Hands-On Invertebrate Fun! (Part 2 – Amazing Planarian)

Planarian are a type of small flatworm. My homeschooling friend had some Planarian she had ordered and shared some with us! What a great friend to share her worms! 🙂 Heh heh! Let me first share a picture of these little creatures and then I tell you some really cool things about them!! Planarian are amazing because they have the ability to regenerate! If you cut a Planarian in half...

Hands-on Invertebrate Fun! (Part 1 – Earthworms)

Once we went over the classification of animals (I shared that post and our Montessori Activities here), we got into the exciting hands-on stuff!  We looked at earthworms and a type of flatworm called Planarian. There are some interesting differences in their body systems so we spent time comparing the two. Our first step was to go out to the garden and find ourselves some earthworms.  It was chilly out...

Meet Vertebrae-Man — Our Hands-on Explorations of the Backbone and Nervous System!

Continuing on with our vertebrate-invertebrate unit… One day last week we learned a bit about the backbone and nervous system. We talked about the importance and function of the vertebrae and did some activities to explore how/why the vertebrae work. The kids liked this almost as much as they liked Harold (when we did the circulatory system)!  Here’s a picture of vertebrae man–then I’ll explain what we did… I made...

Invertebrate-Vertebrate Unit Study – Montessori Activities

Homeschooling is so great because you can be flexible and go with the flow when the need arises! We were all prepared to start school with a unit on rocks when my wonderful homeschooling friend offered to give us some flatworms called Planarian. Her family had studied them and their amazing properties.  We jumped at the chance to do something new and delved into a week-long study of invertebrates. It...

Explosion of Colors in Milk Experiment and Other Chemistry Fun!

Isn’t this pretty? This was one of our experiments as we finished up our chemistry unit! One of the chapters in our chemistry book (Real Science 4 Kids-pre-level 1) talked about mixtures. It talked first about how how some mixtures dissolve (like salt in water). Then it went on to talk about soap and soap molecules. We read how soap makes things like butter and grease “dissolve” in water. Detergent...

More Fun Science Experiments: Watch them Bubble, Bubble Bombs… Acid-Base Reactions

Our chemistry textbook also talked about acid-base reactions.  It explained how antacids can help neutralize the strong acids in your stomach. We contrasted this slow reaction… to the more impressive reaction of baking soda and vinegar! DD was putting her fingers in to see how her stomach would feel. If you haven’t already done Bubble Bombs with your kids, be sure to do that as well! You take a ziploc...

Science Experiments: Red Cabbage Indicator (Fun for Ages 4 and Up!)

  We did a lot of Montessori science when the older kids were little, so this is an experiment we did years ago. Now the older kids are studying chemistry and ED is the perfect age (4) to enjoy the action of this experiment. Using red cabbage juice as the indicator, you add various household ingredients and compare it to an acid-base chart to see where that particular item falls...

Night Lights May Not Be Good For You or Your Kids

This isn’t breaking news, but it was new to me.  I’ve been trying to catch up on some reading of a magazine we get called Science News, when an article caught my attention. It said that sleeping in a room with even very dim artificial light such as a night light, computer screen or TV may cause changes in the brain and depression. The results of a study from Ohio State...

Good Viewing This Weekend: Orionid Meteor Shower 1

Good Viewing This Weekend: Orionid Meteor Shower

Don’t forget that on Oct. 21, the annual Orionid meteor shower will hit its peak, offering stargazers a change to see dust from the famed Halley’s Comet light up the night sky. The meteors are debris from this comet that enter Earth’s atmosphere and vaporize as they fall. Experts said that the best viewing will be before dawn on Oct. 20th and before dawn on Oct. 21st. That holds true no...

Building Molecules Chemistry Activity

We moved on from talking about atoms to talking about molecules and chemical bonds. Since my kids are pretty young, this is just a basic introduction to how bonds are formed and made. Building Molecules Worksheet: This is a free download. The screen shot below shows 2 of 3 pages. We spent several days building different kinds of molecules: On the first day we built water, oxygen, hydrogen and hydrogen...

Science Experiments: Water Molecule Attraction

Matter is made of tiny particles that are attracted to one another. We did a series of experiments activities from Middle School Chemistry (the free, downloadable chemistry course) that show that water molecules are, indeed attracted to one another. We first used a medicine dropper to see how much water we could push out of the syringe. We also examined the pictures of the droplets we managed to photograph in...

Chemistry: Molecule Movement Experiment and Chemistry Review Worksheet

We’ve been covering the states of matter, atoms and molecules in chemistry. I wanted review some of the information we’ve covered and made some basic worksheets for the kids. First, we went over the three states of matter and looked closely again at the parts of an atom. Molecule Movement Experiment: Then we did a simple experiment with water to show that water molecules can move at different rates. We...
