K-2 Science & Tech Lab
 
This week in the lab...

we had quite the break-in! 13 classrooms had windows smashed in and things stolen, including the science lab. The science lab was a mess. The cabinets were open and materials were scattered all over the floor. Glass from the broken window covered the area near the door. Unfortunately, Ms. Phillips' school laptop, 15 digital cameras, and some CDs were taken from the science lab. Our tortoise, Stella, was found outside in the drinking fountain by Rita, our Cafeteria Manager. She's okay, thankfully, but it was quite a scare. To top it all off, the incubator was broken, and our eggs did not hatch on Tuesday as planned.

In spite of this tragedy, it was amazing to see the spirit and camaraderie of Casita families as they joined together to clean up the mess.  A huge thank you to our custodian, Ray, and everyone else that helped put the classrooms back in order.

It seems as though these break-ins are occurring fairly frequently. Since Christmas, our school has been broken into 6 times. While the Sheriff's Department is investigating these crimes, I'd like to take this time to urge anyone who sees any activity on campus after dark or on the weekends, to please call the Sheriff's Department and report it.

Even with all the excitement this week, we still managed to squeeze in some solid science learning! Kindergartners went on a mini field trip around campus, and identified different clouds they saw in the sky. It was a WONDERFUL day for cloud observations! We drew pictures of the clouds we saw on our Cloud Log, and labeled them too! We aplayed an interactive game Ms. Phillips made for the StarBoard called "Swat It," where students had to "swat" the correct type of cloud. During technology time, students tried their typing fingers on for size. We visited the Dance Mat Typing website, and learned about home row, and how to properly place our fingers on the keyboard.

First graders learned anemometers! An Anemometer is a tool that scientists use to measure the strength of the wind. Students made their own anemometers to take home! During technology time, students continued to work on their habitat PowerPoints.

Since Turtle Hurdles was such a hit, we decided to play it again this week! To change it up a bit, we played the game twice. The first time, we had more sea turtles than predators. The second time we had more predators than sea turtles. It was interesting to note the difference in how many sea turtles made it back to the beach to lay their eggs during the first game, as opposed to the second game. During technology time, we continued to work on our Interactive Inference Games, which we are creating in PowerPoint.

During STEM Academy, students learned about the "handiness" of robots! We explored different scenarios where having a robot would be beneficial. Then, students worked in teams of 3-4 students, and used their engineering minds to design and create a robot arm of their very own! The arm had to be at least 18" long, and be able to pick up a styrofoam cup from the ground. Also, students were limited on the materials they could use. Materials available included: cardboard, tape, fishing line, yarn, paper clips, brads, binder clips, straws, clothes pins, rubber bands, and wooden popsicle sticks, scissors, and a hole punch.

I told the students that once the incubator is repaired, I will buy some more fertilized chicken eggs for us to incubate. Hopefully we'll have better luck the second time around!

Well, that's what happened this week at 260 Cedar Road. Until next time, stay classy Casita...
 
This week in the lab...

we candled the eggs again, and it looks like there is only one (maybe two) embryos that are still developing. We're going to keep our fingers crossed that we'll have at least one little hatchling on Tuesday! If not, Miss Phillips will order more fertilized eggs, and we'll try it again.

Kindergartners were introduced to a new part of the computer this week...the keyboard! Students began learning about home-row, and tried their luck at locating various letters on the keyboard. Students worked on the first stage of Dance Mat Typing, and Miss Phillips was blown away with how many students were able to pass the entire stage in their first try! She's never seen so many fast kindergartner typers before! Great job, kindergartners! Instead of doing an experiment in science lab this week, Miss Phillips made arrangements for the Helen Woodward Animal Center's AniMobile to visit the kindergartners at Casita! The AniMobile is a 32' learning center on wheels, complete with animals! The children had a blast. Check out the kindergarten page in the Photo Gallery to see pictures of the event!

First graders continued to learn about weather conditions, and appropriate fabrics to wear in each. This week, we did an experiment to find out which fabric was the most water-resistant: cotton, polyester, nylon, or wool. Students placed a piece of each type of fabric over a cup, secured it with a rubber band, and then poured 1/2 cup of water over each fabric. After testing the fabrics, students compared the cups to see which fabric allowed more/less water to seep through. Students learned that the nylon fabric was the most water-resistant, and therefore the best fabric to wear in the rain! Students also learned that while wool can keep you very warm, it is the least water-resistant fabric that we tested, and therefore should not be worn in the rain. During technology time, first graders continued to work on their Animal Adaptations PowerPoint.

Second graders learned about the life cycle of a chicken this week, which was fitting since next week the eggs are supposed to hatch (fingers-crossed!). We learned the following parts of the egg: eggshell, membrane, albumen (egg white), yolk, germinal spot, chalaza, and air sac. Students also dissected an egg to find each part and examine it up close. Then, students watched a video which explained the process of how eggs get from the farm to the grocery store, and all the steps they have to go through! At the end of class, we candled the eggs in the incubator and compared them to the unfertilized eggs we used during the experiment. We noticed that several of the embryos never began to grow, a few began growing but for some reason have stopped developing, and a couple eggs seem to be developing as normal. During technology time, second graders continued to work on their Interactive Inference games.

This week, only the Monday STEM Academy met. Since Miss Phillips was absent last week, we finished building and testing our aluminum boats. Our winning boats from the penny boat competitions were: Rose and Alyssa from the Monday STEM class which held 300 pennies, and Gisele and Briana from the Thursday STEM class, which held 138 pennies. Congratulations to our winners! Since there is no school on Monday due to President's Weekend, I invited the Monday STEM class to help me with a project on Friday after school. Mrs. Gilot, a parent of a STEM student, is creating a scaled model of the solar system on the playground! She asked if the STEM Academy and I could help her, so Friday afterschool we'll be paining the planets. It should be very exciting!

