary Quiz.

p. 32-37
