The 5th grade scientists might be tired this week because of all the modeling we have been doing as we continue to dive deeper into discovering what matter is and how it affects organisms.

So far, through experimentation we have figured out the following:

How do we know for sure that air and water give the plants matter? Well because we weighed both air and water and we know that anything that takes up space or has mass is MATTER! When we blew air into the balloon and its weight increased, that PROVED it is matter. We also know that when we add water to something, its weight also increases, which once again PROVES it is matter!

But what about light?????????

Light does not take up space, it does not have mass (we shined light onto a scale and the scale stayed at 0.00 grams), so how on earth can it help our plants grow? Stay tuned because we are going to be investigating this idea next week!

Take a look at some of the amazing modeling/thinking the 5th grade scientists have been doing this week.

Modeling air in a syringe:(compressed, expanded, vs open)

Modeling how/where plants get their matter from to grow:

Have a wonderful weekend,
