Slide 2: Act 1.Photosynthesis questions: doc p.16

WATCH THE VIDEO:PHOTOSYNTHESIS FOR KIDS

• 1. What part of the word photosynthesis tells us that these plants

need sunlight energy for this process?

• 2. Photosynthesis occurs in the stem / leaf / roots of the plant?
• 3. What gas is absorbed by the plant?
• 4. What gas is released by the plant?
• 5. What does the plant absorb through its roots during this process?
• 6. The plant releases a gas during photosynthesis, but what does it

produce (make)? It makes food in the form of G…….. (See photo)

• 7. Remember plants can be a tree, grass, bush, shrub or plant.

Give three examples of food that any plant can produce?

• 8. Thinking Question:

Why is it important for humans and animals that we preserve (keep / protect)our plant life and avoid cutting down trees and destroying vegetation? Think of two reasons.

Slide 3: Activity 2: Animals’ life processes doc p.17

Animals / mammals, unlike plants, cannot produce their own food. They eat plants or

• ther animals to get energy to survive and to fulfill their life processes.

Task:

• 1. Animals need energy to perform these processes. Name the seven life processes.
• 2. You have studied the animal feeding groups in term 1 under Interdependence.

These photos show 4 types of animal feeding groups. List the four groups 1-4 and explain in a brief sentence why they are classified (grouped) as such e.g. no….. is a ……… herbivore as it eats…….

• 3. Find 4 of your own pictures from magazines/ the internet/ own drawings to show

another example of each of these groups. 1 4 3 2

Slide 4: Activity 3: Food Chains doc p.18

Info block 1: Vocabulary: Please copy these key words under the heading above.

producers: plants that produce or make their own food consumers: animals are unable to produce their own food, so they consume (eat) plants and animal energy flow: energy that is passed on from one organism to the next. food chain: the order in which animals eat plants and other animals to get energy There is a feeding relationship between producers and consumers. We call this relationship a food chain.

• Plants are the producers.
• Animals are the consumers

Info block 2: A food chain describes how energy is passed from one organism to the next.

• When we draw a food chain we use an arrow between organisms to show that one eats the other and

that energy is transferred from the one organism to the next.

• A simple food chain is: grass cow human.

Do not get confused. Although the arrow points forward, it does not mean that the grass eats the cow and the cow eats the human – the arrow shows an energy transfer only. You read the food chain backwards. Human eats cow that eats grass.

Slide 5: Activity 4: Food Chains doc p.18

Design your own food chains on an A4 piece of white / coloured paper. See my e.g. alongside. Source /draw basic pics. 1. Have a heading: FOOD CHAINS 2. Label in black fineliner. Arrows in red. 3. Start with a producer (plant).

• 2. The 2nd link has to be a herbivore

as it is a plant eater.

• 3. The 3rd and 4th links are either carnivores
• r omnivores. There does not have to

be a 5th link.

• 4. There is also another example on slide 4.

Act 6 (a) NAME OF ANIMAL ANIMAL FEEDING GROUP FOOD EATEN

• 1. bird
• mnivore

plants and meat

• 2. baboon
• 3. zebra
• 4. locust
• 5. snake
• 6. buck
• 7. lion

:

❑ Act 6 (a) Redraw the table. Decide which feeding group the animals in the busveld below to. List if they eat plants/meat or plants and meat. ❑ Act 6 (b) Draw a bar graph on the lined paper below the table. Each bar shows the no. of animals in each group. (green: herbivores; red: carnivores; yellow: omnivores) Heading: Feeding groups in the busveld ; x-axis: 3 bars: feeding groups; y-axis: no. of animals: count from 0-7: each line is a no. ❑ Have a key showing the 3 colours of your bar graphs.
