Photosynthesis Worksheets

This week  we spent a few days talking about photosynthesis.  We covered the basic differences between plant and animal cells last week and I wanted to briefly talk about the process of photosynthesis before moving on to our Human Body unit. Some of the things we talked about included as we learned about the process of photosynthesis: parts of the plant, plant cells and the plant organelles, what is needed for...

States of Matter: Solid, Liquid, Gas — Learning Activities

Are you working on chemistry this year? I thought I’d share some of the activities we did when we learned about the States of Matter. I also link to a number of other posts from our chemistry unit. We’ve been having a blast with chemistry — well not literally, but sure have been learning a lot! Today we did most of the hands on activities suggested by the wonderful, wonderful...

Explosion of Colors in Milk Experiment and Other Chemistry Fun!

Isn’t this pretty? This was one of our experiments as we finished up our chemistry unit! One of the chapters in our chemistry book (Real Science 4 Kids-pre-level 1) talked about mixtures. It talked first about how how some mixtures dissolve (like salt in water). Then it went on to talk about soap and soap molecules. We read how soap makes things like butter and grease “dissolve” in water. Detergent...

More Fun Science Experiments: Watch them Bubble, Bubble Bombs… Acid-Base Reactions

Our chemistry textbook also talked about acid-base reactions.  It explained how antacids can help neutralize the strong acids in your stomach. We contrasted this slow reaction…   to the more impressive reaction of baking soda and vinegar! DD was putting her fingers in to see how her stomach would feel. If you haven’t already done Bubble Bombs with your kids, be sure to do that as well! You take a...

Science Experiments: Red Cabbage Indicator (Fun for Ages 4 and Up!)

  We did a lot of Montessori science when the older kids were little, so this is an experiment we did years ago. Now the older kids are studying chemistry and ED is the perfect age (4) to enjoy the action of this experiment. Using red cabbage juice as the indicator, you add various household ingredients and compare it to an acid-base chart to see where that particular item falls...

Building Molecules Chemistry Activity

We moved on from talking about atoms to talking about molecules and chemical bonds. Since my kids are pretty young, this is just a basic introduction to how bonds are formed and made. Building Molecules Worksheet: This is a free download. The screen shot below shows 2 of 3 pages. We spent several days building different kinds of molecules: On the first day we built water, oxygen, hydrogen and hydrogen...

Science Experiments: Water Molecule Attraction

Matter is made of tiny particles that are attracted to one another. We did a series of experiments activities from Middle School Chemistry (the free, downloadable chemistry course) that show that water molecules are, indeed attracted to one another. We first used a medicine dropper to see how much water we could push out of the syringe. We also examined the pictures of the droplets we managed to photograph in...

Chemistry: Molecule Movement Experiment and Chemistry Review Worksheet

We’ve been covering the states of matter, atoms and molecules in chemistry. I wanted review some of the information we’ve covered and made some basic worksheets for the kids. First, we went over the three states of matter and looked closely again at the parts of an atom. Molecule Movement Experiment: Then we did a simple experiment with water to show that water molecules can move at different rates. We...

Chemistry Unit: The Size of Atoms

We started our chemistry unit a couple weeks ago.  We’re doing lots of reading and really enjoying the books in the NOEO curriculum. We loved, What’s Smaller Than a Pygmy Shrew?  (affiliate link)  It takes a look at protozoa, bacterium, molecules and atoms — even talking about electrons, protons and neutrons. After we read through the book the kids drew pictures of protozoa. (LD’s picture is on the left, DD’s is...
