If your summer plans, like ours, include going to the ocean, you may be interested in this video from Reactions about how seashells are made. In How Seashells Are Made viewers learn that seashells are made of 95% calcium carbonate and 5% protein and sugar. The video doesn't stop with just listing the components of seashells. By watching the video viewers can learn how calcite and aragonite are layered in seashells to create a hard shell.

I've never been a "lay on the beach" kind of person. I'm the person you'll find wandering and looking at neat things that get washed up on shore. My daughters are the same way. If you have students that like to wander and collect seashells, use that curiosity as a segue into a science lesson about how seashells are made. This video is a great candidate for inclusion in an EDpuzzle lesson in which you add questions and your own clarifying remarks for students. Watch my EDpuzzle tutorial to learn how to add questions to an existing video.
Google Sites can be a great platform for students to use to maintain digital portfolios. In fact, I did that last year with my computer science principles students. The challenge for a teacher when students use Google Sites for portfolios is keeping track of updates to those portfolios.
The method that I came up with to keep track of updates that students made to their Google Sites was to create a weekly update assignment in Google Classroom. Then every week students added a new page to their sites. They then had to respond to the assignment with a link to the new pages they made in their Google Sites.
In this short video I demonstrate how to keep track of updates to students' Google Sites by using Google Classroom assignments. The video shows a teacher's perspective and it shows a student's perspective of this method.

Independence Day here in the United States is ten days away. Nothing says, "Happy Fourth of July" like a fireworks display. Watching Fourth of July fireworks displays is a quintessential part of the American experience in the summer. This year my daughters are just about old enough to stay up late enough to watch the fireworks with me, we're at least going to try.
If your kids are old enough to watch a fireworks display, they might have questions about how fireworks work. I know that my oldest daughter will definitely be curious about how they work. To refresh my memory I'm rewatching the following videos from NPR's SkunkBear, National Geographic, and Reactions to learn about the science of fireworks.
Summer is here in the northern hemisphere. It's a great time to go outside and soak up some sunshine. A little vitamin D is good for everybody. This is also a time when many schools run summer enrichment programs that provide kids with some learning activities that might not otherwise happen during the school year. For example, taking kids outside for science lessons. To that end, SciShow Kids has four suggestions for outdoor science lessons. In Fun Summer Science adults and children can learn about the science of bubbles, kites, ice cream, and solar energy. Each segment includes an explanation of the science and brief suggestions and directions for a hands-on activity.
Earlier this year SciShow Kids released a video about building a solar oven. As you might expect, the video explains the science of using solar energy and explains the basics of how to build a solar oven. However, the video isn't quite detailed enough to be the only source that you or your students consult when building a solar oven. Fortunately, NASA, the US Department of Energy, and the Lawrence Hall of Science all offer detailed directions.
NASA provides two sets of detailed, written directions for building solar ovens. This set of directions (link opens a PDF) was created for students in 7th through 9th grade. This set of directions (link opens a PDF) for building a solar oven was written for 6th through 8th grade students and culminates with students attempting to make s'mores with their ovens.
Cooking With 'Sol (link opens a PDF) was published by the US Department of Energy. It was written for students in 5th through 8th grade to follow directions to create a solar oven.
DIY Sun Science is a free iPad app from The Lawrence Hall of Science. The app features directions for hands-on lessons about the sun. The lessons are a mix of activities that students can do on their own and activities that they should do with adult supervision. All of the activities use common household goods. Some of the activities that you will find in DIY Sun Science are measuring the sun, making UV detectors, detecting solar storms, and cooking with a solar oven.

Earlier this week I answered an email from a reader who was looking for a way to share his Google Slides with his students without them being able to see his speaker notes. Unfortunately, there isn't an add-on or extension that will do that for you. Instead you have to make a copy of your original slides then remove your speaker notes from the copy before sharing or publishing it. How that is done is outlined in this short video.

I often give search challenges to students in the form of visual prompts and written prompts displayed on slides. I keep some notes for myself in the speaker notes section. The slides that I give to kids don't have my speaker notes so that they don't have any extra hints unless I choose to give them.
