1st Grade

Food Systems

How does the food we throw away affect our community, and how can we waste less food?

Students explore the impact of food waste on our communities, focusing on how students can take action to reduce food waste. Students investigate why food is thrown away, how they can reduce the amount of food disposed of, and ensure that food waste is composted to contribute to healthy environments. Students also develop an understanding of where their food waste goes when it is thrown away instead of composted.

Students will develop an understanding of the food decomposition process, how landfilled organic waste releases greenhouse gases, and how food scraps can be used to create compost. Lessons introduce strategies that students can commit to as individuals as well as strategies that may take schoolwide effort. The unit culminates with an action plan to help students and the school community waste less food. Pairing action with learning helps students to feel empowered and hopeful.

What Teachers Are Saying

“For my students who may not engage with abstract concepts, the real-life relevance of turning waste into soil for growing plants offers a clear, meaningful goal that they can understand and feel proud to participate in.”

Elementary School
Teacher

“My kids have said, ‘Oh good, I like doing this,’ when we were starting the lesson each day. It’s a great topic. I also think it has made them more curious and do their own research.”

Elementary School
Teacher

“From my students: ‘Thank you for teaching us this lesson because if you didn’t it would be bad for our environment.’ ‘This was awesome! Can you do more? Thank you!’ ‘Thank you for helping us in taking care of the environment.'”

Elementary School
Teacher

“WOW! What incredible and engaging lessons to do with my students. They loved this opportunity to be scientists, explore and think about the food they eat, and I loved the ways that they began to model. I am so excited about these lessons and cannot wait to share them with my coworkers.”

Elementary School
Teacher

“Students really wanted to share their food traditions and look into how climate change might affect their food traditions.”

Middle School
Teacher

“I love how the data was more interactive and chunked into smaller pieces. I also like how there was a way to bring all the knowledge and wondering back to come up with a conclusion to the problem.”

Middle School
Teacher

“This lesson brought in cultural stories from the original people who inhabited California. This is a perspective that is not often taught in science. I think that the kids liked having science be a little less facts and figures and more story.”

Middle School
Teacher

“Students really enjoyed the hands-on activity. They were very interested to learn about the different pollutants that they’ve never heard of. It also developed their curiosity about air quality and pollution. It was an eye-opener for some that they are able to see what is mostly ‘unseen’ by everyone.”

Middle School
Teacher

“Using the maps and seeing things like schools and how close they are to hazards is really cool. They may not be super connected personally, but they can put themselves in the shoes of other kids and try to relate. I know it’s working because I have a kid that just watches Netflix all day, every day and he pulled out his earbud and participated!”

High School
Teacher

“Every lesson was so thoroughly designed, the case study design book was beautifully organized, and it helped to give my class a real-life understanding of how college/graduate-level academic research works. Being able to connect their research back to environmental issues they actually experience was simply icing on the cake. Well done!”

High School
Teacher

“When you’re out in the workforce, you’re trying to solve problems that don’t have a clear, immediate answer. So doing stuff like this helps give students practice.”

High School
Teacher

“I am so amazed and impressed by the depth of resources that you embedded in the teacher guide. This is really well put together.”
