what is a good experiment on solids for a first grade class?

I assume that you're a teacher.  Try this...\n\nTake in some Cool Aid or fruit juice, a couple of ice trays, some tooth picks, and some plastic wrap.  Show the class that when it's warm, the juice is in liquid form.  Pour some juice into the ice trays, cover them with the plastic wrap, and stick a tooth pick in each cube hole.  Put them in the freezer overnight.  The next day show the class that the juice is no longer a liquid but is now a solid.  Then give each kid one of the popsicles you made.

Do an activity that allows students to drop objects in order to demonstrate the theories.

These are some ideas aimed for pre-k, 1st and 2nd grade:\n*you can provide different geometrical shapes and have them sort them according to color, size, shape, etc.\n*with the same shapes have them complete a pattern you start for them ex. red circle, yellow square, red circle, yellow square, etc.\n*try looking for a game called "Tangram", I don't know if you can buy one already done or you can make your own in this site:http://www.tangram.i-p.com/\n*give students play money and have them solve problems using it.

Here is a nice experiment to try.\nhttp://www.angelfire.com/mo/sasschool/DKScieMatter10.html\n\n"This tasty crystal making experiment is a great way to see the formation of crystals almost right in front of your eyes."\n\nAnother one.\nhttp://homeschooling.gomilpitas.com/explore/crystals.htm\n\n"Crystal Ornament"\n\nAnother.\nhttp://www.yesmag.bc.ca/projects/crystal_gardens.html\n\n"Crystal Gardens"\n\nOne for microscopic crystals.\nhttp://www.science.uwaterloo.ca/earth/waton/crystal.html\n\n"Crystal growing made easy"

any test that is given to a first grader would be challenging for a first grader, easy for a second grader and a peice of cake for a third grader..... what kind of test???

Since you need simple and portable, how about starting with something that uses light and prisms to create the spectrum? \nFrom there, you could go to show how rainbows are created ( where the light must be, what the sequence of the rainbow spectrum is) or compare how light colors mix compared to how m=paint colors mix.  I don't know if that is appropriate for the 10 th grade.  But working with light and prisms is always fun.\nmagnetism is always fun, too.

if u really want to get an answer to this question, u need to be more through when asking it. hello? i mean seriously, we dont know anything around the experiment you are working on. so take the noncharged part of the balloon and put it next to the cereal and paper. what do u think will happen. something will and if you did it then you would know.

Take various juices and put food coloring in them. Have some students taste the juices and see if they are fooled. Copy that down and make a chart for every juice and how many were fooled and not. It should be interesting. (I suggest water into purple to look like grape juice...and so on for others)

Are you asking for suggestions of things to bring in to show kids the difference?  If so, how about bringing the following dry things:\n\nCotton ball\nVery dry dirt\nFabric (wash cloth)\nSand\nBowl\n\nAnd then apply water to each of those items.  How does water change dirt, sand, a washcloth?  How is this different from what happens when you put water in a bowl?\n\nHope this helps in some way.

I'm a biology teacher, and a cell model is a project every year.\n\nUse a HARD beachball about the size of a basketball....or a cheap dimestore basket ball. Cut in in half and use thin wires to suspend the various organelles inside.

Use a big Tupperware container to put it all in. I did that for the 11 year old class and it worked just spiffy.

Science is the best way to find out about the world around us. Real science is not about learning facts, it is a way of thinking and a set of tools to explore and get close to the truth. \nScience is about observation, creative thinking and then very careful experimentation. Too many people come out of school thinking science is about learning dull facts - it is not!\n\nGet a packet of yeast and follow the instructions to start growing a teaspoon of yeast (add warm water and sugar). Don't tell the child anything about what yeast is or what it's for. Let them simply observe what happens over the next hour.\n \nDiscuss their observations in general terms and try to get them thinking critically about what is happening. Be led by their ideas - get them thinking! \n\nWhat is the sugar for? Why does the water need to be warm? Where are the bubbles coming from? Can you measure how many bubbles? Is the amount of sugar important? What if the water is boiling hot? What is yeast?\n\nWhen they start coming up with possible explanations, start them thinking about how they might test their ideas to see if they are true. Introduce the idea of testing just one idea at a time. \n\nStart designing an experiment with 2 or 3 pots. Introduce them to careful use of a themometer. One experiment might be to keep the quantitites of everything the same but just reduce the temperature of the water. Time how long the yeast takes to start growing. Can you measure how many bubbles (stretch a deflated ballon over the pot?).

I agree with flash cards, trivia, jeopardy, and maybe set standards for a wanted grade and aim for a prize.(chocolate or candy or gum works for the prize for me) Hope I helped!
