Science: Lesson 8

Get Ready:

• Macbook
• Kwizl

Plan for today: 

1. Glossary quiz (first 10 minutes of class and counts 1x)
2. Biological drawing. (Working in the lab to draw plant cell with a microscope.)
3. Review. (We will be going through the chapter to check you are prepared for next week.)

Glossary Quiz: 

1. Your Macbook (go to Kwizl).
2. Check all others programs are closed (🍏 & Force).
3. Maximum brightness (F2).
4. Maximum sounds (F12).
5. Waite for your teacher. 

Biological drawing Rules: 

1. No sketching/coloring/shading: only outlines!

2. Only draw what your see.

3. All labels to the right hand side & lines are drawn with a ruler.

4. Top left 3 lines (name, class & date)

5. Top right 2 lines ( title & magnification)

6. Everything with pencil, no pens

LSN 1-1.1: Observing  

• I know what observing is
• I know what tools can be used to observe
• I know what a substance/matter is
• I know what a property of a substance is and can describe properties of a given substance

p. 6-9

LSN 2-1.2:  Working in the lab 

• I can convert between different units in the metric system
• I know the names of the most common lab materials and what
• they are used for
• I know the lab safety rules and safety symbols
• I know where to find the different safety materials in the lab

p. 10-17

LSN 3&4-1.3:  Density 

• I can explain what density is
• I know how the particles look in a low density substance and a high density substance
• I know how to calculate the density using a table if the mass and volume are given
• I know what the unit is for density

p. 18-23

LSN 5-1.4:  Hearing Sound 

• I can explain what sound is and how it travels
• I know what frequency is and how changing the frequency affects the pitch of a sound
• I can draw a sound wave of a high frequency or a low frequency sound
• I know what amplitude is and how it affects the loudness of a sound
• I can draw a sound wave of a quiet sound and a loud sound

p. 24-31

LSN 6-1.5:  Light and Colour 

• I can explain what a light wave is and how it travels
• I know what all the colors of the visible spectrum are, in order from lowest to highest frequency
• I know that white light is a combination of all colors in the visible spectrum
• I know what colors of light are reflected or absorbed based on an object’s color
• I know that white objects reflect all light and black objects absorb all light
• • *VWO ONLY - I know what color an object will appear when a
• colored light shines on it

p. 32-37

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. 37-43

Homework for next time:

• Study the Quizlets
• Study your notes
• Study the lessonups
• Review the hw assignments
• Review the textbook

There is a GEARBOX SCIENCE every Monday afternoon!!

p. 32-37

Answers hw exercises:

51. An atom is the smallest particle of a substance that still has the characteristics and 

properties of the substance. 

52. Molecules are formed when atoms are bonded together to form a different 

substance; for instance, hydrogen and oxygen atoms bond together to form water, 

H2O.

53. In the molecule water, H2O, there are 3 atoms: 2 H-atoms (hydrogen) and 1 O-atom 

(oxygen).

54. In photosynthesis you need energy from sunlight.

Answers hw exercises:

Cytoplasm

Nucleus

Cell Wall

Answers hw exercises:

62. a. Gives the cell strength and shape ⇔ 3. cell wall

b. The part that holds the DNA ⇔ 1. nucleus

c. Photosynthesis happens here ⇔ 2. chloroplasts

d. This layer decides what moves in and out of the cell ⇔ 4. cell membrane

63. a. carbon dioxide + water => glucose + oxygen

 b. CO2 + H2O => C6H12O6 + O2

64. Photosynthesis cannot happen in the roots of plants because the roots are under 

round in the dark. And photosynthesis needs sunlight.

65. Water is needed for photosynthesis. Without water photosynthesis cannot happen.

66. Atoms are the smallest particles, so they cannot be reshaped. Atoms bonded 

together form molecules, and you can combine atoms in hundreds of different ways

to form molecules. So, it is true.
