What are some good science related activities for a five year old with ADHD?

I am going to be a nanny for a child with ADHD this summer and he is really into science. I am trying to find an activity that will keep him entertained but also something that will keep his attention. Also, if there are any nannies with experience with ADHD children, I am open for any advice!

Why do people believe Autism is related to immunizations?

Would to like to hear oppinions on why some people believe Austim is related to routine childhood vaccinations. I have identical twin boys who have had the same vaccines in the same enviroment, and have ate the same foods (bc I have heard also there is a theory about chemicals used to preserve food contributing to Autism). The first born twin has high-fuctioning Asperger’s Syndrome, and the second born does not have any form of Autism. Based on this experience I don’t believe Vaccines had anything to do with this. If I had to venture a guess for the cause I would say that it may be an area of his brain did not develop correctly. Anyway, would love to hear oppinions on this subject, what you believe might be a cause of Autism, or other reasons why you may choose to not vaccinate your child. Thanks.
Would like to add that they were tested, and confirmed as being identical. Also that they were born at 29wks premature, and were on the same devolpment level at birth, and through their stay at the NICU.

Mom Refuses Ritalin and Heals Her ADHD Autism Kids With Natural Medicine

www.thenaturalguide.com – (Video by Larry Cook) Deborah Merlin raised prematurely born twin sons diagnosed with a host of medical problems and neurological challenges. She refused to put her children on Ritalin or other stimulant medications while at the same time the other conventional medicine treatments and therapies she tried resulted in multiple failures. After seven years of determined research she finally found success with dietary change, supplements and natural medicine therapies prescribed by an integrative medical doctor. Her integrative medical doctor ordered an amino acid panel and found that one of her sons was deficient in several amino acids. Amino acids are the building blocks of neurotransmitters in the brain. Shortly after her son started on the amino acid supplements, his facial tics stopped, his violent behavior went away, his seizures disappeared, he became happier, and remarkably, he went from failing in school to getting A’s and B’s in school. Watch the video to hear the whole story, and then order her book, “VICTORY OVER ADHD a holistic approach for helping children with Attention Deficit Hyperactivity Disorder” from www.amazon.com or her website http Video Interview of: Deborah Reinauer Merlin www.victoryoveradhd.com Produced by Larry Cook Author of The Beginner’s Guide to Natural Living www.thenaturalguide.com
