Grow crystals from salt or sugar solution by leaving a saturated solution to evaporate slowly. Observe the crystal shape and size over several days – this introduces concepts of solutions and evaporation in a tangible way.
用盐水或糖水培养晶体，将饱和溶液静置使其缓慢蒸发。在数天内观察晶体的形状和大小——这将具象地引入溶液和蒸发的概念。
Create a home ‘friction investigation’ by sliding objects across different surfaces, measuring the distance they travel. This helps you understand fair testing and variables before the term even starts.
在家进行一次“摩擦力探究”：让物体在不同表面上滑动，测量它们滑行的距离。这有助于你在开学前就理解公平测试和变量的概念。
12. Setting Goals and Mindset for Year 7 Science | 为七年级科学设定目标与心态
Set yourself a simple goal, such as ‘I will learn the names of five new pieces of lab equipment by September’ or ‘I will be able to draw a circuit diagram correctly.’ Small, achievable goals build confidence.
为自己设定一个简单的目标，比如“到九月我要学会五件新实验设备的名称”或“我要能正确画出电路图”。小而可实现的目标能建立信心。
