My Science Box

 

Age Range: 5-22 (Grades 1-College, children with parental supervision)

 

This website developed by a California Science Teacher provides free access to hands-on, classroom tested, science lessons for a wide grade range.
The site uses the concept of a virtual “teaching box” to organize the activities and lessons. In a classroom environment, a “teaching box” is a cardboard box that contains an assortment of materials, lesson plans, resources, and assessments for teaching a particular topic. The virtual teaching boxes at My Science Box are designed to provide you with everything you need to teach a unit of science in areas such as:
* Biology/Life Science
* Cell Biology
* Chemistry
* Earth Science
* Ecology
* Genetics
* Geology
* Human Biology
* Physics
* Technology and Engineering

When you get to the site, you’ll see a brief introduction. Use the menu on the left to review the lessons offered by grade level including K-2, 3-5, 6-8, 9-12, and college. Or explore the lessons by scientific concept (as described above). The lessons are also sorted by:

* Classroom Activity
* Labs and Projects
* Curriculum Unit
* Field Trip (for destinations in San Francisco Bay Area)
* Computer Activity

Most of these lessons and activities can be tweaked for use at home or by a homeschool support group or co-op class.

You can also simply click on the horizontal menu at the top of the page to access “Curriculum Boxes” that offer lessons and activities for MIDDLE SCHOOL students in grades 6-8 on:
*Ecology – Habitats, ecosystems and population change
*Watersheds – Watersheds, wetlands, erosion and the San Francisco Bay
*Geology – Rock cycle, geologic time, and Earth history
*Genetics & Evolution – DNA, genes, evolution & adaptation
*Plate Tectonics – Sea floor spreading, volcanoes, and earthquakes
*Physiology – Cell biology, plants, animals, and the characteristics of life
Click on any box and a new page opens with a variety of lessons and activities to teach that particular topic.
Because the teacher who designed this site lives and works in California, the lessons are aligned with the Science Content Standards for California Public Schools. They are designed to “actively engage students in observing, experimenting, discovering, discussing, and building models during both ‘lecture’ and ‘lab’ sections.”
Almost every lesson can be printed out for use offline. Just click on the words “Printer-friendly version” at the bottom of each lesson page.

Spelling for Those with the “Spelling Gene”

Merriam Webster: Spell It!

Age Range: 6-16 (approximately, with parental supervision)

I’ve always maintained that some people are born with a “spelling gene.” Interestingly, current brain research supports the idea that some brains are hard-wired for spelling. They just “get it”. For that segment of the population, spelling is fun! It’s a joy! Words and their root forms and origins are fascinating.

For students of all ages who excel at spelling, this website (sponsored by the Scripps National Spelling Bee in cooperation with Merriam-Webster) offers free spelling exercises that are interesting and challenging. It’s a little slice of heaven for those with spelling in their DNA. When you get to the website, you’ll see a brief introduction and a menu titled “Words From” that include:

  • Latin  
  • Arabic
  • Asian Languages
  • French
  • Eponyms
  • German
  • Slavic Languages
  • Dutch
  • Old English
  • New World Languages
  • Japanese
  • Greek
  • Italian
  • Spanish

Click on any one and a new page opens with a brief explanation and a list of “Study Words.” Click on a “study word” and a new page opens in the Merriam-Webster Online Dictionary with audio pronunciations. You’ll find the word’s function (part of speech), etymology, definition, and synonyms.

Some words have a “dialog bubble” that contains a spelling tip for that word.  Click on “Challenge Words” to find an assortment of more difficult spelling words. Click  on “Now You Try” to participate in an interactive exercise to challenge your knowledge of words, parts of words, word roots, and knowledge of spelling rules and exceptions. Wordsmiths and spellers will gleefully spend hours here testing their skills. There is a function that allows you to print out the spelling words to practice offline too. 

Back on the home page, you’ll also see “Words You Need to Know.” As explained at the website, “These words appear frequently in student essays, and every writer should become familiar with them. You should also study these words to prepare for classroom bees.”

This site’s main purpose is to provide visitors with the official list of study words for the 2010 spelling bees. However, it stands alone as a terrific and challenging educational tool for those who love words and spelling.

Learn Genetics

Age Range: 10 and up (with parental supervision)

This website, developed by the University of Utah, provides free lessons, experiments, activities, virtual labs, and worksheets designed to provide a basic education in the science of genetics.

When you get to the site, you can get a good introduction to the topics of DNA, genes, protein synthesis, heredity, traits, and life on a cellular level by exploring the “Basics.”  You’ll also see some new features and below it a menu that includes:

*Genetic Technology – Learn about stem cells, gene therapy, cloning, and gene-targeting technology.

*Virtual Labs – Swab your cheek and extract DNA from your cells! Use gel electrophoresis to discover how scientists work with tiny molecules they can’t see.  Perform a DNA microarray experiement to compare a healthy cell and a cancer cell.

*Epigenetics – Find out how factors from the environment alter gene expression.

*The New Science of Addiction – Take a physiologic and molecular look at what causes drug addiction.

*Variation, Selection & Time – Discover what molecular genetics tells us about natural selection.

*Genetics & Health – Explore the “Genetic Disorders Llibrary,” examine your family health history, and find out how medical treatment can be custom-fit to your genome.

You can also learn about the ecology of Utah’s Great Salt Lake and explore an archive of fascinating presentations on RNA, finding a gene on the chromosome map, mutations and genetic disorders, biological warfare, and much more.

Be sure to click on “Teacher’s Resources” located in the top, right corner of the home page. It will open the “Teach Genetics” website where you’ll find additional tools and resources for learning about genetics, bioscience, and health. There are free classroom activities and take-home activities to teach heritable traits, and you’ll find an extensive “Print-And-Go Lesson Plan Index.”  While this is designed for classroom use, it can be tweaked for the homeschool environment.
