In science we have been learning about our body. We made skeletons yesterday and today, we learned about the organs inside our body. Here is Cassie modeling our “organ apron” while we put her organs on 🙂

Force and Motion
This week we have been learning about force and motion.
We can push objects.
We can pull objects.
Objects can move fast.
Objects can move slow.
Exploring simple machines
Liquids and gases around KES
To wrap up our unit on states of matter, we went on a search through our school for liquids and gases. Here are some of the things we found!
States of matter
This week we are learning about states of matter. Early in the week we explored ways to change paper by tearing, folding, cutting, coloring, and crumpling it. Then we learned that *some* solids can be melted and turn into liquids – and that some liquids can be frozen and turned into solids!! We did an online activity freezing and melting different items then we tried it in real life!
First we started with solid popsicles, put them in the microwave for 40 seconds and watched as they melted. When we took them out, they were liquid!!
Then we took apple juice (liquid) and poured it into popsicle trays. After freezing them overnight, the apple juice turned into a solid popsicle!!
Star Lab
Today we went to the star lab (an inflatable planeterium) and saw stars, the moon and constellations!
It was a little scary when we had to crawl through the dark tunnel but once we saw the stars and pictures, it was awesome!
Properties of Matter
Last week we learned about properties of matter. Here are some photos of a few of the activities we did.
We also tested the density of some items (density is one of the properties of matter!) Items that are very dense sink, items that aren’t very dense float.
More about sounds
Friday we made a video recapping all that we had learned about sounds this week. We know that sounds are caused by *vibrations* – we made tuning forks vibrate and felt some toys vibrate as well. We made loud and quiet sounds, high-pitched and low-pitched sounds, and we explored how to make sounds by shaking and hitting different instruments. We had so much fun!!
Sound
This week we have been learning about sound – loud and quiet sounds, high and low pitched sounds, and how we can make sounds (by hitting or shaking instruments, for example). On Monday we learned that sound waves are caused by *vibrations* and then we did an experiment from our science book to show how sound waves move (they move up/down and back/forth).
Light
This week we learned about and explored light. We learned about light and dark, sources of light, and saw light absorbed and reflected. We also used a prism to see the colors of light (there are seven!) and painted a rainbow with those seven colors.
