My daughters and I continue to do our science lessons using Apologia Exploring Creation with General Science for our science course this year.

We’ve had a lot of fun doing multiple science experiments already using this book. I love how the suggested science experiments use easy-to-find (if not already on hand) supplies. I also like the hands-on approach the science experiments add to the reading.

You can click here if you are interested in seeing the books Apologia offers. Please keep in mind the science books are written from a creationist point of view.

I’ve talked about a couple of the science experiments we have already completed using Apologia Exploring Creation with General Science.

We did a simple science experiment that answered the question: do molecules move faster in cold or hot water.

Does food coloring mix faster in cold water or hot water?

We also did this simple science experiment when we discussed atoms and density.

Simple Science Experiment

I won’t be sharing every science experiment we do along with our current science lessons (there are over 50 of them!); however, today I am showing another simple science experiment we completed during our reading.

This was a neat experiment to show chemical reactions. The science book gives a detailed explanation of what the chemical reactions were, what substances interacted together, and what new substances were formed. I’m not going to get that detailed, but I will still show you what supplies we used and a general idea of the steps we did to complete this experiment.

Supplies

  • clear, empty plastic 2 liter bottle
  • white, distilled vinegar
  • balloon
  • 2 Tbsp baking soda
  • funnel
  • purple cabbage
  • water
  • small pot
  • stove
  • ladle
  • measuring cups (1 c., 3/4 c., 1/2 c.)
  • safety glasses

Directions

  • Boil 2 cups of water in a small pot on the stove with some cabbage leaves. The water should turn purple. Let it cool for a little bit and remove the cabbage leaves.

purple cabbage base

  • Pour 3/4 c. vinegar into 2 liter bottle.

vinegar in bottle

  • Pour about 1/2 c. of the purple cabbage water into the 2 liter bottle using a funnel.

Pouring base into vinegar

  • Notice the color change. The white vinegar and the purple cabbage water made the vinegar (an acid) red.

  • Pour baking soda into the balloon using a dry funnel.
  • Cover the lip of the 2 liter bottle with the balloon’s opening. Make sure the balloon is securely attached.
  • Move the balloon so the baking soda falls into the mixture in the 2 liter bottle.

  • Watch the chemical reaction occur as the mixture fizzes and the balloon gets bigger.

  • Eventually, the mixture will stop fizzing.

  • Notice how the red mixture has now turned purple when the baking soda (a base) was added.

It’s as simple as that!

I ended up buying an entire head of cabbage for this experiment even though it only required a few leaves. As a result, we had quite a bit of cabbage left over.

Similar to when we did our grand pumpkin experiment, I searched online for a recipe so that I could use the left over cabbage pieces.

Who knew that these science lessons would lead to some cooking lessons as well? We ended up sampling some baked cabbage later that day.

As I had mentioned in a previous post, my daughters and I have been using Apologia Exploring Creation with General Science for our science course this year.

The companion student notebooks (I purchased one for each of my daughters) have been very useful. They have an entire section devoted to scientific lab reports that go along with the course. My daughters are required to complete each of the scientific lab reports when we do the experiments.

Scientific Lab Report 1.2(A2)

My daughters have been getting so much practice following the scientific method lately that they even reminded me of it when I recently declared “Our Grand Pumpkin Experiment”.

We have been able to complete all of the recommended science experiments together so far. I’m hoping we will be able to complete them all, but we will see. There are over 50 within this course!

You can find all of the products Apologia has to offer here.

Below is a science experiment we recently completed during our reading on atomic motion.

Does food coloring mix faster in cold water or hot water? 

We gathered the following materials.

  • 2 quart sized canning jars without lids
  • green food coloring
  • small pot of hot water (heated on stove)
  • cold water
  • hot pad
  • funnel
  • eye protection

Then, we completed the steps listed below.

  • Fill one of the canning jars up to the 400 ml line with cold water.
  • Run the other canning jar under warm to hot water from the faucet. (I did this because I was worried the jar would break with the sudden temperature change of the hot water.)
  • Fill the warm canning jar to the 400 ml line with the hot water. Place on hot pad.
  • Put one drop of the food coloring into each jar at the same time.
  • Watch what happens.

Will the molecules move quicker in the hot water or the cold water?

Does food coloring mix faster in cold water or hot water?

The answer is pretty obvious when you look at the picture. The molecules moved quicker in the hot water than the cold water.

Does food coloring mix faster in cold water or hot water?

Another simple, yet fun experiment completed!

Our Grand Pumpkin Experiment

I’ve mentioned that my family and I have been able to make pickles, can jalapenos, and make quick fresh salsa this summer using fresh ingredients.

Our garden is no longer nearly as large as it had been in the past since we moved last year, but we have still been able to enjoy jalapenos, cherry tomatoes, green peppers, cucumbers, green beans, sugar snap peas, and strawberries from the plants we have planted in pots on our deck.

