Science: Matter Matters!

The first science unit of the the year will focus on matter.

Matter can be found in 3 states:
solid, liquid, and gas.

We learned that all matter has physical properties.

We observed the physical properties of our basketball speed ball!
We posted adjectives that described
shape, size/mass, color, texture, hardness, flavor, and temperature.

(Click on picture to enlarge.)

Next, it was time to investigate a liquid,
grape juice, to be exact!

Mrs. Ranney gathered the following materials:
a jug of grape juice, 22 one-ounce cups, 22 popsicle sticks, and an eye dropper.

We studied the physical properties of the liquid.
For example, we observed that the color was purple,
it took the shape of the container, and it was room temperature.

Mrs. Ranney used the dropper to
give each student a 1 mL taste.
Most of us determined that the flavor was sweet and tasted like grapes.

The cups were filled and moved to the freezer.

What do YOU think happened?

Because the temperature in the freezer was 32˚F, the liquid changed form!
The juice was now a delicious solid!

We observed some physical properties had changed.
For example, the texture was first slippery and smooth,
but quickly changed to rough and crunchy!
The temperature was definitely not room temperature anymore!

Science can be deliciously fun!


Science Extra Credit:

At home, find one liquid or one solid to observe.
Please describe as many physical properties as you can.
Remember: physical properties are anything that can be observed
about an object using your five senses.

(Hint - you can copy and paste the list below to add to your comment!)

  3. Dear Mrs Ranney and class,

    Great post about your science lesson! :P

    I am in 2KM at Leopold Primary School in Victoria, Australia.

    Miss McGeady [our teacher] got out our thermometer as soon as we read your post.

    Was it yum? I wish I could of been there to do it with you! Was it fun?

    Science is fun! :)

    Your new friend,


  4. I am glad to see you in the Blog Challenge10 because your blog is going to be one that we follow. Please visit our blog and look around. There is a lot to find. Please add us to your blogroll and we will add you.

  5. Dear Mrs Ranney and class,

    Hi my name is Jazmin in 2KJ from Leopold Primary School!

    The class that I'm next to is 2KM, and they're friends with Mrs. Yollis's class. They've been friends with her class for a while.

    Some of our science activities were the Mentos and Coke experiment the Sherbet experiment, which was my favourite, and the Oobleck. That was really fun!!

    Can you please tell me some of your students' names?


    From your new blogging buddy,

  6. Dear Mrs. Ranney and class,

    Hi, My name is Olivia, and I am in
    2KJ at Leopold Primary School Victoria, Australia.
    The class I'm in is next to 2KM.

    Your science activity sounds really fun. We also do science in our class. Some of the science activities we have done are making sherbet, a coke and mentos experience and dancing currants.

    In Australia grape juice is not very popular.


  7. @ Mrs Ranney and class,

    What a great post you did Mrs Ranney!

    My name is Brooke, and I am in 2KM at Leopold Primary School in Victoria,Australia.

    Miss McGeady(my teacher)got out our thermometer.
    We had a look at it.

    What was the best thing about it?
    Did it taste good?

    Your new friend,

  8. @Ella and Aidan,
    I see you two have been busy scientists this weekend! You made great observations, and I really like the way you used the physical properties list in your comments! Good for you!

    @Mrs. Cranford,
    I've added your blog to our list of blogs that we follow. We look forward to blogging with you!

    @Sophie, Jazmin, Olivia, and Brooke,
    I was so excited to read your comments. My class is on holiday right now, and I know they will all be so happy to see that they have new blogging buddies in Australia!
    I would love to hear more about your science experiments. Can you tell us, for example, what you did with the Mentos and Coke? What did you observe?
    Your new blogging pal,
    Mrs. Ranney

  9. Emily test,

    I tested Peruvian Olive as my solid and Apple juice as my liquid.

  10. Hello everyone,

    I would like to hear more about your experiments.
    Please give us some more details.

    Your friend,

  11. Dear Mrs. Ranney,

    Thankyou for a reply to my comment.

    We made some sherbet in science and I thought it was really fun. We mixed 2 tea spoons of citric acid, a small tea spoon of bi-carb soda and then we mixed them all together and it made sherbet. Do you have any other questions about our science?

