Science Ideas for 4/1/2016

There are many things I can’t believe, and one of them is that it’s April already.  We’re entering the crunch time of year – testing is either knocking on the door, or upon us already.  So upper grades, we have you finishing your last units in the next two weeks.  Lower grades, we’ve got you paced out a little further.  I hope you find the ideas below useful.

Kindergarten Ideas: We’re on to the first standard in your core, about the nature of science, and conducting investigations.  .  I’ll quote Objective 1 here: “Generating Evidence: Using the processes of scientific investigation (i.e. framing questions, designing investigations, conducting investigations, collecting data, drawing conclusions)”
This is a great one for rolling things down ramps.  We use the ramp thing a lot, but it’s just really easy to put together investigations, and kids like rolling things. For starters, compare two different types of balls, and see which one goes further when rolled down the ramp, across the carpet.  Have the kids predict, then talk about data, and what data you can collect to prove which one went further.  From there, you can do a lot of things to elaborate – change the ramp height, find balls of similar size but different weight, compare different surfaces (roll down the hall, or across tile.)  The idea is we’re trying to get them to think scientifically about learning something about the world.

Ramps are like soy.  Useful for so many things!

First Grade Ideas: Next week is a great week to go outside in the morning and find the moon.  Even if you’ve done that already this year, actually, especially if you’ve done that already this year, go check it out.  Observe those patterns.  Is it in a different place in the sky, compared to earlier this year? Look back to our soda straw moon spotting rig from earlier this year.  Check out my blog post about that from back in December: http://mrqsciencenews.blogspot.com/2015/12/science-ideas-for-12715.html




Second Grade Ideas: Observe falling objects and identify things that prevent them from reaching the ground. “ Design parachutes.  Find a nice high place to drop stuff – second story railings work great.  A small stuffed animal works well as a payload, and adds a little drama to the action. Use a stopwatch to time how long it takes to hit the ground, and refine the designs as they go! Doesn’t get much better than that!

 


Third Grade Ideas: Here’s something a little different for your forces and motion.  It applies to this indicator: “Show how these concepts apply to various activities (e.g., batting a ball, kicking a ball, hitting a golf ball with a golf club) in terms of force, motion, speed, direction, and distance (e.g. slow, fast, hit hard, hit soft). “ Though it’s really more of an engineering challenge.  They are called Stomp Rockets, and they’re really simple.  There is a 2 liter bottle, which is attached to a PVC pipe.  The pipe angles up, and you slide a paper “rocket” over the other end.  Stomp on the soda bottle to push the air out of the tube, thus launching the rocket, like blowing into a soda straw with the wrapper still on it.  See the picture below, it makes way more sense. So you start with the most basic design, which is just a tube, and the kids engineer it from there.  Add tail fins, weight, use different types of paper – the sky’s the limit!  I have three stomp rocket launchers built, though it’s best if you bring your own soda bottles.  The bottles do wear out after enough stomps.  The kids can measure either how far the rocket flew to gauge its success.  So this kinda teaches forces, but it’s really an awesome way to teach data collection, independent variables, and testing one variable at a time. 

A word about that – methodically changing one variable at a time is NOT a natural process for most kids.  It must be taught.  Don’t be afraid to go through this activity 2 or 3 times, really taking the time to talk about variables.  It’s complex! Take the time it deserves. P.S. – any grade level can do this, not just 3rd.  Just let me know, and we’ll make it happen!  It’s a blast.



Fourth Grade Ideas: Here’s an indicator from all the water cycle stuff: “Describe how the water cycle relates to the water supply in your community. “ I just received a few cool maps from the Public Utility Department at the city here – one of them shows our watershed, and I’ve attached it to this email.  A few things to notice about this map: which direction is the water flowing?  Look at the elevation numbers – what do those tell us about where water is going?  Does the Jordan River flow North, or South?  How do you know?  What do you think the dotted lines mean when the rivers hit the urban environments? Like any map, or good data set, there are so many questions you can ask, and so many things you can learn with your kids by examining it.  If you like this one, I have access to more.  Just let me know.


This is a random picture a watershed.  What you want is the attached file of the actual map I talked about above.

Fifth Grade Ideas: Still working with heredity.  Here’s a lesson from UEN that covers many indicators within the heredity standard: http://www.uen.org/Lessonplan/preview?LPid=2713  It’s all about mealworms and earthworms, which are delightful little creatures!  Let me know if you need any assistance getting your hands on some.  Sometimes the hardest part can be just getting out to the store to get a simple thing.  It’s as easy as “Hey Kevin, can you get me some worms for next week?”  I’m better than Amazon Prime. Just let me know.




Sixth Grade Ideas:  Here’s a little one for you: in trying to distinguish radiation from conduction and convection, show the kids that we can bounce radiation off a mirror.  Check out a heater like this:  http://www.murdochs.com/shop/comfort-zone-oscillating-parabolic-dish-radiant-heater/ The heating element is in the center, and the radiation bounces off the parabolic mirror dish in the back, thus spreading it out to the area we’re trying to heat.  If I had one to loan, that would be 1,000 times better, but we can still learn something from thinking about it.  That will help them understand that conduction and convection are when the molecules bump into each other, but radiation is a totally different mechanism.
