5 Best Start-of-the-School-Year Experiments

Great Science Experiments and Demonstrations

One of the fun things about being a science teacher is being able to do hands-on activities and fun demonstrations.  These are the things kids remember when they get home, and remember years later. We've all been at some type of picnic or family function and heard someone talking about their crazy, wacky science teacher and the demonstration they did in class. Its multi-sensory, and different than other classes, and therefore more memorable! 

What are some of your favorites? 

What do you think makes a good demonstration or a good hands-on activity?

Requirements for a good demonstration

In my opinion, these are some things to consider to make a successful demonstration

• It must use readily available materials. Materials that are too hard to get are unfamiliar to students and difficult for you to set up. It's also difficult to make up for students who might be absent 
• Must work reliably! You don't want an activity that only works some of the time, or even most of the time, you need to be pretty sure that it's going to work.
• It must clearly demonstrate the principle that you were trying to show. This should not be a leap for students to understand the science after they have done the initial activity or seen the demonstration. 
• Sometimes I do an activity as a demonstration because I want to talk about it as we're working, it would be difficult for students to carry out correctly, or because I'm limited on space and materials for students to do it on their own or any variety of other reasons including safety. If it is feasible for students to carry out themselves, that is preferable.

Here is another source on what makes a good demonstration

Here's a secret for you

As a science teacher, demonstrations are fun, but I don't really like doing them! I get nervous! It's too much like a stage performance. I'd much rather have students run through stations or do activities. But some activities still lend themselves well to demonstrations. 

My Favorite Demonstrations 

(with accompanying videos; which can be a back up plan if you really don't like doing demonstrations)

• Air pressure demonstration using a soda can 
• Coke and diet coke density demonstration
• A cloud in the bottle
• And many more here... and also 100 Fun Science Experiments / Science Fair Projects for Kids from Go Science Girls

STEM Projects

What about stem projects? What are some great stem projects to get your students thinking? Building and interacting? These can be great for the beginning or end of school or even for summer school, summer camps or those off days, such as those with assemblies. 

Stem projects and stem activities are such a broad category if you look them up you will find a wide variety of things. In my mind they break into at least two categories. Those that are chance for students to develop a hypothesis and test an experiment, and those that are a chance to build a product and work with a team to problem-solve and create something.  These may overlap, for example students may test something to make their product better.  However, students aren't really demonstrating the scientific process they're focused on working towards a goal.  This is more of an engineering project. 

• One of my favorites is soda can cars. Students can even recreate this at home if they want to pretty easily.  
• Another favorite is to see who's raft or boat can support the most pennies or paper clips.

• There is a common experiment, which is very engaging with milk, food coloring, and dish soap.  Just be aware of the potential for a lot of cleanup, or any milk allergies. 
• Static electricity activities can be easy, fun and engaging, such as bending water, and balloon races.  These are described in details here in my FREE STATIC LAB
• A balloon car or a CD hovercraft are also a lot of fun, and can be a chance for students to experiment and improve their design.  
• A solar oven can be a longer-term project where students can really experiment with the materials and the angle, or it can be done as a one time project. 
• More ideas are available here and here.  

Some of these can be a chance for students to experiment and develop an experiment, hypothesis, and a procedure. Others can be a great chance to explore a new topic or new concept at the beginning of a unit.  They are also great as a quick station or engagement activity, as well as a jumping-off point to get further into the unit.  In my opinion, they should be something that can be carried out in a period or two, unless you really want to start a much longer project.  Otherwise you risk losing the flow of what you are trying to teach. 

Lastly, another way to go is longer-term projects such as factors that affect seed or plant growth, longer-term monitoring of weather, composting (conditions that cause garbage to break down) or even setting up ecocolumns.  

For more information on these type of projects, I would just looking into Problem based learning (more to come on that).  A couple great sources of information are available here and here.

I'd love to see pictures of your science activities!  Please share with me on facebook, instagram or by email. 

Free Training: How to Be In Two Places at Once

A little summer professional development for you

We all like to learn something, especially if it's focused on making our lives easier and saving us some time during the school year.  I know we aren't thinking about school at the moment, but give it a chance....it's not so bad if you can sit in your living room, or on your deck, and learn some tips to make your life easier.

I want to focus on ways to limit your time at the copier, and also ways to save yourself time grading. This lets you be in two places at once because while your papers are being graded, you can be working with students, eating your lunch, or even at home enjoying your time with your family instead of grading. 

Limit your time at the copier, here are some easy tips

• If you are copying something like a reading, news article, or even directions, make a class set or make a class at +10.  If you're a secondary teacher and have 100 or 150 students they don't all need a copy.  Chances are many of them will get left on the tables or thrown out.  You can always make some extra if students want to annotate them, or keep them, but you will still end up with much few copies. Fewer copies = less time standing at the copier!  They will get trained pretty quickly that you're going to re-collect the directions or the reading.  If anyone really wants to keep it or has marked it up a lot that's fine, but it will save a lot of paper and a lot copying time and frustration.

• Secondly, try going digital! There are excellent resources on digital interactive notebooks.  Look into these, Google forms instead of quizzes, or start using Google Classroom.  All of these are amazing because you will no longer be spending your days standing in line at the copier, fighting with the stapler, or paper jams.  You simply make your assignments, assign it to your students and a copy is automatically made for each one of them it's a huge time saver!!!  Also, if they need a new copy, that can be done painlessly.  It's automatically saved so they won't lose theirs either! A few good resources for going digital are 
• The Blended Classroom (Leah Cleary)
• Study All Knight
• Alice Keeler
• Shake Up Learning
• Thirdly think about how you can save some paper.  When you save paper you're also saving yourself time at the copier. For example can you copy something on a half sheet? I do bell work on a sheet for the whole week and make a box for each day. I have even done it for two weeks.  I collect the same paper every day for that time period. That means I'm only copying one bell work sheet once every two weeks or once every 4 weeks if I do them double-sided, rather than daily! 

Saving Time Grading

• A lot of assignments can be graded simply on a check/check plus/check minus/zero basis. It's pretty easy to see whether the students did the assignment, they did it almost perfectly, they did a really poor job on it, or they didn't do it at all. You can give some quick feedback, but this saves you a lot of time checking every single word on their paper.  Over time, if you have a lot of grades like I do, it will become pretty obvious all of those checks and check pluses and check minuses will average out.  I enter them in my grade book as 100, 75, 50, and 0.

• Let the computer grade automatically!  One of the best ways to do this is with a Google form quiz. You set up the quiz questions, and of course an answer key, ahead of time. It will automatically grade if they are objective questions. You can choose if students get immediate feedback or if their scores have to be 'released' by you.  

Bonus

• Another option, depending on what type of devices that you have, is Socrative. This is easier for students to do phone or some other smaller devices that Google forms, and it also can give immediate feedback and automatic grading.
• Lastly, I have never used Zipgrade, but I've heard amazing things about being able to grade objective questions on your phone.

What will you do with your free time, now that you are spending less of your planning period, lunch period, and after school time grading papers and standing at the copier?
