  It's almost Valentine's Day! When you teach teens, it can be hard to fight the candy and hormones.... so how about embracing the holiday instead of fighting it? I've compiled a list of Valentine themed activities you can do this year. MIDDLE SCHOOL IDEAS 1. Make borax crystal hearts! Borax and pipe cleaners are super cheap and students love watching the crystals grow. You can find directions on Steve Spangler's site here.  2. What is the most genuine present you can give your Valentine? Your own DNA of course! Do a DNA extraction of cheek cells, put the DNA into a microcentrifuge tube, and allow students to take their DNA home or give it to their Valentine. Need directions? Check here.  3. If you teach about plants, make some red and pink color changing flowers! This experiment takes a few days, but students enjoy coming in each day to watch the petals change color. You can find directions for this lab here. A few tips: Don't spend a lot of money- look for discounted carnations that are a week old. Also, I've found that leaving the flowers out of water overnight so the stems are nice and dry helps, because when you put them in the colored water they will be nice and thirsty and absorb the water faster.  HIGH SCHOOL IDEAS 4. If you are teaching genetics, this speed dating activity is a blast! I put up lights around my classroom and moved the desks in long rows so students face each other. Each student gets assigned a different monster and they rotate around the room on different dates, completing punnett squares with each date. At the end of the 3 dates they pick a monster they would like to go on a second date with. Its a valentine's day they won't forget! You can find the lesson here.  5. If you teach biology and classification, have students create a dichotomous key using candy hearts. They can classify traits such as color or number of letters on each heart. They are really inexpensive to buy and students can eat them at the end!  6. Your students are probably a little young to have match.com accounts, but they are still familiar with dating websites. In this activity, have students create a dating profile for a famous scientist. They come up with some creative ideas! You can find the lesson here.  7. Check out this "Vanishing Valentine" activity from Flinn Scientific. It is a great demo if you have covered oxidation-reduction reactions.  8. No matter which grade you teach, these anatomy valentines from Gnature with Gnat are adorable! They have phrases like "I want tibia your valentine" and "urine my heart." Tape a piece of candy on them and your students will definitely feel loved. You can download them for free in her TpT store by clicking here. I hope you and your students have a fun day!

 Halloween is coming up, and it is always a fun time to do some science experiments. I always try and find an experiment that fits my content area and ensures students are learning a concept they would have to learn in my class anyway. For example, elephant toothpaste in a jack-o-lantern is fun, but it doesn't have anything to do with biology, so it's a pass for me. (Yes, I'm a bit of a party pooper). However, I've come up with a list of ideas you can do for each content area, so hopefully you can find an experiment that is both engaging, AND tied to your curriculum!  If you teach BIOLOGY This idea is for my fellow biology teacher friends! It seems like every year the day after Halloween all you do is hear rustling of candy wrappers begin opened during class. It's a battle I've stopped trying to fight. Instead of saying "put away the candy," tell them to get it out! Have students pull out their candy, lay it on their desks, and classify it and make a cladogram. You will have some students that don't bring in candy, so I bring in my leftover candy from home. It's a win-win: students get to learn while eating candy, and I don't eat all the leftovers and save myself some time at the gym!  If you teach ASTRONOMY Glow sticks are readily available at the stores around halloween and are great for demonstrating chemical reactions. They are also great for teaching the concept that hotter and larger stars shine the brightest. Give students 3 glow sticks, have them place one in a beaker of ice water, one in a beaker of room temperature water, and one in a beaker of hot water. Have them compare the luminosity of the 3 glow sticks over a span of 10-15 minutes.  If you teach CHEMISTRY One of the best parts of teaching chemistry is getting to play with dry ice! In this lab activity, students explore phase changes and sublimation while comparing the change in mass of dry ice in water vs. regular ice in water. I have students use triple beam balances instead of electronic scales because it is good practice for them to adjust the hanging masses and practice their measurement skills.  If you teach FORENSICS Analyzing blood spatter is always an easy way to keep students engaged! Check out this quick and easy lab from the science spot where students learn about blood spatter patterns. If you teach PHYSICS This activity is always fun and a great way to discuss forces! All you need is a pumpkin and some rubber bands (okay.... a lot of rubber bands). Ask students if you think it is possible for rubber bands to make a pumpkin explode. After discussion of how it could be done, take the students outside and have them start putting rubber bands around the center of the pumpkin. (Tip: be sure to buy a medium sized pumpkin- too small and it won't work and too big the rubber bands won't fit). Continue adding rubber bands until it explodes! If students are helping add the rubber bands, I would advise having them wear goggles.  Lastly, if you just want to re-enforce some scientific method skills (observation and inference, CER, and graphing), check out these fun Halloween themed worksheets!
I hope you have a Spook-tacular Science Halloween! 
Earth Day will be here April 22nd and I'd love to send you some prizes for you and your students! Not one but THREE winners will be picked to win these amazing prizes!

The fine print:
 It's almost April Fool's Day and time to start thinking about how to trick your students! While it may be funny to scare students with a pop quiz or sending your best student to the principal's office, I like an April Fool's joke where the students learn a science concept at the same time. Check out these ideas on how to trick your students into learning a science concept: 1. "What's Wrong With The School Water?!" For this one, fill a clear drinking glass with with rubbing alcohol and set it up front. When you are ready to start class or students are working on bell work, bring out a few ice cubes and drop them in your "water." (The ice cubes will sink instead of float because the ice is more dense than the rubbing alcohol). Start yelling to the class "Something is wrong with the school water! Look at my ice cubes!" and see their reactions. Follow up with a discussion about density. (This video below from my friend James shows how it works).  2. Make a Stink Bomb Use this home made stink bomb recipe to gross out your students! Pretend that someone in your class keeps passing gas and make a scene asking them to stop. Once you tell them it's a joke, follow up with a discussion about sulfur and other things that contain sulfur (eggs). 3. "Do Not Open Bottle" from Steve Spangler This is a fun prank that your curious students won't be able to resist! 4. Dihydrogen Monoxide Tell your students that there is a new drug going around that they need to be aware of called Dihydrogen Monoxide. (Dihydrogen Monoxide is the chemical name for water). Show them this video clip and then ask the students what chemicals you think people might make this drug out of.  5. Rat Skulls Do you have students who try and eat in class even when you tell them to put the hot cheetos away? Do you have any small skulls left over from your last owl pellet dissection? Tell the students that you were cleaning the room yesterday and you found the skull in one of the cabinets. Explain to them that the only reason rats come to the classroom is because they are finding food. You can have a discussion about food chains (and if you truly want them to stop eating snacks, don't tell them the truth!) 6. Burning Money Tell the students that you had $5 stolen out of your wallet the day before. Tell them you know $5 isn't a lot, but you are really disappointed in them. To prove your point that it isn't about the money, take out a $5 bill and light it on fire yelling "see, it's not about the money!" (To light the money on fire without damaging the bill, dip the money in a water and rubbing alcohol mixture behind your desk where the students can't see).  7. Fools Gold Have a piece of pyrite laying around? (If not, check with your earth science teacher). Tell the students that you were hiking after school the previous day and came across a large piece of gold. Pull out the pyrite, tell them it is worth thousands, and today will be your last day because you are retiring. April Fool's Gold!  8. Set up a Fake Text
Head over to a website such as http://iphonefaketext.com/ and create your own fake text message conversation. The possibilities here are endless! You can pretend to have seen a conversation between two students or between teacher and student (see pictured). Kids are addicted to their phones, so might as well stoop to their level! I hope you have a fun day fooling your students! Enjoy! Becca |
