I have to say that I have found it much more interesting to teach science as a homeschooler than I did to learn science as a student. I want my kids to love learning and so in my quest to make science engaging, I look for hands-on activities that will help my kids to retain what they learn. When we were learning about the Earth, we found some awesome science experiments!

Doing these hands-on activities made learning about the Earth interesting and helped the kids to understand the concepts much better than if all of our unit had been reading out of a textbook.  Their favourite ones seemed to be the ones about natural disasters such as earthquakes, tornados and hurricanes. Personally, I found the groundwater one to be the most interesting as it was something I didn’t know before.

This year, we have been using the science curriculum CKE Earth & Space. We have studied the Earth’s layers (see our Layers of the Earth model here), tectonic plates, volcanoes, earthquakes (see our easy earthquake experiment here), rock types, oceans, and the water table. This was one of the book’s hands-on activities for demonstrating the concept of groundwater.

Materials needed:

2 large clear glasses or vases
sand
gravel (we used aquarium gravel that we had left over from our History Sensory Bin)
pitcher of water

In each of the glass containers, layer sand and gravel alternating between the two until they are about 3/4 of the way full. This will create an aquifer. An aquifer is the layers of rock, soil and sand that contain water.

Slowly pour water into one of the containers, having your kids observe how the water is making its way through the small openings as it goes down.

In the first container, continue pouring until it is full (above the aquifer).

Next, slowly pour water into the second container, stopping about an inch BELOW the top of the aquifer. The level of the water in the second container is the water table. Below that, the aquifer is saturated. The glass of the container in this demonstration acts as impermeable rock.

Create what would happen if it were to rain by very slowly adding a bit more water to the second container. Have your kids observe and write down their observations. This demonstrates the recharging of the groundwater.

We kept our containers for a few weeks so that the kids could see that in the first one, there was never any room for more water, but in the second, as the ground soaked up more of the water and as time passed, we were able to add in a bit more water at a time as long as we never filled it above the top of the aquifer.

Vocabulary words that may be helpful in learning for this lesson:

groundwater, water table, aquifer, saturated, impermeable

Layers of the Earth Hands-On Science Activity

Gravity Defying Beads

10 Jello Science Experiments

Melting Ice Experiment

We are still really enjoying our new science curriculum, CKE Earth & Space. In the past few weeks, we’ve been learning about the Earth’s layers (you can see our Layers of the Earth model here), tectonic plates, volcanoes, and earthquakes. This was one of the hands-on activities suggested to go with the teaching on earthquakes.

Materials needed:

metal cookie sheet
wooden blocks
Lego bricks

First the kids constructed a tower on the cookie sheet using the wooden blocks. Then two of the girls sat on either side of the cookie sheet and shook it as if there were an earthquake. Not surprisingly, the tower crumbled with very little shaking and the blocks fell.

The metal cookie tray is meant to represent a tectonic plate and the shaking represents the shifting that happens with an earthquake.

Next, we all worked together to construct a tower with interlocking Lego blocks. The kids, our boys especially, are always excited when Lego and school collide! We made it approximately the same height and shape as the wooden block tower. It took much longer of course to make the Lego brick tower, which led to a discussion about how sometimes doing things the right way takes more time.

We set the new tower on the cookie sheet and the same two girls got on either side (in order for the experiment to be as scientific as possible, we wanted to use the same people so they could attempt to create the same earthquake force). At first, the girls recreated the same shaking they had the first time and the tower stayed intact.

They became more and more forceful with the shaking, eventually lifting the tray up and banging it up and down as well as side to side before they were able to knock the tower over and dislodge a few of the bricks.

This simple earthquake experiment was an easy way to demonstrate to the kids why buildings in earthquake prone areas need to be built differently to withstand the fallout of the quakes.

Layers of the Earth Hands-On Science Activity

Make Your Own Windsock

10 Jello Science Experiments

A few weeks ago, the kids were learning about wind turbines in homeschooling. This naturally led to some discussion on wind direction and wind speed, so I decided that we should make a windsock to help demonstrate both concepts.

I was able to use items that we had around the house already which not only make this project inexpensive (free actually!), it also had the added element of making it a reuse project as well.

Materials needed:

1. one large blue recycle bag
2. one empty plastic container such as a yogourt or sour cream tub
3. clear packing tape
4. string or yarn
5. optional: ribbon or streamers to decorate

Note: you will also need scissors and either a hole punch or the tip of a sharp pencil

Instructions to make your own windsock:

1. Cut the rim off an empty plastic yogourt or sour cream container to create a ring (see picture below).
2. Lay out a blue recycle bag and keeping one corner intact, cut it into a large triangle. You will now have a blue cone.
3. Put the cone into the ring you created with the open side up, pulling almost all the way through. Wrap the edge of the bag over the ring and tape into place with clear packing tape.
4. Snip the end off the corner on the bag (now the end of the cone) so that the wind can pass through.
5. Hole punch the bag right near the ring. If you don’t have a hole punch, you can use the tip of a pencil.
6. Loop a piece of string around the ring (which now has the blue bag attached) through the hole you just made and tie a double knot. Leave a long end on the string.
7. Tie the long end of the string to a post or high railing outside.

Now that your windsock is assembled, you can use it to observe and record wind speed and wind direction. The wind direction will be the opposite of the direction the windsock is pointing. So if the cone is pointing north, the wind is blowing south. This is a great way to also talk about compasses and to have your kids get some practise with direction.

Wind speed can be gauged by the windsock’s angle relative to the pole it is attached to. When there is very little wind, the windsocks droops and at high wind speed, it flies horizontally.

This homemade windsock obviously won’t be as accurate as the real ones, but it will give kids the chance to observe and make record of their observations from day to day or even compare wind speed or direction at different times of the day and see if they can find any patterns. This can create many different science experiments as their interest is peaked.

My kids were surprised at how easy it was to make our DIY windsock. I was surprised that it actually worked!
