Identifying Plant Structures & Functions

We did a lesson on plant structures and functions a couple of years ago, when the twins were 4 1/2, so I thought we would repeat it now they're older (to see how much they remember/have improved!) and for Z's sake as a new lesson as she's recently turned 4. 😙

As before, we visited the Botanical Gardens. In the morning before we went, we read through the most relevant pages from the Roots, Stems, Leaves and Flowers book from the Fundamental Science Collection we have.

While at the gardens, we discussed the different kinds of plants and commented on how the same structure (e.g. the flower) could look so different on different plants. Did they all have roots and stems? Including trees? Could they find them? We stopped at a couple of points around the gardens so the girls could have a go at drawing some plants. They've not done much drawing from life so this was good practise! Z wanted to do one at first, but then she preferred just running around so I didn't force it. 😊 I modelled how to do a quick sketch first and then adding more detail afterwards.

This tree was outside, so after they identified the different structures I asked them what they thought about its trunk. Why was it twisted? Did it grow like that naturally or did someone make it grow like that? How? F said maybe they kept twisting the trunk as it grew. I'm not sure of the answer myself but that seems like it could make sense?! Maybe it's two different trees being twisted together as they grew? Even if we don't know the answer, thinking about it is still a useful exercise. 😁

We also took photos of the plants they were sketching. At home, they watched how I inserted a picture into a Word file and arranged it on the page. Then they had a go with the other photos we took. As well as inserting images, we paid special attention to cropping, resizing, moving them and using zoom to be able to see more clearly what we were doing. I printed the pictures out and they used them as reference to colour in their sketches with coloured pencils.

I was going to get them to label their drawings, but decided against it as felt it would be labouring the point... They already showed they understood by doing it verbally at the gardens, so what was the use in creating extra work as "evidence"?! 😏

On another day, we watched this video clip from the BBC: Ivy's Plant Workshop - Parts of a Plant.

The twins completed the following worksheet, with the guidance that the bottom of the flowering plant should be at the bottom of the table and the top should be at the top... They could either draw four separate diagrams or have a go at joining them to make one tall diagram spanning the table! We talked about the four structures (roots, stem, leaves, flowers) and their multiple jobs, and I wrote some keywords (mainly as spelling help!) on the whiteboard. If they needed more help, they could look in one of the Science books they have which I'd put in the book box for this half term.

When they were done, I asked them to draw and label a tree with the same four labels.

Meanwhile, Z did the activity from our previous post, i.e. drawing a picture of a flower from scratch and me guiding her with adding labels. MashAllah the twins were able to work pretty independently so I was able to give Z enough attention!
