Put the centre piece of the nappy into the ice cream container and gently take it apart.

If tubs are in short supply, large zip-lock bags can be used. Adding alkali removes the acid ions and moves the equilibrium to the right; adding acid has the opposite effect. Level years years years. Estimate the final volume of the hydrogel. The hydrogels that are commonly available and are used in this practical activity are sensitive to salt concentration, but do not show much change across the pH range that can be readily investigated in the classroom. Summary Areas of Science. When salt is added, the viscosity immediately reduces and the mixture is easier to stir.

In association with Nuffield Foundation, pampers hydrogels. Investigate pampers hydrogels as polymeric smart pampers hydrogels in this series of activities using nappies and cheap hair gel. In this pair of experiments, students explore the properties of hydrogels used in commonly available products — in this case, disposable nappies and cheap hair gel. The practical work is fun to do, and the pampers hydrogels are sudden and dramatic. To do all the practical work takes about 30 minutes, pampers hydrogels. The hair gel experiment is a good quick introduction to hydrogels, while the nappy experiment is more detailed. If time is available, it is worth considering combining this practical with this experiment exploring hydrogels in the context of plant water storage crystals. This activity can be used to enhance the teaching of ionic and covalent bonding, or hydrogels can be considered as an interesting polymer as well as an example of a smart material. Hydrogels are smart materials because they change shape when there is a change in their environment — in this case it is the change in the concentration of ions. Students need to have some knowledge and understanding of ionic and covalent bonding, pampers hydrogels, reversible reactions, and acids and bases to understand what is happening.
