Grade 1 students planted many different plants in groups. Before each class, teachers would ask students to observe the changes of the plants carefully and make a record. To get to know more about the usage of plants, kids went to the market to do a survey. They were very surprised to see many products are made of plants; They also did an experiment to get the chlorophyl from the leaves.

Rigging and fitting my Mast and Sails; for I finish'd them very compleat, making a small Stay, and a Sail, or Foresail to it, to assist, if we should turn to Windward; and which was more than all, I fix'd a Rudder to the Stern of her, to steer with; and though I was but a bungling Shipwright, yet as I knew the Usefulness, and even Necessity of such a Thing, I apply'd my self with so much Pains to do it, that at last I brought it to pass; though considering the many dull Contrivances I had for it that sail'd, I think it cost me almost as much Labour as making the Boat.

此外，我还配上小小的桅索以帮助支撑桅杆。我在船头还做了个前帆，以便逆风时行船。尤其重要的是，我在船尾还装了一个舵，这样转换方向时就能驾御自如了。我造船的技术当然不能算高明，然而知道这些东西非常有用，而且是必不可少的，也就只好不辞辛劳，尽力去做了。在制造过程中，我当然几经试验和失败。如果把这些都计算在内，所花费的时间和力气，和造这条船本身相差无几。
