Squeeze a big dollop - about one tablespoon - of toothpaste on top of the egg and gently rub the toothpaste all around with your hands until the egg is completely covered in a thick layer of toothpaste. Fill two glasses halfway with lemon juice and place behind the Juice 1 and Juice 2 sticky notes. Fill two glasses halfway with brown soda and place behind the Soda 1 and Soda 2 sticky notes.Write on sticky notes: Soda 1, Soda 2, Juice 1, and Juice 2.This one will really get them into brushing their teeth once they scientifically prove all the good things that toothpaste can do. These are mostly designed for preschoolers through elementary schoolers, but if you have a younger one, you can check out these 1-year-old learning activities, toddler learning activities and preschool/kindergarten learning activities, some of which also cover STEM subjects. As always, safety counts: wear goggles and coats or aprons if need be (sometimes kids get a kick out of how scientific the protective gear makes them look), and always make sure that the kids are supervised when doing them. These kid-friendly experiments cover magnetism, surface tension, astronomy, chemistry, magnetism - you name it - and in ways that lets kids really see how the forces around us work. So, next time you need a bordeom-busting indoor activity on a rainy day or a DIY project to keep them busy, pull out one of these ideas and get them to start making hypotheses. You probably have most of the materials you need to do these science experiments for kids sitting around in cupboards and drawers. So while a kid who is interested in the subject might have fun with STEM toys and science kits, you don't actually need to go out and buy something special to keep the STEM learning going at home. If we used the list item for the effect, we'd need to set a tabindex property to get the same access.Science, and the scientific method, are just ways of describing what is happening in the world around us. This is a good element to use for interactive items, as it automatically means that our notes become keyboard accessible. Notice that each note is surrounded by a link. As we are using HTML5 for the effect, the basic HTML of our sticky notes is an unordered list with a link containing all the other elements in each list item:
We will be using some common CSS properties that work across all browsers. Older browsers simply get some yellow squares. The effect is built up gradually and works on all up-to-date browsers like Chrome, Safari, Firefox, and Opera.
In this tutorial, you'll learn how to transform an HTML list into a wall of "sticky notes" that look and work like the following:
