Sharing posts from 2015 year in review

January 1, 2016 by Lisa Grable 2 Comments

Reflecting on how far I've come with Casa Bouquet and share 2015 year in review, I'm sharing some of the top posts for 2015.

I began blogging in March 2015. For New Year’s, I thought it would be fun to reflect on how far I’ve come with Casa Bouquet and share 2015 year in review. I’m sharing some of the top posts for 2015. This has been a lot of hard work, but I am so happy and grateful for my readers and the community of bloggers.Reflecting on how far I've come with Casa Bouquet and share 2015 year in review, I'm sharing some of the top posts for 2015.

apple-battery11 fruit battery activities for kids was my first round up of science activities from the Internet. I added my own ideas for how to do inquiry with apple or lemon batteries, too!

 

 

 

 

arbonne-mascaraMy dear friend, Michelle, has guest-posted for me twice. Her 3 must-haves for beauty – Arbonne was a big hit. It’s fun to find out how to use products and how they actually work.

 

 

 

 

 

 

lulus-viewI just love Hawaii and it was so much fun to write 8 Oahu breakfast spots. The Gardener and I love to watch sunrise and start the day with some excellent local flavors.

 

 

 

 

6-self-help - 46 books for life transitions was my first Culture post about books. It was a challenge to write because the message in books is so personal to me. I enjoy sharing how these books have helped me.

Preparing for college at the end of high school includes planning, tips, and checklists. Entrance tests, applications, financial aid, and more!I loved working with middle and high school students to achieve the dream of college. 6 tips for preparing for college has my best advice for resources and steps children and families should take to work through the difficult maze of choosing and applying to college.

11 fruit battery activities for kids

September 4, 2015 by Lisa Grable 8 Comments

apple-battery

A fruit battery science experiment is fascinating for children while tackling electricity, a topic on the list of hard topics to teach. A fruit clock or homemade batteries using fruit juice or other liquids with electrolytes are fun and easy.11 fruit battery experiments use a chemical reaction and physics to teach energy, electricity, and battery science. Fruit clocks and voltaic piles included.

Safety note: Be sure to explain safety precautions to children. These experiments use acids and electricity. Eye protection should be used. Before and after this experiment, be sure to thoroughly clean hands. Disclaimer: All information provided on this site is for entertainment and education purposes only. Using any information from casabouquet.com is at your own risk.

The basic setup is two different metal electrodes inserted into a fruit. Use wire to connect the electrodes to a light, clock, or current-measuring device. OR make a voltaic pile by alternating discs of two metals with paper dividers and using fruit juice or another solution of electrolytes.  These 11 fruit battery experiments encourage children to ask questions about electricity, collect data, analyze, and share their findings.

When trying a fruit battery activity, I always encourage children to make it into an experiment. There are several areas where variables can be changed.

Electrodes: provide copper, zinc, carbon, aluminum, and even magnesium. Copper and zinc are the traditional electrodes for a fruit or acid battery. Provide different thicknesses of these metals. You can also mark the metals at 1 cm intervals with a permanent marker so the children can measure the result as the electrodes are pushed into the fruit farther and farther. You can also use discs such as pennies, nickels, quarters, washers, or zinc disks pushed out of a galvanized electrical box. For a voltaic pile, you can use card stock, brown paper towels, or coffee filters for the separators.

Electrolyte: For fruit, try lemons, apples, and potatoes. Other citrus fruits will work, the children may find a difference between different types of apples (Gala vs. Honey Crisp?), and some have gotten carrots to work. You can also try different liquids such as Diet Coke, orange juice, sports drink, vinegar, and baking soda or salt dissolved in water. Use pH paper or a sensor to add measurement of pH to the experiment.

Measuring current: a favorite of my students is to light up an LED clock with the battery. You can also provide red and green LED lights or a bulb with wires cut from a fairy light string. A microammeter gives the ability to measure the actual current being produced.fruit battery activities

What is the science?

Content: electricity, direct current, batteries, electric circuits, energy transfer, voltaic pile

A battery often has two conducting metals, the electrodes, and a solution with charged ions that can move, the electrolyte. The electrode called the cathode (positive, +) receives electrons, while the anode gives up electrons (negative, -). The electrical current is measured in amperes (or amps). This can be thought of as the number of electrons that pass through a point per second. The short leg of an LED light is the negative, and should be attached to the negative side of the battery. The long leg is positive, and should be attached to the copper side of your battery.

Let’s talk story

apple-batteryThe apple battery was one of my middle schoolers favorite energy activities. It was exciting to see how long a clock would run off the juice of one apple. Most children had not had experiences with electricity. It was fun to work with batteries, wires, and bulbs to get the basics of electric circuits.
