1. February 22, 2013Q-2 Pg. Daily Goal: We will be able to describe the life cycle of a plant. Homework: Have a fantastic weekend! Science Starter: 1.What are 3 things that all living things need? 2.Are plants living or non-living? Support your answer with at least 2 reasons. 3.Where do plants come from? 4.What are 2 things that you already know about plants?

2. February 25, 2013Q-2 Pg. Daily Goal: We will finish learning about plants and will apply our knowledge of plant structures and survival mechanisms by completing our packet. (To be handed out in class) Homework: Finish your plant packet by Thursday. Science Starter: 1.What two things does the stem do? 2.Why do plants have leaves? 3.How and where do plants get energy?

4. Today’s objective By the end of today you understand the changes that plants go through in their lifetime

5. Parts of a plant Roots: The roots help to support the plant and also get water and nutrients from the soil

6. Roots help plants to take up water from the soil (ground). Roots

7. Table Group Point! Roots grow in what soil horizon? What is another name for this horizon? Horizon A Top Soil

8. Parts of a plant Stem: The stem gives the plant support and help to move the water and nutrients from the roots to the leaves

9. Parts of a plant Leaves: The leaves help the plant to make its own food by photosynthesis

10. Table Group Point! Plants make their own food through photosynthesis. This supports which requirement of all living things? Living things can use nutrients to make energy.

11. Plants make their food in the leaves through a process called photosynthesis.Plants make their food in the leaves through a process called photosynthesis. Photosynthesis – when plants use light, water, and carbon dioxide to create foodPhotosynthesis – when plants use light, water, and carbon dioxide to create food Carbon dioxide (C0 ) + water (H 0) + sunlight = food (sugar) + oxygen. Plants inhale carbon dioxide and exhale oxygen. Leaves PHOTOSYNTHESIS 22

12. Table Group Point! Plants inhale carbon dioxide and produce oxygen. How does that compare to what humans inhale and exhale?

13. Stem - the tube that carries food from the leaves to other parts of the plant. This also carries water from the roots to the leaves. Stem

14. Apply your knowledge! Compare this picture to a plant. Which part of the picture would be the leaves? Which part would be the stem?

15. What is this? A flower? Which part is the flower?

16. Flowers typically have nectar inside. Flowers Flowers - are the parts of a flowering plant where fruits which contain seeds are formed. Seeds help the plant to reproduce.

17. Parts of a Flowers Stamen Sepals Pistil Petals

18. FLOWERS PETALS Petals - are the colorful and leaf-like and are usually around the outside of the flower. They are sweet smelling to attract the insects and birds.

19. FLOWERS STAMEN Stamen - the male part of the plant that holds pollen

20. FLOWERS Anther – the tip of the stamen produces pollen and contains plant sperm. Anther

21. Flowers If the pollen goes into the pistil, the plant will REPRODUCE and fruits and seeds will form. PISTIL

22. FLOWERS Ovary – the bottom of the pistil; it contains the egg and grows into the plant’s fruit or vegetable after fertilization Ovary

23. FLOWERS Sepal - the green part that protects the flower bud before it opens. SEPALS

24. Time for a Diagram Label: Sepal Pistil Stamen Petal Flower Stem Leaves

25. Now we know how one flower is formed, but how do we get a whole garden full of flowers?

26. Table Group Point! Just like plants and animals, flowers have to be able to reproduce. What requirement of living things supports this? Living things have to be able to have a population that adapts. Population means more than one.

27. Pollination - is the transfer of pollen from the stamens to the pistil.

28. What are some ways that pollen might be transferred?

29. So that’s how plants are pollinated, and pollination creates seeds. Seeds turn into flowers, and there are flowers all over a garden. How do seeds end up in different places?

30. Seed dispersal occurs with animals, water, and wind and explosive mechanisms. Animals Explosive mechanism

31. Water Wind

32. Table Group Point! What process that helps the rock cycle could also be responsible for transferring seeds and pollen?

33. life cycle of a flowering plant

34. A seed will germinate, or begin to grown when temperature, moisture, and other conditions are right A sprouted seed is called a seedling. At first, the young plant gets its energy from the food stored in the seed. After it grow a few leaves, the young plant begins making its own food by photosynthesis

35. Germination is when the seed has the right condition to grow Plant life cycles GERMINATION

36. A fruit contains and protects seed. The fruit ripens, the seeds are released, AND THE CYCLE BEGINS AGAIN When the plant grows large enough, it produces flowers. Flowers are reproductive structures. After the flower is pollinated, it develops into a fruit.
