Transpiration is the loss of water from a plant. Transpiration mainly occurs from the leaves. Water vapour diffuses out of the stomata ( tiny pores mostly found on leaves ). Loss of water from the leaves creates a pull on the water in the xylem cells, drawing water up the plant. This movement of water…
Once a plant has made seeds ( remember pollination and fertilisation? ) they need to be dispersed. Seed dispersal is the scattering of seeds. If seeds just dropped next to the parent plant, they would be competing for nutrients and light, so it’s better if seeds are spread out, allowing them to grow with less…
Magic opening flowers are a brilliant, super simple science investigation using just paper and water. The folded paper flowers open up as the paper absorbs the water. They are a great way to learn about capillary action and transport of water in plants too. You can make these as simple or creative as you like….
We’ve dissected flowers many times before, but this was our first attempt at a 3D flower model. A model is a great hands-on way to learn about the structure and function of plant organs and the importance of pollination. I’ve also made some FREE flower structure revision cards you might like. 3D Flowering Plant Model…
Green plants make sugar for growth by a process called photosynthesis. Photosynthesis is a process where light energy is converted to chemical energy in the form of sugars. Photosynthesis provides the main source of oxygen in the atmosphere and is essential for almost all life on Earth. Photosynthesis made simple Plants use sunlight, water, and…
Plants don’t always seem like the most interesting of topics to study, but there are lots of brilliant, hands-on plant science experiments and activities which are fantastic for learning about different types of flowers, trees and plants and the conditions they need to grow. I also have a free booklet at the bottom of the post containing…
Every now and then we like to try a more ‘traditional’ science experiment and walking water is one I’ve been trying to catch on video for ages. This super simple experiment works quickly and is very impressive. The science behind it, can be a bit tricky for little ones, but you could start by spilling…
