Summer Science - AIG Machines and Motion Units 5 and 6

I respectfully ask that you not pin pictures of my children to Pinterest. Thank you!

We're finishing AIG's Machines and Motions. In unit 5, we learned about circular and periodic motion by observing circular motion,

Nobody got wet! :)

playing with a gyroscope,

observed spring action,

"Slinky, slinky, it's such a wonderful toy..."

and making a pendulum.

We skipped observing centripetal force but we discussed the experiment.

In unit 6, we learned about the use of machines by trying to create a structure using toothpicks instead of hands to lift the blocks.

We skipped building research in lesson 31, observing natural machines in lesson 32, and scientist research in lesson 34.

And with that, we finished our summer science. Woo-hoo! 

Soprano will have an easier school year which I'm sure she'll enjoy. Tenor will have another science during the year but it doesn't look too intense. We'll see how it goes... we start on Monday!

Summer Science - AIG Machines and Motion Units 3 and 4

I respectfully ask that you not pin pictures of my children to Pinterest. Thank you!

Continuing with AIG's Machines and Motions unit 3, we learned about kinematics by
understanding frame of reference, measuring speed and velocity, observing acceleration caused by gravity. I'm not sure why I don't have pictures of any of the experiments. ?
We skipped a few things that seemed like they'd be too hard to do. We didn't do the second half of the frame of reference because we didn't have a wagon big enough to put a person in; we also skipped the relativity poster in lesson 20.


In unit 4, we started exploring dynamics (laws of motion, gravity, falling bodies) by observing inertia.

When you flick the card, the coin drops straight down into the cup due to its inertia.

We explored the second law of motion,

experiencing the third law of motion,

 

and played with gravity.

 

 We did an egg drop,

Soprano's design

 

Her design was unsuccessful.

Tenor's design: 4 small, inflated balloons in the bottom of the box; the egg wrapped in bubble wrap; 4 inflated balloons attached to the corners of the box

 

Tenor's design was successful! He gave credit to watching MacGyver.

determined whether mass affects how fast things fall,

and understood center of mass.

We didn't use the green experiment from lesson 26 but did this balancing bird instead.

We also skipped the green experiments in  lesson 21 and lesson 23.

Summer Science - AIG Machines and Motion Units 1 and 2

I respectfully ask that you not pin pictures of my children to Pinterest. Thank you!

Our last book! For the second half of our physics study, we used AIG's Machines and Motions. For unit 1, we learned about mechanical forces by
playing with potential energy,

watching energy transformations,

 

observing momentum,

 

making a Newton's Cradle,

This did not work well and was not easy to put together. I would recommend finding one at a science museum to observe or buying one at a gift shop if you're able.

testing forces, measuring friction,

and performing work.

 

 

In unit 2, we started exploring simple machines by using a wedge, making a screw,

 

comparing screws,

experimenting with levers,

examining wheels, comparing rolling and sliding friction,

 

and experimenting with pulleys.

We skipped the machine research in lesson 9 as well as the experiments in lesson 15.

Summer Science - AIG Heat and Energy Units 5 and 6

I respectfully ask that you not pin pictures of my children to Pinterest. Thank you!

For unit 5, we learned about waves and sound by
making waves with a rope,

seeing sound waves (courtesy of the awesome bass in our van and the group Home Free),

observing transverse and longitudinal waves, testing objects to see if they reflect or absorb sound, measuring the speed of sound, experimenting with pitch

amplifying sound by making our own stethoscope,

studying waves and interference in waves. We skipped creating our own Doppler and other sound effects, lesson 27, and the special feature on J.S. Bach.

In unit 6, we learned about light. We skipped the blue experiments in lesson 28 but we did experiment with shadows, split light into its rainbow of colors, combined light by spinning our color wheels on a pencil.

We experimented with various materials to see which was most reflective,

  

showed how the angle of incidence is equal to the angle of reflection. This one works best with a laser pointer. A regular flashlight's beam isn't focused enough to make it work.

We observed refraction and how density affects refraction.
We skipped a few lessons in this section for sake of time. We didn't do lesson 31, lesson 33, and the projects for lesson 34.
