Why not use the above photographs that I took this morning as inspiration for your writing. You can pause the slideshow if you want to have a closer look. Here are some nouns that are taken from the pictures:
horse, gate, field, tree, branch, bud, hawthorn, sheep, fence, primrose, daffodil, moss, ivy, cow, calves.
Write some sentences about each photograph and add some adjectives to the nouns I have listed above. See if you can stretch those sentences even further. You will remember doing some of this with me in our groups if you are a 4th class student, but anyone can try it!
The white horse stood by the gate.
The white horse stood tall by the rusty gate.