    From Olivia (in 2KJ) :-)

  12. Dear Mrs Ranney and class,

    It's me Jazmin again!! :-D

    In my last comment I didn't tell you about our Mentos and coke experiment.

    Well, our student teacher (Miss Brasier) dropped the Mentos into the coke. Since the Mentos had tiny holes in them that you couldn't see, when the mentos got to the bottom of the Coke bottle they started to come out of the bottle of coke! :-) :-D

    When we made sherbet. The ingredients were citric acid, icing sugar and bi carb soda.

    The equipment we needed was a bowl and a spoon to stir the mixture.

    The last experiment so far was Oobleck. Now this was a really fun one!!

    How to make oobleck: First you need a bowl and some water, but don't put too much water in the bowl. Pour some of the water into the bowl. After that get some corn flour. Then when you've done that, gently stir with your spoon. After it's dried and it's a bit of a solid and still a bit soggy, you can play with it with your hands or a spoon!!

    From Jazmin,
    in 2KJ! :-) :-D

  13. Dear Mrs. Ranney,

    I didn't freeze a drink. Instead I used yogurt. The yogurt was frozen. It was so cold on my teeth. It was still really yummy even though it was super duper cold. The yogurt was white, kind of sweet, and hard. Its texture was smooth.

    Your Student,

  18. @Justin,
    I was very impressed with your scientific comment! Can you explain why the frozen juice was in a cylinder shape instead of the rectangle shape that it was in when it was liquid in a juice box?
    Great job!
    Have a nice weekend.
    Mrs. Ranney

  19. Dear Mrs.Ranney,

    I remember when we worked on matter, but we didn't get to make popsicles. Are they going to watch the ice melt? I hope they have fun with things like alpha smarts.


  20. Hi Liam,
    It is great to hear from you. I hope that you are enjoying fourth grade and that you will come back and comment often!
    My class will do many activities that you did last year and some new ones too!
    Mrs. Ranney

  21. Dear Mrs. Ranney,

    I tested a large marshmallow.

    COLOR: white
    SHAPE: cylinder
    SIZE/MASS: small/light
    TEXTURE: smooth
    TEMPERATURE:room temperature
    HARDNESS: squishy
    FLAVOR: sweet

    Then I heated it in the microwave to see if it melt/turn into a liquid. It puffed up but was only liquid on the inside.

    COLOR: white
    SHAPE: sphere
    SIZE/MASS: big/light
    TEXTURE: smooth
    HARDNESS: mushy
    FLAVOR: sweet

    Your Student,

  22. @Leah,
    What an interesting experiment you performed! Using a marshmallow was a great idea. Did you know that by heating it in the microwave, you caused a chemical change? We'll be learning more about that next week when we continue our matter lessons!
    I don't think that I ever commented back to you! I love the fact that you chose a non - food item for your solid. You described it very well.
    How about choosing a liquid to describe as well?

    Keep the great work!
    Mrs. Ranney

  23. Dear Mrs. Ranney, :)

    Your new student,

  24. Dear Mrs.Ranney,

    I tried freezing milk. When it was all frozen, it looked very,very hard. When I was eating the milk, it was very cold. The color was white and the shape was the shape of its jug. The size of the milk was small, the texture was smooth, the temperature was cold, the hardness was hard, and the flavor was yummy.

    Your Student,

  25. Dear Mrs.Ranney,
    Guess what? I tried freezing grapes. The flavor was juicy. The color was purple. The shape was an oval.The size was small. The texture was wet. The temperature was cold. Also, the hardness was soft. I have some questions for you. What is your favorite thing to freeze? I have one more question. What is your favorite food?

  26. Philip's and Nate's Science


    SIZE/MASS:small light
    TEMPERATURE: Room temperature

    Science is great!

  27. Dear Mrs.Ranney,
    I tried freezing chocolate. The flavor was delicious! The color was brown. The shape was a little triangle. The size/mass was small. The texture was dry. The temperature was cold. The hardness was hard. I really like chocolate that's why I tried freezing chocolate. My mom loves chocolate a lot too!

    Your Student,

  28. Dear Class,

    I tested our pumpkin bread that we made!
