Today we did a science experiment. We had clay and straws and three liquids. Out of the straw and clay, we made hydrometers. Hydrometers measure the density of a liquid. First, we had to try out all three hydrometers in water so they were exactly the same. Then we tested them in all three liquids.

We discovered that maple syrup was the most dense and oil was the least dense. Water was in the middle. We had a great time doing our science experiment!

Science Pictures - All About Water


Science has been lots of fun lately! We've been exploring matter (solids, liquids and gases) and water. After making molecule hats and learning the molecule dance, the class began exploring how water acts. We'll continue experimenting with water (look for some fun experiments coming home for homework) and learn about the water cycle. The students have been recording all kinds of observations and conclusions in their science notebooks. Hooray for science!

OOBLECK!
Is it a solid or a liquid?



Jillian is moving!
We'll miss her.
So we had a party.
Good luck, Jillian!

In writing, we talked about topic sentences and how they usually tell the main idea of a paragraph. Then all the other sentences give evidence that supports the main idea. We wrote some paragraphs about places in Ipswich. Some people had a main idea about the YMCA, and other people had a main idea about Crane Beach. We've been working hard on paragraph writing.

Today in math, we learned how to use half-circle protractors. They help you measure angles. First you have to line up the center with the vertex of the angle you are measuring. Then you line up the zero on the protractor with one side of the angle. Then you see where the other side of the angle hits on the protractor and that's how many degrees the angle is.

In science, we've been exploring solids, liquids and gases. Today we had two exciting stations. One station was Mystery Substances. There were four mystery substances and they were peanut butter, baby powder, hand cream and Vaseline. We had to discuss whether we thought they were solids or liquids.








At the second station, we turned a solid into a liquid, then it turned into a gas. We talked about a gas is with that experiment. A gas is something you can sometimes smell, and it expands to fill the space it is in, and it has no definite size and no definite shape.





Miss O'Reilly read a book called 'A Blue so Blue' in reading, and we practiced inferring about a book's theme. Some of the themes we came up with are:
-Never give up.
-Sometimes what you are looking for has been close to you all along.
-Believe in your dreams.
-You don't have to look very far to find your dreams.

Science Experiment Day

Today we had two experiments to see if we could prove that air takes up space. One of the experiments had a cup with a paper towel in it. We turned the cup over and pushed it down into water and the paper towel stayed dry! That's how we know that air is matter because it pushed out the water because it was taking up that space.



In the second experiment, we took a plastic cup and cork. We dunked it into a huge tank of water and watched to see if the cork would float to the top or stay at the bottom of the cup. The cork stayed on the bottom of the cup because air took up space and wouldn't let the water come in.

Today was a super, awesome day!

Division Matters!

Today was an awesome, excellent day! This morning, we did a practice MCAS question with Mrs. Spencer. Then we learned partial quotients in math class! Partial quotients is a way to find the division answer to harder problems.

This afternoon, we made an experiment to find out if air is matter. Matter is something that has weight and takes up space. We used a yardstick and put two balloons on the ends. Once the yardstick was balanced, we stuck a needle in one of the balloons and pulled it out so the balloon started deflating slowly. We proved that air takes up space and has weight because the yardstick started tipping to one side - the side that had the full balloon. So that balloon was heavier and it had weight! We love science in room 3. (We also are working in science groups and made funny names for them. That was a hoot.)

Ask your kid about division and matter!
