Plant Life Cycles

We are studying the Life Cycle of Plants.

We practiced making a hypothesis, which is a good guess as to what will happen next in our experiment.  

Our question is:  Will a stem grow 
in water or soil? 

This is our Question:

We made a sentence frame for our hypothesis:

My hypothesis is that a stem will/will not grow in soil/water because . . . . . 

First we examined the stems using a magnifying glass.

Next we described the properties of the 
stems and plant pieces.

Then we got our journals out and 
formulated our hypothesis.

My hypothesis is that the plant will grow in water because if you touch the plant, it feels like water is inside the plant.  Inside the plant there is something green that takes in the water.

My hypothesis is the stem will grow in soil 

because it will grow back roots.

My hypothesis is that the stem will not grow in water because water does not have nutrients for the plant to grow.  The plant needs nutrients because the nutrients give food to the plants so it can stay alive.  

My hypothesis is that the plant will grow in water because if you touch the plant, it feels like water is inside the plant.  Inside the plant there is something green that takes in the water.

My hypothesis is that a stem will not grow in water because it does not have roots.  The plants need water, sun, soil and space to grow. 


Last we drew plants and labeled the parts of the plant, making sure our drawing matched what we observed.
