The Three Types of Rocks– Our Activities and a Free Worksheet Packet about igneous, sedimentary and metamorphic rocks

A few days ago I shared the Rocks and Minerals Packet I made for ED. I wanted to spend more time on the three types of rocks–igneous, sedimentary and metamorphic rocks.  The kids were SO excited when they realized this activity was going to include semi-sweet chocolate chips, white chocolate chips, peanut butter chips, heath crunch bits and flaked coconut. (No we didn’t eat it all, but we did taste...

The Three Types of Rocks– Our Activities and a Free Worksheet Packet about igneous, sedimentary and metamorphic rocks

A few days ago I shared the Rocks and Minerals Packet I made for ED (which is also free). I wanted to spend more time on the three types of rocks–igneous, sedimentary and metamorphic rocks.  The kids were SO excited when they realized this activity was going to include semi-sweet chocolate chips, white chocolate chips, peanut butter chips, heath crunch bits and flaked coconut.

Planarian 1

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 it...

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...

Milk-Fireworks 2

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...

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...

Water-Molecule-Attraction 3

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...

Celery 2

Plant Experiments: Colored Carnations and Slurping Celery

ED has been learning about plants this past week or two.  We talked about the various parts of the plant and then read a bit in our science books about the function of the stem (and trunk) of plants.  We revisited an experiment we did 2 1/2 years ago — the celery slurping experiment — as I called it then! This time I bought a bunch of carnations to experiment with...

States of Matter – Solid, Liquid, Gas – Learning Activities

Are you working on chemistry this year? I thought I’d share some of the activities we did when we learned about the States of Matter. I also link to a number of other posts from our chemistry unit. We’ve been having a blast with chemistry — well not literally, but sure have been learning a lot! Today we did most of the hands on activities suggested by the wonderful, wonderful...

Preschool Science: Living, Nonliving

We’ve been having a discussion of what makes something living. Living things eat drink (need water) breathe grow reproduce We’ve been observing mealworms for the past couple weeks.  We saw evidence of their growth because they shed their exoskeleton. Yesterday we noticed they had transformed completely into darkling beetles! We’ve been keeping track of the growth of three sunflower plants out in the garden. Our sunflowers have grown an inch...

Ten Books My 4 and 6 Year Old Love

It’s been a while since I talked about the books we’re reading.  We have lots of books around, plus we check out lots of books from our local library (50+ at a time!). I thought I’d highlight ten books that have been on the repeated request list. While we’ve read other books in the past couple of weeks, these are the books that I have read again and again (and...

A Great Science Activity: Working with Mealworms

The science curriculum I’m using this year suggests letting the kids observe and work with mealworms. This is part of our discussion of what makes something living or not living.  I purchased some from a local pet shop and came up with a few activities for the kids to do as they observe and learn about their mealworms. Before I even uttered a word, I simply handed the kids their...
