Science

Response to Environment

Students conducted an experiment. They were given a cold meal worm. As the worm began to warm it it became more active. Students enjoyed watching the worm wiggle to and fro. They wanted to take them home as pets. The worms no happily reside in the preschool garden!

 

Science Experiment: Push and Pull

Students needed to use a pencil, paper clip, washer, and string to move the washer from one position to another.

Balance of Nature

Students learned the affects of overpopulation by taking on the roles of predator and prey. Some students were rabbits while others were wolves. As the students tagged their classmates they then became predators. Soon the food supply had vanished. The roles then were reversed by students taking on the role of hawks and others snakes. Again the same result of the food supply disappeared.

Adaptation

Students used a variety of tools to represent the different types of beaks of the Honey Creeper bird. One bear was long and narrow to drink the nectar from flowers. Another beak was strong to pick up larger items. And the last beak was wide to scoop up seeds or insects.

 

Exploring Our Environment

Students toured the school grounds looking for living and nonliving things. They noted all the things they could find in their science spiral notebooks. As you can see there were lovely plants abound. Science class room 3-19 chose a light post as their nonliving item while 3-18 chose the playground equipment.

 

A Third Grade student shares her Science experiment with the class. The students have been studying plants, and discussed how the stem carries nutrients to the leaves. The student's experiment demonstrates this hypothesis, and supports it with evidence.

 

 

Science :Freezing Vapor

Most people did not enjoy the subzero weather we had in February, but our science class had a ball or maybe I should say bubble. We were studying about weather and changing temperatures. The students were excited to find that the bubbles froze almost instantly. This can only be done in extremely cold weather. As the bubble was freezing the students could see the physical change happen before their eyes.

 

Science Olympiad

 

The science Olympiad will be held in late spring ; usually the week before the closing of school. There are ten events that utilize the skills the children have learned during the year. One of the favorite event is the egg drop. The children will pack a raw egg in a container that measures no larger that 5" X 5". The egg will be dropped out of a second story window. All eggs that survive will score a point for the team. The children will work in teams which is a mixture of both third grade classes. Parents are welcome to come to view the events.


McGraw - Hill Science Book

The book is divided into five units (12 chapters). Unit A and B are Life Science; dealing with plants , animals, habitats, and ecosystems. Unit C and D are Earth Science; dealing with resources, land shapes, weather, and space. Unit E and F are Physical Science; dealing with motion, machines, matter, and energy.

The new series is very appealing and challenging. The vocabulary in the text and the support activities are comprehensive and provide an interesting and valuable learning experience.

Painted Lady Butterfly

The class received the larva in a container with food for them to feed on. There were four caterpillars (larva) which arrived in our classroom shortly before Easter break. Since our classroom has a cooler temperature than most our butterflies were the last ones to develop. When they were in the Chrysalis (pupa) stage they did not look very healthy, just hanging on from day to day. We were actually afraid they were not going to develop as we had such cold weather for awhile. The adult butterflies emerged one by one over a three day period. We let them go in the preschool garden where all the lovely flowers will offer a sweet menu.

 

 Science experiment

Many of the classrooms watched the life cycle of the painted Lady Butterfly. The classes received the butterflies in the larva stage Each class built a flight cage . Once the larva developed into the pupa stage , they were transferred into the flight cage. The butterflies were observed and then turned loose in Mary Park or the preschool garden. The following is a web site from the Field Museum and will enhance the children's learning experience.
