A Fun Density Science Experiment!

It's time for Saturday Science again - I really look forward to Saturdays now! This link party is co-hosted by P Is For Preschooler, Lemon Lime Adventures, Suzy Homeschooler, The Joys of Boys, Little Bin For Little Hands, Stir The Wonder, and myself.

A somewhat random discussion this week led to this fun density experiment I threw together. I was trying to explain about density and I thought that the classic oil and water experiment but with a twist might illustrate the point best.

We've all seen the lava-lamp version of this, but I wanted something a little different so I froze colored water overnight before we tried it out.

Here's what happened when we floated the colored ice on top of some inexpensive cooking oil and let it melt.

Spring watercolor art lesson for kids

We saw a terrific and very easy spring watercolor art lesson that we couldn't resist trying out!

You'll need:
A straw
watercolor paints
watercolor paper
tissue or paper towel
cotton swabs

I've taken photos of our progress, but I won't share all the steps - you should check the original post for that.

The Science of Seatbelts: Car Crash Physics

The theme for Poppins Book Nook this month is Planes, Trains, and Automobiles (Grab your free lapbook for April from Enchanted Homeschooling Mom).

The Science of Seatbelts: Car Crash Physics

In the wake of a very scary accident my friend Christine had with her daughter, I thought that a good topic and experiment would be this one to show my kids exactly why we wear seat belts in the car. With summer coming up, I also wanted a reminder of why we don't leave rock-hard Nalgene water bottles all over the car after swimming lessons!

We borrowed the books below from the library. Max Axiom was a particular hit but they were all excellent reads! They gave explanations about forces and motion that satisfied both my 13 year old and my 6 year old.

I got this car crash physics experiment from our Supercharged Science curriculum. Here's what you need:

A car
A licensed driver
A tennis ball

Have your child sit in the back seat and put the tennis ball beside them (don't put it on the floor, as it might roll forward under, say, the brake pedal).
The Science of Seatbelts: Car Crash Physics

See how it moves on the seat as the car moves? Can they feel themselves moving the same way?

Drive along, not too fast, then stop suddenly in a safe place - warn your passengers first. What does the ball do? (The reason you don't go too fast is that you're probably not fond of tennis-ball shaped holes in your windshield!)

Explain to your child that everything in the car is moving at the same speed (for older students, that means it all has the same inertia.) When the car stops, everything in the car continues forward at that same rate of speed until it hits something that stops it. If the car turns, the ball keeps going in the same direction it had been going until it hits something that stops it.

We had trouble capturing the tennis ball in full flight, so we also repeated this with a stuffed animal at kid-head level.You can see it in the cover image.

Ask your child what happens if they are un-seatbelted and moving at 100kms/hr on the highway. Now imagine that the car stops. What would happen to them? Yep. That's why we wear seatbelts.

Simple Science Experiment: Build A Flying Contraption!

It's another Saturday Science! I co-host this every week along with Little Bins For Little Hands, Stir The Wonder, P is for Preschooler, Lemon Lime Adventures, The Joys of Boys, and Suzy Homeschooler.

This week, we tried out a super simple science experiment that we found in our Supercharged Science program: We built a flying contraption!

You will need an index card, scissors, tape, and a straw.

Slice the index card into thirds lengthwise.

Take two of the pieces of index card and tape them together to make a hoop shape, overlapping the edges a bit so it stays in a nice circle shape.  Use the last one to make a smaller hoop.

Tape the loops onto your straw (stand the hoops on end and slide the straw through them, then tape).

Hold the straw in the middle, with the big hoop at the back, and throw it kind of the way you'd throw a dart. It takes some testing, but you can get it to go pretty far.

Yes, my daughter's hair is frightening in this photo. In her defense, though, we'd just come back from a 2 hour bike ride.

Why does it fly? It doesn't look anything like an aeroplane! The answer, in a nutshell, is that the big hoop creates some "drag" (wind resistance) which keeps your flyer level, while the smaller hoop at the front keeps it flying straight. It doesn't turn over because objects of different weights still fall at the same rate of speed.

You can tweak this by changing the length of your straw, the size of your hoops, and the weight of your paper product. We've spent hours throwing these off the back deck!

If you enjoyed this experiment, you might want to try out this e-book of free experiments from Supercharged Science. We have found it to be the absolute best homeschool science program around.
