Will it Freeze? Experiment

As part of our Frozen-themed unit we did an experiment to see how different liquids freeze differently.  Our question was “Do all liquids freeze the same?”  States of matter are one of the girls’ favorite science topics lately so this experiment was right up their ally.  I loved that it was such a quick and easy experiment that they found interesting.

First we gathered a bunch of different liquids…

Need ideas?  Here’s what all we used:

  • Water
  • Orange Juice
  • Olive oil
  • Sprite
  • Tomato Juice
  • Corn syrup
  • Shampoo
  • Ketchup
  • Chocolate syrup
  • Windex
  • Vinegar
  • Dish soap
  • Milk
  • Hydrogen Peroxide
  • Wine
  • Apple Juice

I made these worksheets for them to use as we went through the experiment.  I thought it was interesting that the girls each had a different hypothesis–one saying they will all freeze the same and the other saying that they will freeze at different times.  The ice cube tray diagram allowed us to keep track of which liquids were in which spot.

We then placed our ice cube tray into the freezer.  Then at our set intervals we would take out the tray and record our observations.  I just had them make an F in each square that was frozen when we checked.  After doing the experiment I realized it would be better if we had checked after 10 minutes, 1 hour, and then 4 hours so I changed the worksheets to reflect that.

The girls were able to come to the conclusion that different liquids freeze at different rates.  We were also able to introduce the idea of viscosity since they were able to see how it affects the rate of freezing as those with a high viscosity froze more rapidly than those with a low viscosity.

 

Pumpkins Math and Science

So Halloween may have passed but I still wanted to share our pumpkin activities, especially since they can still work for Thanksgiving.  And to avoid one monster long post about pumpkins so I divided it up so here are our math and science activities we’ve been doing lately.

Pumpkin Craft–Life Cycle and Parts All Rolled Into One

I combined about five different pumpkin crafts that I liked into one super sciency pumpkin.  First we used three paper plates to create the pumpkin body–one of the base, one for the back pocket, and one of the frame.

Pumpkin Science Craft

We painted the pumpkins with pumpkin-scented paint–just adding pumpkin spice to our orange paint.  We also used a cork for our stem.

On the framed side, we showed the different parts of the pumpkin.  We used real seeds and then pipe cleaners (or you could use orange yarn) for the fibers inside.  While creating it, the girls also cut and pasted the labels for the different parts.

We then added our life cycle vine to the pumpkin.  We used the circle labels for the different stages from printables.atoz

After attaching them to the yarn, we tied it to our pumpkin stem.  They can also get tucked into the pocket on the back side.

Pumpkin Worksheets

Before making our pumpkins, we completed the following worksheets to help learn about the pumpkin life cycle and the different parts of a pumpkin.

Pumpkin Investigation

There are TONS of different pumpkin investigation worksheets out there where kids answer questions about their pumpkin.  This one, from Fun For First, was my personal favorite and the one we chose to use.  It was the most thorough and touched on the topics I wanted the girls to explore.

Number Lines

In math our current chapter is on number order (we use the Singpore Math Kindergarten Curriculum) so I had us make these adorable pumpkin number lines.  While you can use a pumpkin template and then stickers or handwritten numbers, I just used my cricut to cut the pumpkins and numbers.  Then the girls glued them all together.  Finally they strung them on ribbon, which was great practice since we recently started learning to stitch.

And yes, I have realized that my little one did the seven backwards. :)

Number Cards and Playdough

To review our number shapes (and hopefully help with our handwriting) we used these fall-themed number cards from Life Over C’s.

And then for the playdough we used clay made from pumpkin (recipe courtesy of Fun at Home with Kids).  All you need is canned pumpkin, corn starch, and pumpkin spice.  Mix it together until it is the consistency and smell you would like.  In addition to using this with our number cards, it also made a great sensory activity for the girls to play with while I did some one on one work with each.

Different Kinds of Graphs

Since the girls were so into their graphs, I decided to have us just go with it and explore graphs even more.

Our Pizza Graph Display

Our Pizza Graph Display

My goal was to expose the girls to different kinds of graphs since they were interested and to help them see that in math you can say the same thing in many different ways.

As I mentioned before, we graphed what type of pizza our family and friends like to eat.

We then turned that pictagraph into one using slices of pizza to show how many people prefer which kinds.

To help you create your own pizza graph, here are the images I used:

pepperoni pizza
cheese pizza
supreme pizza
Veggie pizza
pizza-boxes
No pizza

 

Following that we also colored in a bar graph similar to the pictagraph with pizza slices.  The girls were able to see that each graph made the same shape and gave the same basic information even though they looked a little different.

Of course we had to make pie graph when talking about pizza.  I cut large pizza images into slices and we assembled the slices to make a pizza pie graph showing the different preferences with pizza slices.  To make the slices all fit together, I actually used powerpoint to “slice” the different kinds of pizza into the same size slices (We surveyed 28 people so each pizza–cheese, pepperoni, supreme, etc–was divided into 28 equal sections.)

We didn’t do quite as much with the graph we made about what people loved as a baby.

We translated our big graph with people’s pictures into a smaller pictagraph using heart shapes.  I tried to get the girls to make their graph horizontally but they were not going for that.  I did make sheets of hearts, both blank to be colored (like we used) as well as hearts of various colors to use.

I probably wouldn’t have introduced so much graphing so early but since the girls were excited, I was happy to follow their passions.  And I think the idea that the same idea can be expressed in different ways is a great take away that will help them as they move forward in math.

 

 

 

Graphing Fun

Who knew graphing could be so much fun?  Once we started it was hard to get the girls to stop!

The graph that started it all...

The graph that started it all…

Our math program had the girls graph the hair color of family members (we are using Saxon Math kindergarten this year which has worked well since it has limited writing but big concepts).  When we finished Mia asked if we could graph people’s pizza.  I don’t know where the idea came from but it started us on quite a graphing kick.

Our first question was “What is your favorite pizza?”  The girls came up with the choices: cheese, pepperoni, meat & vegetables (Supreme), vegetarian, every pizza (Mia’s pick), and no pizza.

To make our graphs we used the profile pictures from our family magnets and sheets of paper taped together (yes, posterboard would work but I’m trying to be more frugal).

Then the girls Skyped with family and friends and asked them their question to graph their responses.

After working on our pizza pictagraph, Zoe wanted to come up with her own question.  Since she loves her lovey, she asked “What was your favorite comfort item when you were a baby?”  Her choices were: lovey, blanket, teddy bear, stuffed animal, doll, or nothing.

What I love about this is that the kiddos were making up the questions and then investigating and reporting the results.  They were practicing so many skills!  It was also a great way to connect with family and friends and include them in our learning.

Weather Mapping

Lately we’ve been talking about how different places have different weather (the girls have been very disappointed it’s not snowing here) so I decided to have us map out the weather.

I wanted to keep the map simple, just the general states, so I used this one from nationalatlas.gov (a great site).

Then I used our weather cards to make these stickers.  We have some sticker paper for the printer but we’ve also just used full size labels in the past.

weather stickers

We put out a call on Facebook asking our friends to share photos of what it looked like outside.  With each picture, we added a sticker to our map.  After just a few stickers the girls started noticing patterns with the weather and understanding how the weather was different everywhere.  This is still a work in progress, but thank you so much to all our friends who helped us!