We were even able to get a few zucchinis from a zucchini plant in a large pot on our patio. My daughters were so happy we had actually gotten a zucchini from a potted plant that they invented “Zucchini Harvest Day” on the day we picked the first zucchini.

It’s now time to enjoy pumpkins.

We don’t have pumpkins in our potted garden, but my grandparents recently gifted my daughters with two pumpkins from their garden. My grandma mentioned these pumpkins are specifically grown for cooking.

Since we had written “make a pie” on our fall activity list, we decided to attempt to make a fresh pumpkin pie using these pumpkins.

Maybe we’ve been doing too many scientific experiments lately because when I mentioned this would be our “grand pumpkin experiment”, one of my daughters reminded me that I needed to follow the steps of the scientific method in order to call it an experiment.

Jobs of a Preschooler- I'm a scientist...

“I’m a scientist…” from the book Jobs of a Preschooler

Well, my objective was to make pumpkin puree and create an edible pumpkin pie using the pumpkins we had been given.

My hypothesis was that we would successfully create pumpkin puree, and the pie would be edible but would not taste or look good, yet we would still have fun even if it didn’t turn out well. At least that way, I would either be right with my hypothesis or pleasantly surprised with the results.

I wasn’t sure what materials or procedure we needed to follow to make the pumpkin puree, though, so I did some online research.

We started by cutting the pumpkins open and scooping out the insides.

scooping pumpkin innards

As one of my daughters and I were scooping out the insides, my other daughter separated all of the seeds from the guts of the pumpkins.

Sorting through pumpkin guts

One of the ideas I found online for making pumpkin puree was to cut the pumpkin into strips and bake it. We decided to try that.

I had the pieces sitting with the peel side down, but they started burning, so I rotated them a few times while they were baking. I removed them from the oven when they were soft enough to peel and mash.

Baking pumpkin

One of the other ideas I saw online for making pumpkin puree was to remove the peel, cut the pumpkin into cubes, and boil the pieces. We decided to try that, too.

This technique reminded me of a combination of cutting a watermelon and making mashed potatoes. I used a colander to remove the water once all of the pumpkin pieces were soft. Then, my daughter mashed them in a large bowl using a potato masher.

Boiling pumpkin

We had more pumpkin pieces baking in the oven than boiling on the stove since I couldn’t fit as many pieces in the large pot as I could on the cookie sheets.

Our observations were that the boiled pumpkin seemed to soften quicker than the baked pumpkin. We were also able to mash it sooner since the peel had already been removed. I had to let the baked pumpkin cool for a little bit before I could remove the peel and mash it. I apparently didn’t let it cool long enough because I still managed to burn my fingers a little as I was removing the peel.

The mashed baked pumpkin pieces seemed more stringy and less moist than the mashed boiled pumpkin pieces. I was concerned the boiled pumpkin puree was going to be too moist for future recipes (especially if frozen first), so I ended up mixing the baked pumpkin puree and the (drained) boiled pumpkin puree together. I divided the puree into containers, so it could cool in the refrigerator.

Once we had our pumpkin puree, we were ready to make the pumpkin pie. I found a recipe on allrecipes for homemade fresh pumpkin pie using 2 cups of the pumpkin puree.

We read through the recipe, made sure we had all of the ingredients, and then watched a video on Youtube to see how to cut shortening into flour using the two butter knives method.

We successfully made the pie crust, but I managed to accidentally tear it apart as I was trying to put it into the greased pie pan. So, we rolled the dough flat again, placed the greased pie pan upside down on it, cut around the edges, and carefully peeled it away from the board we had used to roll it. Once peeled from the board, we flipped the pie pan with the dough in it. From there, we pushed the dough flat and pinched along the top edges.

It wasn’t the most gorgeous pie crust, but I considered it a success since I was able to get it into the pie pan without it falling apart again.

homemade pie crust

We had looked through the list of ingredients before making the pie, but we didn’t realize we only had about 1/4 teaspoon of ground nutmeg instead of the 1/2 teaspoon ground nutmeg suggested in the pumpkin pie recipe. So, we used 1/4 teaspoon ground nutmeg, and we decided to increase the amount of ground cinnamon to 1 teaspoon.

We also didn’t use an electric mixer or immersion blender like the recipe had recommended. Instead, we mixed the filling by hand with a large plastic spoon.

Mixing pie filling

Once mixed well, we poured the mixture into the pan. We actually had a little bit of extra mixture that didn’t fit in the pan, which I disposed of. We created a heart with the small amount of left over pie crust we had. Then, the pie was carefully placed in the preheated oven. I was thankful I managed to get it into the oven without spilling any of it.

precooked pumpkin pie

The result was that cooked pumpkin pie actually turned out much better than I had expected, so my hypothesis was wrong. It may not be the best looking pumpkin pie, but it didn’t look horrible and everyone in my family thought it tasted great. In fact, the entire pie was eaten in less than twenty-four hours by my family of four.

finished pumpkin pie

In conclusion, we were able to successfully make pumpkin puree and an edible, delicious pumpkin pie using the pumpkins my daughters were gifted. We were able to do this by researching information, following (and adjusting) directions, and working together.

