We learned that DNA stands for deoxyribonucleic acid. DNA is a molecule in the form of a double helix - two spirals twisting around each other. These spirals are the backbone of the DNA, and are made up of sugars and phosphates. The spirals are connected by chemicals known as bases, which stretch between the spirals like the rungs of a ladder. DNA has four types of bases: adenine (A), thymine (T), guanine (G) and cytosine (C). A and T always join together, as do G and C.
We learned that some animal cells have small vacuoles which store food, water, and waste. In plant cells the vacuole is much larger to store large amounts of food made through photosynthesis.
Lesson 3 Weather Forecasts
We learned vocabulary for measuring weather. Then we learned which instruments meteorologists use to create data for surface and upper air reports.
Assignment

The Seahorse -
Gracyn selected the seahorse to color today. She used orange as her primary color and then used other colors to bring shadows to her picture. We examined several types of seahorses and discussed how the male is the one that carries the young in it’s pouch, until they are born to the sea. She also learned that there are several different varieties and they can have very different appearances. We also talked about the snorkel trail that runs under the Blue Heron Bridge.

The Queen Triggerfish -
Gracyn selected the queen triggerfish to color today. She used greens and blues and worked hard to make her rendering match the one in the book. We examined several types of triggerfish and learned they come in many colors, live in the ocean (not in the river) and eat shellfish, using their human-like teeth. She did an excellent job and we enjoyed talking about the fish she sees from her deck.
