class a glass jar with a hard-boiled egg without the shell inside. Turn the jar upside down and ask students for solutions on how to remove the egg without breaking it. Holding upturned jar over a sink or large container, pour boiling water over the jar. This causes the air inside the jar to heat and expand, thus causing pressure pushing the egg out. Ask students how we get the egg back into the jar? Teacher places the egg in the mouth of the jar ensuring there are no gaps. Place the jar into a dish of boiling water. The air inside jar heats up. In order for the expanded air to escape is pulls (sucks) the egg into the bottle. Students to complete a written scientific procedure for this investigation in their SciTech journals. Lesson 4-5 explore (research) – Syllabus Teaching, learning and assessment Resources outcomes ST3-4WS What are a solids, liquids and gases?