But, we didn’t stop there.

We didn’t let those seeds my daughter had separated at the beginning go to waste. We soaked them overnight and then made two different kinds of baked pumpkin seeds. One included a mixture of butter, sugar, and cinnamon and the other was just salt.

2 kinds of pumpkin seeds

When the pumpkin puree was completely cooled, I divided it two cups at a time into six separate labeled freezer bags. I’m curious to see how well it will work in future recipes once it has been frozen. Hopefully, we will be able to replicate 6 more delicious pumpkin pies within the next few months with this puree.

pumpkin puree prepared to freeze

We had made a total of 15 cups of pumpkin puree from the two pumpkins. We used 2 cups for the pumpkin pie and packaged 12 cups in the freezer bags to freeze, so we had a total of 1 cup pumpkin puree remaining. Since I didn’t want to waste the extra pumpkin puree, I found a pumpkin muffins with cinnamon streusel topping recipe from allrecipes that required only 1 cup of pumpkin puree.

We made a total of 18 muffins using the recipe. They didn’t hold together very well when I removed them from the muffin pans, but they still tasted pretty good.

Personal Pizzas Kids Can Create

I recently wrote an article that was published in the Fall 2018 edition of The Old Schoolhouse magazine entitled Meal Planning: How to Save Time and Money. In the article, I discussed ways to prepare large quantities of ground meat, chicken hindquarters, pork loins, chicken breasts, ham, and turkey when bought on sale to simplify future meals while saving some money.

One of the tips I discussed was using ground meat to prepare and freeze homemade meatballs for future use. I really like that frozen meatballs can be tossed in a slow cooker with spaghetti sauce and cooked for a few hours for an easy dinner of meatball bombers – meatballs, sauce, and mozzarella cheese on a long bun.

Meatballs on Tray

I always add more meatballs than my family will eat in one meal to the slow cooker when cooking the meatballs since there is always extra spaghetti sauce. I use the leftover meatballs and spaghetti sauce for spaghetti (just prepare some noodles), or I let my daughters make their own homemade personal pizzas. These little pizzas are so simple for kids to make!

My daughters enjoy making and eating these tasty pizzas. Although we often make them when we have leftover meatballs and spaghetti sauce, they could be made any time with ingredients you have on hand. These are the typical ingredients we use when making these personal pizzas.

  • slices of bread
  • leftover spaghetti sauce (although pizza sauce would work)
  • leftover meatballs, cut into small pieces
  • shredded cheese
  • spices/ seasonings (optional)

I put the spaghetti sauce into a small bowl and the bread on a sprayed cookie sheet. My daughters scoop and spread the sauce onto the pieces of bread using a spoon. Then, my daughters layer the bread with the shredded cheese. Next, they put the leftover meatballs across the tops. Sometimes, they will also add other seasonings such as Italian seasoning.

personal pizzas kids can make

Once the little pizzas are assembled, I place them in the oven at 350F. Since the meat had already been cooked, I only have to cook the pizzas until the cheese is melted and the bottoms are slightly browned (about 10-15 minutes).

They may not be fancy, but these pizzas get the little ones involved with cooking while using up leftovers. Even little ones can be chefs like the girl in the book Jobs of a Preschooler!

Simple Science Experiment

(This post contains affiliate links, which means I may make a small commission at no extra cost to you if you click on the links and make a purchase.)

We have officially finished day two of school for the school year and so far everything is great.

No tears + No yelling + Completing our planned lessons = Great

We are eclectic homeschoolers, which means I pick and choose a variety of curriculum for our subjects. This year, we have decided to use Apologia Exploring Creation with General Science for our science lessons.

I’ve used Apologia in the past, but this is the first year I also purchased the companion notebook for each of my daughters. I am so glad I did! The notebooks definitely add to the reading since they require the students to answer questions, write sentences, and record science labs.


I’ve mentioned in the past that my daughters and I enjoy doing science experiments together at home. Well, today we had the opportunity to complete a simple science experiment for our science lesson concerning atoms and density.

Jobs of a Preschooler- I'm a scientist...

“I’m a scientist…” from Jobs of a Preschooler

If you would like to replicate this simple experiment, gather the following supplies:

  • tall clear jar
  • 2/3 c vegetable oil
  • 2/3 c water
  • 2/3 c corn syrup
  • small rock
  • grape
  • ice cube
  • piece of cork

Once you have your supplies, you can follow these steps:

  1. Pour vegetable oil in glass.
  2. Pour water in glass.
  3. Pour corn syrup in glass.
  4. Drop rock, grape, ice cube, and cork into glass.

Simple Science Experiment

So simple, yet fun to do. After writing the lab report in their notebooks, my daughters stirred the contents of the glass jar with a spoon to see what would happen.

I labeled a picture I took of the experiment for them to add to their notebooks along with their drawings of the different layers.
