Four Leaf Clover

Look what he found! What an observant scientist. According to my research:

  • There are approximately 10,000 three-leaf clovers for every four-leaf clover.
  • There are no clover plants that naturally produce four leaves, which is why four-leaf clovers are so rare.
  • The leaves of four-leaf clovers are said to stand for faith, hope, love, and luck.

Quarantine

Mrs. Partridge and I are taking turns feeding the lab animals. I know they miss all the little faces they usually see each day!

The ladybug larvae have really grown! They will go through metamorphosis (egg, larva, pupa, adult). Yes, that’s a baby ladybug!

I brought the millipedes home. Billy and Jilly are doing well!

Two of my second graders are observing and documenting the metamorphosis of our caterpillars. Look at the difference between Friday and Monday. They certainly are very hungry caterpillars!

Snake Skins

My students gift me with snake skins that they find near their homes. I laminated several more of them this week. It is interesting to compare the differences between them. The longest one is over six feet!

Visiting Turtle

Second graders hustled inside to tell me that they had seen a turtle near the pond behind the Lower School. It is the time of year that we catch them laying eggs. We had a great discussion about the dangers of picking up or approaching snapping turtles.

Density Towers

Making density towers is a fun way to demonstrate that liquids have density too! Kindergarten scientists used funnels to pour corn syrup, colored water, and vegetable oil into “baby soda bottles“. The liquids stacked on top of each other because they have different densities. Then we dropped a penny, Lego, corn kernel, and bead into the liquids and their densities determined the liquid in which each floated.

How can you make an egg float? Change the density of the liquid by adding salt.

Will a paper towel tube sink or float? Click here to watch a video about Sesame Street characters making their hypotheses. At first, the tube floated, but then it sank. Why?
