If you're Jewish or Christian there are a lot of ways to incorporate Bible time into it as well. Studying the scriptures on creation and all the animals. Particular emphasis on the 'fire breathing' creatures and the microevolution of animals still in existance like alligators and lizards.
I'm doing the solar system with my 2nd and 4th grader right now- The Magic School Bus videos and books are great- our local library has a large supply of them. We are doing some Bill Nye videos too, but not sure if those would work well for your age group. Other then that we are reading a Magic Tree House book called Midnight on the Moon together, we read about Niel Armstorng, and here are a few links I have pulled things from:
We did a solar system unit last year. We made cookies (got the idea from Home Education magazine July-August 2010 'Cosmic Cuisine' article - our library has this magazine) for each planet, decorated them to look like the planet (we even did tiny cookie moons). The article tells you approximately how big to make each cookie so they are roughly to scale with each other. We talked about how big the sun would be if we made it (we did not - it'd be huge!).
we always write a poem for each planet and the dinosaurs
not sure if this has been wrote! but we hand our planets made out of cardboard, the kids decorate and paint them to look just like the planets, and we make them very big, also we put black paper you get at the school supply store on the wall and put the plantets and stars(popular ones plus) on it,
also we have put the planets on the wall and put the facts by each planet
we read stories about each subject, fiction and non fiction
i have the kids write a story about how they were shipwrecked with the dinosaurs, drawing pictues, and turn them into books
we've done a few space ones also!
we keep note books of the solar system, and dinosaurs,
we also make large cardboard figures of the dinos and place them around on the walls, also putting up the trees and a volcano makes it feel like we are there!
we watch movies about dinos and solar system, visit omsi,
at night we sky watch, we have this neat free app that lets us see where the planets and stars are
we listen for anything on space on the news or search things out, we'd be doing some research on the meterite and astroids now!
theres more but i cant think of them right now! be back later!
I just found out about it yesterday and signed up. I have received a free mini lesson, but have yet to watch it.
My very small little city has a planetarium and often has free events. there is also a Paleontological and Mineral & Lapidary society that has free cool stuff all of the time plus they go on Sat morning adventures every now and then and digs up lil fossils.Depending on where you live, google and see what comes up!
I too would be interested in more dinosaur stuff though.
You could do both. Take half the week to start one and then the other half to start the other and work in the other subjects with each of the projects with more of the focus on the projects for the learning enjoyment. :)
