Weather Unit: Intro Notebook Pages (Free)

We finally started our (long awaited) weather unit! These are the pages we went over on our first day… it covers a few basics and some background about the history of meteorology.  I also rounded up some interesting weather facts and we read through those as well.

Then we’ll be jumping off into a study of the atmosphere before learning about air pressure, weather fronts and all that.

They are free to download just click on the link below. The answers are included, but are not pictured below:

Weather Unit Intro and Cool Weather Facts

Follow along with our weather unit and hands on activities! Coming next Monday (April 20) is the (free) 19 page packet on the Earth’s atmosphere. Plus, more free printables to come…

Free Easter Multiplication and Division Worksheets

Although a lot of the schools around us are having spring break, we have a family vacation coming up in another month so we’re homeschooling this week.  Over the weekend, I made some multiplication and division pages for DD and LD to practice their math facts. You can download this free by clicking on the link below. There are 3 pages.

EggSperiment: Brush Your… errr… Egg (Part 4 of 4) and the Free Printable EggSperiment Pack

This activity helps kids understand how very important it is to brush your teeth every day!

For this activity we chose coke, grape soda (we didn’t have any grape juice) and coffee. You can use any beverage that you think will stain your teeth.  The kids each selected two drinks and we let the eggs soak for several hours.

As the kids “brushed” their eggs, they were amazed at how quickly and easily the “stain” came off.

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 breathe?

Have the kids discuss this. Then take an egg and place it in warm water or vinegar. Have them watch as bubble form around the egg and start rising towards the surface.

Eggs are porous:
• Eggshells have to have little holes in them so that air can move through and into the egg for the growing baby bird. This lets the growing embryo get oxygen.
• We can see evidence that there are little holes in an eggshell by putting it in water and seeing air bubbles. Air can not only get into the egg, but come out of it, too.

Eggs and Pollution

We then talked about how since it is porous it can let things through — like acid (vinegar), acid rain and pollutants. We talked about DDT (how eagles nearly became extinct)– and how poisons, pesticides and so forth can harm the animal populations. Also, this means that eggs can take on the smell/flavor of things around it so it is important to keep eggs in their carton in the fridge so they don’t begin to smell like stinky cheese!

Egg Activity #6

Chick Development

After talking about the growing chick embryo, we brought out this set I made a few years ago. You can buy the same thing (for example Learning Resources makes a set), but since we only use it for 10 minutes once every couple of years, it wasn’t worth the $30 price to our homeschooling family. Instead I bought some wooden eggs from a craft store and printed pictures out from the Internet.

EggSperiment #8

Is this egg hard boiled or raw?

Give the kids a hardboiled egg and a raw egg and have them try to figure out which is which. Suggest that they spin them around. Can they figure out which is which?

If the egg spins well, it is hard boiled. If the egg spins and wobbles slowly, it is raw. Since the raw egg is fluid inside, its center of gravity changes as the egg spins around. This results in the wobbling motion.

If you touch the eggs slightly to try to stop them, the raw egg will continue to spin for just a moment. That’s because of the inertia of the fluid in the egg.

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 were round, they would probably roll out of nests or too far away from the mother hen.

Egg Activity #2: Why are eggs shaped the way they are?

Place an egg in the middle of your palm. Squeeze as hard as you can. Can you break it?

 

LD was certain he would be able to crack his egg immediately. He was shocked when he couldn’t and begged to be allowed to throw the egg on the ground instead!

The arch is one of the strongest architectural shapes and similarly, the ovoid shape gives an egg its incredible strength!

If you look at the roof of the Pantheon (in Rome) it is shaped like an egg. It has survived for more than 2,000 years. That’s because when weight is applied, no single point in the dome supports the entire weight. Instead, the object’s weight is carried down along the curved walls to the dome’s base.

Egg Activity #3: So if eggs are so strong, can you stand on them? Try it!

If you’re careful you can! But of course, if the egg breaks it’s probably because you applied greater pressure to the shell than it could bear!

Just so you know, I had to lift the kids up slightly and have them set their feet down rather than “walking” along the egg. We didn’t have enough eggs on hand to chance them all smashing before the third person had a chance. And yes, the eggs were raw not hard-boiled!
