Earth Science: Plate Movement Hands-On Activities

We just love hands-on activities! We’ve been studying Earth Science this fall.  Back several weeks ago, we explained how we started this unit… with an overview of our solar system, then a closer look at Earth’s geologic timeline talking about the age of the Earth (4.6 billion years) and the appearance of various critters in the geologic timeline (trilobites, sharks, dinosaurs, ants and more). We also l learned about latitude, longitude...

Spooky Science: Dry Ice Experiments

A couple of years ago, we did some spooky science with dry ice. We’re going to do some of these activities again this week, but I thought I’d share some of the things we did then in case you want to try these activities with your kids. I went out and bought some dry ice and we did a number of experiments. You can see suggestions from Steve Spangler science and a...

Earth Science: Layers of the Earth Hands-On Activity

Last week, I mentioned that we learned a bit about the Solar System in general.  This week we’ve been looking more closely at Earth’s long history.  We’ve been going over the four major eons and looking more closely at what happened in each (Hadean Eon, Archean Eon, Proterozoic Eon, Phanerozoic Eon). At first 4.6-4 billion years ago, the Earth would have been molten. Then as the Earth cooled it went from liquid...

Egg-tivity: Seatbelt Safety to Protect an Egg

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...

Free Weather Packet

Today I’m going to share some free weather worksheets I made for the kids.  This is for our study of the weather: the uneven heating of the Earth and how that affects our weather, fronts, and more! 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...

Air Has Weigh Science Experiment 7

Weather Unit: Experiments about Air

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:...

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...

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...

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...

Science Experiment for 2-8yr olds: Make a Color Explosion in Milk!

The kids participated in a science fair event a couple of weeks ago… where kids and adults could share their favorite science-related collections, photos, experiments, and knowledge. Some adults set up a slide show of their astronomy photos, sharing bone collections, a cartographer shared some of her materials, kids brought in their rock collection and more… My kids  set up a science activity station with the Color Explosion in Milk....

Free Engineering Curriculum Available Right Now (Grades 3 to 8)

There is an amazing engineering curriculum that is put out by the Museum of Science, Boston. It’s called Engineering is Elementary.  My friend first told me about their hands-on curriculum units and we actually have two of their units lined up for the next month or two. Why study engineering? Their website explains it this way: Hands-on, project-based learning is the essence of engineering. As groups of students work together...

Beat the Cold with these Science Experiments about Ice, Blubber and More!

Today many of the public schools are closed because of the incredible cold front that has come sweeping through.  I thought I should share some science experiments we did that might really get kids intrigued about the cold weather! Icebergs: Freeze water in a cottage cheese or large yogurt container. In one of the cartons you can place a wooly mammoth plastic creature if you have one! Have the kids...

Preschool Science at Home

Five or six weeks ago, someone asked me how I go about setting up our science units. I wanted to spend some time really laying out that process. Since we have homeschooled from the start, I thought it would make the most sense to talk about the preschool years first. (Click here to see the second post in the series: Science in the Elementary Years. Science in the preschool years:...
