What happens when you have weird-shaped objects, and you want to know their volume? Find out a clever way to do just that! We will be measuring the volume of a solid in our experiment today. My younger two children are using Christian Kids Explore Chemistry by Bright Ideas Press, and this is one of the fun experiments in the book.

Grab three interesting-shaped rocks from your backyard, and label them A, B, and C with a permanent marker. Grab a glass measuring cup and pour 300 ml of water into it. Now you will want to place one rock into the water. Measure how much the water went up. How high is the water now? Write it down. Then subtract the number from the original number (300 ml). You will find out the volume of the rock! Whatever amount of water the rock displaced is the amount of space it filled up, or its volume.

Remove Rock A from the water and measure Rock B in the same way. Was the rock smaller, larger, or the same volume? What about Rock C? Our third rock had the largest volume of the three rocks.

Measuring the Volume of a Solid Experiment

Now you can see how we performed this fun experiment:

Make sure to write down each of your measurements on the chart provided in the book. It helps if you clip the page to a clip board so that you can write your measurements as you are doing the experiment. If you want, you can doodle all over the rest of your page, as if you were a mad scientist!

Jonah Unit Study

October 10th, 2014

jonah-unit-studyMy kids had a great time with our Jonah Unit Study. We re-enacted the entire story on video, which you can watch inside the Unit Study Treasure Vault.

First Jonah was on a ship trying to escape from the Lord, going the opposite way of where God told him to go, to Tarshish instead of Nineveh. The ship was the back deck, and when Jonah was discovered sleeping, the captain woke him up. Everyone on the ship picked straws to see whose fault the storm was. Jonah picked the shortest straw (or pine needle, in our case). Then the kids threw Jonah gently off the side of the deck, where he splashed into the grass water. He swam for a while in the grass water of our backyard.

jonah-drawingJonah sank lower and lower into the water until he was swallowed by a large fish. In our case, it was the dining room table with a dark blue sheet over it. The children cut out teeth and taped them to the top of the table. The bottom teeth were taped together and taped to the sides of the table legs. We added a decorative spray that you can buy around the Fourth of July. We stuck the spray into a narrow flower vase.

jonah-drawing-for-kidsJonah prayed while he was in the belly of the great fish or whale. God spared his life for 3 days and 3 nights, and then the whale vomited Jonah onto land. Ptooey!

My son vomited himself out of the whale by jumping through the teeth. I told him not to be afraid to tear through the teeth. Jonah looked up as God commanded him once more to go to Nineveh. He finally obeyed.

jonah-and-the-whaleJonah preached one sentence, “In 40 days, God will destroy this city.”

He walked away. The people all repented in dust and ashes, so God relented and did not bring calamity. Jonah was upset with God because of His mercy toward these brutal Assyrians. He sat at the top of a hill overlooking Nineveh, and God caused a plant to grow overnight and give him shade. Suddenly a caterpillar ate the plant, and Jonah cursed the heat and wanted to die. God was mad at Jonah for being sad at the demise of a plant that grew up overnight, but not at the impending destruction of a city. Thus ends the book of Jonah.

Daniel Unit Study

October 8th, 2014

daniel-unit-study

For our Daniel Unit Study, we dramatized many of the events, drew pictures, and made interesting crafts. These are some of the most famous stories in the book of Daniel:

  • Daniel and his Friends Brought to Babylon
  • Nebuchadnezzar’s Dream: Prophetic Statue
  • Fiery Furnace
  • Nebuchadnezzar Goes Insane
  • The Writing on the Wall
  • Daniel and the Lion’s Den
  • The Visions of Daniel: End Times

Daniel and his Friends Brought to Babylon

When the book of Daniel starts, Nebuchadnezzar has just captured Jerusalem and set it on fire. He takes the court officials, the best of the best, back to his palace in Babylon. Daniel and his three friends are some of these youths. They decide not to defile themselves with the king’s food, and they end up being healthy and the wisest in the kingdom.

Here is a video clip that will help you to envision this event:

Nebuchadnezzar’s Dream: Prophetic Statue

King Nebuchadnezzar has a dream which no one can interpret. He demands that the magicians and wise men tell him what his dream was. When no one answers him, he gives an order to kill all the wise men in Babylon. Finally Daniel steps forward and interprets the dream. You can make a model of the statue from Nebuchadnezzar’s dream. The directions for this activity are here: Prophetic Statue from Daniel.

Fiery Furnace

fiery-furnace-drawing

Soon after having a dream about a statue, King Nebuchadnezzar makes a large gold statue of himself, which he forces everyone to bow down and worship. When Shadrach, Meshach, and Abednego refuse to bow to the statue, the king becomes so angry that he throws them into a furnace. But God miraculously saves them. To find out how to make a diorama about this story, click here: Fiery Furnace Craft.

Here is a video clip that will help you to envision the Fiery Furnace event:

Nebuchadnezzar Goes Insane

King Nebuchadnezzar is so prideful that God strikes him with insanity. He chews grass. After a while, he regains his sanity and praises and glorifies God. One of my sons drew a picture of the king going insane and eating grass.

nebuchadnezzar-eating-grassThe Writing on the Wall

The next story is Belshazzar’s Feast, where Belshazzar is using the utensils and goblets from the Temple. A disembodied hand writes on the wall, and Belshazzar frieks out. Daniel interprets the writing, and it is a prophecy that Belshazzar would be conquered. He is conquered that very night! My oldest son drew a picture of the writing on the wall.

writing-on-the-wall

Here is a video clip that will help you envision the scene of the writing on the wall:

Daniel and the Lion’s Den

Daniel begins serving the new king Darius, who has conquered Belshazzar. The people in high positions in government are jealous of Daniel and have Darius pass a decree that anyone who prays to anyone other than the king will be cast into the lion’s den. Since Daniel prays three times a day with the windows open, he is arrested and thrown into the lion’s den. But God saves his life by stopping the mouths of the lions, and the conspirators are eaten by the lions instead.

If you would like to do this simple craft about the story, you can find it here: Daniel and the Lion’s Den.

The Visions of Daniel: End Times

The final chapters of Daniel include prophecies of the End Times that fit into the book of Revelation. Daniel is reading the book of Jeremiah when he finds out that 70 years had expired, and that the Jews were supposed to return to Jerusalem after 70 years. Daniel prays and confesses the sins of his people, and he lives to see the day when Ezra takes the first group of thousands of Jews back to Jerusalem to rebuild the Temple:

#10 Dissolving Calcium with Acid

October 6th, 2014

Today we will be doing an experiment where we are dissolving calcium with acid. We are using Christian Kids Explore Chemistry by Bright Ideas Press to study elementary-level chemistry. This is one of the fun hands-on activities in the book.

You will need a raw egg, vinegar, and a mason jar. Place the raw egg into the mason jar. Now pour vinegar over the egg until it is completely covered. You might want to put a little extra vinegar over it because the vinegar will evaporate somewhat. Now leave the jar alone for 24 hours.

egg-experimentsIf you look at the egg as it sits in the water, you will notice small bubbles surrounding the egg. This is the acid from the vinegar eating away at the calcium carbonate that makes up the shell of the egg.

After 24 hours, grab the egg gently in your hand. How does it feel? My daughter says it felt soft and squishy. The shell had been eaten away completely by the acid in the vinegar!

You will want to watch the video to see whether the egg in this condition will bounce or splat!
