4 More Science EggSperiments: (Part 3 of 4)

EggSperiment #4 Will an egg float or sink in water? What happens when we add salt to the water? We added a lot of salt to one cup and had plain water in the other cup. The egg in salty water floated, while the other egg sunk. We talked about why that was the case and how salt molecules changed the density of the water. Egg Activity #5 Do eggs...

3 More Quick EggSperiments: How Strong Is That Egg? (Part 2 of 4)

EggSperiment 1: Why do eggs move the way they do? Have the kids roll an egg around on a table. Talk about why they are shaped the way they are.  Because eggs are a funny and oblong shape, they roll and wobble around in a certain way. Eggs wobble when they roll so they won’t go far from a mother hen and they will stay inside of a nest.  If eggs...

That’s just a fancy way of saying… a bit of this and a bit of that.  They’ll do both non-fiction and fiction writing selections, art projects, geography and habitat projects. And they’ll also watch a number of videos and/or movies.  You’ll get a...

Montessori Cards: Vertebrates-Invertebrates; 5 Vertebrate Groups

It is animal week for my youngest daughter. We’ve been touching on vertebrates and invertebrates since the kids were little, but I wanted to go back and make sure ED really knew the characteristics of these groups and how animals are classified. First, we went over the difference between Vertebrates and Invertebrates again. We brought out our model frog skeleton again for a closer look! Then she went over the...

Science Experiment for 2-8yr olds: Make a Color Explosion in Milk!

The kids participated in a science fair event a couple of weeks ago… where kids and adults could share their favorite science-related collections, photos, experiments, and knowledge. Some adults set up a slide show of their astronomy photos, sharing bone collections, a cartographer shared some of her materials, kids brought in their rock collection and more… My kids  set up a science activity station with the Color Explosion in Milk....

Free Engineering Curriculum Available Right Now (Grades 3 to 8)

There is an amazing engineering curriculum that is put out by the Museum of Science, Boston. It’s called Engineering is Elementary.  My friend first told me about their hands-on curriculum units and we actually have two of their units lined up for the next month or two. Why study engineering? Their website explains it this way: Hands-on, project-based learning is the essence of engineering. As groups of students work together...

Beat the Cold with these Science Experiments about Ice, Blubber and More!

Today many of the public schools are closed because of the incredible cold front that has come sweeping through.  I thought I should share some science experiments we did that might really get kids intrigued about the cold weather! Icebergs: Freeze water in a cottage cheese or large yogurt container. In one of the cartons you can place a wooly mammoth plastic creature if you have one! Have the kids...

Preschool Science at Home

Five or six weeks ago, someone asked me how I go about setting up our science units. I wanted to spend some time really laying out that process. Since we have homeschooled from the start, I thought it would make the most sense to talk about the preschool years first. (Click here to see the second post in the series: Science in the Elementary Years. Science in the preschool years:...

Our Favorite Simple Machines Activities– Pulleys (and Wheel and Axle)

The last day of our Simple Machines unit was probably our favorite. We spent hours and hours making and toying with different ways of making pulleys and wheel-n-axles! We started (as always) by reading a couple of books.  We did an activity to show investigate which way of looping the rope made it easier/harder to pull the broom-handles together: The kids really enjoyed Pull, Lift, and Lower: A Book About...

Simple Machines Unit: Screw Hands-On Activities

We started with… a plain old screw!! The kids spent time trying to screw it into an old board:   We have been reading the book, Archimedes and the Door of Science along with this unit. What a terrific book and what a remarkable man Archimedes was!  The book talks about the Archimedes screw as well as lots of other topics — astronomy, math, geometry and more. We loved the...
