Hydroponics Station

Our classroom is the new home to a hydroponics station. Thanks to parent Mr. Ray for donating the supplies and being a wonderful resource of knowledge as we start this process in our classroom.

Hydroponics is the process of growing plants in water (hence the "hydro" in the name) instead of in dirt. Our station is a plastic tub with holes in the lid which house four plastic cups. This cups will house the plants and the lava rocks that will support them while the roots dip into the water and nutrients int he bottom tub.

We are growing lettuce plants and just "planted" the seed in rockwool two days ago. Germination began already and we are starting to get seedlings! We can transplant them into the plastic cups in a few more days once the roots get longer.

Density of Water Exploration by Abby

1/4/2017

Today we did a lab to explore and review density in order to apply it to something called planetary differentiation. The lab has students measuring and then calculating the density of objects and predicting their behavior in water with a goal to try and determine the density of water. During the lab Abby H. had a question: Can I figure out the density of water?

What a REALLY GREAT question!

She explored and figured out a way to figure it out through measurements and calculations. Feel free to check in with Abby to hear her method and what her result was! Excellent scientific thinking!

We're beginning to look at motion and forces and today we were outside for a lab. We taking footage for an action movie....totally acted by sloths (so no speeding around!!). Here are some pictures of our classes outside, using scooters to set up different scenes so we can observe motion from different reference points and learn what relative motion is all about.
