We will continue working on Living Beings, today with different ways to work with plants in Primary School.
According to the curriculum, the following objectives must be met:
- Observation of a living organism in its natural environment or by recreating this environment in the classroom.
- Characteristics of plants in adaptation to their natural environment.
- Oral Communication of their observations.
Let’s start with the observation of a plant in its natural environment and in the classroom:
1. You can collect different seeds and study them as we made with some helix shaped seeds we found.
2. Once you have collected some seeds, you can find out how a plant comes out from the seed, observing the roots and stems growing. If you grow edible plants, you can also use this activity to introduce sprouts in your diet.
3. You can also clearly see the parts of a plant germinating the seeds in empty CD boxes as they suggest in Two Busy Brunettes web page. Or in a plastic sealed bag on a window. This way it is also easy to draw with a marker the different parts of a plant as it grows.
4. You can also see other ways of growing a plant, not only from seeds. Like for example the growing of a plant from the top of a pineapple.
5. If you want to look closely at the leaves, you can start by collecting different leaves to dry and press as they suggest in Proyecto Azul, and observe them in a ligth table, for example. You can also clearly see the nerves making leaf rubbings on a sheet of paper with crayons as they suggest in No time for flash Cards
We will continue exploring plants finding out what does a plant need to live:
6. Plants need water. Any liquid is valid? Can a plant survive and grow if watered with salted water or milk or juice? We can make a research as they suggest in education.com web page.
7. Plants carry water from the roots to the leaves through the stem, thus transporting nutrients. You can check this with the colored flowers experiment.
8. Plants transpire through their leaves. That means that the water that we have seen that reaches the leaves is lost again through them by evaporation. You can see this with a simple experiment where you place a plastic bag around the leaves as they suggest in The Hmmm…Schooling Mom. Or you can perform a more complex experiment by measuring the exact variation in the mass of a plant due to the water loss, as they suggest in Science Stuff.
9. Plants need light. You can test it by creating a maze in a box and placing a plant in it, as they suggest in Herbarium web page. You will see how the plant grows in the box making its way to find the light at the end of the maze.
10. You can make a Terrarium to observe the growth of a plant and understand the water cycle (evaporation and condensation) that keeps the plant watered inside without any additional water. Or you can even go further and create an entire ecosystem of acuatic and terrestrial plants.
11. Finally, you can see why tree leaves change color in Fall by making a leaf cromatography as they suggest in Almost Unschoolers web page.
