Screenshot and copy in your notebook No Scientific Questions Independent Variable (the variable that you change) 1 Can the chocolate melt if we heat it? 2 3 4 Dependent Variable (the variable that you measure) Control Variable (the variable that you kept the same ) The temperature to melt the chocolate bar NO DV The same size of chocolate The same weight of chocolate The same type of chocolate How long the ice cube will melt? NO IV THE TIME NEEDED FOR THE ICE CUBE TO MELT The same size of ice cube The same shape of ice cube Time to do the experiment tool to melt the ice cube Does changing the amount of ice cube will affect how long it will melt? Does the size of candle affect how long it will melt? The amount of ice Time The same size , shape of ice cube, starting time to start the experiment https://forms.gle/igTmFkrP1aHaH7zq9 Screenshot and copy in your notebook No Scientific Questions 1 How does the size of a dog affect how much food it eats? 2 Does the temperature of water affect how quickly it freezes? 3 Does changing the amount of ice cube will affect how long it will melt? Independent Variable (the variable that you change) Dependent Variable (the variable that you measure) Hypothesis (If....then....because...) Screenshot and copy in your notebook Imagine that you design and conduct an experiment based on your hypothesis that adding fertilizer to soil allows more plants to grow. You find that in the soil with fertilizer, more plants grew than in the soil without fertilizer. Sq: IV : DV: CV : Hypothesis : If ....IV ....then ......, because ( find the background research about this before) Screenshot and copy in your notebook Imagine that you design and conduct an experiment based on your hypothesis that adding fertilizer to soil allows more plants to grow. You find that in the soil with fertilizer, more plants grew than in the soil without fertilizer. Sq: Does adding the fertilizer can make the plant grow taller? Does adding the fertilizer can affect the plant growth? The number of leaves or the height of the stem=> 2 DV IV : adding the fertilizer ( with and without fertilizer) DV: 1. number of the plant or bud that sprout 2. the height of the plant CV : the type of the plants, the type of soil and the amount of water, the amount of soil, the age of the plant Screenshot and copy in your notebook Hypothesis : If we add the fertilizer then plant will grow taller or has more number of leaves, because the fertilizer give more nutrient to the soil that can improve the plant’s growth ( find the background research about this before) Screenshot and copy in your notebook Variables : The factors in an experiment that can be changed Screenshot and copy in your notebook Example of variables would be : changing the temperature, the amount of light
