Human Body Eggsperiment: Protect That Brain!

Our last brain-related activity was to design a helmet that would protect our egg pilot in a fall. The shell, I told them, was his skull; the egg white and yolk was his brain. Then I left the kids to it! LD designed a balloon-encased egg protector.      DD designed a construction paper protective cloak: Mom designed a cotton ball-play dough helmet: I took the photo before covering it...


Human Body Unit: The Brain

We have been studying the brain in fits and spurts the last couple of weeks. For some reason, we’re only getting to it about twice a week. But here’s what we’ve done. We talked quite a bit about the functions of the brain (not the senses as we’ll do this later), but things like memory, thinking, sleep and thing like that. MEMORY: First we talked about the difference between long...

Heart Field Trip 3

Heart Field Trip

We don’t have a Magic School Bus, but we did make a pretty wonderful field trip this past (extended) weekend. One of our first stops was the Franklin Institute in Philadelphia. Part of the reason we studied the heart/circulatory system last week instead of going on to muscles and joints was to take advantage of the spectacular interactive science display at the Franklin Institute. You enter this huge heart on...


Human Body Unit: Heart and Circulatory System Activities

Our study of the heart and circulatory system started with a listen to our own heartbeats. We measured our heart rates when resting and after walking, running and skipping. Then using a graph put out by Texas heart institute(4th grade curriculum, p. 25, no longer available), we graphed our results. Heart as a Pump: We did this experiment: When your heart beats it acts like a tennis ball filled with...


This is the United States–Unit Study of Landmarks and Symbols

We have been working steadily on our USA landmarks and symbols unit study. This is a unit that doesn’t lend itself as well to pictures since I have pulled it together using history resources I have on hand. The kids each have a notebook and we’ve been adding to it steadily. Funny enough, LD has said he LOVES history and has been really into this unit.  That amazes me a...


Human Body Unit: The Hand

Our Study of the Human Hand Why do we have so many bones in our hand? We talked about the fact that there are 27 bones in the hand. First, to demonstrate why this is important I did an activity we had done a couple years ago. We pretended that we just had one bone per finger by taping popcycle sticks to their fingers.  Then they had to pick up...

Human Body Unit: Starting Off Again with the Skeleton 8

Human Body Unit: Starting Off Again with the Skeleton

 Last spring we started learning a bit about the human body, but then we stopped as summer activities took over.  We have re-started our human body unit. Before I knew I was going to luck into a zillion human body kits (see my post about being lucky!), I bought the Squishy Human Body by Smart Lab.  The kids just loved this!  We talked about how the skeleton protects all of...

Ocean Unit:: Cephalopods from Science Friday

My friend shared this really terrific video that talks a bit about how octopus and squid camouflage themselves by changing their skin color AND texture. It is astounding how much the octopus in the video blended into the bush. What an amazing world we live in! Please like & share:


Ocean Activities – diorama

We made the starfish, sand dollars, crabs and coral out of cornstarch clay. 1 cup cornstarch 1 cup baking soda 1/2 tablespoon salt 1 cup water Mix and cook on low to medium in a pot until it congeals together. We had fun putting this project together. I’ll share the various steps below: We spent one day painting our boxes. The girls then added glue and sand along the bottom....

Starting Our New Routine 5

Starting Our New Routine

Sorry about the endless postings about our ocean unit… just a couple more and that’s that!  Blogs are funny because they sure don’t show the whole picture. From looking at our blog our days are consumed by oceans!!  Heh heh! Well, that’s not at all accurate.  I read and read, planned and planned and finally the older kids started back to school last week. As you’ve seen, ED has been...


Ocean Animals — the real deal

Even though it was quite a drive for us, I decided a trip to the aquarium was in order with all our studies of ocean animals. We went last week. We sure had a terrific day! We all LOVED the jellyfish displays!   We were so lucky to see the octopus moving all around!       Everyone loved the sharks and we were lucky to see the sharks, sting...


Ocean Animals and Their Groups

I made this activity for my older kids (5 and 8).  You can download and print these sheets here: Ocean Animals and Their Groups  You can download and print these sheets here. There are two pages. You might want to make a colored circle on the back of each of the three related cards. Use a different color for each animal. That way, the kids can check their own work as needed. ...


Sewing Ocean Animals

We haven’t done that much sewing here at the Homeschool Den, so when I saw these cute projects over at future girl‘s blog I thought they’d be perfect. The kids each chose their own project. I thought they turned out pretty cute! DD made the octopus. LD made the jellyfish. ED made the fish. DD and LD did the sewing completely on their own, although I threaded the embroidery thread...
