Homeschool Science: Year in Review and What’s Coming Up

When I think about all we’ve done this past year in 2015 in science, I’m really pretty amazed! It’s been a fun, full year!  This post has links to dozens of our science experiments, printables and hands-on activities. You’ll find direct links to the posts in the table below. We managed to squeeze in various engineering (STEM) type activities here and there. In January of 2015 we were in the...

Giveaway of Molecules to the MAX! — IMAX Film Newly Release onto DVD (Now Closed)

Just as we were finishing up our Chemistry Unit on the periodic table, the team at Rensselaer Polytechnic Institute got in touch with me to see if I would be interested in reviewing and/or hosting a giveaway of their  Giant Screen animated film, Molecules to the MAX! This film has just been released on DVD and Blu-Ray. I talked with the kids (and we watched the trailer www.moleculestothemax.com) and decided...

Chemistry Unit: The Periodic Table

This semester we did a new unit on chemistry and focused on the Periodic Table. We typically use secular resources, but I previewed Chemistry 101: An Overview of God’s Chemical World over the summer on the recommendation of a close friend. It is a wonderful resource. I found the video to be really well done (the kids really enjoyed it) and while there were a few references religion (especially in...

Chemistry Unit: Bohr Diagrams

The last topic in our chemistry unit has been about Bohr Diagrams.  We’ve been talking for the last week or so about the organization of the periodic table. Elements are organized by atomic number how many electrons are in the outer shell by which shell is their valence shell (or the shell that electrons are added to) Columns tell us how many atoms are in the outer shell. Rows tell...

Chemistry Experiments for Kids (Grade 2) – Mixtures, Chromatography, DNA Kit

Today, I want to share the three more chemistry activities we did during our unit on chemistry for my youngest, who is currently 7. Mixtures Un-Mixing: Chromatography DNA Kit Earlier this week, I shared the first two science experiments we did, and you can find those here (and in the free pdf printable at the bottom of this post): Matter is Neither Created Nor Destroyed (Molecules switch atoms) – Chapter...

Chemistry Experiments for Kids (Grade 2) – Matter is Neither Created Nor Destroyed — Acids and Bases

This semester we’ve been doing a Chemistry Unit for science. We tend to do our science and history units together. In the next two posts, I wanted to share some of the activities I did that were more geared toward my youngest (my older kids have done these before).  Then after that I will share the chemistry materials my older two (grades 5 and 7) have used as we’ve delved...

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 ziploc...

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...