I hope you all have a safe, and fun-filled 4-day weekend. I'm of to San Francisco to visit my sister! She recently moved to S.F. because she got a nursing job at San Francisco General Hospital. I'm so proud of her! While I'm up there, I will be getting a behind-the-scenes tour of the Academy of Science Museum from one of my good childhood friends who works there...I can't wait! I'll be sure to take lots of pictures so I can show the students next week.

Well, that's what is happen
 
This week in the lab...

we candled the chicken eggs! The results were very interesting. We saw developing chicks inside a few of the eggs, and we saw no developing chicks inside other eggs. We also were able to see a "blood ring" inside one egg. A blood ring is a sign that the embryo, or baby chick, has died. This can happen for many reasons: too much trauma to the egg, the incubator temp or humidity levels were too high, or simply because the embryo was sick and was not able to continue growing. Even though it's sad to realize that not all of the eggs are going to hatch, it is very interesting see see all aspects of the chicken life cycle in our very own classroom! We are keeping our fingers crossed that the eggs with growing embryos will continue to develop, and that in less than 2 weeks we will have hatching chicks! Feel free to stop by the science lab before or after school to see the different stages of eggs we have in the incubator. Miss Phillips has kept all eggs in the incubator with the exception of the two eggs that were broken when they were delivered to Casita. This way, we can compare the eggs and the growth of the embryos over the coming weeks!

Kindergartners continued to learn about clouds. They finished their cloud books too! Next week, we will be using these cloud books on our Cloud Hunt. During technology time, kindergartners were introduced to a new program called Dance Mat Typing. This website teaches children the proper way to type using Home Row keys. The children loved it!

First graders learned about different types of weather. Students discussed what clothing items we should wear for each weather condition. Then, students learned about wool, cotton, and nylon, even looked at them under our microscopes. Students learned that wool is the best type of fabric to wear when it's cold, cotton is the best type of fabric to wear when it's hot, and nylon is the best type of fabric to wear when it's raining! Since Miss Phillips was sick on Wednesday, our technology day, students practiced their typing skills on Dance Mat Typing instead of continuing to work on their PowerPoint projects. 

For second grade science, Miss Phillips invited a few of her friends from the Helen Woodward Animal Center to come to Casita with their 32' AniMobile! They even brought three animal friends with them: Gordo, the Argentine frog (pacman frog), Andy, the Cavalier King Charles Spaniel, and a HUGE skink! The students loved learning about these animal, and even touching them! During technology time, students continued to work on their interactive powerpoint games.

STEM Academy was given the challenge of designing 2 boats out of foil. The boats had to be completely different. Then, students tested both boats in a bucket of water to see which could hold more pennies without sinking. Students took this information, and used it to design a third boat to enter into the class competition. Our winning boat was created by Gisele and Briana, which held 138 pennies

Well, that's what happene
 
This week in the lab...

was a very exciting week! Our chicken eggs have arrived! Miss Phillips ordered 12 fertilized chicken eggs from a farmer in Florida, and they came in the mail! Unfortunately, since they came a week earlier than Miss Phillips had anticipated, she had to wait about 4 days before placing them in the incubator. It takes chicken eggs 21 days to hatch, and when Miss Phillips calculated the hatch date from the day she received the eggs, they were set to hatch the Friday of President's Weekend! That would mean that the chicks would have to stay in the incubator from Friday until Tuesday since we have a 4-day weekend and no one would be at school to take them out of the incubator. Miss Phillips decided to wait a few days before incubating the eggs. Now, the eggs are supposed to hatch Tuesday, February 22nd, the day AFTER we get back from President's Weekend. Miss Phillips is a little nervous about the eggs though, because the did travel a great distance to get to Casita, and after doing some research online she found out that the eggs should be placed in the incubator within 10 days after being laid. Since she does not know when the eggs were laid, keep your fingers crossed that we'll at least have one egg survive this crazy ordeal!


Kindergartners began learning about clouds in science lab this week! Students learned about 4 main types of clouds: cumulus, cirrus, stratus, and nimbus. Students also began creating a cloud book, which shows the four kinds of clouds made from cotton balls. During technology time, students explored various websites we have learned throughout the year.

First graders learned about measuring temperature with a thermometer. Last week, we used traditional thermometers to take the temperature of three difference cups of water. This week, however, we were introduced to digital thermometers, and used them to measure the air temperature at various points around campus. Then, we discussed why the air was cooler in some spots and warmer in other spots, and how shade can play an important role in keeping us cooled off...and shade is free! During technology time, first graders began their next technology project, an Animal Adaptations PowerPoint! Students created their Title Slide, and saved their PowerPoints.

Because it was rainy during the early part of the week, Miss Phillips decided to plan and indoor activity instead of going outdoors and playing Turtle Hurdles again. Miss Phillips showed the students a video created by some Animal Care Specialists at Sea World who focus on the rescue, rehabilitation, and release of sea turtles. The students LOVED IT! Then, in groups of 3, students played a sea turtle board game, similar to the game "Life," in which players simulate the trials and tribulations of a sea turtle's life with the roll of a die. During technology time, students began their next technology project, an Interactive Game! This game will be created in PowerPoint. This week, students created their Title Slide, background, and saved their PowerPoints.


During STEM Academy, students tested their paper bridge designs to see how many pennies their bridges could hold!

Well, that's what happened this week at 260 Cedar Road. Until next time, stay classy Casita...
