Thirsty Celery Experiment- Science

The girls had a fun time watching the celery veins change colors over night.  This science experiment is an example of absorption.  They learned that the stem of the celery stalk soaks up water through the ground to survive.  When we cut the stalks in half the girls noticed that the colored water was sucked up through little holes in the stalk. The veins in the leaves also turned a color.

 

The data was recorded over a three day period using this data record observation form from ABCteach.

Science Experiment-What makes healthy soil?

                                                                      Project 1:
                               We used shredded carrot, lettuce, plastic bag scraps, and soil

 

Cover the items in soil and put the lid on the plastic container.

Questions: 

What do you think will happen?

  Which items will decompose and which items will remain?

What happens when items decompose?

 

(This photo is taken after a week).

Explain that compost is made when the nutrients from the lettuce and carrot combine with the soil, this is healthy for the earth, but the plastic bag will remain for years.

Have your children make predictions on what will happen after a week. Olive was happy that her predictions turned out to be correct.
