Egg-tivity: Seatbelt Safety to Protect an Egg

Wednesday, July 23rd, 2014

While LD was away at summer camp, the girls did a few egg-tivities of their own. First in preparation for the activity, they made their own pinewood derby cars (just kits that we got from Michaels).

Once the paint was dry and the wheels were on, I told them they had a challenge… to create a seatbelt safety system to protect an egg as the car traveled down our steep driveway.  DD experimented with a couple different options. First she tried using pipe cleaners:

When she couldn’t get the egg from popping forward, though, she opted for a rubber band system instead.

Although her egg stayed in place, her egg did not survive the bumpy ride down the hill. To be fair, though, her egg had a slight crack to begin with (from rolling off during the seat belt adjustment phase!).

She gave it a second go with a pom-pom addition (I”m not quite sure what the pom-pom was for)… but egg pilot #2 came to a bitter, sad end as well! She really had a blast with this activity despite the sad end for her eggs!

Meanwhile, ED declared she wanted a kitty to ride her car instead. Kitty made many, many safe trips down our driveway for an entire afternoon of fun! That’s what it’s all about, right?!!
If you’re looking for other egg-tivities, we had a ton of fun with eggs around Easter.  Be sure to visit those posts and download our entire Egg-speriment pack.

 

Have fun and see you next time! If you try these out at home, we’d love to hear from you at our Homeschool Den Facebook page!

Free Weather Packet

Tuesday, May 13th, 2014

Yesterday, I shared some of the science experiments we did about air. We learned that air has weight, hot air rises and more.  We are using a science textbook as the spine of this unit. These were the pages I made for the kids’ science notebooks. You can download them free by clicking on the link below:

Weather Unit: Experiments about Air

Monday, May 12th, 2014

Last week we had a lot of fun with our Weather Unit.  The kids always love when we do science experiments and this part of our unit had a ton of demonstrations.

Air has weight:

This first activity is pretty self explanatory. We made sure that two balloons balanced. Then we blew up one balloon. It was clear immediately that the blown-up balloon was heavier.

Clear or Cloudy Day:

The next activity was supposed to show whether the air heated up more quickly on a clear day or a cloudy day.  Then we were supposed to check to see which lost heat more quickly (we forgot to go back outside late in the day, though).

Warm Air Rises:

This was by far our favorite experiment! It worked so well. First we spent quite a bit of time talking about the movement of air… how warm air rises and cool air sinks. We talked about the term “convection.” We also talked about how in warm air, the molecules expand and with cool air the molecules are closer together. This makes cool air “heavier” than warm air. We read the section in our science book that covered this movement of air and drew pictures for our science notebooks.

For this experiment I had a glass bottle that was cooled in the freezer.  We put a balloon on top and then set the bottle in boiling water.  We were shocked how quickly the balloon shot up and filled with air! In fact, it all made us jump!!

The kids loved this so much that we got out a bowl of ice water and they took turns moving the bottle from the cold water to the hot water and back again. They were surprised how quickly the balloon expanded when they placed the bottle in the hot water, but how long it took to deflate again when placed in the ice water (by comparison).

Tomorrow we will share the notebook pages I made for the kids for this portion of our unit. The Weather Packet will be free to download. We have some experiments we have yet to do relating to air pressure.  We hope to get to those in the next week or so.

Free Earth Science Packet: Earth’s Atmosphere (19 pages)

Monday, April 21st, 2014

We are embarking on a study of Earth’s weather, wind and water this spring. To get started we needed to review some of the basics of Earth Science.  We’ll start with a review of Earth’s four systems: the geosphere, hydrosphere, biosphere and atmosphere.

We reviewed a few things we’ve already studied about Earth’s system and then are going into depth about the Earth’s atmosphere.  We’ll spend quite a bit of time on the layers of the atmosphere.

We will be covering all the layers of the atmosphere (the troposphere, stratosphere, mesosphere, thermosphere and exosphere). And we’ll be doing a number of hands-on activities about air and air pressure (more about those in coming posts!)

It took us a few days to go through the first pages of the packet.  Then after we talked about the four layers of the atmosphere, we watched the BBC Program: Power of the Planet, Atmosphere

and the kids all put together their own layers of the atmosphere (which is in the packet):

Below is a screen shot of the packet of materials for the kids.  I included some of the general notes and activity ideas I am using with the kids. The packet is 19 pages. I included a couple of the pages in different formats so you could use them as needed in your homeschool or classroom. As always, it is free to download.

Remember that if you are a teacher using your school’s email, you will probably have to use your private google account to access this file. Most school email systems won’t allow access to google docs and won’t let me add you to the “share” settings.  You can also email me to request the file and I’ll do my best to get it to you. ~Liesl
