Fossil Hunting

We love fossils!   I guess the fire was first lit in Australia.  My scientist friend told us about a creek south of Alice Springs where people have found lots of fossils. (See original post here: Fossils in Australia and the photos below.) We took the kids and made some great finds. Even my friend, Peter, was impressed!  LD was hooked on fossils!   Not too long after that we...

Whale Unit (and the Arctic) — Icebergs, Blubber experiment, Buoyancy and more

Whales are able to survive in the frigid waters of the Arctic. In this series of activities the kids and I explored how that is possible. First, not directly related to the whales themselves, we talked about icebergs. We took giant cottage cheese cartons and froze big blocks of ice.  One of those blocks had our wooly mammoth plastic creature. I had the kids guess how much of the ice...

Whale Unit (and the Arctic) – Migration, Echolocation, Baleen vs. Toothed Whales

One of the days we read books, I stopped frequently to explain things and do activities with the kids. Whale Migration: For example, we talked in quite some depth about whale migration from the Arctic down the west coast of North America and back again.  I pulled out an Arctic Pin map I made and the kids placed the various countries that make up the Arctic region. You can download...

Whale Unit (and the Arctic) – Buoyancy

Have you ever started a unit and then something else unfolds?  Well this is a unit I started to put together on the Arctic.  You might even recall that we covered Antarctica for a couple of days to lead up to this unit. The more we got into it, the more this turned into a full blown study of whales!  We spent more than a week reading, doing experiments and...

Preschool Geography

NAME THAT CONTINENT: One morning in collection (our group time) I brought out a beach ball globe. We took turns tossing the ball around the circle. Each time someone caught the ball they had to look at where their thumb had landed and had to name that continent. The kids quickly became silly, but we did manage to get a few rounds in for each of them. Another preschool geography...

Gardening with Kids

It’s that time of year again! Our dining room table and a second table are covered with dirt planters! Last week the kids and I planted some seeds together. The kids are always excited to watch the seedlings start to grow. You can tell the kids helped since there are so many seedlings in that one pot to the right!!       We also weeded and worked on one...

Brush Your Teeth! (another experiment)

A couple of weeks ago I saw some cute preschool activities about dental health at 2 Teaching Mommies, I was inspired!  We didn’t get to Amber’s ideas, but we did fit in the science activities from 1st grade with Miss Snowden. After talking about the germs in our house (see this post), it seemed fitting to talk about the germs in our mouths. I hard-boiled six white eggs and we...

Where do Germs Grow? 22

Germ Experiment — Where Do Germs Grow in Your House??!

Germ Experiment: When I saw this germ experiment, I knew we had to add this into our unit on First Aid. After all keeping ourselves healthy is as important as patching up the injuries, right?! The experiment called for gelatin, sugar and petri dishes. We didn’t have petri dishes so used paper cups and covered them immediately with glad wrap in lieu of a cover. Boil 1/2 cup of water...

First Aid Unit: Germ Lapbook

Our germ unit took about a week to complete in part because of the amazing germ-experiment we did (more about that next week… the experiment was awesome!).   We talked about the major types of germs: bacteria, viruses, fungi and protozoa.  While fungi can produce athlete’s foot and protozoa can cause giardia and malaria, we didn’t go into much detail about those. Some sources also consider helminths (worms) a germ as...

Astronomy Unit: The Moon (Day 2)

On this day we read about the Moon and did the lapbook components to add to our science notebook. What’s perfect about these lapbooks for us right now is the writing is not overwhelming and  reinforces the main points we’ve gone over.  We used the Moon — Speedy Lapbook by Homeschool Bits (which was quite inexpensive). Moon Craters: Our activity that day was to talk about why the surface of...

Astronomy Unit: The Moon (Day 1)

The moon is very far away (225,622 miles to 252,088 miles depending on its position in its elliptical orbit around the Earth). NASA had to be very careful about the calculations they made to send someone to the moon especially since the moon is a moving target.  In this activity, the kids are trying to hit the moon (a nut suspended on a string) that is swinging back and forth....

Astronomy Unit: Inner and Outer Planets, The Asteroid Belt

We seem to talk about the planets about once a year, don’t we?  This time we did a little activity that showed the four inner, rocky planets, the asteroid belt and the four outer planets, the gas giants. In this picture you can see that the asteroid belt has two layers as well! We did the inner and out planets speedy lapbook by homeschool bits (25cents) — and even ED...

Astronomy Unit: Refraction, Vacuum, Saturn’s Rings

The kids have been begging for some hands-on science experiments. I have a bigger unit planned, but since December and January will be a bit broken up as far as our schooling goes, I decided to delve into a short unit with lots of experiments based on one of Janice VanCleave’s books (202 Oozing, Bubbling, Dripping, Bouncing, Experiments) and lots of notebook/lapbook pages from Homeschool Bits. Here’s some of what...
