学习目标
objectives
1. The new words: experiment, jar, upside, pour, correct, scientific, method, raincoat, force, pressure, conclude
Listen and sing a song.
What is science? What is science? Can you explain? Please make it easy for my brain. It’s about making observations. Why do onions make me cry? Why do clouds go by? What keeps the birds in the sky? That’s just science.
what will happen. 5. “Observe ” is another way of saying
“watch carefully”.
Let’s do an interesting experiment. First, I _p_u_t _ a jar _o_n___a desk, _f_i_ll_it _w_i_t_h_ water, then _c_o_v_er_the top _w_i_th_ a piece of cardboard. When I _tu_r_n_the jar _u_p_s_id_e_ __d_o_w_n__, can you guess what will happen?
• 1.What’s Danny’s theory? Danny thinks the floor will get wet.
• 2.What’s Jenny’s theory? Jenny thinks the water will stay in the jar.
• 1.Where does Danny think they should do the experiment? He thinks they should do it outside.
10.So what have we discovered? discover为动词,意为“发现”,是指发现或找出某种自然界本 来已存在,但以前未被人类发现或认识的事物。 【辨析】 find,find out,discover,invent (1)find意为“找到,发现”,强调“找”的结果,也可指偶然发 现、碰到,其后可接名词、复合结构或that从句。
9.It is strong enough to hold the water. “It is+形容词+enough to do sth.”意为“做某事是 足够……的”,常用来表述某人或某物的能力或特 征。在此句型中,当不定式的逻辑主语与句子的主 语不相同时,常用for引出不定式的逻辑主语。该句 型可以和too…to…及so…that…句型相互转换。
2.I think the floor will get wet. ◆I think…意为“我认为……”,其后可接that 引导的宾语从句。在使用时,应遵循“否主反 从”的规律,即否定主句,反问从句。 ◆get wet意为“变湿”。get在本句中为系动 词,意为“变得……”,后接形容词作表语。
3.We should do this experiment
• 2.What keeps the water in the jar? The force of the air.
• 3. Is Jenny sure of her theory? How do you know?
Yes, she is. She thinks that Brian can do the experiment over Danny’s head.
Let’s Do It !
In a small group, try the experiment above. Try it with the jar full. Try it again with the jar nearly empty. Write down your observations. Did the experiment work? Did anyone get wet?
It’s about matter—the universe. Why does a car stay on the road? Why is there green all over a toad? Why can’t I carry a heavy load? That’s just science.
outside,Brian. experiment为可数名词,意为“实验”。do experiments/do an experiment意为“做实验”。 【拓展】 experiment作动词,意为“做实验, 进行试验”。
4.You think the water will pour out,Danny. pour out意为“倒出,使流出,涌出”。pour在 本句中表示“涌流”。 【拓展】 pour…into…意为“把……倒 进……”。
(2)find out指“弄清楚,查明”。着重表示通过调查、分析、 思考等得出结果。
(3)discover意为“发现”,指发现已存在但不为人所知的事 物。
(4)invent意为“发明”,指发明原来不存在的东西。
11.What do you conclude,Danny? conclude为动词,意为“断定,推断出”,其后可接由that引导的 宾语从句。 【拓展】conclude from意为“从……推断,从……中得出”。
Try to do the experiment in this lesson yourself.
Task tips: What happore water, wet cardboard, or different kinds and sizes of jars?
2 Put a piece of cardboard over the jar. 5 The jar of water is upside down, but the water stays in the jar. This is because air pressure pushes the cardboard onto the jar. 1 Fill the glass jar with water. 3 Turn the glass jar over quickly. Hold your hand on the cardboard for a few seconds. 4 Remove your hand from underneath the jar. What happens? 6 There is more air outside the jar than inside, so there is more air pressure outside than inside.
5.That’s called the scientific method. ◆be called意为“被叫作”,是被动语态。被动语态 是由“be+及物动词的过去分词”构成,其中be动词 可随句子时态的变化而变化。
◆scientific为形容词,意为“科学的”。scientist为 可数名词,意为“科学家”,science为不可数名词,意 为“自然科学”。
• 4. Why does Danny put on his raincoat? He thinks the water will pour out.
• 5. What does Danny conclude? The air is stronger than he thought.
