Expériences faciles How To Grow An Avocado Tree You can make some pretty tasty dishes with an avocado but did you know that you can grow a tree from it too? It probably won’t produce any fruit, but it is a nice addition to your home plant life. For best chance of success, try this with a pit that has been taken from a very (very) ripe avocado that hasn’t been refrigerated. You may also want to start 2 or 3 at a time in case one fails. Tip: If you have plenty of sunny locations in your home, you could start several of these in the early Fall and have a bunch to sell at your annual summer yard sale or donate to church raffles, team fundraisers, etc. Directions: Another Option: Push pit into a mix of sand and potting soil (pointy side up) with the top half above soil surface. Another Method: Wrap in moist paper towel and place in a ziploc baggy, seal.
Ressources Navigation dans Internet L'enseignant s'assure que les élèves connaissent les bases de la navigation dans Internet : activer un lien, copier et coller du texte du navigateur au logiciel-outil Word. L'enseignant s'assure que les élèves connaissent les fonctions de base du module de traitement de texte. Intention pédagogique Rédiger une fiche explicative illustrée sur une plante médicinale. Ce projet vise également à sensibiliser les élèves aux possibilités que possèdent les plantes de soulager des maux bénins que nous subissons au quotidien. Temps pédagogiques Mise en situation Avant de présenter cette activité aux élèves, planifiez du temps pour cette petite mise en situation, qui soit dit en passant, est très appréciée : 10 minutes avant l’entrée des élèves en classe, faites brûler 4 à 5 gouttes d’huile essentielle de romarin dans un brûle-parfum. Qu’est-ce que ça sent ? Écrivez toutes les réponses des élèves au tableau pour constituer la carte d'exploration. Réinvestissement
The pumpkin project (revisited) I have been getting lots of questions about the pumpkin seeds growing inside the pumpkin. We started the pumpkin project for this year today. I sure hope it is as successful as it was last year. Anyway, my first post may not have made it clear that we only opened up the pumpkin, added a little soil and water, and watched the seeds (which were already inside the pumpkin) grow. The pumpkin we used was intended for making pumpkin pie. We left all the "guts" and seeds as they were (except the few that came out with the lid). Here is last year's plant when it sprouted: You can find pictures of the full grown plant growing outside our window here: And as I mentioned previously, I LOVE to read the book Pumpkin Jack to my students several times while we observe the pumpkin life cycle.
Fun Classroom Activities and Experiments to Interest Children / Kids in Growing Plants Growing a cutting can be fun too. I recommend Fuchsia's or Geraniums as they are easy to grow. Firstly get a cutting by taking a section of non-flowering stem and cut it free with a clean knife from just below a leaf joint. Remove the leaves immediately above the cut. Get hold of a thin sheet of polystyrene and punch some small holes in it. Thread the stems of your cuttings though the holes so the remaining leaves are on the top surface of the polystyrene. Obtain a tray or tub suitable for holding water and fill to virtually the top. Float the polystyrene complete with the cuttings on top of the water, or if the jar is small enough you can balance the cutting within the water using its leaves to suspend it on the neck of the jar, and without the need for polystyrene (as per the right hand image). Change the water every couple of days, and before too long your cuttings will produce a root system.
