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...

Last Minute Girl/Boy Gift Ideas for 4-8 year olds ($5-15)

There are so many last minute gifts to get…your child’s secret buddy, your niece,  your neighbor’s son, the giving tree or your child’s best friend. Here are a couple of unique gifts we’ve given out because they were such HUGE hits with our own kids. 4- to 8-year-old girl The past month, my kids have been obsessed with fuzzy felt friends. We sent this kit as a gift to my 5-year-old (almost...

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...

Celery Experiment 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...

Chemistry Unit: The Size of Atoms

We started our chemistry unit a couple weeks ago.  We’re doing lots of reading and really enjoying the books in the NOEO curriculum. We loved, What’s Smaller Than a Pygmy Shrew?  (affiliate link)  It takes a look at protozoa, bacterium, molecules and atoms — even talking about electrons, protons and neutrons. After we read through the book the kids drew pictures of protozoa. (LD’s picture is on the left, DD’s is...

Honoring the Mars Exploration Team and How You Personally Have Benefited from the Space Program

Later today, the mission team for NASA’s long-lived Mars Exploration Rovers Spirit and Opportunity will be awarded the Haley Space Flight Award.  Mars Exploration Rover Project Manager,  John Callas,  will accept the award on behalf of  the team. Previous recipients of this prestigious award have included Alan B. Shepard, John Glenn, Thomas Stafford, Robert Crippen, Kathryn Sullivan and the crew of space shuttle mission STS-125, which flew in 2009 on the last shuttle...
