## Forest Biome (Woodland Animal Habitat)

————– Here’s what we did today with our forest biome study: 1) We sang the continent song and the kids placed the continents in the world map (the world pin map is at the top right almost out of the picture). 2) We talked about the fact that different places in the world have different temperatures and different climates (ie. different biomes). We talked about our own climate (a desert)...

## Deciduous Forest — Diaorama Project

This week we’re going to make a diaorama on thedeciduous forest and its animal inhabitants. First wemade deciduous trees. The kids used cut up tissue paperand placed the bits onto contact paper. Then we putgreen paper onto the contact paper and cut out a treeshape. We’ll add a tree trunk later. Our other project today was to make coffee groundsquirrels. The kids decided to use colored sand for thesmaller version...

## Squirrel Math Grid Game

DD and I played a squirrel math grid game today. We took turns rolling the dice and gathering acorns for our squirrels. She also quickly did the oak tree life cycle. Both activities were from Prekinders.com (the acorns were from another game I printed out that we’ll play tomorrow, but if you have real acorns nearby that’d certainly be a better option!)

## Science Center Monday: Making a Periscope

My son really enjoys spy gear. Making a periscope (whichhe immediately started calling a “spy scope”) was rightup his alley!! Today’s science experiment was very simple and took lessthan 15 minutes. We took a long tubular box, cut a flap onopposite sides and opposite ends of the box, glued a smallmirror to the flap and taped it the flap on the inside of thebox at a 45 degree angle (make...

## Science Experiments — Repeating Activities

I wanted the kids to be able to repeat experiments theywere especially interested in. As we’ve done eachexperiment, I’ve written the steps out on index cardsfor LD to follow. After we’ve done the experiment I’veprinted photos of the experiments on card stock andplaced them on a key ring. LD can flip through the stackand choose experiments to repeat (and I have them onfile and easy to access in the coming...

## Woodland Animals — free three part cards

We’re going to be starting our new unit on biomes/animal habitats and will be learning about forests this next week.  It just so happens that there are some beautiful 3-part Montessori cards free for a few days at the Montessori Print Shop that will work in nicely with our studies.   I can’t post a picture today of these lovely woodland animal cards, but animals include the skunk, bear, deer, rabbit...

## Check out the Giant Crystal Caves

The picture above is a rock called Gypsum. When wewere in Coober Pedy (known for its opal mining), we wentnoodling (looking around the piles of dirt brought outfrom the mines) for opal. We didn’t find much opal, butwe did find some beautiful crystal rocks called gypsum.It breaks easily into fine, needle-like strands. Please like & share:

## The biggest crystals in the world

I’ve included a picture with ED’s tiny hand. Now want to see something astounding? Check out this website: http://www.ironammonite.com/2009/12/surviving-cueva-de-los-cristales-giant.html In a cave in Mexico where the temperatures soar to 50 Celsius/122 Fahrenheit, there are gypsum crystals that make a grown man look like ED’s small fingernails! You can also check out the National Geographic website: http://ngm.nationalgeographic.com/2008/11/crystal-giants/crystals-photography I found even the story of how they entered the cave (without perishing) and...

## Science Experiment: Transparent, Translucent or Opaque

I gathered a number of items from around the houseand put them all into a ziploc bag with a flashlight. Thenbefore letting the kids sort, I made sure they saw examplesand understood the difference between something thatwas transparent: you can see obects clearly through and light passes throughtranslucent: you cannot clearly see objects, but light passes throughopaque: light does not pass through I was surprised by a number of objects...

## Food Groups Sorting

This activity would be easy to create by clippingfood items from an advertisement. I got mine on saleat some point. There’s also a free file folder game athttp://filefolderfun.com/FirstGradeHealth.htmlwhere kids can sort items into grains, fruit, vegies,milk and meat. Anyway, here is DD sorting foods into the variousfood groups. PS — When I was talking to my hubby about the“food pyramid” he said, “Oh no, that’s outdated.”  HappilyI could say that...

## Science Center Monday — Sink or Float Activities

I have lots of science experiments that we didn’tget to this past month. Since we’re going on toother units, I didn’t want to do science experimentsdaily. Instead, I have decided to set up a new sciencecenter every Monday. That gives me time over theweekend to gather the materials I need and to getthings set up. On Thursdays, I plan to set up an “old” experimentthat we’ve done already out on...

## Sink or Float Experiment Activities (cont.)

Part III: Float a Penny Test how many pennies can be placed on an index cardbefore it sinks. Do the same with a popsicle stick. See how many rocks/pennies can be placed on a pieceof bark before it sinks or tips over. Part IV: Float AND SinkTry to make the following items float. Then try to makethat same object sink. Do not place anything on it. Try: aluminium foilclaya plastic...

## Camouflage Animals

The kids did this quick camouflage activity (from Take itTo Your Seat Science Centers, Grade 1-2). We alsodid an online game trying to find the camouflaged animals.Find the frog, ibex, snakes, fox, insects, turtles and more.The kids played that for a little bit, but we also just enjoyedlooking at images on the computer such as this websiteabout animals that change colors:http://webecoist.com/2009/02/22/color-changing-strange-animals-species/ Please like & share:

## Experiment 13: Red Cabbage pH Indicator, Acid-Base Tests

This month we’re doing lots of science experiments. We also have a friend with us for the remainder of the school holidays (end of January for public school kids), so the kids have been having long, imaginative play sessions most days. It doesn’t leave me with too much more to talk about on the home-schooling front. Life in general though is full to overflowing! Isn’t that the case for most...
